If you've ever wanted to add solar to a flat roof without drilling any holes, this might be the simplest way to do it.
I've been meaning to install these two 200W Renogy solar panels (renogy.sjv.io/en5bkO) on the roof of my home office for a while now. There's the obvious benefit of the solar power they'll produce, but there's another advantage too, which I'll come back to later.
Rather than drilling into my felt roof—which, no matter how well it's done, is always going to compromise the waterproofing—I've gone for what I think is a far safer solution.
I'll also show you just how easy it is to make up your own MC4 cables and connect everything to a portable power station—my EcoFlow Delta 3 Max Plus that I reviewed recently—but this would work with pretty much any portable power station.
If you've already got a portable power station that's sitting around for emergencies or only comes out for camping, this is a great way to get much more use out of it. You can even have it acting as a UPS for your PC while charging from solar at the same time.
The whole installation took me less than half a day from start to finish.
