What is the best option for installing solar panels on the roof of my house in London?
Should I use solar panels heat water or store Electricity, or both? How is the cost for a 2 bedroom apartment? Can I get a grant – If so how?
The solar panels for electricity are just a waste of time in this part of the country, given the initial expense installation, maintenance costs and replacement battery for three to five years will cost more than paying a standard supplier. As for water, gains can be had useful, ie it has the cold out of the water entering and thus reduce your procurement costs energy base, but not in a great extent. Roll on global warming When these systems become much more viable in these latitudes.
