Portable (Folding) Solar Panels – what to look for Solar Panels are great – they allow us to put charge back into our batteries no matter where we happen to go. No doubt you’ve also realised that with panels there’s a major choice to be made – put them on the roof or have them […]

How much Solar do I need?


Posted by alistair on 17 Feb 2017 / 14 Comments
