Solar panels collect energy from the sun and convert it into electricity for use in the home. When the sun sets, and solar energy is not producing, your home is forced to pull electricity directly from the grid. Batteries store extra energy produced from solar panels to be used later so that you don’t have to purchase energy from the grid. When the sun isn’t shining or during high peak times when you need more energy than your panels can produce, a battery can offset expensive grid power.
Keep the Lights on with a Solar Battery
Solar is one of the most abundant renewable energy sources. And it’s no wonder homeowners are turning to it now more than ever before. Solar gives homeowners control over their energy costs and decreases reliance on the grid. But it doesn’t stop there. Newer technology from solar batteries brings an added bonus – access to saved energy when you need it the most. With more time spent at home, homeowners are realizing the benefits of adding storage to their solar systems.
For most homes, disconnecting from your utility energy grid would require an extremely costly and unique set up. The high cost would outweigh most of the benefits and may not make economic sense. With the right design for your specific energy needs, however, a solar system and battery can work together with the grid to create more savings and independence.
Solar batteries won’t decrease the overall amount of energy you need or choose to use at any given time, but they will help to offset any upcharges should you need to use more than your solar system is producing. Depending on the slope and location of solar panels on your roof, energy production will fluctuate. When the system is at optimal production, extra energy will be stored in your battery for use when the sun goes down. A solar battery is a smart and safe investment with rate plans on the rise and continually changing.
What solar battery should I buy?
There are three main things to consider when comparing batteries: energy capacity, roundtrip efficiency, and warranties.
Energy capacity (depth of discharge) relates to the percentage of energy that is available for use. Batteries with a high-power rating can power several appliances while batteries with lower scores are only capable of powering a few devices at one time. Understand that the more power a battery puts out at one time will also deplete the battery’s storage faster. Finding a battery with a capacity that meets your specific needs is essential.
Roundtrip efficiency is the amount of stored energy that can be pulled from your battery over its lifetime. Like any battery, the life cycle decreases each time it drains and recharges. A battery with a higher roundtrip efficiency will provide the best return on investment as it relates to the overall amount of energy you can use from the system.
Battery warranties guarantee the percent of energy capacity a battery gives for a certain amount of time. Higher quality batteries generally offer a better warranty from their manufacturer. The Tesla Powerwall, for example, produces a discharge of 90 percent and guarantees to maintain at least 70% capacity with Tesla’s 10-year warranty.
