Mole energy 4kw solar.?

[vinnie123]

how does mole valleys 4kw solar offerings and the Tesla power wall battery compare to the other systems around?

Seriously considering solar and the availability of battery storage makes it even more appealing.

What’s to look out for?

Perhaps you could post more. It is difficult to believe that any investment now will be paid for in the short medium term

Just looking into the options available and read the mvf newsletter plugging their system.

I believe the FIT scheme is now dead for new entrants, so you are relying solely on paying for the project by utilising all the energy you can.
during the 4 winter months such a scheme will average possibly 4-5 units per day of production.
in the 4 summer months 16-20 units and remember averages are made up of quite a fluctuation. in winter especially so.
can you use enough power to pay it back. I would check all the best power deals before investing.

my own house last year produced 7,800 units from a 7.8 Kw system which if I had used all would have saved me about £1100 on my current supplier of about £0.14 / unit. However I very much doubt I used half that even though I have swimming pool with heat pump. Thanks to the hot summer it was not running most of the time.

Thanks for that @Exfarmer , currently oil fired central heating and bog standard electric contract, just feel like we need to be doing something in the renewable line.....it’s just a cas3 of what? If the maths don’t stack up then nothing will change.

Was chatting to a biomass heating engineer a few weeks ago and even he said you can’t beat oil (with no government money)

I have a biomassboiler heating the farmhouse
And I wish I’d left the oil boiler in
It would have been cheaper to stay on oil !

But I love the biomass boiler itself, just it is expensive to run

As soon as the sub runs out I’ll be plumbing the oil boiler back in

What is this madness?

You sound like a sailor lost at sea resorting to drinking sea water after your first hour on a lifeboat.

Luvely smoky coal, can't beat it. Plenty under the ground as well, need to get it up.

 

[curlietailz]

Why ??
Do you think biomass pellets will drop in price sometime soon?
I don’t
When people jumped on the biomass bandwagon the price of pellets shot up

Oil would be cheaper

Because both fuels are finite and will always deal with volatile price fluctuations.

I’m not a big fan of biomass personally.

What are the costs of pellets per tonne and how much is a litre of oil?

The only biomass boilers that made sense were the Farm 2000 and Dragonheat as they would burn anything. Loved the description of the "superfuel" being used for topping the swimming pool or domestic hot water supply. Dunlop Coal!!

I knew one farm that incinerated all their spray drums in one too

But.. they were/are ace at burning timber from any source.

Insulation is the way forward. Add external insulation, triple glazed windows and mvhr and you won't need any power or oil to heat the house.

Shouldn't be too bad if you follow passive House principles.

I bet it’s nice around your place in the dead of winter huddled around a candle for warmth, fun times. Do you bottle your methane so you’ve got a source for cooking?

Not if you do the MVHR correctly and use the cool overnight temperatures to reduce the core house temperature for the following day.

Woodstove range does all the cooking and hot water throughout the year. Central heating woodstove for the depths of winter no candles required.

Yes, you try sleeping in a house which is 40C. !
I have one!
