Before choosing a solar system be sure that your home is as energy efficient as possible; you may want to get a home energy audit from your cooperative to help determine which improvements will be most beneficial. Investing in energy efficiency provides a faster return on your investment. By improving your home’s energy efficiency first you will reduce your overall energy use and may reduce the size of PV system called - that saves more money. Also make sure your roof is in tip-top shape. If yours is older, you may need to repair or replace it before installing solar (and remember, a solar PV system may last up to 30 years, so be sure your roof will last, too). Research solar and solar contractors thoroughly before investing in a system; get at least three quotes before choosing a one. Be sure to work closely with your cooperative for advice and assistance on interconnecting with the grid. They can provide information and history of your energy usage that can help you size your system and evaluate savings. Co-op staff has experience in working with other member-owners and solar contractors.
