Expanding a 4kW PV Only System
Given the advent of Flux, I've decided to take advantage of the Barclays Green Home Reward and expand upon our 4kW LG Bifacial PV system (roof pictured below). Leaving 100cm for Velux windows at the very North of the roof, it would appear that we may have space for 4-6 additional panels on East & West aspects, making this…

Solar PV "Power failure"? Technicians in North East? Help!
I noticed today that my Aurora Power One invertor control panel has been displaying "Missing grid", the power light is flashing and the alarm has been illuminated. There is no display on the meter. Now that darkness has fallen everything is blank. The co based in Newcastle that installed the unit 13 years ago has now moved…

Which EV charger?
Looking at chargers, and I'm wondering what charger I should buy? I'm upgrading to a Sigenergy solar system. Now the predicament I have is, should I also get a Sigenergy AC charger and have the system work "as a single pane of glass" or should I perhaps get something cheaper that's perhaps compatible with Octopus IOG and…

Don't get solar batteries
The maths is simple. If you DON'T have panels, you can sell the electricity you generate to EON for 16.5p/kWh. When you later need the power, you can buy it back for 21p inc VAT (as at Aug 2025, also from EON). So it'll cost you the difference, which is 4.5p/kWh. If you DO have batteries, you'll use your own power and save…

Is it ethical to sell the fact you are in the market for something to advertisers?
As above really. If i know that i am planning to buy a new AC unit for example, I can go on google and search "AC units", click on a few and then the ads will start to come. Every time i see an ad or click it, that company is paying Meta or google. With an AC unit, a quick bit of research says a company could pay £20-£25…

Rainwater harvesting & pumping
I was out and about for work the other day and saw on an allotment someone was using an IBC (one of those big cube shaped plastic containers in a metal cage) to collect rainwater from their shed roof. What with the heat, dry weather and cost of water I was thinking of something like this at home. I've never installed a…

Solar & battery - are they worth it
Spoiler alert - the answer is yes I've read a few threads where there is some debate about the ROI of solar. My view is that whilst a clear ROI might be good, there are a lot of variables (cost & size of system, efficiency of the property, tariff used, dual/single fuel, etc) that can make it look good or less good. Also…
