Balcony solar PV

[Fintray]

I love that, his wee 2 panel system is kicking the arse of my 30+ snowbound & shaded behemoth.

Same here, 10.24kWp doing nothing.

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

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.

Don’t suppose your hose pipe will reach part of the panels will it ?

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.

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.

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.

Thats a shame, we have 6 bar here at the tap so we are more than a bit spoilt - although it does generate some water hammer when the washing machine solenoid valve operates so a bit of a double edged sword.

Wife has put the washing machine on here now too so the batter charge rate has taken a bit of a hit - cant stand in the way of cleanliness though, well not without getting a thick ear
