The Ultimate Off Grid Watt Hour Calculator - Figure out how much solar you need.

The first step in figuring out how many solar panels you need and what size of off-grid solar system will work for you, is to know how much energy you use on a daily basis.  No matter how big or how small, the first step is always calculating how many watts per day you will need. 

We created this off-grid calculator in order to help you quickly and easily add up all of your daily energy consumption and get this total in watts.

If you scroll below the calculator (on this page) we've outlined how many watts all of the most common appliances use so all you need to figure out/decide on, is how many hours per day you will be using each appliance.   

Also, we generally advise against adding any appliances that can be propane-fuelled, such as cooktops, hot water heaters and electric heat as these won't require any of the solar power we're harnessing.

If you'd like to know the EXACT watts of the specific appliance you're going to be using, you can usually find this on the back of most appliances, under their "energy use information".
