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.
How many solar panels do I Need?
The number of solar panels you need depends on battery size, sunlight availability, and system efficiency. For a 12V 100Ah lithium battery, around 400W of solar panels is ideal. Larger systems like 24V, 48V, or 20kWh setups require proportionally more panels.
How much energy does a solar panel use?
Optimal ranges often depend on balancing energy use with available sunlight and panel efficiency. A unit of energy equivalent to one kilowatt (1,000 watts) of power used for one hour. Example: Using a 1,000-watt appliance for one hour consumes 1 kWh. The number of hours per day when sunlight is strong enough to produce maximum energy.
How much solar energy does a 12V 100Ah battery produce?
So, a 12V 100Ah lead-acid battery effectively provides only 600 Wh. The next factor is sunlight availability. Solar production is measured in peak sun hours, not the actual hours of daylight. 1 peak sun hour = 1,000 watts of solar energy per square meter. Example: In Houston, Texas, the lowest sun hours in winter is about 3.5 hours/day.
What is the core formula for solar panels & batteries?
The core formula considers several factors to determine the correct size of solar panels and batteries. It calculates the total energy requirement, divides it by the product of panel wattage and sunlight hours, and incorporates battery efficiency to suggest storage needs.
