It can also be indirectly converted using CSPs. There are now several devices and structures created which focus and concentrate solar power in various ways depending on the needed use. There are several now several uses of solar power because of the rise of these devices. On Concentration Solar power is concentrated in various ways. When the power enters an inverter, you can get 120 volt AC conversion, the same electricity required to power the house. The connection will be to the utility panel so that appliances and lights will work the same way when the switch is turned on. On Storage If the house is not using a lot of electricity from the solar energy created, the excess energy can be stored in a battery. You can get a device rated at 12 volts or higher for only $100 at a marine supply store or RV store. Next, purchase a battery. Experts recommend that you get rechargeable batteries from available green companies. Get any size of deep cycle 12 volt lead/acid or gel battery. You will need the deep cycle battery for nonstop use. Thermal mass refers to heat storage during daytime and its release after the sun is gone. The windows will make sure that the home stays comfortable any day of the year. Ventilation refers to maintaining the cool inside the home during extra hot days. Passive Solar Heating Passive solar heating belongs to the category of solar space heating. Solar Energy Net Metering Net metering is actually a means for people who use solar energy to power up their homes or work place to be able to sell back to the utility company whatever excess electricity that their home or work place is able to produce using solar energy technology, but is not able to use up. There are now different techniques, methods and systems that depend on solar power to run plants, houses and offices effectively. You should learn more about these systems to determine the best types that will provide you with the most benefits. You can choose to make your own or just purchase one from top manufacturers.
