Frequently Asked Questions About Horizon Solar Power

Will solar work on my roof?

There are four main factors to consider when determining if your roof can support solar: orientation, shading, surface, and durability.

  1. Orientation—Solar panels are most efficient when facing south because they receive sunlight all day long in that position. A solar system can be operational facing another direction, but the system’s efficiency may decrease.
  2. Shading—Roofs that aren’t excessively shaded by trees, buildings, or other obstructions produce the most energy.
  3. Surface—Your roof must have enough space to support your solar panels. Roofs with steep slopes or multiple chimneys may prevent solar panel installation.
  4. Durability—Before solar panel installation, consider the age of your roof. If it needs to be replaced in the near future, replace it before installing your solar panels.

Will my solar panels need maintenance?

Solar panels rarely need major repairs, but you should clean your panels twice a year with soap and water. Additionally, call a solar professional to inspect your panels every three to five years to make sure your system remains in good condition.

Can solar panels be recycled?

Yes. Once your panels reach the end of their life, there are recycling programs for your old or damaged system.
