Utility bills across Solar Energy World’s service states have risen faster in the past two years than most homeowners anticipated. Pepco customers in Maryland saw bills climb 21.4% in a single year. Pepco customers in Washington D.C. saw a 25.2% increase over the same period. Virginia’s State Corporation Commission approved the state’s first base rate increase since 1992 in January 2026. BGE in Maryland has implemented multiple rate increases with more approved through the year. In New Jersey, four utilities raised rates by up to $28 per month.
The drivers behind these increases are structural: data center demand in Northern Virginia and the Mid-Atlantic has surged, PJM’s capacity market auction for 2025/2026 cleared at an 830% premium over the prior year, and grid infrastructure upgrades are being passed through to ratepayers. US electricity rates have risen 21% in five years and are now averaging 18.05 cents per kWh nationally, with Mid-Atlantic states tracking above that average.
Solar does not change what the utility charges per kilowatt-hour. It eliminates or dramatically reduces how many kilowatt-hours a homeowner buys at that rate. This article explains how that works, what affects the magnitude of the savings, and how Solar Energy World designs every system to maximize bill impact.
How solar reduces a utility bill
Solar reduces electricity costs through two mechanisms: direct behind-the-meter production and net metering credits.
During daylight hours, solar panels generate electricity the home uses directly. Every kilowatt-hour produced and consumed on-site is a kilowatt-hour the homeowner does not buy from the utility at the current rate. When a system produces more electricity than the home is using at a given moment, which is common during peak production hours from roughly 10 AM to 2 PM, the excess flows back to the grid.
In Maryland, Virginia, Delaware, Pennsylvania, New Jersey, and Washington D.C., utilities are required to provide full retail rate credits for that exported electricity. Those credits offset what the homeowner draws from the grid at night, on cloudy days, and during other low-production periods. The net effect, for a well-sized system in a net metering state, is that the grid functions as a free battery: bank excess production during the day and draw it back at no charge in the evening.
A system sized to produce the same number of kilowatt-hours annually as the home consumes can reduce the variable electricity charge on a utility bill to near zero. Homeowners still receive a bill showing fixed monthly charges, typically $10 to $30 depending on the utility, covering connection fees, taxes, and regulatory charges that cannot be offset by solar production. The “up to 100%” figure refers to the energy usage portion of the bill, which is the large majority of what most homeowners actually pay.
With battery storage added, a homeowner can also avoid drawing from the grid during evening peak hours or grid outage events, reducing net costs further.
What determines how much a homeowner saves
The savings from solar are real but they are not uniform. Several variables directly affect the outcome.
System size relative to consumption matters most. A system producing 100% of a home’s annual electricity eliminates the variable energy charge. A system producing 80% eliminates 80% of it. Getting this right requires designing around actual consumption history, not regional averages.
Electricity rate determines how fast savings accumulate. Maryland, Washington D.C., New Jersey, and Florida all have above-average electricity rates. At 20 cents per kilowatt-hour, a solar system producing 10,000 kWh per year delivers $2,000 in annual savings. At 15 cents, that same production delivers $1,500. With rates rising at an average of 2.8% per year nationally, and faster in PJM states, the savings gap widens every year the system is in operation.
Net metering policy is the other critical variable. All of Solar Energy World’s service states currently offer full 1:1 retail rate net metering, meaning every kilowatt-hour exported earns a full credit against future usage. Virginia utilities have proposed future changes to this structure; homeowners who install before any policy change takes effect are expected to be grandfathered under current terms.
Future loads change the sizing equation. An electric vehicle adds 3,000 to 5,000 kilowatt-hours per year to household consumption. A heat pump conversion adds 1,500 to 3,000 kilowatt-hours. A system designed only for today’s usage is undersized the moment an EV arrives. Adding panels after the initial installation costs 30 to 50% more per watt than including them from the start. Solar Energy World incorporates planned future loads into the system design.
What the savings look like in Solar Energy World’s service states
Maryland homeowners avoiding $75,000 or more in utility costs over 25 years is a data point that consistently appears in solar economics analysis for the state. That figure does not include SREC income, which adds $500 to $700 per year for a typical system over 15 years. Combined, purchased system owners in Maryland can realistically expect a 7 to 10-year payback and decades of savings beyond that.
Washington D.C. produces some of the most compelling solar economics in the country. SREC values at $300 to $400 per certificate, the highest in the US, stack directly on top of net metering savings. A typical 8 kW system generating 9 SRECs per year earns $2,700 to $3,600 annually from SRECs alone. Payback periods of 5 to 7 years are realistic.
In New Jersey, the fixed-rate SuSI SREC-II program pays $85 per MWh for 15 years, alongside 1:1 net metering. EnergySage data shows average 25-year electricity cost savings of $86,000 for a purchased NJ system.
Virginia, Delaware, Pennsylvania, and Florida each combine net metering savings with their respective incentive structures. Florida’s case rests primarily on production volume, 237-plus average sunny days per year, combined with full retail net metering, 100% property tax exemption, and 6% sales tax exemption on equipment.
How Solar Energy World designs every system to maximize savings
A system designed for an average home in a region is not designed for your home. Solar Energy World’s in-house engineers design every system using verified, site-specific data.
The process begins with a review of 12 months of actual utility consumption history, establishing the real baseline for how much electricity the home uses and when. Site assessment confirms roof conditions, shading, orientation, and electrical panel capacity. The system is then sized to the homeowner’s actual consumption and planned future loads, not a generic estimate.
Panel and inverter selection is matched to the roof’s conditions. Microinverters allow each panel to operate independently, which is critical on complex or partially shaded roofs where a single underperforming panel would otherwise limit the whole array. The right technology maximizes what the actual roof produces, which directly determines how much of the utility bill the system displaces.
Solar Energy World’s production estimate is what the First-Year Energy Production Guarantee is built on. If the system produces below 90% of its year-one estimate, Solar Energy World reimburses double the shortfall. That provision exists because accurate production estimates and quality installation are what make the savings real.
Both financing paths save money
The structure of the savings depends on whether a homeowner chooses a PPA or a purchased system.
Under the $0 down PPA, Solar Energy World installs and owns the system at no cost to the homeowner. The homeowner pays a locked-in rate at least 20% below what the utility currently charges, and savings begin immediately. SREC income goes to the system owner, not the homeowner. Net metering credits apply. The monthly payment is predictable and insulated from utility rate increases.
Under a purchased system, the homeowner owns the system, captures all bill savings, and in applicable states earns SREC income directly. Solar Energy World offers $0 down financing, so ownership does not require upfront cash. On average, purchased systems generate a 125% return on investment within 5 to 7 years and a 500% return by year 20. After the loan is paid off, the electricity is essentially free.
You can compare both paths side by side at solar pricing and financing options to see which structure produces the better outcome for your specific situation.
