Solar-powered Batteries-Application, Cost, And Power Supply

Our energy resources are scarce and solar energy is a renewable source of energy which has created a lot of hope. It is gaining popularity day by day and is now one of the fastest-growing energy sources in the USA and other countries. It is now a billion-dollar market. Solar power technology has to lead to the use of solar batteries that can store solar power for use later on. Many companies like Tesla are now coming up with batteries that can be installed with solar panels for home use.?

Solar energy systems include solar panels, equipment for mounting the panels on the roof, an inverter, and a monitoring system to track the amount of electricity produced. The solar panels collect solar energy and convert it into electricity. It then passes the electricity through the inverter and is converted to a form that can be used for powering the home.

Solar batteries can store the energy that is produced by the solar panels for use later. The amount of solar energy the battery can store depends on the battery’s capacity. You can install the solar battery as part of the solar panel system to store the extra solar electricity. If more solar energy is produced than needed then the extra energy is used for charging the battery. Then when the solar panels are not producing any energy, for example, during nighttime, electricity that is previously stored in the battery is drawn down for use. In such a case you only need to send the electricity back to the grid when your battery is fully charged. Similarly, you need to draw electricity from the grid only when the battery is depleted. So, the pressure of the grid decreases when you have a solar battery. You can have short-term backup power always in case there is a power outage in your place.?

Should you install a solar battery at your home?

A solar battery is very useful for homeowners. It can store electricity for later use. It provides the homeowner flexibility in using electricity. When you use the photovoltaic system without a solar battery, the electricity that is produced must be used up immediately. So, at night you won’t have any electricity. Most households need electricity more during the night. If you have a solar battery then it can store the electricity for later use. The solar battery will provide energy even when there is no sun and the panels are not producing electricity.

Because of solar batteries, it is much convenient for the grid operators to manage the flow of solar electricity. You can optimize the self-consumption of the PV system’s energy. Solar batteries can reduce your electricity bills, depending on certain conditions. Most utilities at home provide full net metering, that is, you receive credit on the bill for each kilowatt-hour electricity of solar energy produced. So, on your monthly electricity bill, you won’t notice any savings. If the utility doesn’t offer net metering then solar batteries can save you on your electric bills. By using solar energy from solar-powered batteries you will be contributing to a sustainable future.

Solar Battery Storage System Cost

Now there are many manufacturers of solar batteries. The price of the battery depends on a number of factors like the capacity of the storage system, the components installed, and more. The electricity prices and installation costs vary from one place to another. Typically, the price of solar batteries ranges from $5,000 to $7,000 or more. Also, it costs $400 per kWh to $750 per kWh. This price excludes the cost of installation and equipment. If you consider all these extra costs then the cost of installing a solar battery will be approximately $11,000 to $18,000 or more and $800 per kWh to $1,300 kWh. The prices of the batteries vary depending on the materials it is made of and the amount of power it can provide. There are some financing options for buying solar batteries. You can buy or lease a solar battery. Many solar companies offer leases. There is the federal investment tax credit (ITC) incentive for the homeowners to install the solar battery. According to this scheme, the price of the solar battery is reduced by 30% for homeowners. The local government and utilities also provide extra incentives for use of solar batteries at home.?

Lithium-ion Solar Battery Bank

When it comes to buying a solar battery for home use you must consider buying a lead or lithium-ion battery. Lead-acid batteries are not much used today. Lithium-ion batteries are in demand now as it is safer and has a longer expected life than the lead-acid batteries. Also, the lithium-ion batteries can discharge up to 100% of the stored power, compared to only 50% discharged by the lead-ion batteries. The system efficiency of lithium-ion batteries is also more. Though the cost of a lithium-ion solar battery is more than the lead-acid batteries upfront, when you compare the cost per cycle over the life of your battery, the cost of the lithium-ion battery will be less. For everyday residential use, a lithium-ion battery is the best choice as it takes up less space and can store a huge amount of energy. The battery lasts longer, so you won’t have to replace it any sooner.?

When buying a lithium-ion battery for home use you must consider several factors. You should buy a battery that can supply solar energy for the entire house throughout the night. You should also consider the depth of discharge of the battery, which is the amount of the stored energy that can be withdrawn from the battery.?

It is a good decision to invest in a solar battery when you buy a new photovoltaic system. This way you can use a large chunk of solar power and reduce the amount of electricity purchase from an energy supplier. This will lower your electricity bills considerably. The best part is that you will be using renewable energy and contribute to a sustainable future.?
