Six tips for buying a solar-powered battery

Start with a strong referral or two

It’s great to have a referral from someone you trust who already has a battery.

Make sure they are a CALSSA member

We highly recommend that you look for installers who are members of the California Solar & Storage Association (CALSSA). CALSSA requires all members to sign a code of ethics that commits member companies to consumer-friendly practices. CALSSA also works to keep member companies up to date on all the changing codes & standards and regulations. Find a CALSSA-member installer. 

Make sure their contractor license is current

You can look a company up at the state licensing board.

Check their reviews

Make sure online reviews from Yelp, Reddit, NextDoor, and Google Business are generally good with no major flags.

Make sure they have experience installing batteries

Installing a battery can be complicated, so it is good to go with someone with experience.

Optional: See if they are NABCEP certified

The North American Board of Certified Energy Practitioners (NABCEP) is considered one of the most rigorous training and certification programs in the country. Keep in mind that many good solar installers don’t have this certification, but you might still take it into consideration. Find a NABCEP-certified installer in your area.

What about door-to-door salespeople?

It might be worth listening to their pitch and taking down their information. However, we recommend you do not sign up on the spot with someone at the door. Take their information and look them up, using the tips listed above. If they pass muster, then consider them along with one or two other installers.
