PV solar array set up

[acuteanxiety]

Hello all

Wondering if anyone could let me know how much they have paid in the last few months or been quoted for this?

We live in a 4 bed semi detached 1930s house with one bathroom.

We have a combi boiler but my husband is a gas safe engineer so we can change our heating system

Possibly we would continue with a combi and then also have a solar unvented cylinder

There's 5of us in the house, 3 children under 6

We are south east,

In Thanet so any sort of price guide would be fab

We got a quote for 12k

Wondering on any ideas.

Thank you

I don't see why we would store the hot water because it uses SO much energy to store I would like a timer to heat and then when the tank cools that the combi would go go go and give us hot water

I wish it could be used for a wet floor heating system but don't think it can, can it?

Sorry @acuteanxiety, the bit about manufacturer's was for someone else, I can see the breakdown on your quote.
Pylontech and Solis combo is a good combo and the Tigo optimisers on your solar panels will help you overcome any shading issues and allow you to produce the maximum from your system.

If your underfloor heating is fed from your cylinder, then, yes I believe the iboost could feed this, although my knowledge is limited on underfloor heating, maybe give Marlec a call, they'll be able to confirm.

Hello OP. Wally here..... (don't worry, Internet text misses so much communication)

I think the key point is what you would use the energy for? As others have said, selling energy to the grid is a poor rate, so using the energy at home makes sense. Solar for heating needs to be done after the house is well insulated really, short, cold grey days are when you want heating most. I suspect sticking with gas heating is most economical for you.

As a largish family I'd have thought that using it for hot water makes sense. So a solar thermal panel and/or PV panels heating an electric immersion in a (pressurised?) hot water tank. How that might work with a gas combi for radiators, and top up hot water is where it seems tricky. Can a combi be used to heat a hot water tank? Or would it need a new non- combi boiler?

I'm interested in the answer too for our house, and was going to ask our heating engineer at the next service.

A relative has no gas and their house is solar pv and a thermal panel running an air source heat pump for underfloor heating and a hot water tank. It's good, but they replaced the floors and roof insulation to get there and are on the old FIT.

I am going to ask my husband as there is away around this that you time the hot water tank and then when that's empty the combi just heats the shower directly.

I'll get him to give me the information for your relative and come back to you today or tomorrow

Again, I'm so sorry. I am as you guessed by my name anxious and also I am used to hearing people be disrespectful about trades men. He has fabulous reviews and great ratings so I don't know why I'm paranoid, it's me not you,

Sorry again

@Needcoffeeimmediatley

You've been so so helpful, I'll get him to call Marlec for technical info thank you so much
