Solar PV System and Solar batteries have gained prevalence over the years. It has turned out to be one of the most favourable sources of renewable energy in the recent times of energy crisis and high electricity prices.There are various battery brands and sizes available in the market. However, comparing and selecting the right battery options for your household or commercial is not an easy task. We make it easy for you! Keep reading to learn more about the battery size and solar battery brand options.
Lithium ion batteries
Lithium ion batteries are popular as they are the best compatible with a solar PV system. Lithium ion is used in lithium ion batteries to store the energy. The electrolyte is typically composed of a lithium salt solution, with carbon as the anode and any metal oxide as the cathode. Li-ion produces power as it passes from the anode connection to the cathode connection by converting chemical energy to electrical energy. Rechargeable batteries of the lithium ion variety are widely accepted in the telecommunications sector. The advantages that make these batteries best for use with Solar are:
- Light weight
- Low maintenance
- Lower battery discharge cycles
Modern lithium battery systems have swiftly replaced conventional lead-acid batteries over the years.
Correctly sizing the solar PV system and solar battery
The importance of getting just the right and correct size for your solar system and solar battery is not known to many. To keep the performance and efficiency up to the mark, it is necessary to find the right size solar battery option. When it comes to solar PV systems, getting a slightly bigger system than needed is advised. However, that is not the case with solar batteries. The factors that determine the size of solar PV battery are:
- Size of existing or new solar system
- Consumption pattern (night and day time electricity usage)
- On grid or off grid system
Solar battery size for your property can be best determined by a solar expert who can assess your bills and electricity patterns. Most modern battery options are technologically advanced and easily get connected to the solar system.
