There are also other factors to consider such as maintenance and if the package includes free installation. Some companies will ask for fees to install the panels, while other buyers may opt to install these themselves to save more. Talk to other people who have already tried certain makes and brands and let them give you the pros and cons of each. The main idea behind passive cooling is to reduce the impact of the sun by orienting the landscape and the house so that you get the most benefits out of cool breezes. The home also has to be designed to reduce barriers to air paths through the home to let natural ventilation in. You need to use the right type and size of windows to reduce the heat during extra hot days. Here are some more tips and tricks on how to begin. It's a Renewable Resource Solar energy is considered a renewable resource. This means that reliability can be acquired day by day. You can expect to continue getting power and energy from the sun for several decades without having to recharge batteries or keep purchasing new parts. This is probably the main reason as to why the people during those times, especially in native South and North America, as well as in other parts of the world, worshipped the Sun. Ancient Greece built temples devoted to worshipping their sun deities, namely, Helio and Apollo. Also, the Greek s use of solar energy were not limited to religious purposes, as they even used the solar energy system to incorporate passive solar design in the construction of their houses. Another problem that solar energy systems would encounter would be the integration and retro-fitting of these solar energy systems to the different houses and structures that are already constructed without any solar energy system incorporated in them. Solar Energy in the Future The future of solar energy appears to be gearing towards the better, especially since there are a lot of research and developments that are being done by different researchers and scientists, all focused on finding ways to improve alternative energy systems and technology. Also, there are certain programs that allow solar energy systems user to sell back energy or electricity that they were not able to consume to the utility provider, giving you more ways to save money. Do Sunny Areas Have More Solar Energy Systems? Although the ideal location to place these solar energy power plants to harness sunlight would be in locations that have an ideally hot climate, some places which does not have that hot of a climate are known to have more solar panels than those which have hot climates.
