Solar Battery Prices, Technology, Types- Everything You Need To Know

by Amit Sharma Digital Markter

With the rising consciousness about global warming and our individual carbon footprints, solar energy is emerging as one of the most popular sources of clean electricity. Harnessing this energy is simple as long as you have solar panels installed on your rooftop and have them connected to an inverter and battery. The battery is where power is saved and hence a non-negotiable element of the system. This is need for all types of solar power systems including hybrid and off-grid solar power systems. If you’re considering turning to solar power, here’s everything you need to know about solar battery cost, technology, types, etc.

Types of solar batteries

Solar batteries can be categorized a tubular batteries and lithium-ion batteries. The type of battery you choose will play a large role in determining the solar battery price. Tubular batteries have a higher efficiency, a longer lifespan and are easier to maintain. They require minimal maintenance and are more cost-effective. In terms of maintenance, they may need to be topped up with distil water every 3 to 6 months. Tubular batteries for solar power are usually taller than other tubular batteries. On the other hand, lithium-ion batteries are a little more expensive but have a lifespan of 15-20 years and maintenance-free. These batteries lose less energy when they are idling and hence may be used for small or large solar power systems.

Calculating Battery Capacity Needed

As the battery capacity increases, so does the price. Thus, opting for the cheapest battery may mean that you get a battery that does not meet your power needs. On the other hand, choosing the most expensive battery may make you spend more money than needed. To choose a battery, you must first understand your power requirements and the length of time you need backup for. Solar batteries are typically available in a 12 volt standard. A 1 kW solar power system needs to be connected to 2 such batteries. Similarly, a 2kW solar system needs to be connected to 4 batteries and so on.

Branded vs Unbranded

When you’re looking for batteries, always invest in batteries from well-known brands. Unbranded, local batteries may be cheaper but this is usually because they use substandard materials and come with no guarantee or warrantee. Once you buy the battery, you will get no installation or after-sales service. On the other hand, branded batteries offer an extensive warranty on the product and help with all your installation needs. Branded batteries also last longer and are more efficient.

Investing in a solar power system doesn’t just help you reduce your carbon footprint, it helps you save money too. Homes with their own solar panels, inverters and batteries have negligible monthly electricity bills. Instead, you get to have all your appliances working at all times irrespective of the power being distributed from the main power grid. In short, in exchange for paying the solar battery price, you can actually save money without compromising on your lifestyle.
