Hi everyone. I`m currently in the process of gathering quotes and contemplating putting in a 3.68/4kw system.
I`m seein the figures you guys are quoting (£6/£7 per day!), how big a system does that require?
Sorry for not looking back through the thread.....also, any advice would be greatly appreciated.

Note - I live in NE Scotland, and half a South facing roof at about a 35 degree angle

Cheers!

Weather's changed a bit today though

My signature describes my system, which has a record day performance of 23.8kWh (£11.53 on our tariff). However you should note that more recent installations only qualify for the more recent tariffs which are significantly lower, but on the flip side the installation cost has come down considerably.

I'd suggest you head over to the FAQ thread as a starting point, then perhaps start a new thread if you have specific questions. Some of the regulars will most likely chip in with their thoughts.

Hiya shavy, and welcome. I think SDJ's answered you, but 'just for a laugh', with today's tariff, a 35d pitch, south facing install in Aberdeen, would need to be approx 21kWp to (on average) earn £6/day in February.

If it's helpful, a 4kWp system (as above) would generate a surprisingly good 3,480kWh pa (guestimate from PVGIS, see FAQ section 5). That equates to approx £720 pa (FiT+export+£120 leccy savings (guess)).

All the best.

Mart.

Hi

I rarely post generation figures because, on the whole, it's meaningless.

If you want to get a better idea of how systems in your area (and the UK as a whole), have a look at PVOutput ( http://pvoutput.org/ ) ..... January 2014 for the UK is currently showing 0.769kWh/kWp per day (this may change as other readings are submitted), therefore a realistic average for UK 4kWp systems for last month would be 95.4kWh(0.769x4x31) which at post 01/04/14 FiT tariff rates would have returned £15.99 for the whole month (95.4x16.765p).

To place into context, our system marginally outperformed the UK average last month, we had good days and bad days. Today is yet another bad day, ~1.6kWh generated so far (14:40), but it's now hammering down with rain and the inverter's gone to sleep (0W) .... someone, somewhere will be fortunate enough to have seen a decent amount of bright sky and will probably be along later to gloat, even though yesterday's generation could have been abysmal ....

Overall, averages are averages and each system is different - so take more heed of them and the estimated figures from PVGIS ( http://re.jrc.ec.europa.eu/pvgis/apps4/pvest.php ) than some of the incredible figures you may see on these boards.

According to Martin's Weekly email, "Want solar panels? Now's the time" "The amount paid for generating electricity with solar panels will drop for those getting it from 1 April."

For those who haven’t already seen it, here is a link to the latest FiT table which takes account of the annual increase in RPI published for December 2013, 2.7%. For early adopters, the rate from 1 April 2014 will be 48.07p and the Export Tariff will be 3.39p, effectively giving a total of 49.765p per kWh generated.
