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.

Leading Edge has a wide range of 12V DC solar panels suitable for 12V, 24V and 48V battery banks.  Choose from professional-grade monocrystalline glass modules with ultra-high efficiency SunPower cells for a range of industrial/commercial applications, and walkable marine solar panels from Solara.

If you include a wind turbine, you can generate even more power.  Take a look at our range of off-grid wind turbines, made here in the UK, choose one that will suit your power requirement or contact us for advice from one of our off-grid specialists.
