Over the last decade, solar power has become a more popular and viable option for powering homes in America. The ability to harvest and use your own energy has many money saving benefits and can help you reduce your reliance on the grid.
But if you are looking to take the next step and gain total independence from your power utility company by using your excess solar power even at night, you may be asking yourself: “Can solar power be stored?”
The Rise of Battery Storage
Improvements in solar panel efficiency have helped offset the cost of installing a home photovoltaic (PV) system. In fact, the average cost of a PV system has gone down 65% in the last decade.
Net metering with local utility companies has also offered valuable financial benefits to homeowners with a solar PV system. Net metering is when a power company buys back the excess energy that a residential PV system harnesses during the day. At night, when solar energy production is low, the PV system uses this utility credit to draw power from the grid. Some utility companies, however, have been changing how they approach net metering — like in Hawaii where net metering has been discontinued altogether.
Fortunately, there is a way to gain virtually complete independence from the grid: using a battery to store your excess solar power. These lithium-ion batteries have also dropped significantly in price in the last four years, in large part because of the popularity of electric vehicles. So, you can now harness the power of the sun to power your home 24 hours a day, without having to draw from the power grid at night.
How Battery Storage Works
Battery storage is most commonly used on systems that are off the grid. These batteries store your excess energy during the day, and then use that saved energy at night to provide uninterrupted power. This works especially well since your home uses much less power at night.
Battery storage may also be used in grid-tied systems to further reduce reliance on the grid or provide backup power if other energy systems fail. Battery storage can also give you further control over when you draw power from the grid.
Are You Looking to Go Solar?
As these technologies get more efficient and more affordable, going solar with your Denver, CO, San Antonio or Austin, TX home is becoming much easier. A PV system will save you money each month on your energy bills, eliminate your reliance on the grid, and reduce your environmental impact. The experts at CAM solar can get the right PV system and battery installed in your home, so you can start reaping the benefits of powering your house with the sun’s rays, day and night.
