How many solar batteries are needed to power a house?

Solar panels produce a ton of energy every single day. So, the first question that might be on your mind is, how many batteries do you need to power your entire home? How much power and how much energy can your solar system produce?

On average, a home in the USA will require around 19 to 23 solar panels to power the entire house. The electricity produced would be about 877 kWh in a month. The average cost will be from $13,000 to $16,200 if you opt for this system.

How do I choose a solar battery?

If you want your solar battery to give you maximum power, you should definitely look at its peak output. Let’s break it down. Peak output will tell you the measure of comparison of the energy provided by your solar batteries work.

In easy terms, the higher the kWp rating, the more power output there will be. Hence, the better the performance of the solar battery will be as it will have more depth of discharge. Therefore, make sure to invest in a battery with a very high peak output.

Which solar batteries last longest?

Of course, you would want to know which battery will run the longest in your home. This way, you will be able to have more cost per use of your purchase, and who doesn’t want that? On average, you will find 3 different types of batteries in everyday use:

  • Lithium-ion battery
  • Lead-acid battery
  • Saltwater battery

You will find that the first lithium battery will last you the longest from those mentioned above. Not only that, but these batteries will also have the best storage capacity on the market. However, the cost can be a bit too much to handle, so you need to keep that in mind for sure.
