In the solar photovoltaic power generation system, there are 4 main types of solar batteries you can choose from. They are lead acid batteries, lithium-ion batteries, flow batteries, and nickel-cadmium batteries. Currently, lead-acid batteries are mainstream for solar battery storage.
Lithium-ion is the best type of battery for solar storage. The lithium battery has a longer cycle life, is safer to use, and is lighter in weight compared to lead-acid batteries with the same capacity. BougeRV 12V LiFePO4 battery is your best choice.
At 12 hours to fill up, you would need a 100-watt solar panel. If you want to fill up faster, you need to choose a larger solar panel. The size of the solar panel needed to charge a 12V battery depends on the capacity of the battery. Let's say if you have a 12V 100Ah solar battery, which is the most common battery used in solar power systems.
You can calculate by using these formulas:
Voltage (V) x Capacity (Ah) = Total wattage (Wh)
Solar panel size (W)= Total wattage (Wh) /Peak sun hours (H)
Generally, solar batteries have a service life of 5-15 years. The lifespan of solar batteries can be impacted by many factors, such as type of battery, installation, environment, depth of discharge, and maintenance. BougeRV 12V LiFePO4 battery utilizes high-quality LiFePO4 technology and has a lifespan of 10 years, with over 4000 recharge cycles and a 100% discharge rate.
The price of solar batteries varies with different capacities and product quality. It usually ranges from $300-700. You can buy a BougeRV 12V 1280Wh LifePO4 battery for $499.
You can charge your solar battery from a solar panel in 2 steps. First, you need to connect your solar battery to the charge controller, then connect your solar panel to the charge controller. That's it!
There are 4 main types of solar batteries, but lead-acid solar batteries and lithium solar batteries are the most common types. At present, the market is dominated by lead-acid solar batteries. Because of the advantages of lithium solar batteries, such as higher safety and longer service life, they will gradually channel lead-acid batteries.
Of course, solar batteries are worth it. Solar panels can only convert light energy into electricity, but they can not store electricity. By storing the electricity converted by solar panels, you can lower your electricity bill. If you're outdoors, they could be a key component of your energy system.
