Just Bought a House With Solar Panels? Here's What Nobody Told You.

By Miguel, Elite Pressure Wash Services · Bakersfield, CA

You bought the house. It came with solar. Nice.

Then you realize nobody gave you a manual. You don't know who installed it, whether it's working right, or whether you're even supposed to do anything with it.

That's normal. Here's where to start.

1. Find out if you own it or lease it

This is the big one. Look through your closing documents. If the system is leased or on a PPA (a power purchase agreement), it should have been transferred to you as part of the sale, and you'll have a monthly payment and a contract with the solar company. If it's owned, it came with the house and it's all yours.

It changes who you call when something goes wrong, and who's responsible for maintenance.

2. Get access to the monitoring app

Most systems have an app or website that shows how much power your panels make each day. The previous owner may still be the one logged in. Contact the installer or the inverter manufacturer to get the account moved to your name.

That app is the only easy way to know if your system is working.

3. Track down the paperwork

You want three things: who installed it, the panel and inverter warranties, and the date it was installed. Check with the previous owner, your realtor, or look for a sticker on the inverter, usually a box mounted on the side of the house or in the garage.

4. Make sure it's actually working

Once you're in the app, look for any alerts. Check that the system is producing power on sunny days. If it's showing zero or an error, call the installer.

5. Look at the panels

From an upstairs window, the backyard, or across the street. Clean panels look dark and glossy. Dirty ones look tan or hazy. Look for white spots from bird droppings, and listen for pigeons on the roof in the morning.

6. Get a clean starting point

This is the one most new owners skip. You have no idea when the panels were last cleaned. In Bakersfield, where we go months without real rain, it could have been years.

Starting with clean panels gives you an honest baseline. After that, the numbers in your app mean something. If production drops later, you'll know it's real and not just the dirt the last owner left behind.

The bottom line

Inheriting a solar system doesn't have to be confusing. Figure out if you own it, get into the app, find the paperwork, and start with clean panels so you know what normal looks like for your house.
