However, a typical commercially sold, professionally installation solar energy systems would cost you the best part of USD 15,000 to 20,000, or GBP 10,000 to 15,000 (very nasty!). A nice needed regarding up-front trade.

Installing solar powered energy for your property is still incredibly expensive, even with government rebates, and earning your a refund takes more years than most can stand to hold back. So you can't really say equipment has turned around quite yet still.
