Solar install Tuesday, not sure what to do about supplier
We are currently on SVR with EDF on a new smart meter installed in April with a £100 credit incentive from EDF to install. Friday 4.55pm I received a phone call from the solar company we were expecting to install our solar system at the start of next month. Can they come and do it on Tuesday as they'd had a cancellation.

FIT and panel replacement
Hi all I have a 2.02 kWh install from 2011 (9 x 225W Polycrystalline) which came with the house when we purchased in 2015. A neighbour has recently removed a large tree from their garden which was shading the install, so I have the opportunity now to make better use of this. Historically this has only generated 1207kWh per…

How low can you go...Daily, Weekly, Monthly, Whatever... electricity grid import
It has been the first week of the year when I have had little or no import from the grid so I am creating this thread so we can brag about how little energy we import in a week. I was surprised at this low figure as we were not deliberately time shifting energy usage. It has been a normal week with cooking, baking ,…

The importance of good design
I've seen the typical memes over the past few days given our summers are getting too hot now where people talk about how our houses are built primarily to retain heat and Americans getting confused as to why we don't have AC even if only used temporarily I was reminded of what a PassivHaus architect said. With good design…

The difference Solar tracking makes
On Monday (26 June) I conducted an experiment with a 370w JA Solar panel which I mounted to a pallet on casters so I could move the panel about and catch the best of the sun. I should point out that the panel is at at ground level in my garden so I do have to move the panel a lot to avoid shadows from trees and roofs and…

I've had my 5.6Kw PV, Lux 3.6 and 6.2Kw batteries for about 7 months now. I switched to flux a few months ago, with good results BUT:My panels are SW facing so at their optimum at peak Flux export time 4-7pm.

Correctly sizing A2AHP
I'm trying to get quotes for two rooms to be air conditioned and then to use the units to heat in winter, my living room has a large volume because it has a mezzanine in it, I estimate I would need at least a 5kw wall unit in there, the bedroom is much smaller and a 1.5kw wall unit would likely do the trick in there. Why…

Tesla Powerwall 2 - Solar generation during power cuf
Hi, This is a question for anyone with a Powerwall 2, configured for backup during power cuts. Does your solar inverter work and charge the battery in this state, if so then what inverter do you have? I guess the same for installations where it doesn't work, it would be worth knowing which inverter types to avoid. Tesla…
