A solar battery stores the energy produced by a solar PV system. The system's panels collect solar energy and convert it to power, which is then routed through an inverter and consumed by your home. A battery is an optional component that allows you to store energy created by your panels and use it later, such as at night when your panels are no longer producing power. Your solar PV system is connected to the power grid unless you have an off-grid installation, which allows your home to continue getting electricity even if your panels aren't producing enough energy to meet your demands. When the output of your system exceeds your energy use, the excess energy is transferred back to the grid, a procedure known as "net-metering." When this happens, you will receive a credit on your next electricity bill, which will reduce your payment amount.
Solar batteries, on the other hand, may be an enormous addition to a solar PV system for people who live off-grid or choose to store extra energy rather than send it back to the grid.
As previously stated, surplus energy from your solar PV system is stored in the battery. This implies that excess energy may be stored and used whenever your solar panels are not producing enough electricity.
• Battery life and warranty
• Power capacity
• Depth of discharge (DoD)
A battery's lifespan is typically between five and fifteen years. However, this is predicted to expand dramatically over time to keep up with the proliferation of solar panels. Battery warranties are often expressed in years or cycles; for example, the sonnenBatterie has a guarantee of 10 years or 10,000 cycles (whichever comes first). The entire quantity of electricity that the battery can store is called its power capacity. Solar batteries are often stackable, so you may have additional battery storage units at home to boost capacity.
The DoD assesses the extent to which a battery may be utilized at about its total capacity. If a battery has a 100% DoD, it signifies that you may use the whole battery storage capacity (e.g., 2.5kWh) to power your home. If a battery has a DoD of 94 percent, that indicates you may utilize up to 94 percent of its capacity (e.g., for a 2.5kWh battery, you can use down to 2.35kWh before the battery needs to charge again).
A solar battery is not always appropriate for all solar PV systems. To begin, you must ensure that your system is compatible with having a battery added to it. Assume you want to add a battery to reduce your electricity bills further. In that case, you must ensure that your system produces enough excess energy to charge the battery once it has delivered the ongoing daily energy demand to your home. If not, you may need to increase your solar PV capacity to generate the necessary surplus electricity. Several solar battery wholesalers produce safe and durable batteries at affordable prices for their customers.
