Note: Your electric bill includes a variety of charges, including a base charge and a per kilowatt-hour charge that varies based on your electricity usage. When you install a rooftop solar system, you will still be required to pay your monthly base charge, in addition to any charges for electricity when solar is not available. Other fees may also apply – contact us to learn more.

Estimated Results*
These results are estimates based on your answers to the questionnaire and include various assumptions. Your new electric bill and estimated savings may vary. You can also experiment with different system sizes to see how your results may change. Estimated system prices can also be adjusted to incorporate quotes you may have received from solar installers.

TAX CREDITS:
Solar systems installations between 2022-2032 are eligible for a 30% tax credit. Tax credits are dependent on your personal tax situation. Be sure to consult a tax specialist to determine if you qualify. Learn more.
