Solar FAQ: Debunking Solar Energy Myths

Frequently asked questions about rooftop solar energy 

Question: If the sun is not out, will I have no power?

The primary requirement for a solar PV system to work is UV light. Direct light works best, but solar modules can still operate with indirect light. Clouds and rain are not opaque barriers through which light cannot get through, meaning sunlight can reflect or partially break through the clouds and reach the rooftop solar energy system. Solar systems are able to operate at night and at other times when the sun is not directly shining on the solar modules because the system harvests and stores unused energy for future use.

Question: Does solar energy only work in hot, always sunny locations?

No! There are many factors that go into determining whether your home is a viable location for a rooftop solar system. The top states for solar power include

  • California,
  • Arizona,
  • North Carolina,
  • New Jersey,
  • Nevada,
  • Massachusetts,
  • New York,
  • Hawaii,
  • Colorado,
  • and Texas,

but by no means is solar energy limited to these states. As you’ll see in the list above, some of the top solar states are in regions that can get very cold! The suitability of a roof for solar power takes into account the direction the roof is facing, the potential for shading of the modules by nearby trees and structures, the condition of the roof, and the type of material on the roof, among other factors.

Question: Will my rooftop solar PV system require a lot of maintenance?

One common misconception about solar energy systems is that they require a lot of maintenance. This may have come about because these systems come with a warranty or agreement that covers the cost of maintenance for a certain number of years. In reality, a properly installed rooftop solar system requires little work to maintain because there are no moving components. Unless you live in a dusty area, hosing off your system is typically unnecessary—that’s what rain does! And, in the unlikely event of solar module damage, your warranty (typically around 25 years) should cover any required repairs.
