Power output calculator
Calculates the minimum cable size needed for a specific length to avoid voltage losses. Enter the voltage running through the cable (V), the current running through the cable (A), the total length of cable needed (m) and also the maximum permissible percentage voltage loss (%V), typically 2.5%, then hit 'calculate'. Results are shown in mm2 cross-sectional area.
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.
