You need around a 278Ah battery at 24V. You don't need to be a spreadsheet wizard to figure out your solar battery needs. There are online calculators that do the heavy lifting. Try tools like the Renogy Solar Calculator or EasySolar, where you just plug in your daily energy use, sunlight hours, and system voltage.
A Solar Panel and Battery Sizing Calculator is an invaluable tool designed to help you determine the optimal size of solar panels and batteries required to meet your energy needs. By inputting specific details about your energy consumption, this calculator provides tailored insights into the solar setup that will best suit your requirements.
Result: You'll need at least 5 × 400W panels to fully charge a 10 kWh battery on a typical Texas day. But hold on—this is just the baseline. Keep reading for the real-world factors that change this number. "Peak sun hours" don't mean how long the sun is visible in the sky.
The capacity of a solar panel to generate power under standard conditions. Example: A 300-watt panel can produce 300 watts of power per hour under optimal sunlight. The amount of energy a battery can store and supply. Example: A battery with 10 kWh capacity can power a 1 kW device for 10 hours.
