A battery which can be charged is needed in a solar power system as the battery will be used to save energy to avoid interference and can deliver electricity when the sun is not enough or when a large electric power, which has been stored previously, are needed in a short time. Thus, when going to install a solar power system, you do not only need to choose the solar cells of the ways to install them such as to install them yourself or to hire click for more info, but also the battery to be used as storage of the power.

The battery capacity is measured in watt per hours. For example, a battery with 100 watt per hour can accommodate 5-watt charging for, at least, 20 hours or slightly longer due to power loss and release the power of 25 watts for four hours of use. Larger systems usually use a lot of battery installed in parallel. There are many types of batteries, with distinctly different characteristics. Thus, unlike solar panels, this is not only a matter of power per unit of size or price. The battery must be large enough to accommodate charging the full emotion of solar panels, and more if you want to miss a day without charging and still be able to use the equipment in full. Batteries should not be charged for too fast that you need to make sure that the battery is receiving an abundance of energy from the solar panels can receive maximum charging capacity.
The wet accumulator or a lead-acid battery is pretty cheap when viewed from the capacity and durability but it is not suitable for portable equipment because it is filled with acid. Some types also need to be filled with water from time to time.
You should not use batteries which are used in ordinary cars. Deep-cycle battery, which is normally used by the engine powering a motor boat or RV, is a type of battery that can be used for solar power because they are made to be able to discharge a recurring basis rather than one burst of power when starting the engine. A dry accumulator or gel cell is the lead-acid batteries which are sealed with acid wrapped in a material to reduce the danger that the battery is leaking. An accumulator is not expensive when viewed from its capacity, although more expensive than the usual wet battery. The accumulator is usually relatively heavier when compared to non-battery lead-acid.
That is a simple explanation about some of the types of batteries which can be used in a solar power system. Hopefully, the explanation can help you decide which type of battery that is more suitable for your solar power system.
