Does any one know of a site where you can roughly work out how mush money
you will save with solar panels. We are thinking of getting them put we need
to work how much we will save and how many years it would take to get the
Winter and Summer holidays in the alps!!!
There were some articles in the press re environmentally friendly ways
to generate and save energy in the home. They ere inspired by David
Cameron's windmill on his roof.
Solar water heating will save you money on your gas bill but you have to
offset that against the purchase, installation and maintenance of the
system. Not to mention it's inevitable replacement.
How long it will take to pay for itself is down to how much HW you use,.
efficiency of your existing boiler and how much the gas costs.
Estimates you see will be based on ave. family with an average usage and
an average efficiency boiler. As these systems cost thousands it could
be a long wait ...
As gas costs increase there will be more people doing this, costs will
come down and systems will get better. I wouldn't be surprised to see
it becoming quite common in the next decade.
It's the old, "As part of a calorie controlled diet" situation. The
money is usually better spent in other directions, such as stopping the
heat getting out. Or in moving house.
It can, of course, play a part. Just as a wind turbine can - and at
least it tends to be windier in the Winter when more power is needed.
Just as geothermal can, if you have a big garden and/or a pond/river.
It may, of course, come to the situation where solar heating is a
practical cost effective addition to more than a minority of houses. At
which point the cost will have plummetted, as the demand will have
massively grown. At which point there will be newer, better, cheaper units.
Or you can buy one now, knowing that it will be rendered obsolete by
better units long before you have recoupled the cost of buying it..
