Will my solar array need maintenance?
There is not a “cookie cutter” O&M plan that will work for every solar array. A list of variables should be considered when deciding how often a solar array needs serviced and the types of service that should be included.
A solar array is an appliance just like your dishwasher or washing machine. Regular inspections can head off potential problems and the resultant loss of productivity. Regular maintenance will ensure that your system is functioning optimally through its lifetime.
This page highlights some of the O&M services we offer, but it is not all inclusive since we perform all sorts of service on solar arrays for homeowners, businesses, municipalities, governments and utilities!
Most homeowners who regularly monitor their solar array can benefit from a system inspection every year or every other year. During that time, the system components will be inspected and the technician will also look for squirrel damage, malfunctioning parts and equipment and will determine whether your array can use a good washing (this can improve productivity!)
If you’ve just bought a house that has solar on it or if you had a system installed and know little about it, start with this article, as it provides you with lots of good information. Also, if you don’t have solar monitoring, we strongly encourage you to acquire it. More on solar monitoring here.
Larger commercial systems can also benefit from an annual inspection. Panel washing depends on the array’s location and whether pollen, tree sap and dust are an issue.
Service and maintenance on a solar array, regardless of location or size, can absolutely benefit the overall longevity of a solar array and the lifetime value of its components. It is better to be proactive and catch a potential problem before it becomes one rather than wait until the problem surfaces then have to face partial or whole array outage while the service call is being scheduled and the subsequent part is being shipped.
