A solar battery captures excess electricity from your solar panels and holds it for later use. Instead of sending surplus power back to the grid or losing it entirely, a battery lets you bank that energy and deploy it on your own schedule.
Enter a few required parameters into the following calculator and estimate the number of panels, solar array dimensions, and area required to install a solar system.
Solar System Calculator (SSC) - free, easy-to-use web tool to size solar panels, batteries and inverters for residential off-grid systems. Calculate load, inverter size, battery capacity and panel wattage in minutes.
Solar panel installations typically cost between $13,962 and $27,924 in 2026. The actual price tag depends on your home's energy needs, roof characteristics, local incentives and other factors, all of which we'll break down in this guide.
For most applications, a good rule of thumb is to aim for a 1:1 ratio of batteries and watts or slightly more if you live in regions with limited sunlight, such as near the poles.
In this post, we'll explore the differences between connecting solar panels and batteries in series and parallel, including the pros and cons of each connection type.

In 2025, standard residential solar panels produce between 390-500 watts of power, with high-efficiency models reaching 500+ watts. However, the actual energy output depends on multiple factors including your location, roof orientation, weather conditions, and system design.
