What has YOUR solar PV system generated THIS month?

dangermat

On PVOutput you can compare your system to other peoples. This is done by comparing the efficiency of the array (generation divided by system size) rather than the total daily/monthly generation.

Hmmm, not to sure what my parents have had popped on the roof = all i know is its an 18 panel install done by a shade greener..

so, free install but they take the FIT and parents get free power whilst generating.

but in the 3-4 days it's been up on their roof it's reported 18,18 and 17 kWh's for sat, sun and today which have all been nice sunny days.

Hopefully they will see a nice reduction in their bills....

My 18 panel installation uses 180W panels which gives me 3.24kW, most of the free installations seem to around that level.

I have been getting 27 to 29 units so far on the last few sunny days and we did a total of 3600 units in the year last year which gave us a saving of around £270 on our actual bill for the year. But the government gave me just over £1650. That goes up each year though with inflation my electric company predicts it at £1750. Happy days.

Well once again a great month!
Produced 614.5 kWh in May.
Yearly estimated production is 4.200 kWh.
Detailed view can be found here: mypowerunit 3.600kW
And June is performing great until now above 30 kWh/day.
Wishing all a great and sunny summer

Wow that's brilliant for a 3.6 kwh system, mine is a 3.84 kwh and the orientation could not be more perfect. Your panels must be the really efficient Sanyo ones are they? What did you pay for them mate?

simmayor

Its Bosch panels and a Fronius inverter. I was told when I ordered the system, the the real output would be better than the theoretical and it might be true.
The price Dkr 75.500,  which is around GB£ 8.600. Which makes a payback time at approximate 9 years. Which makes it a proper investment in my opinion.

hi,

I have just found this thread, and have a big newbie qn to ask...
I have just (3 months ago) moved into a house with solar panels on the roof. They are not owned by me but i understand i get money off my bills when it produces electricity.
How do i find out what my panels are producing each day? This would clearly be for my info only as im not getting the FIT...
cheers in advance...

Is it a rented place? There should be a seperate meter for the panels, usually next to the electric meter but I suppose not necessarily.

Kevin OConnor

Its not rented, I bought in in August... however was very suprised when I recieved zero paperwork from my solicitor upon completion that would answer some of these questions. There is a meter in the loft that i took a photo of today, the reading said 5696.7 kwh with the letters CUM below which i assume to mean cummulative. What timescale would this be? a month/year.
