Estimate your annual electricity savings and 25-year return from going solar — based on your location, usage, and system size.
Solar savings depend on your utility rate, local sun hours, roof orientation, shading, net metering policy, and financing terms. This calculator provides a general estimate. For a precise quote, get proposals from 2–3 licensed installers in your area.

More peak sun hours = more energy generated per kW of installed panels.
This calculator gives a ballpark figure. Real savings depend on your utility's rate structure, whether net metering is available, how much of your generated electricity you use directly vs. export, system degradation over time (typically ~0.5%/year), and whether you finance with a loan, lease, or cash purchase.
Net metering lets you sell excess electricity your solar panels generate back to the grid, earning credits on your bill. Most states have some form of net metering, but policies vary widely — some states offer full retail credit, others offer reduced rates. Check your utility's current net metering policy before going solar.
Yes — solar panels generate power from daylight, not direct sunlight. States like Massachusetts, New York, and New Jersey have some of the highest solar adoption rates because they combine decent sun hours with high electricity rates and strong incentive programs. High electric rates often matter more than peak sun hours.
