Solar Energy Batteries-A Critical Review

Abstract

Solar power has numerous benefits, it is a clean and renewable energy resource that can help us to reduce carbon emissions from fossil fuel use and mitigate climate change. However, solar energy production is limited to daytime hours when sunlight is abundant, and for solving the intermittency problem batteries bank has been used, where it store electricity for later use, so you can keep appliances running during a power outage, and use more of the solar energy that you produce at your home. Solar batteries are a deep cycle batteries, as the current flows from the battery in small quantities and evenly. This article represents; difference between automotive batteries and a solar batteries, a brief explanation of the different types of solar batteries and a comparison between them in terms of price, depth of discharge , service life, charge and discharge temperature, and energy density. The article also introduces an electrical representation of the battery, criteria that are taken into account when choosing the appropriate battery such as battery capacity, battery efficiency, depth of discharge of the battery, the time required for charging the batteries, and connect batteries in series and in parallel, where it is necessary to know this information to choose the appropriate battery for designing the solar systems.
