Europe ranks highest in PV electricity generation capacity

The whole issue is a complex one especially with regard to cost and potential returns on an investment. PV systems are fine in isolation, but how many produce 240V with a current supply which could be deemed usable in the average household. Here is the need for a differing perspective, if many items were low voltage systems and energy efficient the picture changes. If LED lighting systems were used in conjunction with PV's we have a usable source of energy as they are very low consumers for a usable output, so practical. This requires a change in thought from building designers, architects, and those in the industry to promote low voltage systems, particularly in public or commercial buildings. If LED lighting were fitted to communal areas such as stairwells, security lighting, and other none working areas they would be fine, and practical. They also require batteries to store this energy. On the domestic front cost becomes a major issue, many thousands will need to be spent with no returns before 30 years. This is because the figures are based on the best output figures and not an average output figure. We also have to consider those companies jumping on the bandwagon and charging extortionate prices for sales and installation. Many of these are rather vague with the truth, and as with any new technology, many are their to exploit consumers to make vast profits. As we see it clearly needs a radical rethink and some honesty. One final thought, with PV technology development becoming so rapid, todays technology is tomorrows antique.
