SOLAR BATTERY STORAGE
Solar batteries have become increasingly common for homeowners who want a backup power solution. Grid tied solar systems don't require solar batteries, so determining if they're the right backup solution is critical when you go solar. Check out the resources below to help you decide if solar battery storage is the right fit for you.
At Kokosing Solar, we guide people to Solar Energy Storage when it aligns with their goals for a backup power solution. What type of goals would align a homeowner with solar battery storage?
Assures power in the event of a grid outageÂ
Solar Energy Storage increases the self-consumption of solar power generation. Solar batteries can store surplus solar energy during daylight hours and use that energy later when the sun is not shining.
Battery storage can charge during low rate periods when demand for electricity is lower, and discharge during more expensive rate periods when electricity demand is higher.
The video below introduces you to choices you’ll need to consider when designing battery system size that will best meet your goals.
Keep all four of these sizing guidelines in mind as you find the product that will meet your needs.
When we’re sizing a solar battery system for a client, we first look at how much power will need to come out of the battery to kick on all the appliances you want to power. If all the loads you want to run are running simultaneously during an outage, how much power will that take? Â
Next, we look at time. How long do you want to be able to run these loads? Do you want to be able to power these loads for the typical two to four hour utility outage? For a full day? Or for even longer?Â
Consider load management to help further hone in on your battery needs. For example, imagine that you want to be able to run your hot tub during a two to four hour power outage. You can surmise that it will require more batteries to power the hot tub for a twenty four hour power outage. So, if you’re willing to shut off your hot tub if you know the outage will be longer than two to four hours, you will need fewer batteries. Â
The last thing to think about is how much solar you have.  Most solar batteries require a certain number of solar battery units per the size of your solar energy system.Â
Generators provide reliable backup. They automatically turn on during utility failures, and power your home when the sun isn’t shining, and solar batteries are drained. Â
One misconception we hear frequently is that a generator can provide backup power to the same loads as the solar battery, after the battery is drained. Unfortunately, this is not the case. It is not possible for both systems (generators and solar batteries) to back up the same loads. Â
