Output from solar panels on dull days??

[MJDW]

Hi All,
Just had a 3.84 kWp system installed. 16 Suntech 240w panels and a Eltec Vakere 3.8 HET invertor. System has been running for one week and it has been dull during this period. Any ideas on what kind on power should it have developed in this time? Actual is only 10.2 kW!!!
This seems low to me.

Thoughts?

Thanks​

10.2 kw is good.

Stop worrying and wait for summer.

MorganPVI is right, you have a PV system on your roof not a power station.
Over a 12 month period it will be fine.
Hope this helps

Check out pvoutput.org; and do a search** for other systems in your area. This will give you a good idea of the kind of output expected.
(**type in first part of your postcode and a range, for example: SU12 30km)

My system (4kw, south facing, S.England) produced 18.6kWh from Sun up to yesterday.

Hi - our 3.43 system has been running for 10 days and has only produced 12.6 - so don't worry.


Unless mine is no good also

How do you work that out then??
10.2 x .443p = £4.42 that's just for generation.

Mine's been in since last Friday and it's done 22kWh so far. 16 x Sanyo 235 SolarEdge installation, 10 south, 3 east and 3 west. I have another that's been in for the same period 12 * Sanyo 235 SolarEdge all south and that's done the same.

Both systems are suffering from shading from the scaffold still. It's amazing how a small pole can kill the output of a panel.

will its output be affected when it get dusty and dirty ?

Hi all , i have had my installation finished 2 weeks ago today , and have produced in total , 58kw in operating time 122 hours . But i am little mythed why it has not peaked at all , only ever got to 2.2kw and thats today on a really sunny bright day . my system is as follows
16 sanyo hit 250
power one 3.6 invert
south facing 30 decrees angle .
can any one tell me why its not peaked when the lux level has been well over 1000w m2 . maybe just worrying like us all on here for the amount we have paid for the system ..
