    Ultima solar PV hybrid 3.84kW predicted 5333kWhpa output

    Hi, Has anyone come across the Ultima solar hybrid panels? I have just come across a quote stating that a 3.84kW system will likely have an annual output of 5,333kWh per annum. This seems a bit optimistic, but I am not familiar with the technology and wondered if anyone here is? cheers Matt

    How many kW have you installed in Feb?

    Well... Jan was really a slow start, but ever since the announcement on 9th Feb, it has gone a little crazy. How many kW's have you guys managed to install or get booked in before the 3rd of March?

    PV Panel War: Sanyo v. Hengji. The ultimate side-by-side long-term, real-world test.

    Panel efficiency: Why does it matter?

    I’ve been comparing various makes and models of PV panels for an 8kW project. Sales people keep on and on at me about this or that panel being ‘more efficient’ than some other, so is obviously worth the extra cost. My understanding is that the efficiency of a panel is the rate at which it...

    Fixing Sanyo N240 panels in landscape

    I read somewhere that when mounting in a landscape format, most panel manufacturers do not recommend that their panels are clamped on the short side. Is this case with the Sanyo N240 model and if so do Sanyo recommend using vertical rails? John

    Small PV panels (physical dimensions)

    Hi All Due to space issues, i need small panels on my roof to maximise kWP. The Sanyo N235 and N240 are obvious candidates due to their relatively small sizings but reasonable peak output.

    I am being offered Sanyo HIT panels at a fair hike in cost, but supposedly they are much more efficient (and also happen to fit my awkward roof quite well). Has anyone used these, and how much better is generation vs monocrystalline?
