and assuming I live that long and don't move house - it's a terrible deal all round, the govt is going to have to do more to reduce energy use in old houses.And 30 years assuming the system runs at the same efficiency and requires no maintenance or replacement parts during all that time.
my attic is insulated, we replaced the boiler when we bought the house. Despite this, we still use a lot of gas as it's a 1970s building with no real wall insulation. My neighbour had external insulation done and it cost 14K - at best it might save me €500 a year, so 28 years to pay for itself. You might suggest it's worth doing anyway for the increased comfort in the house, and if you have the money just lying around then maybe so. But I think the govt is going to have to do more given it's EU obligations, and it's probably worth waiting to see what that is. The same goes for solar.
6kW is a lot of panel, but note that the 6kW rating is the theoretical peak output of the panels in very sunny locations, you'll get a lot less than that in practice over the course of the day. Solar systems in Ireland tend to deliver 75% of their annual output from May to September. The SEAI Solar guide has more detail.Price for 6kw system <snip> If I can use all or most of 6kwh generated
It was published in 2017, using pre-grant numbers by the looks of it. Who is quoting ~10k for a 6kW system including battery? What size and brand panels are they suggesting? Going beyond 12sqm or 50% of roof area requires planning permission, I believe any ground installed system will require planning.that report looks out of date price wise
Again, can you name any of these? Wholesale suppliers are no good if you want to avail of the grant.I received 2 quotes so far coming in at 10 k , one with 2.4 battery and one without . If you look at solartricity website there are good panels for sale for between 105-142 ex vat each .
You can opt for up to a 4kW system with battery, but the grant for the panel element hits the max at 2kW. Average household electricity consumption in Ireland is 11kWh per day, so 4kW of solar or above is overkill in most cases. Too much solar supply causes efficiency problems for the grid too, with large peaks during the middle of the day when demand is at its lowest.How can the govt bring in such a scheme when going for 4kw (max allowance in scheme while also getting a battery) of PW panels will end up requiring PP but ignore this within the scheme.
I'm not in the industry but curious who's quoting 10k for a 6kW system with 2.4kWh battery.Leo you are looking for names of suppliers . Are you in the industry yourself or looking at installing ?
