Why are batteries so expensive solar?

Batteries used for solar energy systems are typically more expensive than regular batteries, such as lead-acid or alkaline batteries, simply because of their complexity and the extra safety features they have.

Solar batteries are much more powerful than regular batteries, as they are designed for a much longer duration of service and must store more energy and thanks to advances in technology, they can now do this safely.

Solar batteries hold and store this excess electricity – generated from a solar array when the sun is shining – to be used when required either during the night or in cloudy weather. To store the large amount of electrical energy needed in a solar-powered home, a larger capacity, high-quality battery is needed, which will typically be more expensive than regular batteries.

In addition to the complexity and larger container requirements, the cost of solar batteries is also impacted by the higher quality components that are used in their construction. Solar batteries are commonly deep cycle batteries, meaning they can be deeply discharged and charged multiple times over an extended period of time – much higher than a regular lead-acid or alkaline battery can be discharged and recharged.

As a result, these batteries require stronger components and therefore, the cost of these batteries is higher.

Due to the complexity and additional safety features associated with solar batteries, they will always be relatively more expensive than regular batteries, but the long-term return on investment they offer in terms of reliable energy storage usually outweighs their upfront cost.

What is the main problem with solar cells?

The main problem with solar cells is their efficiency. Even though solar cells have become more efficient over the years, they still don’t reach the efficiency levels of traditional sources of energy, such as fossil fuels and nuclear power.
