Battery Storage Solutions
More and more Texans are realizing the benefit of backup battery storage in their home to go with their clean energy solar system. Battery storage allows homeowners to be independent of the grid in case of a grid failure and keep the lights on when the rest of the neighborhood is dark.
Battery storage also helps homeowners maximize the power they are getting from solar by sending as little as possible back to the utility grid and staying as independent as possible. While solar is still primarily a grid-tied solution, the battery backup allows Texans to have as little dependence on the utility grid as possible.
We only use top name brand Battery Manufactures to ensure our customers are getting the reliability and quality that they have come to expect. If you have an existing solar system and want to add a battery that is no problem! We have custom options to add batteries to existing systems as well as build them into a new solar package. Give us a call today to find out what options work best for you!
How Do Solar Batteries Work?
Once solar panels have come into contact with sunlight, they convert the sunlight into direct current (DC) electricity. The electric current generated by solar panels goes to a charge controller, which regulates the charging process to prevent overcharging of the batteries.
The DC electricity from the charge controller is then stored in batteries. Solar batteries are typically deep-cycle batteries designed to handle repeated charging and discharging cycles. They store the excess energy produced during the day for use at night or when energy demand exceeds solar generation.
When electricity is needed, the DC electricity stored in the batteries is converted into alternating current (AC) electricity by an inverter. This AC electricity is then used to power homes or businesses. Whenever solar panels are not producing enough electricity, your system can draw power from the batteries.

The Types of Solar Batteries
There are two common types of solar battery storage: lithium-ion and lead acid. Lithium-ion is the most popular since it can store more energy, hold energy much longer, and has a higher Depth Of Discharge (DOD). DOD refers to a solar panel battery’s discharge capacity based on its total capacity. For instance, a battery with a 95% DOD can safely discharge 95% of its stored energy before its recharge.
Lithium-Ion Solar Panel Battery
Lithium-ion batteries rely on a chemical reaction that stores the energy as chemical energy, which is later converted into electrical energy. This reaction occurs after lithium ions release free electrons, which flow from the anode to the cathode. Lithium-salt electrolytes enhance this movement by providing the required positive ions, balancing the reaction, and providing enough free electron flow to create enough current for electricity use.
Lead-Acid Solar Cell Battery
Lead-acid solar battery storage is a rechargeable battery that relies on lead and sulfuric acid. The lead submerged in the sulfuric acid allows a controlled chemical reaction to produce electricity. This technology is popular in car batteries.
What to Look For When Purchasing Solar Batteries
Purchasing solar batteries is a significant investment that requires careful consideration to ensure you pick options that meet your energy needs. Here’s a breakdown of some of the crucial factors to consider when purchasing your solar battery storage:
Capacity
Determine the energy storage capacity (measured in kilowatt-hours, kWh) and power rating (measured in kilowatts, kW) required for your energy needs. Consider factors such as daily energy consumption, peak power demands, and desired backup duration during periods of low solar production.
Battery Charging Time
The best solar cell batteries, such as lithium-ion batteries, take less time to charge. Therefore, evaluate the options available to find one that will take less time to charge and more time to discharge.
Efficiency and Charging Characteristics
Look for batteries with high charge/discharge efficiency to minimize energy losses. Consider charging characteristics such as charge acceptance rates, charging voltage requirements, and compatibility with solar charge controllers and inverters.
Warranty
The best way to determine whether a solar panel battery is reliable is to examine its manufacturer’s warranty. High-quality options offer better terms in their warranties, expressing their manufacturer’s confidence in their products.
