The Solar Energy Industries Organisation estimates that over 200,000 U.S. Houses will be powered off-grid by alternative solar energy by the end of 2010. While the production of solar clobber requires some inputs of capital, energy and materials, the consequential system will supply power for a number of years with very little cost or maintenance. Home solar energy systems, and homes that depend on solar energy stations 'on-the-grid ' have become more well-liked as many states offer motivations to home owners to join the solar revolution. So when you're doing your next home remodeling porject, consider these solar options.
There are three other ways of capturing solar energy for home use: passively, concentrating warmth and light, or by solar cells. Passive solar is the best and cheapest, where there isn't any mechanical action and the heating properties are simply a matter of good design suited to your local climate. Homes can be built to capture or reflect heat through placement, ventilation and materials, maximising summer cooling and winter heating. The "One Tonne Home" in Sweden (designed by Gert Wingrdh) is a nice example of passive solar in action for a cool climate: with a large surface area of walls and darkened windows for heat storage and, and high thermal mass in the walls that maintain an even internal temperature. The home also features a solar system so good it can charge the family electric car!
Solar hot water systems employ passive solar and can cut your electricity bills by 30% dependent on your location. Solar hot water systems are cheap to run, and in overcast weather can be bolstered with and electric backup if you run out of hot water. They work just by soaking up heat through a sequence of water filled pipes and then storing that heated water in a well insulated tank.
Photovoltaics convert light energy into electricity which is either used straight away or stored in batteries. Power from Solar Power cells can scaled to your needs. You might simply need to install solar lights for your garden, or go further and power your entire house with a complete system. The size and value of your off-grid system will rely on your wishes, however a 10kWh system is generally sufficient for the normal family of 4, and will cost you about $US40,000 for an neatly installed system. The real cost maybe a lot less when you apply state incentives supplied in numerous nations. Incentives to get solar systems exist in numerous U.S. States and in California a 'feed-in tariff ' means you can sell your power back to the grid. Many new solar system lease programs such as that offered by USA Solar Energy, Solar City and Lease The Sun to help folks use the emissions and savings reductions of inexhaustible solar energy in their homes.
Concentrating solar collectors are the strategy employed by solar energy stations. Mirrors reflect and concentrate sunlight onto a central location that heats water to turn turbines. Many home made and little scale version are being developed for home water heating like these ones at Build It Solar. This principle is what powers the easy handmade parabolic or flat reflecting solar oven, but on a much more serious scale like that of the 354 MW SEGS thermal Power Plant, in California and the just authorised Blythe solar collector plant that is mooted to power at least 300,000 homes in the area when in open s in 2013.
Once installed , home solar energy systems can offer endless electrical power at a small part of the cost of conventional grid connected power, with the increased feel good of knowing you are doing your bit to reduce carbon emissions and make the future a cleaner, greener place.
