While the home market is being served with environmentally friendly energy choices, in particular Solar Energy Panels and wind turbines, these two choices have advantages and disadvantages that can influence suitability for the domestic customer. The Solar Energy Panels work by converting light into electricity and the more light there is, the more electricity is made. Wind turbines need to be rotated by the power of wind on the blades that spins a dynamo and so creates electricity, the faster the wind the more electricity is made. It is not solely the Solar Energy Prices or the wind turbine prices, but, the different way that Solar Energy Panels and wind turbines create electricity. Solar Energy Panels can still create electricity on overcast days, but wind turbines need a wind speed approximately 5 m/s to turn. How many times have we seen big wind turbines, visible from dual carriageways, 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 may 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 home roof, may in truth be able to pick up sunlight directly.
On the cost side, Solar Energy Prices seem to be approximately ?12,000 for a installation suitable for a normal home, and for wind turbines, the cost is approximately the ?14,000 mark. There may 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 may find that the Solar Energy Prices rise noticeably to cater for strengthening the roof. Equally for wind turbines; they need to be attached either to a pole fixed to the ground or to the roof, so that the turbine blades can get a free flow of wind. There may also be servicing costs involved for wind turbines from the point of view of the moving parts, whereas Solar Energy Panels need to be kept clean, which may be achieved by rain fall.
