Installation costs and process


Before the no-obligation site visit, SunWatt reportedly sets out to put together a preliminary design with Aurora Shade Analysis software. The next step in the installation process is to schedule a comprehensive site evaluation. This face-to-face is the perfect opportunity to discuss design, material selection, incentives, and financing.

Their first financing option is through Westerly Community Credit Union, which offers a fixed-rate solar loan with no upfront fees. A credit score of 700+ is required for the lowest rates. In addition, Sunlight Financial is a national solar loan provider that offers loans with low rates and upfront fees.

Solar loans are offered for 10, 12, 15, and 20-year terms with a 3.99% fixed rate on 10 and 12-year loans and a 4.99% fixed rate on the 15th and 20th years. Homeowners can also opt to pay a portion of the product in cash and finance the remaining balance.

 SunWatt states that solar installation costs will vary depending on the size of the solar system, incentive eligibility, and equipment specs.
