If the home user is not sure which electrical appliances are the greenest, then they might consult the Energy Saving Trust web site, which does efficiency tests on a range of domestic electrical appliances, to allow the home user to see what models are best and will allow them to save money on their electricity bills. It’s also important that the home user gets the best payback from the Solar Energy Prices they have paid by having their home insulation up to standard. Windows should also be checked for soundness and be draught free so that thermal losses are minimised. The Solar Energy Panels should generate some 40% of the typical house electricity demands and besides this there is a Feed-in Tariff available to eco positive energy generators that gets them a payment for each kW of electricity they generate and also, if they send any surplus electricity to the National Grid, then they get paid for that in addition. So the home user can get a reward for the Solar Energy Prices incurred when they had the Solar Energy Panels put in and if they make the best of their energy efficiency as well, then they ought to see better returns on the Solar Energy Prices. One of the most advantageous things about Solar Energy Panels is that they are easy to sustain, in that the rain might well wash off any dust that lands on them and it is really only where there are trees adjacent that the Solar Energy Panels might well get dirtied with bird droppings or tree sap, that will need to be washed off manually.
