Solar quotes - advice
Hi all, First time poster, long time lurker. Like many, I've been putting out feelers for a PV installation due to the increase in energy costs. I would love some feedback on the two quotes below. My gut reaction is that they are both expensive for what they offer. Quote 1 (11.1kWp), fully installed: 30 x SolarEdge Smart…

A few specific solar PV design questions
Hi, I have a few bits of questions and thought it best to bundle into 1 post. Grateful for any help from the knowledgeable people on here, thank you. 1. Realistic system loss% ?I've used the PVGIS calculator to input into my own spreadsheet, so I can model ROI based on our actual usage/patterns - rather than relying on the…

Batteries
In Southern England facing due south with an annual usage of around 7000kwh and a 6k’ish array with for the sake of simplicity normal hourly spread of usage hourly - as a “finger in the air” - what would be the maximum battery storage that one should consider as practically usable, budgetary considerations largely ignored…

Brick temperature outside showing as 12C
Is this normal? I bought myself a thermal image. It's a fairly cheap one from aliexpress, however I figure it's good to at least get something that can show me how much radiant heat something has I went outside, and my house was showing as 12C. My walls inside are showing around 18C. The ambient temperature here is about…

Solar Panel Installations
Late to the boat, but has anyone installed solar panels recently? Really not into anything DIY and the most basic googlefu points to the likes of EON and other big energy companies or the old "rent-a-roof" scheme. Any pointers when it comes to the types of panels, if I need a battery etc, good companies to recommend or…

Solar PV quote - feedback please

Hot water cyclinder in loft
Hi I have a unvented 250 ltr hot water cyclinder located in the loft next to the system boiler which is programmed to heat the water 30 mins in the morning and again late in the afternoon at 60c. The issue I am finding is by early afternoon and late in the evening the water isn't as hot heat and sometimes requires a boost.…

Octopus agile outgoing
I'm just waiting for my G98 which I've been told will be done by Friday this week at the latest. I can then submit everything to join outgoing tariff. How long does it take on average once you press submit to when you're 'accepted' and can start getting paid for what you put back into the grid

FIT Deemed to Export or Opt Out
Hi I’ve read a few threads on this already but can’t seem to find what I’m looking for. We were fortunate enough to have 15 PV panels installed on our house before the government stopped their 25 year guaranteed index linked FIT payment scheme in Oct 2011. So we get around 60p per kWh back currently. We’ve just had a…

Solar Panel installation - Offered worse deal than promised
Hi there, I paid a deposit on my credit card solar panels in Apr 2022, the day after Rishi Sunak removed VAT from them. It got the batteries and panels down to around £12,500 (12 Sunpower Maxeon 5 panels and a 9.2 battery). The company then went silent but then said the manufacturers had stopped making the Maxeon 5 so all…

Yet another Solar installation quote post!
Sorry, there seems to be a lot of these, and I have read through a bunch of them to get a consensus of every quote is unique! So far I have two quotes for a PV installation, where I am looking at panels + battery. My daily usage is around 10-12kWh, and I home work so can use the energy at the point of generation for the…

Octopus Go Faster without electric vehicle
Hi all, We have just installed a solar array with battery storage and were intending to sign up for Octopus Go Faster, but Octopus are no longer offering this to customers who don't have an electric vehicle - which is a shame! As I understand it, part of the intent of tariffs such as this is to move load from times of peak…

Waterbutt - Connect to sprinklers and pressure washer?
I have neither a waterbutt, nor sprinklers or a pressure washer I was wondering if perhaps it'd be possible to use a waterbutt for that, and also if I could basically dump tumble dryer water into there too In addition, I was looking to see if I could perhaps more smartly use the water butt where it gets out through a…

Efficiency of gas radiators?
So, I know that I won't necessarily get an exact answer here, however is there anyway of measuring efficiency of gas radiators? My boiler is 93% efficient, however I'd hazard a fuss that most radiators are 15 years old at the the very least, with ones in the attic being at least 11 years old The house is very well…
