While the family market is being served with green energy answers, in particular Solar Energy Panels and wind turbines, these two answers have advantages and disadvantages that can change suitability for the domestic customer. The Solar Energy Panels work by converting sunlight into electricity and the more sunlight there is, the more electricity is created. Wind turbines need to be spun by the power of wind on the blades that spins a dynamo and so creates electricity, the more powerful the wind the more electricity is created. It is not simply the Solar Energy Prices or the wind turbine prices, but, the different way that Solar Energy Panels and wind turbines deliver electricity. Solar Energy Panels can still deliver electricity on cloudy days, but wind turbines need a wind speed around 5 m/s to turn. How often have we seen big wind turbines, visible from major roads, standing idle? Both Solar Energy Panels and wind turbines are vulnerable to the effects of close buildings and trees because of the shading effect on Solar Energy Panels and disturbing the air flow to wind turbines. It could be that wind turbines are more vulnerable to disturbances in the air flow from buildings and trees, possibly because of turbulence, whereas if it is just trees, then possibly Solar Energy Panels, installed onto the building roof, could actually be able to pick up sunlight directly.
On the cost side, Solar Energy Prices seem to be around ?12,000 for a installation suitable for a normal building, and for wind turbines, the cost is around the ?14,000 mark. There could be other charges involved, for example if the roof is not strong enough to take the weight of the Solar Energy Panels, then the domestic customer could find that the Solar Energy Prices rise somewhat to cover for strengthening the roof. By the same token for wind turbines; they need to be installed either to a post fixed to the ground or to the roof, so that the turbine blades can get an uninterrupted flow of wind. There could also be upkeep costs involved for wind turbines from the reason of the moving parts, whereas Solar Energy Panels need to be kept clean, which could be accomplished by rain fall.
