How do I know if I have enough sunlight for PV?
A PV system needs unobstructed access to the sun's rays for most or all of the day. Climate is not really a concern because PV systems are relatively unaffected by severe weather. In fact, some PV modules actually work better in colder weather. Most PV modules are angled to catch the sun's rays, so any snow that collects on them usually melts quickly. There is thus enough sunlight to make solar energy systems useful and effective almost anywhere in the world. Most homes have adequate roof space for a PV system, and this can be complemented by integrating the system into walls or by using modules to cover a porch or patio in the backyard.| Last update:2008.06.08 Clicks:799
