Solar Equipment

If paying for solar panels out of pocket is out of reach, solar loans are an affordable route because they decrease your upfront costs and let you pay for your system over five to seven years on average.When figuring out your overall cost, you should also calculate the interest you’ll pay if you go with a solar loan. Also, paying more on your down payment can reduce the total interest paid over time.
