truman Posted October 20, 2015 Share Posted October 20, 2015 Thanks, that is more helpful than the anti, anything to do with climate change spiel. But what I need to work out, is how much power they are producing per hour. So if I have the PC and radio on, is there still power left for the washer and kettle on a sunny and cloudy day. if you're only making 3 and a bit kilowatt hours a day then no there won't be..I don't think anyway...

Didn't the whole system come with some sort of spot metering? If you can't accurately measure how much the PC is using, then at best anything else is a guess. The kettle should be entirely predictable, and the radio might as well be ignored. The generation over 3 days is obviously only an average though, but basically the PC alone will have used all the power that your solar system generated I think. Going to just calc that and double check. ---------- Post added 20-10-2015 at 13:12 ---------- 9.7 in 3 days. Assuming 8 hours a day of generation, that's 0.4 kwh per hour. Your PC and monitor are probably drawing 350 watts, or 350wh/h, so pretty much using up all the power your system can provide. Link to comment Share on other sites More sharing options...

Cyclone Posted October 20, 2015 Share Posted October 20, 2015 4Kw is a theoretical maximum under perfect conditions. Link to comment Share on other sites More sharing options...
truman Posted October 20, 2015 Share Posted October 20, 2015 4Kw is a theoretical maximum under perfect conditions. I would have expected to get more than 9kwh over 3 days... that's only about 2 quid's worth of leccy..take a while to get any investment back...

unbeliever Posted October 20, 2015 Share Posted October 20, 2015 I dont need to store it, I have mains power too Heres an idea. Why don't you use the mains power to run some big electric lights? You can mount them on your roof and point them at the solar panels all day and night. That way you're guaranteed to be generating the full 4kW and you can probably save the planet single handed. ---------- Post added 20-10-2015 at 13:29 ---------- I would have expected to get more than 9kwh over 3 days... that's only about 2 quid's worth of leccy..take a while to get any investment back... To be honest, they'll probably pick up in summer. The sun never gets overhead at this time of year. Link to comment Share on other sites More sharing options...

Bird poo on them already, perhaps that is it I will have another look at the readout near the inverter, some electric will BE used straight away by myself, and some into the grid when I am out.

Cyclone Posted March 4, 2016 Share Posted March 4, 2016 What's the situation now El Cid? Link to comment Share on other sites More sharing options...
El Cid Posted March 7, 2016 Share Posted March 7, 2016 Not read the dial recently. EDF has confirmed that its finance director has quit ahead of an expected final investment decision on the £18bn Hinkley Point nuclear power plant. Thomas Piquemal stepped down because he feared the project could jeopardise EDF's financial position, according to reports. EDF shares opened 8.2% lower on Monday.

jamesey Posted October 30, 2016 Share Posted October 30, 2016 hi ive got a south west facing 12 panel 3.5kwh system fitted and it was wired into a samil 2 way iverter on 2 strings for all 12 panels , this lasted 3 years and blew the chip. i rang the company up that installed the system and samil uk said that it needed to be wired in 4 strings,,,,6 on 2 and another 6 on 2 so it worked right on the 2 way inverter . since my pv company have fitted this it doesnt seem to be makeing pv like it used to for example today the 30th of oct a full dull day its made a mear 0.56kwh all day , does this sound right? what has other peoples made today?
