Email Probably the most asked question people have when it comes to solar energy systems is: “How many solar batteries do I need to run my house.” Truthfully, this depends on a number of factors: energy usage, the size of the solar panel system, the capacity of the batteries, and how long you want to store energy. In this article, we take a closer look at how to determine the number of batteries that will be required, how solar batteries work, and further benefits derived from using them. We’ll also be discussing the FranklinWH: the leading energy storage solution to upgrade your solar power system. What Are Solar Batteries? Solar batteries are such a system that saves the extra energy produced by your solar panels. Because your solar panels would only produce energy when the sun is out, it gives a leeway for storing that energy for cloudy days, nighttime, or other power outages. Without batteries, one would have to depend on the grid for this power when the solar panels cannot create enough electricity. How Solar Batteries Work? Basically, solar batteries store energy in chemical forms. During the day, when the solar panels are producing more electricity than what the house is using, the excess energy goes to the battery. The battery will then send this energy for later usage. At night, or during periods of low sunlight, the stored energy is drawn from the battery into powering the home. Factors That Determine How Many Solar Batteries You Need Here is a step-by-step process to enable you to estimate how many solar batteries you need to run your house: Daily Energy Usage The first and foremost step in calculating how many solar batteries one is likely to require for the establishment of a home is an understanding of the daily energy usage of a particular household. On average, a single day in most homes in America uses around 30 kWh of electricity. This amount, however, greatly varies depending on: The number of individuals dwelling within the house The size of the house Energy-efficient appliances
