While the domestic market is being served with renewable energy energy answers, in particular Solar Energy Panels and wind turbines, these two answers have advantages and disadvantages that can change suitability for the householder. The Solar Energy Panels work by converting sunlight into electricity and the more sunlight there is, the more electricity is generated. Wind turbines need to be turned by the power of wind on the blades that turns a dynamo and so delivers electricity, the more powerful the wind the more electricity is generated. It is not just 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 dull days, but wind turbines need a wind speed around 5 m/s to turn. How many times have we seen large wind turbines, visible from the road, standing idle? Both Solar Energy Panels and wind turbines are influenced by the effects of nearby buildings and trees because of the shading effect on Solar Energy Panels and disturbing the wind direction to wind turbines. It might be that wind turbines are more influenced by disturbances in the wind direction from buildings and trees, possibly because of turbulence, whereas if it is just trees, then possibly Solar Energy Panels, installed onto the house roof, might actually be able to pick up sunlight directly.
On the cost side, Solar Energy Prices seem to be around ?12,000 for a package suitable for a normal house, and for wind turbines, the cost is around the ?14,000 mark. There might be other process involved, for example if the roof is not strong enough to take the weight of the Solar Energy Panels, then the householder might find that the Solar Energy Prices rise rather to cater for strengthening the roof. Similarly 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 a free flow of wind. There might also be servicing costs involved for wind turbines from the reason of the moving parts, whereas Solar Energy Panels need to be kept clean, which might be achieved by rain fall.
