Using solar energy in the home
If you want to know how to get your home producing green, efficient energy, you may want to consider solar powering your home. Here's all you need to know about using solar energy
Is Solar Energy Right For You?
Depending on whether you opt for Solar PV or Solar Thermal, installing your system can cost anywhere between £3,000-£7,000. The pay offs are definitely worth it in the long term especially with feed-in tariff, which pays you money for producing your own energy.

According to Money Saving Expert, if your system costs £7,000 to install, over a period of 20 years the feed-in payments could generate savings of around £16,000. Initial pay offs might take a while to be seen so this is particularly good if you’re a home owner intent on staying in your home for a long time.
The most popular way of utilising solar energy is to preheat cold mains water so that less gas, oil or electricity is needed to supply hot water. This is usually achieved by putting a solar panel measuring 3–4m2 (3.6–4.8 sq yd) on the roof, facing roughly south.

An installed system costs between £3,000 and £5,000. DIY kits cost from £1,200. Grants are available through the Low Carbon Buildings Programme.
This is slightly more expensive, costing anywhere between £5,000-£7,000 per kWp. Standard roof mounted panels may not be the most attractive addition to your home, but they are the cheapest.

More subtle options include built-in panels, which are within the roof, or solar tiles at the more expensive end, which replace traditional tiles. With Solar PV, the energy travels into your home and any excess energy can be sold on to the National Grid.
Top Tip: Make Sure your Panels are clean!
Your solar collector panels will perform best if they're clean and free from dust, so give them a wipe-over once in a while. A small amount of detergent on a damp, soft-bristled broom will do the trick.
If you take good care of your collectors, they'll probably outlast your tank. Then you can just connect those reliable old collectors to the new tank.
