Polycrystalline solar cells

By applying several coatings the polycrystalline solar cells can also be manufactured in other colours, not just the standard blue tint. Successful experiments have been carried out with yellow, green, brown, grey and purple coatings.

However, these coatings have resulted in greatly reduced efficiency (by 10-30%), as usable light is reflected. These panels are also more expensive.

Using slanted or non-standard panels is not recommended, though sometimes this cannot be helped. The cheapest, and probably the most aesthetic solution, is to use ’dummy’ PV panels.

These do not generate any electricity, but look the same as the normal PV panels, thus creating the same overall image.



Is China the future?

China, which is expected to double its demand for energy in the next 15 to 20 years, currently consumes 45% of the world’s fossil fuels. This will mean that an additional 45% of oil, gas, coal, and mineral resources will have to be found. In the 1970’s oil was changing hands at around $10 per barrel. Today, new fracking techniques (getting oil, rather than blood out of a stone) will cost at least $80 per barrel, and this cost will increase as the oil rich reserves are quickly used up.
