Disclaimers

The information provided in our proposal is a preliminary estimate for illustration purposes only and is not a binding agreement or obligation. Actual system production or savings is not guaranteed. The system design may change based on a detailed engineering site audit. A solar power system is customized for your home, so its pricing, actual system production, and savings will vary based on the final location, system size, design, configuration, utility rates, applicable rebates, tax benefits realized, and your household’s energy usage.

Financing terms may vary and are not available in all locations. Tax credits and incentives, if any, are not guaranteed.  Our proposal is not an approval for a loan and all financing terms are subject to approval.
