Replacing faulty and old solar panels with higher wattage. FIT question.
Current situation is 12x200w panels on roof of 3 storey house. Panels are 12 years old and one has failed, as they are connected in series no power generated! Scaffolding is in place to repair and has cost £800 so wonder whether l should consider replacing all of them whilst it is up. Cannot get 200w so it is likely the…

Wood burning stoves
These are quite pricey to install but can be pretty cheap to run Do they still have the indoor air quality issues that they've been plagued with in the past? If so, that's a bit of a deal breaker

Two separate battery and inverters on the same house
This might be a daft question. Can you have two separate battery and inverter setups in the same house. I mean separate as in two different brands with totally different charge/discharge rates? I find information that seems to suggest that this is possible with solar inverter and a battery inverter and I am curious whether…

Octopus Flux - Net exporters only?
On other parts of the internet, I've seen quite a few people say Octopus Flux is best for "net exporters" Agile is best if you've got a heat pump because you probably aren't a net exporter. Even then, people often have at least 20 kWh worth of batteries. Then use solar diverters to hear water Go/Intelligent Octopus is best…

Are Solaredge Optimisers Always Worthwhile?
We are planning on putting panels on a sloping roof, orientation 190 DegT (just W of South). There are no obstacles to cause shading. One installer gave a detailed pitch on how the Solaredge optimisers work, but his concrete examples with figures were all where shading occurs at certain times of day, for example from a…

Using Growatt hybrid inverter with third party batteries
Is it possible to add non-Growatt batteries to a hybrid Growatt inverter (SPH3600), which already has one 65.kWh Growatt battery connected? For example, it seems that I can buy an array of Nissan Leaf batteries for a few hundred pounds. That's only a small fraction of what a Growatt unit would cost. Can I connect these to…

Insulating my walls
I have a property built in 1996 which uses white wool fiber in the cavity, I feel like a lot of this has dropped in the walls where its got damp from water tracking across the cavity in places, the house really struggled to maintain heat in the winter and it takes a lot to heat to a comfortable temperature. As I don't…

Solar hybrid inverter - 3.6kWh or 5kWh?
I have recently started looking into getting quotes for a solar + battery installation and been recommended 10x425W panels giving 4.25kWp (south facing). The installer recommended a 3.6kWh hybrid inverter and a 9.5kWh battery. Costwise I've been told there won't be a big difference if opting for a 5kWh inverter, and I've…

Cost of a battery add on to pv?
I have a 2.5kw split over 2 roofs 4 and 2 panels. I'm using around 25% of what I generate. I have a inverter which you can't install batteries too. I have 2 options replace the inverter and install batteries to that in the loft, which I don't like the idea off. Or install another inverter with battery batteries under my…

Trashnothing..??
I've only recently come across this site and I'm somewhat perplexed. The hype seems to insist that it gathers together ads from both Freecycle and Freegle... and yet a cursory investigation of my local scene shows that the vast majority of ads from those two sources don't make it onto Trashnothing... and a whole load of…

Green Central Heating Boiler/Hydrogen Boiler/Air Source Heat Pump - which one and how
I had a quote from British Gas for a Worcester Greenstar regular CH boiler. I have a month to make up my mind about whether I buy it from them. I am assured in writing it is more efficient than my Potterton which is 20 years old and will not last forever and it is anyway inefficient. The total cost is £3,599. I would…

Solar & Battery Install Remote From House
Hi, We didn't look at solar originally as we wouldn't qualify for FIT, however now prices look as if could easily be cost effective. I'm awaiting some opinions an quotes, but wondered if there are any issues with our specific electrical layout. The panels would go onto a metal Dutch barn with a huge S facing (190 Deg to be…
