Solar thermal panel is exporting my tank heat!
Hi everyone,I have a solar hot water panel on the roof. When I use my boiler or immersion heater to heat my water tank the solar panel will turn on and heat up from my tank. It's driving me mad because it's a waste of energy. For example my panel temp this morning was 8.9 degrees. My tank temp was 44 (bottom the tank 22…

Would like to get solar panels but can't even get a smart meter
I'd like to get solar panels installed and decided that I needed to get a smart meter first to understand my daytime/nighttime usage to see if I would need a battery installed as well as the house is occupied most of the day. Requested a smart meter from my supplier (Bulb) last December. So far, after 8 months, despite…

Solar question
Hi We've got a decent sized south facing detached house which was extended some years ago. The extension gave the south facing roof multiple odd shaped elevations which, according to a recent attempted quote, meant solar on the roof is unviable due to only 1 or 2 of their panels would fit on each of the 4 part south facing…

Are solar panels pointless?
Apparently it can take a minimum of 14 years to break even. Do they even last that long? Does their efficiency also not deteriorate over time? (Plus how do you keep them clean?!) But once installed the technology is 'fixed' at that point in time. And tech moves fast. There you will be in at least a decade with old tech,…

Solar i-boost - ignored for Energy Performance Certificate
Curious to know if anyone who has a solar i-boost and has had an EPC done had the i-boost disregarded and what reason may have been given? My assessor appeared to not know about the i-boost and said he cannot take it into account. The Certificate issued said we could improve our rating if we heated our water by solar (at a…

Export to neighbour
With the price of leccy going up and forecast to hit 50p/KWh I might actually set up an export meter for my neighbor and charge 10p/kWh. Anyone know the logistics behind this and what would need to be done? Of course this is a scouting mission.

Solar PV Export meter
I've just had solar PV installed. I've noticed than my old meter had a solid red light, which I guess means I'm not using the grid electric, now it's darker it's flashing. But the generation meter they've installed does this look correct? The arrows are on "import" surely I should be exporting to the grid.

Solar PV to heat water for central heating
Just an idea because I don't use all that I generate. I have underfloor heating with a system boiler (gas) and a hotwater tank that is heated by both the system boiler and the solar PV. So the question is could I have a 2nd hotwater tank installed, heated by the solar PV that would feed into the underfloor heating system?

Solar monitoring
I'm getting a 2.4kwh system installed over east and west on Monday. This is all new to me. How do you monitor what your using and is there a way of triggering say a smart plug to turn on washing machines and dishwashers when the panels reach the best output?
