Looking for some information regarding costs and design

Hi

I am just looking for some information regarding costs and installation .
I live in a semi detached 3 bedroom house in the Limerick area.
Could someone please post some links and information on the costs involved.

Thanks in advance

What exactly would you like designed, costed & installed?

Hi Brian

I am looking at getting solar panels installed for hot water and possible electrical generation.
I want some information on what systems are available and a general costing .

Solar electricity retrofitted onto an existing house is probably not viable until such time as there is a system for selling back your surplus. This is because your consumption never matches your production - you are always either buying a shortfall or selling a surplus - except that at present, in Ireland, you sell your surplus for free.

You can install a system that uses your surplus electricity to heat water via the immersion, and that is a pretty good and maintenance free way to get hot water, but you might find in a year or so that it would be more lucrative to sell your surplus.

For solar electricity, the hardware, in very ballpark terms, will cost €1 per watt, plus about €700. So a 1kw system would cost €1700 plus VAT. Installation depends on how easy the access and wiring is. A bungalow would be cheaper than a 2 story house with old slates.

A proper immersion divert system will cost at least €450. There are cheaper ones, but they cause distortion to the sine wave on the grid.

Thank you for the information.

I was looking for a system as you described that would use the surplus electricity to heat the hot water.
I have a budget of 5000 and am just in the gathering information stage now.
Can anyone recommend a reputable supplier/installer so i can get more information ?.
