There are many options for renewable energy now available but for many households, businesses and even schools, etc the issue is reliability.
Unfortunately (as we saw with home insulation) when the market opens up the cowboys ride into town. Lots of cheap (and nasty) deals abound.
If you are considering switching to renewable forms of energy let SCRAP help. We work with the best in the business and we have found that over the years the best for solar power is LJW Solar (see our industry partner link on our Home Page).
We can also advise and refer you for Heat Pumps and a variety of other smart energy options (see Solatube and SolarStar above).
