It depends on the technology and the climate the system is placed in.
Thanks to our mild weather, we should see extended lifespans on our systems. A&R Solar also takes care to use best practices developed in our climate. That means you’re getting a system designed for you, not by someone in another state that doesn’t understand our local micro-climates.
Generally, solar electric panels will produce power for 30-50 years. Manufacturers usually warranty the power output for 25 years, but most people agree they’ll continue producing well beyond.
For solar hot water, the collectord that.s usually have 10-year warranties and are expected to last 15-20 years.
In most cases, the balance of system (BOS) components will need to be replaced at some point; think 15-20 years out. This includes parts like pumps, automatic valves, inverters and sometimes storage tanks.
Personally, A&R Solar offers an industry-leading 10-year craftsmanship warranty on all our solar installations.
