Solar energy is a clean and renewable energy source of electricity with the potential to fulfill the world’s energy requirements. Due to this reason, many homeowners around the world are adopting solar power as the go-to source of energy.
Solar panels are a very common choice for home energy storage. Solar energy batteries, on the other hand, are not. The reason is the first thing people consider when buying solar energy batteries is the cost.
Are solar energy batteries worth the cost? Today, in this article, we will mainly discuss the types and benefits of solar energy batteries to find out the answer.
What are solar energy batteries?
Solar panels are essentially built to convert light energy from the sun into electrical energy. As most people use a small amount of energy in a day, solar panels usually produce more energy than the demand of their homes. Under this circumstance, there would be a need for an energy storage system. Solar energy batteries are extra storage units to store surplus energy.
How much do solar energy batteries cost?
There is no concrete price for solar batteries as the latest technology for energy batteries changes every day.
According to solar reviews, the cost of installation for a solar energy battery can be anywhere from 200 USD to 15,000 USD, depending on the battery’s capacity and chemistry. The average cost of solar energy batteries has also significantly decreased over the past years.
Types of solar energy batteries
Different type of solar battery uses different technology to recharge and discharge, and offer different lifetimes and efficiency. The main four types of solar batteries used for residential solar systems are listed below:
- Lead Acid Batteries
Lead-acid batteries are the most popular and used batteries worldwide due to their excellent life cycle and efficiency.
The lead-acid batteries generate electricity by the double sulfate reaching. The chemical reaction of lead-acid batteries is fully reversible. As a result, we can easily recharge and discharge electricity without losing any considerable energy between the cycles.
- Lithium-ion batteries
Lithium-ion batteries are the new and improved version of previous generations of batteries with the potential to be the next biggest energy storage solution.
The lithium-ion batteries utilize the same discharge and recharge cycle as the lead-acid batteries. However, lithium-ion batteries have a significantly higher energy density. The feature means lithium-ion technology can hold more energy in a significantly smaller-sized battery.
Lithium-ion batteries also have a longer lifespan. Although the cost is more expensive than the other solution, most lithium-ion batteries come with at least 5 to 10 years of lifetime. You can check for our home energy storage solution according to your needs at nRuiT.
- Nickel cadmium batteries
Nickel-cadmium batteries use cadmium as the electrode and the inorganic solid NiO(OH) (Nickel oxide hydroxide) to transfer ions.
The biggest advantage of Ni-Cd batteries is that they can work in fairly low temperatures and deliver rated capacity even at maximum discharge rates. Ni-Cd batteries also need little to no management systems and maintenance for the operation. For this feature, solar energy system uses Nickel-cadmium batteries in locations where extreme temperatures are the norm.
On the other hand, cadmium is a highly toxic material. So regular household use of nickel-cadmium batters is rare nowadays.
- Flow batteries
Flow batteries are the latest technology in the energy batteries industry. This technology uses two dissolved chemical components pumped through a system. Flow batteries offer significantly low degradation, making them perfect for long-duration energy output. The energy storage capacity of flow batteries can be increased by simply increasing the number of electrolytes in the tanks.
Due to the bulky configuration and high initial cost for production, flow batteries are still not popularly adopted in the household scene.
Benefits that solar energy batteries bring to the table
If you are thinking about whether or not to invest in solar energy batteries for home energy storage, these benefits below will help you decide.
- Energy security
Solar energy batteries for solar power systems offer you more security and less dependency on the grid of additional power demand. In case you live in a place where occasional power-outs are happening for poor grid management, the storage system will let you be in control of your energy.
- A quiet energy solution
In a power outage, one of the frustrating things to deal with is the generator noise. According to research done by All-Time Power, generators can produce anywhere from 60dB to 70 dB even when you are 7 meters away from the energy source. Solar batteries are completely silent and offer you instant power without any form of noise population.
- Better for the environment
A major part of the electricity generated throughout the world uses fossil fuel as the main energy source. One of the biggest reasons behind global warming pollution is the burning of oil, coal, and gas. Solar energy batteries are a completely clean and environmentally friendly solution to power storage.
- Less electricity bill
One of the biggest benefits of solar energy batteries is the energy storage system. Back up your home with a battery system to avoid the fees associated with electricity retailers, create self-sufficiency, and save the electricity generated.
