Title: June 2018 PV Generation
Post by: Wickham on July 01, 2018, 06:24:18 AM
June 2018

301.7 kWh total
113.42 kWh/kWp
3.78 kWh/kWp/day
10.06 kWh/day

2018 113.42 kWh/kWp
2017 102.11
2016 82.34
2015 117.76
2014 120.76
2013 103.32
2012 84.64
2011 102.43

Good but I expected it to be the best as we've had such good weather.

Hi
277 kWh
140 kWh / kWp


First full month with Powervault. and these are very rough approximations.

My daily use of power is approx 8 kWh / Day
With Solar PV my import is reduced to approx 5 kWh / Day
With Solar PV and Powervault the Import is approx 1.2 kWh / Day

Grid-assist battery storage

68.43 kWh harvested power
( = 61.6 kWh usable power after battery round trip)

Recent (5-yr-old) batteries will soon replace current 'mish-mash' giving 400Ah storage, so Ill be able to store/use more of the generated power.

According to a British Gas Energy monitor (freebie so accuracy doubtful!)  in the last 30 days 129 kWh has been sent to immersions!
129 kWh = 25% of the 520 kWh Generated so 75% not sent to immersions ( Exported!)  I know not really.

Just had Fit readings rejected as thye were higher than expected and outside of seasonal allowances!  So need to send them a photo! Happened this time last year as well!

Good Evening All,

Back from a weekend kayaking (badly) on the River Tummel. I've had to 'modify' the end of month figures.

June saw 478.2kWhr from the 4kW system and a further 127.8kWhr from the extra 1.675kW.

Regards

Richard
