Maintenance

One of solar's quiet advantages is how little it asks of you: no moving parts, no fuel, no annual service contract. But "low maintenance" isn't "no maintenance", and a few simple habits keep an array producing at its best for decades.

This hub covers upkeep honestly — what's worth doing, what's a waste of money, and what the over-eager cleaning services won't tell you.

Cleaning, the right way

In most climates rain does most of the cleaning, and the gain from washing panels is smaller than people expect — though dust, pollen or bird droppings in dry areas can be worth addressing. The bigger issue is doing it safely. Our guide on how to clean solar panels safely covers when it's worth it and how to avoid both injury and panel damage.

Keeping output healthy over time

Beyond cleaning, maintenance is mostly monitoring: watching production for unexplained drops, keeping an eye on the inverter, and clearing shade as trees grow. Our broader guide on solar panel maintenance explains what to check, how often, and which warning signs justify a call-out. Read both before you pay for a service plan you may not need.
