Solar Energy Battery Storage
Are you concerned with keeping the lights on after a power failure? Or want to reduce your dependency on your utility when the sun goes down? Then you may want to consider installing a solar energy battery storage system. While it can be a great option, they recharge with solar energy, which is free, and they are much more environmentally friendly than a gasoline or diesel generator.
As far as which type of batteries are right for you, there are different types of batteries than can fit your energy goals and budget. The three main types are: Lead-Acid, Lithium-Ion, and Saltwater. They each have their advantages and disadvantages and Royal Solar can help you decide which is best for your situation.
Capacity is the amount of electricity that a solar battery can store, which is measured in kilowatt-hours (kWh). Home solar batteries are designed to be stackable, which means you can have multiple batteries in your system to increase storage capacity.
While capacity tells you how large your battery is, it doesn’t tell you how much power a battery can provide at any given time. You also need to consider the battery’s power rating. For most batteries, a power rating is the amount of electricity a battery can deliver at one time, and it’s measured in kilowatt hours (kWh).
A battery with a high capacity but a low power rating will deliver a low amount of electricity, probably enough to run a few crucial appliances (your refrigerator, for instance), for a long time. A battery with low capacity and a high-power rating could probably run your entire home, but only for a short time.

Types of Solar Storage Batteries
Lead-acid batteries have been around for over 100 years. It’s the kind of battery you’ll find in your car and they’ve been used for off-grid solar systems for several decades.
They come in different types – Wet-Cell or Flooded Lead Acid, Gel Cell, and Absorbed Glass Mat (AGM) batteries. They usually take a lot of room and aren’t as efficient as lithium-ion batteries.
