What Are Solar Batteries and Why Use Them

How Solar Batteries Work

Solar batteries store power from your solar panels. Your panels make extra energy during the day. The battery saves this energy for later use. You can use stored power at night or when the lights go out. This helps you use more solar power and less grid power.

• Solar batteries take extra power from your solar panels.
• They keep this power until you need it, like at night or when it is cloudy.
• When your house needs power, the battery sends it through an inverter so your appliances can use it.
• The battery uses chemicals to hold and give out energy.

Solar batteries make your solar system work better. You get power even when the sun is not out.

Key Technical Terms for Solar Batteries

Depth of Discharge (DOD)

You should know how much energy you can use from your solar battery. Depth of Discharge (DOD) tells you what percent of the battery’s energy you use before charging it again. DOD is like a fuel gauge for your battery. If you use more energy, the battery works harder and may not last as long. Experts say you should keep DOD between 20% and 80%. This helps your battery last longer and work better.

• Keeping DOD in the safe range helps your battery last longer.
• Using DOD the right way saves money and keeps your battery healthy.
• Smart DOD use means you use less grid power and save more.

Cycle Life

Cycle life tells you how many times you can charge and use your battery before it wears out. If you use shallow discharges, your battery will last for more cycles. Deep discharges make the cycle life shorter. The table below shows what changes cycle life:

Capacity & Power Rating

You should check battery capacity and power rating when picking a solar battery. Battery capacity means how much electricity the battery can store when it is full. Power rating shows how much electricity the battery can give at one time. The table below explains these words:

• More battery capacity lets you run more things for longer when the power goes out.
• Higher battery capacity helps you save money by using stored energy when electricity costs more.
• Charging with solar panels and having enough battery capacity helps you save more.

Efficiency

Efficiency shows how much energy you get out compared to what you put in. Lithium-ion batteries are very efficient, usually between 90% and 95%. This means you lose very little energy when you store and use power. Lead-acid batteries are less efficient, so you lose more energy. Lithium Iron Phosphate batteries are safe, last long, and work well, especially in hot places like Arizona.

• High efficiency means you get more energy from your battery.
• Efficient batteries help you save money and use more solar power.

Tip: Knowing these words helps you pick the best solar battery for your home and reach your energy goals.
