    Home solar panels are they worth it ?

    I've had a small amount of spare time the last couple of evenings so had a quick look at whats available in the way of PV panels for the home. From the limited information I can get without numerous companies contacting me to sell me solar panels it looks like they aren't really worth the bother...

    Solar isolator (to distribution board)

    I don't do PV, so not overly familiar with specific regulations. Yesterday I was changing a consumer unit, and the isolator for the PV was adjacent to the consumer unit. Due to needing a bit more space, I had to move this isolator a few cm and noticed it was single pole, switching L only. A...

    Solar iboost not working

    We have a solar iboost which was working fine then suddenly stopped. If you turn it off at the mains and then on again, it says low voltage and heats via solar initially with a high reading then this drops until zero and it states heating off. Amy ideas on what the problem could be? Thanks

    How does one HALF CUT solar module affect the other modules in the string when it is partially shaded?

    Hello everyone, I have a fairly technical question. I wonder what will happen to the efficiency of the PV system when we shade the bottom of one solar module (HCC) connected in series? Will the performance of the entire string decrease by half because only the top works in this module? Isn't it...

    Solar So called “new kind of battery”

    Got a advert through the door, obviously targeted, as I have panels on my roof.

    Need help converting solar light to wired DC

    I purchased some solar flicker flame outdoor tiki lights which I really like. The downside to them being solar is that each light does not get equal amounts of sun in my back yard so the length of time they remain on and their brightness can vary somewhat. Also, they have a photosensor and turn...
