We have put together a small collection of useful calculators to help you design your off-grid power system, be it solar, wind or both!

Please bear in mind that when estimating solar power production we always err of the side of caution. As a result, our figures and calculations are quite conservative; always better to over-perform than to disappoint. 

The cable size will vary from one wind turbine to the next and on transmission distance so please consult the installation manual for the turbine in question.
