A photovoltaic (PV) system needs unobstructed access to the sun for most or all of the day throughout the year. PV panels are relatively unaffected by changing weather and the modules are angled to catch the sun, not snow, so any snow that does collect melts quickly. Here are some important tips that will help you determine if your property is right for PV:
- PV systems are best installed on a southern exposed roof. However, some east or west exposures may also be acceptable.
- PV systems are ideally mounted parallel with the roof. A 30 degree roof pitch is ideal for the Kansas City region. It’s best to ensure there is no shading of the area between the hours of 9 a.m. and 4 p.m. Shading can include trees, chimneys, TV antennas, satellite dishes, dormers and gables.
- A PV system can be installed on any well-structured roof. If your roof is older and needs to be replaced in the near future, you may want to replace it at the same time your PV system is installed.
- The amount of roof space needed for a PV system is based on the output and type of system. Your roof size and orientation will determine how much PV you can install on your roof.
