Overnight Battery Charging / Storage without Solar
STILL trying to get my head around the idea of using battery storage, which is charged overnight and used next day, then repeat. Questions like; 1) What's the maximum size storage battery that will charge to 80% on a single-phase residential supply in (lets say) 4 hours. 2) Is that dependant on the size/power of an…

Lowest temp to kill legionella?
So I was experimenting with my boiler last night and I got it down to 45C for the radiators, and that worked fine. I'll try putting it to 42C and see if that works too, and then 40C (lowest) Any way, I was wondering what's the lowest temperature needed to kill legionella? I've seen 60C quoted which is the highest…

hot water diverter and later EV
Hello, We have a fairly large solar PV system with lots of excess (when the sun shines) receiving SEG. We want to add an iboost or Eddi or similar to heat our hot water which currently uses Mains gas. We don't have a battery system at the moment. I am not sure what to go with - we will buy an EV later so want to potential…

Switch from FIT to SEG
Hi All We are looking for some advice: when we installed our 9.6kW Solar panels in 2018 (ground mount), our thatched cottage coudl only reach an EPC D rating. Therefore, our FIT payment is rather low at only 3p per unit. We went ahead anyway, for the green credentials and since we were looking forward to our next hybrid /…

can someone help me understand octopus flexible tariffs
Evening, as I don't have an electric car I am interested in the agile, and the outgoing tarrifs. I can see that the agile EXPORT can vary on the time of day, and that the outgoing EXPORT is a fixed price. But I can't seem to find the tarrif to see how much it is to import electricity, either to top up a battery bank at…

Using PV energy to run a heat pump?
Hi, I'm unfamiliar with all the technology but exploring options to update my house and replace a last-century combi gas boiler (not condensing) with ASHP + HW tank. Will also need a re-roof (+ insulation) as currently between my bed and the stars there is a layer of plasterboard, 10cm-ish of air, then some slate. (Rooms…

Sizing the inverter
Having done a lot of research and analysis, I’m reasonably
comfortable that the best solution for our house would be as follows: 16 x 400W panels on SSE-facing roof 6 x 400W panels on SWW-facing roof c. 10kwh battery iBoost (N.B. brands tbc – that will be the next step once I’ve
decided on inverter spec) …but I’m still…

Government power blackouts and solar PV
www.theguardian.com/environment/2022/aug/23/energy-use-is-a-decision-for-individuals-insist-no-10-and-truss-allies If the government have intentional blackouts, will our solar pv work? Grid-tied solar is designed not to function during power cuts. Are 'planned' blackouts the same as power cuts?

Once you have reached your 3.6kw export limit, can you then use the excess to top up a battery?
Afternoon all. Well obtaining quotes for a solar installation is proving more difficult than I first thought :( As mentioned in one of my first posts I have been given a quote to have 5.6kwp installed on my south facing roof Assuming that next summer will have a few abnormal blue sky days (currently grey and overcast now…

Solar installers damaged my roof
Hi all, as you probably know I've been very pleased with the performance of my PV and batteries. Unfortunately I have now noticed some staining from damp has appeared in two places on the ceiling upstairs. I went up into the loft and found there had been a leak. As we haven't had much rain since install and I have loft…

Adding a battery to an 8 year old solar system
Hi Gang! Ive had 4kw of solar panels on my roof since 2014, and its been great, generating 30,000 kwh so far! With my electricity jumping from 13p to 40p when my fix comes to an end in october, I am thinking maybe i should add a battery to the setup. I have an electric car and am on Octopus go, so ideally the system would…

Electric heating for flat
We have a one bedroom flat in a 1950s block that we let our. It is 45 square meters and on the second floor (i.e. 3rd level). It currently has a gas boiler for the hot water and a gas hob. Heating is via a couple of oil filled radiators. I would like to reduce the heating costs for the tenant and ideally get the EPC rating…

A few very basic solar questions (12 volt setup - not in house)
I am trying to create a very basic solar setup to keep a 12 volt 120 AHr leisure battery fully charged in a garden workshop. Once a week or so I need to draw c. 20 amps from the battery for one to two hours. The rest of the time it is unused. I have bought a 100 watt 18 volt panel, which came complete with a basic…

Really enjoy the me time! initially started off as a way to get fit but looking at fuel prices, I'm all the more happy. But it does involve a bit of…

Solar panels and future mortgage surveys (regarding integrity of roof)
Afternoon all. Whilst I wait for some more quotes to come in for a solar install at my house I asked my neighbour if they have ever considered it. He said briefly, but his concern would be that a future mortgage survey could highlight problems with the roof (my house is 50 years old) and how would you go about fixing it if…

Shower mixer taps, combi boiler
