How Is Solar Energy Stored?

Ways in Which Solar Enery is Harnessed in San Diego, CA

You’ve decided to get residential solar panels for your home and you know during the day they will create energy you’ll use to power your home. But what happens when the sun goes down? Read on to find out how the solar power harnessed during the day is stored. 

Although solar panels don’t produce much energy on cloudy days or during the nighttime, the energy they produce during the day can be stored in a rechargeable battery. The panels charge the battery during the day, and then at night the energy in the battery can be used. The battery is connected to an inverter and a controller, which prevents overcharging. With home solar panel installation, the batteries typically last for around a decade and can be repeatedly charged and discharged to about 80 percent of their total capacity. Battery systems are easy to operate and can usually be controlled using a smartphone app, which is often tied in to monitor the solar panels as well. 

Battery storage is essential for rural customers of those who choose to live off the grid. Most residential batteries are small, can be wall mounted indoors or out and can turn on automatically in the event of an outage. 

Some customers choose to sell their excess energy back to the grid. Creating cost-effective storage solutions for excess residential solar power can not only help regulate the energy supply, but it can be essential in times of a natural disaster when traditional power sources are down. If residential customers opt to tie into the grid, in the event that insufficient energy is generated by their solar panels, electricity from the grid well is taken to supplement the deficit. 

If you have a solar hot water system, storage is simpler. Water flows through collectors attached to the rood and then goes to a storage tank where it is stored until needed.
