The materials will be delivered right to your doorstep in just a matter of days. Even though solar panels and the relative accessories like solar lights are expensive to purchase at the beginning, the total sum you save in the years to come will be bigger, thereby boosting your savings instead of investing in a non-renewable energy source. If the battery becomes full, the extra electricity will be exported to the utility grid if the system is linked to it. Once the solar energy runs out, electricity coming from the utility will take over. The flow of solar energy electricity is measured via a utility meter that spins forward and backward. Solar Energy Fire Hazards Since most solar collectors basically concentrate the sunlight that they are able to collect from the sun, it can be a fire hazard, especially since fire can very easily start if there were very high concentrations and levels of solar energy. These high and dangerous levels of solar concentrations could easily ignite combustible materials, making it a possible hire hazard on any home. The 50kW Big Dish in Canberra, Australia is a great example. The Stirling solar dish mixes a parabolic focusing dish that includes a Stirling heat engine that regularly drives an electric generator. The benefits of Stirling solar over PV cells are the higher conversion efficiency from sunlight into electricity, plus a longer lifetime. DIY Solar Power Before, solar power or solar cell panels are only available in commercial areas and hardware stores. Nowadays, more and more people are trying DIY or do it yourself kits. You can expect to have your own setup in just one day, provided that you have an easy kit to start with. Solar power can be achieved right in your very own home, without the help of a professional. On Installation Even though solar cell panels are readily available in most hardware stores and the internet, not everyone is still capable of installing the devices properly. The initial setup costs may be very expensive for some individuals. Women may especially find that tasks hard to do unless they rely on a professional to do all the work.
