Geeky question about solar yield data...
Hi all, We've had our 4.35 kWp solar PV installed since the end of March and I'm trying to work out how we are doing in terms of meeting our yield projections. Just a bit of fun really, I know the future weather is a bit of an unknown. :) I found some historic data from someone local with a similar install to mine and it…

Help me troubleshoot why I have no hot water with an iBoost
Hi all As the title says, I have no hot water. Since our panels were put in with an iBoost in March we have had toasty hot water all day. I put the hot water to come on by timer, as recommended by the installer, for about an hour or so in the evening just to ensure the tank is nice and hot for the following morning when my…

Personal tradeable carbon credits?
So their was a recent suggestion that frequent flyers should pay an extra carbon tax which got me thinking. Why don't we work out a national carbon budget and then share it equally between everyone including children. Then out of our budgets we could 'buy' our carbon needs for utilities, transport and international travel.…

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…

From crisp packets to contact lenses, there are (literally) tons of items we still throw in the rubbish bin. Read the full blog: Free way to recycle…
