Why is my electric bill so high when i have solar panels

For over a decade, the residential solar industry in the United States has been propelled by a compelling financial narrative: the promise of the "zero-dollar" electric bill. This prospect—of achieving total energy independence and insulating one’s household from the vagaries of utility rate inflation—has driven millions of Americans to install photovoltaic (PV) systems. However, as the installed base of residential solar has matured and utility regulatory frameworks have evolved, a dissonant reality has emerged. A significant and growing cohort of solar adopters report that, despite their systems functioning within technical specifications, they continue to receive substantial monthly utility statements or are hit with unexpectedly large annual "true-up" bills.
This investigative report provides an exhaustive analysis of this phenomenon, often termed the "Solar Paradox." It challenges the reductive explanations often found in consumer forums—such as accusations of utility "scams" or hardware failure—and instead identifies a complex convergence of factors. These include structural changes in Net Energy Metering (NEM) policies, the proliferation of Time-of-Use (TOU) arbitrage, the rise of non-bypassable fixed charges, and quantifiable shifts in consumer energy consumption behaviors known as the "Solar Rebound Effect."
By synthesizing data from regulatory filings, technical manuals, academic studies, and verified user reports from platforms such as Reddit and specialized energy forums, this document serves as a definitive guide for homeowners, industry stakeholders, and policy observers. It dissects the disconnect between solar production data and utility billing, explains the "invisible" energy flows that confuse consumers, and provides a granular economic analysis of why the era of the guaranteed zero-dollar bill has largely ended for new adopters in major markets like California, Arizona, and Florida.

1. The Measurement Disconnect: Solar Production vs. Net Usage

One of the most pervasive sources of consumer friction in the residential solar sector is the discrepancy between the data displayed on a homeowner’s solar monitoring application and the figures presented on their monthly utility bill. To the uninitiated, this mismatch often looks like evidence of theft or malfunction. In reality, it is the result of a fundamental misunderstanding of electrical topology and metering points.

1.1 The Topology of Energy Flow

To understand why a solar app might report 500 kWh of generation while a utility bill reports only 200 kWh of export credits, one must first visualize the electrical architecture of a grid-tied home. There are three distinct flows of energy, yet the utility revenue meter—the device that determines the bill—is typically only capable of measuring one of them.

1.1.1 Production (The Source)

Solar Production is the gross amount of electricity generated by the photovoltaic panels. This energy starts as Direct Current (DC) and is converted to Alternating Current (AC) by the inverter.

Measurement Point: This data is measured internally by the inverter (e.g., devices from manufacturers like Enphase, SolarEdge, or Tesla).
Visibility: This is the large, green number prominently displayed on the solar monitoring app. It represents the total potential energy the home created. 1

1.1.2 Self-Consumption (The Sink)

Self-consumption refers to the solar energy that is used immediately by the home’s electrical loads—refrigerators, HVAC systems, lights, and "vampire" loads—before it ever leaves the house’s main electrical panel.

The Physics of Flow: Electricity follows the path of least resistance. When a solar inverter pushes current into the main panel, that current will naturally flow to active breakers within the house (e.g., the air conditioner) before it flows out to the utility grid.
Visibility: Crucially, standard utility revenue meters are "blind" to this activity. If a home generates 5 kW and consumes 5 kW simultaneously, the utility meter sees 0 kW of activity. The meter does not spin forward, nor does it spin backward. To the utility, the home appears dormant. 1

1.1.3 Net Grid Interaction (The Gatekeeper)

This is the only flow the utility bill reflects. It measures the net difference between production and consumption at the point of interconnection (the meter).

Import: When household demand exceeds solar production (e.g., at night or during cloudy weather), power flows in from the grid.
Export: When solar production exceeds household demand (e.g., a sunny afternoon with no AC running), power flows out to the grid.

1.2 The "Invisible" Energy Phenomenon

The primary reason homeowners believe their utility is undercounting their production is that they are conflating "Production" with "Export." A user on the r/SolarDIY forum articulated a common grievance: "My app says I generated 375 kWh this month, but the city only gave me a credit for a fraction of that. Where did the power go?". 4
The power did not disappear; it was consumed on-site. The financial value of this self-consumed energy is realized in the form of avoided cost—the homeowner did not have to buy that electricity from the utility. However, because this value appears as a "lack of a charge" rather than a positive "credit" on the bill, it is psychologically less visible to the consumer.
Table 1: Data Visibility Matrix by Monitoring Type

Data Stream	Visible on Standard Solar App (No Consumption CTs)	Visible on Utility Bill	Explanation
Gross PV Generation	YES	NO	The utility does not meter what happens behind the main breaker.
Instant Self-Consumption	NO	NO	Invisible to both the basic app and the utility meter.
Grid Import (Buying)	NO	YES	Measured when load > generation.
Grid Export (Selling)	NO	YES	Measured when generation > load.
Net Usage	NO	YES	The summation of Imports minus Exports.

1.3 Hardware Limitations and Installation Errors

A critical finding from user reports is that many solar installers do not install Consumption Current Transformers (CTs) as a standard practice, or they install them incorrectly. Consumption CTs are sensors clamped around the main service lines that allow the solar inverter to "see" the grid side of the equation.

The "Production Only" Blind Spot: Without consumption CTs, the solar app can only report what the panels are doing. It cannot report what the house is using. A homeowner might see a graph showing 40 kWh of production and assume their 30 kWh usage day was covered. Without the consumption data overlay, they cannot see that their usage actually spiked to 60 kWh, leaving a 20 kWh deficit. 5
Installation Failures: Even when CTs are installed, errors are common. A Reddit thread discussing Enphase discrepancies highlighted that if CTs are clamped on the wrong phase or oriented backwards, the data will be garbage. One user noted their installer placed the consumption CTs around the solar conductors, causing the system to mirror production as consumption, rendering the data useless for billing verification. 7
Sampling Rate Variance: Another source of discrepancy is the sampling interval. Smart meters typically record net usage in 15-minute, 30-minute, or 60-minute intervals. Solar apps often report in 5-minute or 15-minute intervals. If a cloud passes over for three minutes, the app might record that dip with high granularity, while the utility meter averages it out over the hour. Over the course of a month, these sampling differences can lead to minor statistical drifts between the two data sets, usually within a margin of +/- 2.5%. 8

1.4 The Psychological Impact of "Net" Logic

The confusion is exacerbated by the way utilities present "Net" data. A bill might show "Net Usage: 100 kWh." A homeowner looking at their app sees "Production: 500 kWh." They instinctively perform the math: If I made 500 and the bill says 100, I must have used 600. While this logic is sound, the bill often obscures the gross numbers.
Some utilities simplify the bill to show only the net result. If the homeowner imported 1,000 kWh and exported 900 kWh, the bill simply reads "100 kWh." This lack of transparency leads users to believe the utility has ignored their 900 kWh of exports, when in fact they have simply netted them against the imports mathematically. As noted in a discussion on r/Solar, the utility meter's job is to act as a cash register for the grid, not a scientific instrument for the home's total energy physics. 9

2. The Policy Shift: The Erosion of Net Metering Economics

While measurement confusion explains some perception issues, the primary driver of actual high bills is the fundamental shift in Net Energy Metering (NEM) policy. The regulatory landscape has moved from incentivizing solar adoption to managing grid saturation, creating a financial environment where solar energy is worth significantly less than it was a decade ago.

2.1 The Golden Era: NEM 1.0 and 2.0 (Retail Rate Parity)

Under early NEM policies (NEM 1.0 and 2.0 in California, and similar policies in states like Florida and New Jersey), the electric grid functioned as a virtual battery with 100% efficiency.

The Mechanism: If a homeowner exported 1 kilowatt-hour (kWh) of solar electricity to the grid at noon, they received a billing credit equal to the full retail price of that electricity (e.g., $0.25).
The Benefit: Later that evening, when the sun was down, the homeowner could draw 1 kWh from the grid and use that credit to pay for it. The transaction was a 1-for-1 swap.
The Expectation: This model cemented the public expectation that "offsetting usage" meant "offsetting cost." As long as the solar system produced the same number of kWh as the home consumed annually, the bill (excluding minimum connection fees) would be zero. 10

2.2 The Paradigm Shift: NEM 3.0 and the Net Billing Tariff

In April 2023, the California Public Utilities Commission (CPUC) implemented the Net Billing Tariff (NBT), colloquially known as NEM 3.0. This policy change, applicable to customers of PG&E, SCE, and SDG&E, decoupled the value of solar exports from retail rates.

2.2.1 The "Avoided Cost" Valuation

Under NEM 3.0, exports are no longer credited at the retail rate (the price to buy power). Instead, they are credited at the "Avoided Cost" rate—essentially the wholesale price the utility would have paid to purchase that electricity from a commercial power plant.

The Valuation Gap: While a homeowner might pay $0.40 to $0.50 per kWh to import electricity in the evening, they might only receive $0.04 to $0.08 per kWh for the solar energy they export during the day. 12
The Economic Consequence: This 75-80% reduction in export value breaks the 1-for-1 model. A homeowner can no longer simply match their consumption volume. To offset the cost of buying 1 kWh from the grid at night, they might need to export 5 to 6 kWh during the day.

2.2.2 The Avoided Cost Calculator (ACC)

The pricing mechanism for NEM 3.0 is dynamic, governed by the Avoided Cost Calculator (ACC). This tool sets export rates based on the hour of the day and the month of the year, reflecting the grid's actual need for power.

Spring Afternoons (Low Value): In April and May, California's grid is often flooded with solar energy. Consequently, the ACC sets the export credit to near zero during midday hours, signaling that the grid does not need more power. 14
Late Summer Evenings (High Value): In August and September, specifically during the "net peak" hours of 5:00 PM to 8:00 PM, export credits can spike significantly (sometimes up to $2.00/kWh or more during critical events). However, residential solar systems typically produce little to no power during these hours as the sun is setting, making it difficult for solar-only customers to capture this value. 12

2.3 Grandfathering and the Legacy Trap

A crucial distinction for homeowners investigating high bills is their "legacy" status. Systems installed prior to April 15, 2023, in California are generally "grandfathered" into NEM 2.0 for 20 years.

The Misconception: Many grandfathered customers incorrectly assume they are immune to bill increases. However, while their structure (1-for-1 credits) is protected, their rates are not. If the retail price of electricity rises from $0.25 to $0.45, their imports cost more. If their system degrades or their consumption increases (see Section 5), the deficit they must purchase from the grid is billed at these new, historically high rates. 16

2.4 Beyond California: The National Trend

While California is the most prominent example, similar devaluation trends are occurring elsewhere.

Hawaii: As a pioneer in high solar penetration, Hawaii ended net metering years ago. The state now utilizes "Smart Export" and "Customer Grid Supply" programs that, like NEM 3.0, do not offer full retail parity, forcing homeowners to rely on battery storage to avoid high bills. 17
Arizona (SRP): The Salt River Project (SRP) offers price plans that specifically penalize demand spikes (see Section 3) and offer average export rates that are significantly lower than retail import rates, averaging around 2.8 cents/kWh for exports versus 10-12 cents/kWh for imports on certain plans. 18

3. The Economics of Time-of-Use (TOU) Rates

Parallel to the erosion of export credits, utilities have restructured how they charge for electricity consumption. The universal shift toward Time-of-Use (TOU) rates has created a temporal trap for solar owners who do not align their usage with the sun.

3.1 The "Duck Curve" and Rate Design

The "Duck Curve" is a graph representing the net load on the electrical grid. As solar production peaks at midday, the net load drops (the belly of the duck). As the sun sets and people return home, the load ramps up steeply (the neck of the duck).

Utility Response: To manage this ramp, utilities price electricity to discourage usage during the evening peak and encourage it during the midday dip.
The Peak Window: The standard "On-Peak" window has shifted. Historically, it was midday (12 PM – 6 PM). Now, across major utilities like PG&E, SCE, and SDG&E, the peak window is typically 4:00 PM to 9:00 PM. 19

3.2 The Solar Misalignment

This shift in peak hours is mathematically hostile to solar-only installations.

Off-Peak Production: Solar panels generate the vast majority of their energy between 9:00 AM and 4:00 PM. Under TOU plans, this is "Off-Peak" or "Super Off-Peak" time, meaning the electricity generated is valued at the lowest possible rate.
On-Peak Consumption: The typical household peak usage occurs between 5:00 PM and 9:00 PM—cooking dinner, running the dishwasher, watching TV, and using lights. This consumption occurs exactly when solar production is fading to zero and electricity prices are at their highest. 21

Table 2: Hypothetical TOU Arbitrage Loss (Solar-Only Home)

Time Period	Activity	Rate (Import/Export)	Net Financial Impact
12:00 PM	Export 10 kWh	$0.25 / kWh (Credit)	+$2.50 Credit
7:00 PM	Import 10 kWh	$0.55 / kWh (Charge)	-$5.50 Charge
Daily Total	0 kWh Net Energy		-$3.00 Cost

In this scenario, the homeowner has "net zeroed" their energy usage (10 out, 10 in), but because of the price differential, they still owe the utility money. Over a month, this daily discrepancy accumulates into a significant bill. 22

3.3 Seasonal Baselines and Tiers

California utilities further complicate TOU rates with "Baseline Allowances."

The Mechanics: Every household is allocated a "baseline" amount of energy per day (e.g., 15 kWh) that is charged at a lower Tier 1 rate. Usage above this baseline is charged at a higher Tier 2 rate.
The Solar Trap: Solar generation is netted against usage before the baseline calculation. This is generally good. However, if a solar system is undersized or if consumption rises (Solar Rebound), the homeowner may find themselves consistently pushing into Tier 2 pricing for their evening imports. Since Tier 2 rates can be significantly higher (e.g., $0.50+ per kWh), even a small amount of "uncovered" usage becomes expensive. 19

4. The Hidden Regulatory Costs: Non-Bypassable Charges

Even if a homeowner masters the TOU arbitrage and has a grandfathered NEM 2.0 system, they often find that their bill is never truly zero. This is due to the proliferation of Non-Bypassable Charges (NBCs) and fixed fees that are immune to solar offsets.

4.1 Defining Non-Bypassable Charges (NBCs)

NBCs are fees mandated by state regulators to fund public goods, grid maintenance, and legacy debts. Crucially, these charges are assessed on every kilowatt-hour of electricity delivered by the utility, regardless of how much energy the customer exports later.

The Mechanism: If a home draws 1 kWh from the grid, it incurs NBCs. Even if the home exports 10 kWh an hour later, the NBCs associated with that initial 1 kWh import remain. They cannot be netted out. 25

Components of NBCs (California Example):

Public Purpose Programs (PPP): Funds used for low-income assistance (CARE/FERA) and energy efficiency rebates.
Nuclear Decommissioning (ND): Costs associated with safely retiring nuclear plants like San Onofre and Diablo Canyon.
Wildfire Fund Charge: A newer charge established to create an insurance fund for catastrophic wildfire liabilities, paid by all ratepayers connecting to the grid.
Competition Transition Charge (CTC): Legacy costs associated with the deregulation of the energy market. 27

4.2 The "Minimum Bill" Floor

Most utilities enforce a "Minimum Delivery Charge" or "Base Services Charge" to ensure that solar customers contribute to the fixed costs of grid infrastructure (poles, wires, transformers).

Florida (FPL/Duke): Utilities in Florida have implemented minimum base bills, often around $25 to $30. If a solar customer’s energy usage charge is $5, the utility will automatically round the bill up to the $25 minimum. This ensures the utility recovers the fixed cost of metering and connection. 29
California IOUs: PG&E and SCE typically have minimum daily charges that amount to roughly $10-$15 per month. This amount is due monthly and cannot be paid with annual solar credits. It is a hard floor for the cost of grid access. 31

4.3 The "Income-Based Fixed Charge" Proposal (AB 205)

Looking forward, the regulatory environment is shifting toward even higher fixed charges. California’s Assembly Bill 205 (AB 205) mandates the CPUC to authorize a fixed monthly charge based on household income.

The Implication: While details are being finalized, proposals suggest fixed charges ranging from $24 to potentially higher amounts for high-income households.
Impact on Solar: High fixed charges are detrimental to solar economics because they reduce the "avoidable" portion of the bill. If a bill is $100 and $40 is a fixed fee, a solar system can only theoretically save $60, extending the return on investment (ROI) period significantly. 32

5. The Demand Charge Trap: A peril for the Unwary

While TOU rates are common, some jurisdictions—most notably the territory served by the Salt River Project (SRP) in Arizona—utilize Demand Charges for residential solar customers. This billing mechanism is fundamentally different from volumetric (kWh) billing and is a frequent cause of "bill shock."

5.1 Power (kW) vs. Energy (kWh)

To understand demand charges, one must distinguish between the rate of usage and the volume of usage.

Energy (kWh): Analogous to the distance traveled in a car (miles). Most residential bills are based on this.
Demand (kW): Analogous to the top speed of the car (mph). Demand charges bill the customer based on the highest rate of electricity usage recorded during a specific interval (usually 15, 30, or 60 minutes) within the month. 33

5.2 The "One Bad Interval" Scenario

For a solar customer on a demand plan, a single 30-minute window can destroy the month's financial savings.

The Scenario: It is 6:00 PM in July. The sun is setting, so solar production drops to near zero. The homeowner arrives home and simultaneously turns on the central air conditioning, starts a load of laundry, and begins cooking with an electric oven.
The Spike: The household demand spikes to 12 kW.
The Cost: If the demand charge is $18 per kW (a typical summer rate for SRP), this single event adds $216 to the bill ($18 x 12 kW). It does not matter if the homeowner uses zero electricity for the rest of the month; that peak has been set. 34

5.3 Solar's Inability to Mitigate Demand

Solar panels are poor tools for mitigating demand charges because they are intermittent. A passing cloud can cause production to drop from 6 kW to 1 kW in seconds. If household load remains high during that cloud passage, the grid instantly fills the gap, registering a high peak demand on the meter.

SRP's Price Plans: SRP offers a "Customer Generation Plan" that features very low per-kWh energy rates but high demand charges. This plan is designed to shift the cost burden to peak usage. Solar customers who do not actively manage their load—by staggering appliance usage or using batteries—often find themselves paying more on this plan than they did before solar. 18

6. The Human Element: The Solar Rebound Effect

While technical and regulatory factors are significant, human behavior plays a quantifiable and often overlooked role in high post-solar bills. This phenomenon is known in energy economics as the Solar Rebound Effect (or Jevons Paradox).

6.1 The Psychology of "Free Energy"

The Solar Rebound Effect occurs when households increase their electricity consumption after installing PV systems, driven by the perception that the energy is now "free," "guilt-free," or "green."

Behavioral Drift: A study by researchers at Georgia Tech indicates that after installing solar, households often relax their energy conservation habits. They may keep the house cooler in the summer (lowering the thermostat from 78°F to 72°F), leave lights on longer, or run appliances more frequently. 37
User Testimonials: A candid admission on Reddit illustrates this perfectly: "Before installing solar panels, we were more cautious... washing dishes by hand... limiting heating. Now, with solar power, we use electricity more freely. We run the heating more in winter and keep the air conditioning on all day." The user noted their bill did not drop as much as expected, directly attributing it to this lifestyle inflation. 38

6.2 Quantifying the Rebound

Academic research attempts to put a number on this effect.

Magnitude: Studies suggest a rebound effect ranging from 18% to 20%. This means that for every 1 kWh of solar electricity generated, the household increases its total consumption by roughly 0.18 kWh. 39
The Offset Gap: If a solar system was sized to cover 100% of a home’s historical usage (e.g., 10,000 kWh/year), and the rebound effect pushes usage to 12,000 kWh/year, the homeowner is left with a 2,000 kWh deficit. Under NEM 3.0 or tiered rates, purchasing this deficit from the grid can be prohibitively expensive, negating a large portion of the expected savings. 40

6.3 Electrification and Added Load

A specific subset of the rebound effect is the intentional addition of electric loads. Homeowners who install solar are statistically more likely to purchase Electric Vehicles (EVs) or switch from gas to electric appliances (heat pumps, induction stoves).

EV Impact: Charging an EV can easily add 300-400 kWh per month to a household's load. If the solar system was not originally sized to accommodate this—or if the EV is charged at night (pulling from the grid) rather than during the day (from solar)—the electric bill will inevitably rise. 26

7. Technical Losses and System Performance

Finally, the "high bill" may stem from the physical reality that the solar system is not producing as much energy as the sales proposal predicted. Real-world conditions rarely match the "Standard Test Conditions" (STC) used in laboratory ratings.

7.1 Inverter Clipping

Clipping is a phenomenon where the solar panels produce more DC electricity than the inverter can convert to AC. This is a common design choice known as increasing the DC:AC ratio (often 1.2 or 1.4).

The Symptoms: On a clear, cold spring day, a homeowner might look at their production graph and see a "flat top" or plateau, where production rises to a certain point (e.g., 7.6 kW) and stays there for hours, rather than following a natural bell curve.
The Impact: The energy above that flat line is "clipped" and lost. While installers argue this is economically optimal (it maximizes production during low-light mornings and evenings), homeowners often interpret it as a system failure. If the clipping is excessive due to poor design, it can result in material energy losses that force the homeowner to buy more power from the grid. 41

7.2 Degradation: The Slow Fade

Solar panels degrade over time.

NREL Data: Research by the National Renewable Energy Laboratory (NREL) indicates a median degradation rate of 0.5% to 0.75% per year. In hotter climates (like Arizona or Texas), this can accelerate.
Cumulative Loss: A system that is 10 years old may produce 5% to 8% less energy than it did on Day 1. If the homeowner's consumption has remained steady or increased (Rebound), this degradation slowly widens the gap between production and demand, leading to creeping bill increases year over year. 44

7.3 Soiling and Environmental Factors

Soiling refers to the accumulation of dust, pollen, bird droppings, and wildfire ash on the panel surface.

Location Matters: In arid regions like California’s Central Valley or the desert Southwest, soiling losses are significant. Studies show losses can accumulate at a rate of 0.2% per day during dry spells. Over a long, dry summer, a system can lose 7% to 20% of its monthly output if not cleaned. 46
The Rain Fallacy: Homeowners often believe occasional light rain cleans the panels. In reality, light rain can mix with dust to create a mud-like film that worsens performance. Only heavy, sustained rainfall effectively cleans the array. A dirty system is a lower-producing system, leading to higher grid reliance. 48

7.4 Thermal Efficiency

Solar panels paradoxically perform worse as they get hotter. The "Temperature Coefficient" of a panel dictates how much efficiency is lost per degree Celsius above 25°C.

Summer Performance: On a 100°F day in July, panel temperatures can exceed 140°F. This can reduce instantaneous power output by 10-15% compared to a cool spring day. This thermal loss occurs precisely when air conditioning demand is highest, exacerbating the grid reliance during peak summer months. 49

8. The "True-Up" Bill Shock: A Structural Feature

For customers in NEM territories (especially PG&E and SCE), the monthly bill is often deceptively low, masking a looming debt.

8.1 The Annual Reconciliation

Under many NEM plans, the customer pays only the minimum delivery charges (e.g., $15/month) throughout the year. The actual cost of energy (Imports minus Export Credits) is tracked in a ledger known as the NEM Balance.

The Surprise: At the end of the 12-month cycle, the utility "trues up" the account. If the customer used more energy value than they generated, the entire year's deficit is due immediately.
The Complaint: High True-Up bills (often $1,000 to $3,000) are the most common source of "solar doesn't work" complaints. They occur because the customer was accruing debt all year—perhaps due to the Solar Rebound, rate hikes, or NEM 3.0 export devaluation—but failed to monitor the running balance on their statement. 24

9. The Role of Energy Storage (Batteries)

In the modern regulatory environment (NEM 3.0, aggressive TOU), the "solar-only" model is increasingly obsolete for achieving low bills. Battery Energy Storage Systems (BESS) like the Tesla Powerwall or Enphase IQ Battery have transitioned from luxury backup items to essential economic tools.

9.1 Self-Consumption and Arbitrage

Batteries solve the timing mismatch described in Section 3.

Strategy: The battery charges from solar during the day (when export rates are low). It discharges to power the home in the evening (when import rates are high).
Economic Impact: This prevents the homeowner from selling cheap power and buying expensive power. Under NEM 3.0, adding a battery can increase the bill savings of a solar system from roughly 55% to over 90%. 10

9.2 Virtual Power Plants (VPP)

Looking to the future, programs like "Virtual Power Plants" allow battery owners to export stored energy during critical grid stress events for high compensation (e.g., $2.00/kWh). This revenue stream can help offset the unavoidable fixed charges and NBCs that solar alone cannot eliminate. 15

Conclusion

The persistence of high electric bills for solar homeowners is rarely the result of a single catastrophic failure or a malicious scam. Rather, it is the outcome of a complex, evolving energy ecosystem. The "Solar Paradox" arises from the friction between consumer expectations (based on outdated 1-for-1 net metering models) and grid realities (saturation, TOU rates, and fixed infrastructure costs).
Key Takeaways for Homeowners:

Trust the Bill, Not the App: Unless you have correctly installed Consumption CTs, your solar app is only telling half the story.
Understand Your Rates: You are likely buying power at a much higher price than you are selling it. "Net Zero" energy does not mean "Net Zero" cost.
Manage Behavior: The Solar Rebound is real. Conservation is still the most cost-effective way to lower bills.
Embrace Storage: In NEM 3.0 and demand-charge territories, batteries are no longer optional for maximizing savings; they are the primary mechanism for bill reduction.
Audit the System: Check for soiling, clipping, and degradation. A 10% loss in performance due to dirt can translate to hundreds of dollars in grid purchases.

Ultimately, solar remains a powerful hedge against long-term energy inflation, but it requires active management and a nuanced understanding of the billing mechanics. The era of "set it and forget it" is over; the era of the "energy-managed home" has begun.
