In our commitment to making solar energy accessible, we've established a partnership with local lender, EastRise Credit Union, a division of New England Federal Credit Union. They offer low fixed-rate home equity loans for up to 15 years. These loans don't require any upfront payment, and there are no penalties for early repayment. By choosing our solar loan option, you can substitute your current electric bill with manageable monthly payments, often resulting in immediate savings.

Quality & Reliability

We take pride in our careful selection of durable products for installation. Every solar panel we use comes with a reliable 25-year production warranty, ensuring long-term performance. Additionally, a majority of the inverters we install boast 25-year warranties, providing comprehensive coverage for both parts and labor—no unexpected surprises. Our commitment to excellence is evident in the quality of our workmanship, backed by a robust 12-year guarantee.
