Solar Batteries
Storage batteries are one of the most essential parts of a solar energy system. There are different types which serve various functions to make the solar energy system better. Because of this, their price is also considerable.
Do I Need Batteries For My Solar Energy System To Work?

A lot of people consider buying batteries alongside their solar energy systems. Batteries are sold separately from solar energy systems. The cost of the backup batteries has fallen over the past few years. They are becoming one of the primary components of solar power systems.
The price of solar batteries falls within a range of $7,000 – $15,000. Although most people find the option of running home appliances independently appealing, the truth is that solar batteries are not strong enough to run your entire house. They can only power a limited number of devices, and that too for only a day.

Selling Solar Batteries
- saving money by using less energy from grid-tied systems
- contributing to environmental protection by not using coal-power generators
- achieving independence in use and distribution of electricity.
The prices of batteries are likely going to drop further in coming years. This may lead to electrical companies offering a more significant amount for their electricity reserves to smooth out grid-tie fluctuations.
Which Type of Battery Is Best For Active Solar Use And Why?

- Lithium Iron
- Nickel Iron
- Lead Acid.
The Pricing
For long-term planning, Nickel-iron batteries are the most suitable, as they cost the least. However, you will have to maintain these types of batteries with regular inspection and monitoring.
Lithium-iron is also a viable option. Although it is slightly higher in price than Nickel-iron, its long term savings are as good. More importantly, there is no maintenance required at all.
Performance and Life Cycle
If we study a comparison chart of the three types of batteries, we find that Lithium Iron tends to perform the worst. It has a low life cycle coupled with a low depth charge of around 50%. Even worse, the battery bank requires regular replacement, which will drain even more money. Nickel iron batteries have a much longer lifespan of around 30 years. The depth discharge, however, is the same.
