Your person quoting you is overcharging you by thousands, and on that basis alone I would refuse to deal with them
SBSwords wrote: » Thanks. What I'm finding hard to understand is what might make sense for my setup, then I can go looking for best price. Should I be going for 3kw panels and a 5kw battery, or something less for example. There's no hot water tank in my setup so at least that rules out the hot water diverter.

KCross wrote: » Yes, you would need to be careful. Something as simple as someone boiling a kettle could be enough to trip the whole thing over the edge. Personally i wouldn’t take the chance. I’d put 3 or 4 specific sockets on the circuit and the lights and leave it at that. The potential to mess it up is too high imo. And as unkel has said, for the number of times you’d need it is it worth risking it, even if a spark is willing to wire it that way for you?

I think seai should he doing more work on this and giving sample.pric8ng or average price per kw installed, they have all the figures via the grant system..

AidenL wrote: » Whats the procedure for providing for essential load wiring from the battery? Is it just one socket, which extension leads are then run from? Or it it a matter of selecting a number of sockets in the house to be powered? Can lights also be included? With 6watt led bulbs, quite a bit of light could be provided in a house I imagine. Can the boiler and pumps be included?
wexfordman2 wrote: » I only mentioned the eddi to give an idea of the price difference. To be fair , perhaps the company that quoted you did so because 3kw 8s the max space you would have available on your roof, so that mat be what they have based the size on, and that limitation may be what you are stuck with (but not the price).
unkel wrote: » There is no one procedure. All of what you mention can be done. On the one extreme you could have your house rewired to have lights and say your oil / gas boiler and say a few essential sockets forming its own essential load system. On the other extreme, you could have a very simply approach and just wire one wall socket to the AC essential load output of your inverter (like I'm doing)

unkel wrote: » It's a pity you can't fit more. The additional subsidy of €700 per kWh fitted is more than it actually cost to fit them. So it actually subsidises the rest of the system. The bigger you go, the better deal you get If your main roof is full, have you any kitchen extension or garage? If not, have you any space for a ground mounted array of 4 or 5 panels?

unkel wrote: » Lithium batteries are still very expensive. Your battery is bigger than what is normally fitted to a relatively small array like yours. Did the installer give any reason for the sizing? I'd get a quote with a battery half that size and then post back here.

unkel wrote: » Adding extra battery on top, you pay the full going rate which is not cheap. I agree with you that it probably costs more to load it (even with free solar PV that would otherwise go to waste) than to buy at night rate from the grid

My electricity usage from the grid since mid september has been 1084 kwh - Exactly 7 months. Usage since Feb 28 to April 13th has been 75 units from the grid. 75/6 weeks is 12.5kwh a week from the grid or 1.8kwh a day from the grid. I expect to use even less per day between now and Mid September especially now I am better at using daylight. You learn to make more use of it on brighter days and hold off on over cast days. Summer will be painfull looking giving electricity away for free. If I had my time over I would have installed a diverter.
