Lets post about Solar energy tips and costs. Because of shading, insufficient space and ownership issues, 1/5 American homes are simply unfit for solar panels. With the introduction of shared solar, homeowners can subscribe to “community solar gardens”, and generate solar electricity without actually having solar panels on their own rooftops. There are no moving parts involved in most applications of solar power. There is no noise associated with photovoltaics. This compares favorable to certain other green-techs such as wind turbines.
Certain solar cells require materials that are expensive and rare in nature. This is especially true for thin-film solar cells that are based on either cadmium telluride (CdTe) or copper indium gallium selenide (CIGS). Power density, or watt per square meter (W/m²), is essential when looking at how much power can be derived from a certain area of real estate of an energy source. Low power density indicates that too much real estate is required to provide the power we demand at reasonably prices.
The level of solar irradiation that falls upon the earth varies with the geography of the planet. Generally, the closer to the equator the more solar energy but what most don’t realize is that solar energy can be used anywhere. For example, in the sunniest parts of America a solar system will produce on average 4.7 kWh of power per 1 kilowatt of solar panels but in the least sunny areas, such as the mountains and north east, it wills till produce 2.9 kilowatt hours per kilowatt, per day. So although some areas are better than others for solar power it is still viable in almost all locations.
Solar panels (also known as photovoltaic panels) are installed on your home. The solar panels convert light (photons) into electricity (voltage). Each panel is connected to a microinverter that changes the electric current from DC (direct current) to AC (alternating current). Each microinverter operates independently of the others so that if one stops working your system is still generating maximum power. An alternative to being tied to the utility company is an off-grid solar panel system. An off-grid system is similar to a grid-tied system with the exception that all the solar energy that is generated is stored in solar energy battery banks in your home. A charge controller sits between the batteries and the solar cells to ensure that the batteries do not overcharge. With an off-grid system you are 100% electricity independent.
The process of installing solar panels on your home and switching to solar electricity starts with a free survey of your home where we also perform an energy review to determine how photo voltaic solar panels can help reduce your energy costs. We create a custom installation plan that’s efficient and effective without compromising the quality of the results. Before we begin, we will walk you through the entire solar installation process down to the smallest detail to ensure you understand what will be done and how you’ll benefit.
The typical time need to see a return on investment is going to depend on your specific installation. The direction your roof faces in relation to the amount of sun it receives, the number of solar panels you need and whether you install an off-grid or grid-tied system will determine how much money you save each month and how long it takes for you to recoup your investment. A typical solar panel installation takes anywhere from 3 to 7 years to see a return. Read more info on Green energy for you, less emissions for the planet.
