Do Solar Panels Work in a Blackout

February 5, 2020 | Blog

Solar panels require the sun’s energy to keep your home’s electricity running. During a blackout, the sun’s still up, so would the panels still work? This answer depends on the type of solar power systems in place – whether they’re battery backed up or grid tied.

Battery Backed System

If you have a battery-backed system, your electricity will keep on running because the battery system is independently wired from the grid. While your solar system works during the day to convert direct current (DC) energy to alternating current (AC) energy for your home to use, the excess solar energy is stored in the battery. If the battery is a large enough size, it can store enough energy to leave you light for the night. A large battery will protect you when the grid-wide blackout occurs, keeping your electricity running even in winter with less solar exposure.

Grid Tied 

On the other hand, residential solar panels connected to the grid will not be as fortunate. Unlike the battery-backup system, grid-tied systems do not save the excess energy for later use. Rather, the energy is placed back onto the grid for later use. When solar systems detect that the grid power is down, the system will automatically shut down in order to protect utility workers’ safety and home appliances in danger of damage.


While all this may sound a bit daunting, remember how much you could be saving by considering a solar panel installation. Solar panels help you save money by trading your excess energy into utilities and help you keep the environment free from burning fossil fuels. It’s a win-win situation.

What Our Customers Have To Say

Good Rebates

This is a review for a complete HVAC system replacement from Big Mountain. I started at the SMUD website looking for the best rebate program and found a list of contractors there. I vetted out companies that had a lower number of completed jobs per the SMUD rebate program data.

Very Professional

Had my A/C go out yesterday, called Big Mountain today and they had a serviceman in my area of Lincoln, he was here within a half hour and fix my unit in a very professional manner, and the cost was reasonable. I was very impressed with the company and the serviceman.

I had a appointment with them between 1-3 and one of their staff members called me and kept me updated when they will arrive which was nice. Steve arrived on time and was really nice for explaining what could the cause be. My ac fan was working but cool air wasn’t coming out.
