Solar Shed Lighting Calculator
Work out the specifications for a solar powered shed/garage/outhouse lighting system
In our article Shed and Garage Solar Lighting (1) we looked at how an efficient DIY solar lighting system can be put together using a PV solar panel (2), LED lighting (3), and a battery (4).
We receive many enquiries from people wanting to know what size of solar panel and battery they should use for a DIY solar lighting system, so we have put together this unique solar lighting system calculator which should act as an excellent starting point.
Assumptions made by Lighting CalculatorThis calculator assumes a 13VDC system - i.e. lighting powered by a well-charged 12V lead acid battery. It is also assumed that the solar panel will on average be exposed to 4 hours of good sunshine per day (UK average), and that the battery is never allowed to be discharged below 40% of capacity. For simplicity it is assumed that the system is 100% efficient - i.e. no battery self-discharge, all solar electricity gets into the battery, etc.
