Slow Power Degradation

On average, solar panels only lose 0.5 percent capacity every single year.

This means that within 20 years of installation, your panels will operate at about 90 percent of their original capacity.

Due to their material, solar panel degradation is inevitable, but thanks to improvements in technology, your solar panel system function almost perfectly years and years down the road.

Solar Panels Can Last Decades

Many solar panels can last 25 years or more, depending on the type of panel used and where you live.

In addition, your solar provide may also have a warranty that you can take advantage of if you notice lower quality for your system.

The most expensive type of solar panel, monocrystalline, currently has a market lifespan of 25 to 30 years.

If your system is over a couple of decades old, it may be time for an upgrade in order to run a more energy-efficient home.

Clean Panels Regularly

To maximize the use of your solar panels, you should make sure that you clean them on a regular basis.

This can have a positive effect on your solar panel lifespan, as well as your roof in general.

Keeping solar panels in tip-top shape will also ensure that your roof does not need repairs as often.

If debris builds up on top of or around solar panels, then you may also end up wasting more energy than necessary. You can also gently rinse your panels to wash away dirt and grime.

Maintenance is Key

When you get solar panels installed, you should go with a company that will provide maintenance for your solar panel system.

For example, if you live in Richmond, Virginia, you can do an internet search for solar companies near you and compare packages and pricing plans.

A more expensive package with regular maintenance may be worth it in the long run.

You should also monitor your electricity usage from your solar panels.

If there is a significant spike in usage, it can indicate that your home draws too much power from solar panels that are not functioning correctly.
