Generation for August
Hi, just a quick query, I take meter reading at the end of each month (sad ... I know but I like to know whats going on) and the generation for August = 212kWh, this is less than half what I have normally generated in August since 2012. I know weather wise August was pretty poor. My generation for the last six months,…

How do I automatically switch DHW Gas to Electric as tariffs change?
I have a 250L pressurised DHW cylinder. At present it is heated by a loop from the gas boiler which is controlled very accuratly by a Heat Genius controller. When on cycle it stays within 0.5C of target so all is well. It costs about £1 a day in the summer for the boiler to keep the DHW at temp. What I want to do is take…

G99 knocked back by DNO - trying understand proposed "reinforcemen"
So our DNO has knocked back the G99 application. Our supply is from 11kV overhead, with a 64A (16kVA) transformer serving just our property. The application was for 5kW inverter and AC coupled battery also with 5kW inverter. They've assessed on the basis of the battery not exporting but for some reason they still take…

Batteries and saving sessions
I am just wondering, in term of impact on one’s electricity bill, whether battery ownership is impacting on making money from saving sessions?

Best PV panel cables and connectors to use for replacing existing?
Possibly a long shot, but there may be a PV fellow on here? (I asked on a dedicated electrician's forum with a PV section - no reply...)I've had zero Riso for a while, so I'm going to replace all the external connectors on our ~12-year old panels. Fortunately they are on a garage roof with a high bank beside it, so access…

Chosing a PV inverter size.
Hi.I understand that inverters are, counter-intuitively, chosen to be pushed to their limits in order to maximise operational efficiency, and my 3.2kW system is, for this reason, handled by a 3kW Aurora. But just how much loss would there be to go the next size up, tho' - is there an actual %-age figure to suggest the loss…

Quotes range from 9500-15000 but here are my questions. What minimum wattage are tier 1 panels? Should I get the same brand inverter and…

Solar PV, Battery and Install
I am early onto my PV journey and after some initial research I have got in touch with some MCS approved installers that will install in North East London. Each of the installers have come back with a different design ranging from 12 panels to 20 panels! 18 would be ideal! I have attached the diagram that looks to me most…

Hi, One of the solutions on offer, to comply with DNO restrictions is Solaredge with their DC coupled battery. For those with this system, or knowledge of it, can anyone answer any of these .. 1) does the inverter power apply to just the output, or does it also limit battery charging? For example 3.6kW inverter, can it…

Three Phase requirement for "high usage"
If you've got an EV, and a heat pump I think that'd be high usage enough It seems like Ofgem at least want the network operates to do this for free and have the costs socialised via the standing charge, which makes sense when apparently one in three houses need it…
