If you’re thinking about going solar, great! The first step to being a proud solar owner is to check to see if your roof is a good candidate by asking yourself these questions…
What direction does your roof face?
The ideal roof for solar faces south at 180 degrees true orientation (or 195 degrees if using a magnetic compass) to maximize the amount of sunlight that your panels receive. However, roofs that are slanted east or west can still be good candidates if they meet the other requirements.
Do you have enough room for solar panels?
Roofs without dormers, skylights, or chimneys are good matches for solar. Most Solar (PV) systems use between 20-30 panels and, with each panel taking up 18 square feet, you should ensure that your roof has approximately 400-600 square feet of open space.
Is your roof slanted or flat?
Roofs with a slant of 30-45 degrees are the best candidates for solar. Flat roofs can also accommodate solar, however, the mounting system will be different from panels on a slanted roof.
What is your roof made out of?
You can attach solar panels to most surfaces, with shingles being the easiest and most popular material. Moreover, if your roof is slate or clay, installers need to take extra care during PV installation because these materials are more prone to breakage.
Is your roof showing signs of old age?
If your roof is showing signs of age such as cupping or lifting, you should consider replacing it before installing a PV system. Therefore, removing a PV system is costly and time-consuming, so ensuring your roof’s quality beforehand can help avoid this.
The poor condition of the roof pictured above means you should replace it before installing solar panels.
Does your roof spend a lot of time in the shade?
Ideally, your panels should receive sunlight between 9 am and 4 pm, ensuring at least six hours of continuous exposure. Additionally, shading from trees, buildings, or roof features like dormers and chimneys can reduce your PV panels’ electricity output.
The easiest way to determine if your roof is a good candidate for solar panels is to call Boston Solar for a free consultation at (617) 858-1645.
