Is there maintenance required to keep a solar system operational?
Occasionally, a solar array should be rinsed off with a hose to clear the dust or debris that blocks sunlight and reduces efficiency. That’s about all that’s required. There are no moving parts to wear out and Sharp solar modules are covered under limited warranty for power output for 25 years. In fact, there are solar modules that Sharp installed 50 years ago that are still producing energy today.
