Glad to hear that you are getting so sun down there Moxi, it's clear blue skies and -3C up here and the garage PV is giving 2.5kW but the larger caravan port system is doing nothing, it's got about 100mm of snow on it but at about an angle of 10 degrees it's going nowhere fast.Moxi wrote: ↑Wed Jan 17, 2024 11:34 am Better in North West Wales today,
420W going to the stack and the house load is balanced,
144Watts from the West 3.6kWp array and the rest from the 550Wp of panels I have lent against the south side gable of the cottage.
Theres a lot to be said for a well placed smaller panel when things aren't optimum for the main array.
Only 1 degree here still, I hope things warm up enough for the snow to sag and reveal some of the panel to clear them for you Fintray![]()

I could go up and brush it off but standing on a snow covered metal roof isn't the safest thing to do so I'll just wait till it melts which going by the forecast should start on Friday as it says it's going to be a tropical 4C.
Interesting question. How many kWhr of heat in the hose (or do you think mains water would be "warm" enough?) and how many kWhr of pv gain would result?
Cold water should do it, its ground source, another renewable resource.AE-NMidlands wrote: ↑Wed Jan 17, 2024 12:39 pmInteresting question. How many kWhr of heat in the hose (or do you think mains water would be "warm" enough?) and how many kWhr of pv gain would result?
Our water pressure isn't that great so would still have to stand on the roof to reach all of it, roof is 9x7.5m and 3.5m at high side, PV array is 10.24kWp which covers almost the entire roof less 300-400mm along the edges.Moxi wrote: ↑Wed Jan 17, 2024 12:50 pm That’s if it doesn’t blow off, we have 45mph gust forecast Friday,
That’s why I asked about the hose, thinking you could stand at ground level and just wet the snow down to slush and and water which would allow the panels to start generating and warming up a little.
Nearly Friday though so not much lost.
Cold tap water at mine is presently about 6 degrees, given that’s embedded from its travel through the ground to the house I would think any gained energy would be worth it. Of course if you mean embedded from processing potable water then the average for the industry is 0.044watts per liter, I don’t know Fintrays array size but I would say if it took 500 litres to wet off the snow and start the panels running then 22 watts.
