Solar Generator Comparison Calculator

solar system comparison calculator

This calculator will compare up to two solar generator systems by calculating how long you can run appliances WITHOUT SUN, as well as calculating recharge times, efficiency and more.

There are three steps to this calculator.

1- Choose up to two systems to compare.

2- Enter all appliances and tools you will be running in an emergency situation. Usually this means critical things, like a fridge or freezer, or maybe even a gas furnace.

3- Click the “Calculate!” button to calculate the results for the systems.
