Wind being curtailed tonight
85% non fossil as we speak 3.5GW gas in the system yet wind being curtailed. I guess the grid needs those thermal plants to provide ancillary services like frequency control. Arguably 2.6 GW of French nuclear imports also being curtailed, interconntors like wind farms typically don't offer the same as thermal coal or gas…

Are our attempts to reduce CO2 emissions making things worse?
For years, I keep hearing that we should be reducing use of gas, cars etc to help the environment. So, we get an influx of solar panel companies, electric vehicles and hybrid vehicles etc. Then I read the other day on BBC News about the "Dirty Secret" that is increasing warming. It says that Sulphur hexafluoride (SF6) that…

Viability of hydroelectricity
We have a pond (about a quarter of an acre in size) that gets fed from numerous small streams and subterraneous sources, and the water feed is decent from autumn to spring especially when we get lots of rain. At the bottom of the pond, there is an overflow that has been concreted and this allow excess water to spill over…

Replacement inverter needed - is this a good quote?
In 2011 I had a 9.4kW ground-mounted system installed consisting of 38 panels with two inverters each of which takes power from 19 panels in two strings. Recently I noticed that the output from one of the inverters was roughly half of the other one, and a local installer (not the original one who has gone out of business)…

Electricity Standing Charges
This is possibly a bit tangential to most discussions on solar PVs but since i got my solar OVs plus battery at the beginning of March my electricity standing charge has been greater than the cost of my electricity. I'm with Bulb and my standing charge is 20.44p per day whilst my electricity costs 13.5p per kWh (24 hrs)…

E.ON Smart Meter Query
So I've now got my battery (I'll write about my experiences sometime soon) and was looking for a new tariff for my new levels of expected Electricity useage. I've found the tariff of my dreams as it has a low daily charge but only after signing up have found that I have to agree to a Smart Meter if they can fit one. Now…

Faulty Inverter or Panels?

3 years ago I installed Solar Panels after lots of support from this forum
Background 6.72kw system fitted producing approx 7.5mw per year. Really pleased absolutely no issues whatsoever. For months I considered a battery to soak up excess production but I believe economics still way off. Next chapter in my journey is that I have just bought an electric BMW I3s and I estimate a significant saving…
