Can anyone recommend any companies to install a solar powered system for a domestic supply , had a ridiculous quote from western power to provide a new domestic supply, so i'm looking at solar options,

Dont forget, most production from solar 75% is in the months April - September, but when do you need most power?
Certainly solar output December / January can be pretty slim
I dont know but how about the mole valley f . one 'mole energy' ? they wont be the cheapest but should be sound i wouldve thought .

If you have a stream or river hydro is a far better solution.

Well yes, but i am beginning to realise it's not as simple as you think, then there is the ongoing maintenance, batteries don't last forever do they

I do have a stream, but it's 300 mtrs away so might be too far away

300 metres is nothing. Keep the voltage as high as you can then step down at the house.

We've got a Tesla battery storage system, tacked onto the solar on the farm.
It works well, but had a few teething problems. Not least becasue of BT / wifi / connection faults. The gateway control was replaced under warranty and Tesla came out to see for themselves.
Mole Energy put it in.

Depends on head to start with. is it good enough naturally or can it be ....
is there a beaver 'on' the stream
gogle ' micro hydro power '

Look on here. tell us a few facts and lots of pictures we will soon sort you out and point you in the right direction. Main parameters are highest point of your land and lowest point. Then how much flow in middle of summer and middle of winter.

When you say highest point, i take it you mean highest place with running water ?

Orange dot is highest point with running water 240 mtrs
Green dot highest point on farm 254mtrs
Blue dot lowest practical point of farm 224 mtrs
Purple dot farm yard and dwelling
Distance between orange dot and blue dot is 1000 mtrs in a straight line

Water flow i wouldn't know how to go about measuring that, varies a lot between summer and winter

Highest point does not have to be running water just storage tank/reservoir.

Excellent. So maximum head 30 mtrs Running head 16 mtrs. Looking good just need the flow now.

Simple method using 100mm pipe and sand bags. Place sandbag in stream then place 100mm pipe on top of sandbag then fill round pipe with more sandbags to create a dam. If pipe runs full you have plenty of water to have a useful hydro system on that head.

I would say there would be about a 4" pipe full running , just by looking at it
