Frequently Asked Questions

Does solar always save money?

In most cases, yes, over the lifetime of the system (25-30 years). The exceptions are homes with very low electricity bills (under $60/month), heavily shaded roofs, or regions with extremely low electricity rates and no good incentives. For the average US home paying $150/month, solar saves $30,000-$60,000 over 25 years after system cost.
