As new clean energy, solar energy is highly praised by environmentalists. Because solar energy can effectively save electricity, its popularity in American households is very high. Although solar energy has many advantages, there will always be unexpected conditions, such as continuous rainy days, emergency power failure, and so on, which make us into the plight of no electricity. Here, we need to introduce the concept of solar energy storage. We will walk you through the working principle of a solar battery in detail, step by step.
Solar battery
Let’s figure out what is a solar battery first. The solar battery is a kind of battery that stores energy from the solar photovoltaic system. When the power generated by solar panels absorbing solar energy exceeds the energy consumed by household appliances, solar batteries can play their role in storing the excess energy for backup in case of continuous rainstorm and emergency power failure.
Tiger Head solar battery can effectively save any cost by storing the electricity generated by solar panels, which is an essential step towards achieving energy independence.
Types of solar batteries
The lead-acid solar battery and lithium-ion solar battery are commonly used for energy storage on the market
In most cases, lithium-ion batteries are the best choice for home energy storage, although other types of batteries may be cheaper. That is because most of the home energy storage technologies use some form of lithium-ion chemistry. Lithium-ion solar battery is lighter and more compact than the lead-acid solar battery. Furthermore, compared with Lead-acid solar batteries, they have a longer service life and higher DOD (Depth of Discharge means the quantity of stored energy can actually be extracted from the device.)
Lead-acid batteries are a tested technology that has been used in off-grid energy systems for decades. Although their lifetime and DOD (depth of discharge) value are slightly inferior to lithium-ion solar batteries, they are still among the cheapest choices in the current market for home energy storage. Tiger Head solar battery is a kind of lead-acid battery, and it’s also the right choice for users who want to store energy for outdoor activities and small electronic devices.
How does a solar battery work
With a basic understanding of solar cells, you must be wondering how do solar batteries work?
The first step is to charge the solar battery. On sunny days, solar panels usually produce more electricity than a home need. When the available energy exceeds the required energy, the excess energy will flow into the solar battery to achieve charge. This will help offset the power from the solar photovoltaic system is unable to meet all the needs of the home (e.g., at night, and continuous rainstorm days).
The second step is to invert DC to AC, because the power generated by Tiger Head solar battery is DC, and household appliances generally use AC. If you need to provide power to household appliances or various electrical appliances, you need to install a DC / AC inverter. The inverter’s function is to invert the direct current generated by the lead-acid solar batteries into alternating current to supply power to the household or industrial use.
