One of the most important factors when installing solar panels for homes is the orientation of the house. Your solar panels should face south in order to maximize the collection of the sun’s energy. If your roof doesn’t have southern exposure, or if there are obstructions to a southern exposure like trees or other homes, we may consider land mounted solar panels rather than roof mounted panels.
While facing south is an important factor, the angle of the panels is related. The pitch of your roof refers to how steep it is. When installing solar panels for homes, its ideal to install them at an inclination of 40 degrees plus or minus 15%, facing south. If your roof is steeper, solar panels may be land mounted in order to receive maximum sun exposure. If your roof isn’t quite as steep, solar panel mounts can be configured to achieve the proper sun exposure.
When sizing solar panels for homes, the construction of your roof and its effective areas are determining factors. The space available for ideal solar panel installation and the load ratings for your roof must be taken into account in order to safely and effectively install your solar panels. Roof mount solar panels have a size range from 3 to 10 kilowatts of installed capacity, while land mounted solar panels are usually larger, up to 20 kilowatts. Your desired installed capacity will be taken into account to determine if your roof is ideal for installation, or if solar panels should be installed on land.
