Pay Attention to Solar Warranties and Guarantees

All these solar warranties and guarantees can be confusing, so here are the basics.

Solar panels typically come with a 25 year warranty on the production of the panel.

Which means…

The panel manufacturer guarantees that your solar panels will produce a certain amount of power for 25 years.

Then you have your inverter...

Inverters generally come with a 10 - 12 year warranty, but often you can pay more to extend it to 20 years.

Microinverters usually carry a 25 year warranty.

If your solar system has a battery, there is a warranty on that too.

The other warranties come from your solar installer.

Pay attention to these when you're buying a solar system!

What should you be looking for in an installer's warranty?

Well it’s real simple.

The real value to you is not the length of the warranty, but how much power your solar system is going to produce.

You want a guarantee on that power production.

Cause the energy produced by your solar system makes you money.

For example, a poorly designed system won’t produce as much electricity even with a lengthy warranty.

And if an inverter goes bad, your power production will decrease.

So ask your installer what the power guarantee is.

A good solar company will guarantee your solar system’s performance.

Oh yeah and don’t forget...

The solar company should provide a workmanship warranty also.

So if something does go wrong and a technician has to fix something, there is no additional cost to you.

And you need to monitor your solar system too.

A monitor will show you and your installer how much your solar array is producing.

The solar company should be as invested in your solar system as you are.

So in a nutshell you have...

  • Hardware warranties

  • Production warranties

  • Monitoring

All of this will guarantee that your solar system will produce clean energy and put money in your pocket.
