Individual solar electric photovoltaic rooftop panels are becoming a more familiar sight. Some property owners, and renters, who previously were out of the market can take advantage of an emerging trend: New community-based solar ownership. Solar electric contractors along with developers are incorporating a range of financing and ownership options for these new solar “gardens.”
The concept is pretty simple: if you don’t have a place to put your own photovoltaic solar electric panel, you can invest in a group array or, in some cases, buy an actual panel in an array. Benefits can include net-metered electricity bill reductions and investment gains realized through the sale of related renewable-energy credits. In some states, homeowners may have the option of “subscribing” to the garden’s electricity output to ensure a certain percentage of their household’s supply is being provided by this community resource.
Performing a preliminary evaluation for a photovoltaic solar electric system is the first step in deciding how to effectively incorporate photovoltaic solar electric technology into a new construction or remodel building. The photovoltaic solan electric plan should generate a number of technically feasible photovoltaic solar electric plans for a new construction design or a remodel that will be retrofitted with photovoltaic solar electric technology. The number of photovoltaic solar electric options are increasing with advancing photovoltaic solar electric technology.
The options depend on a number of factors such as the type, location, orientation and size of the building; whether it is a new or existing building; the dedication of the owner and design team to the use of photovoltaic solar electric panels; how far along the building design is when photovoltaic solar electric panels are considered; and the type of exterior building materials that will be used.
Possible alternatives identified during the preliminary plan might include the use of competing photovoltaic solar electric technologies, integration of photovoltaic solar electric into building materials versus the use of photovoltaic solar electric panels, the building loads that will be served by the photovoltaic solar electric system, and whether the photovoltaic solar electric system will be stand-alone or grid-connected.
The basics of solar electric power.
Solar power is probably the cleanest, most viable form of renewable energy available and it can be used in several forms to help power your house. Many gardens now use solar lights or solar garden water features. The availability and wide use of solar power in gardens shows exactly how versatile it is as a source of energy. The technology and the systems are becoming smaller, more compact and better looking than when they were first created and used. Early examples of solar power systems can be seen in California where, in the 1980s, enough solar power panels were installed to power over 10 million homes.
How do photovoltaic electric solar tiles work?
Simply put photovoltaic tiles and other forms of solar energy work by converting some of the energy in sunlight into a clean form of electricity that can be used in our houses. The PV cells consist of a positive and a negative slice of silicon placed under a thin slice of glass. As the protons of the sunlight beat down onto the PV cell they knock the neutrons off the silicon. The negatively charged free neutrons are attracted to the silicon but are trapped by the magnetic field that is formed from the opposing fields. Small wires on the silicon catch these neutrons and when connected in a circuit an electric current is formed.
This reaction gives Direct Current electricity though, and it must be passed through an inverter to be converted into an Alternating Current used in our homes to power any electrical items. Some of the power is lost in this part of the process as the inverter is only around 95% efficient but this is a much greater efficiency than was once available.
The nature of the PV cell means there is little or no maintenance required and there are no moving parts; this means that a typical PV cell can last up to 40 years with no work besides an annual clean.
How can I use solar electric photovoltaics to power my house?
There are several ways to use solar power around the house and not just for powering. You can use it to heat your hot water, heat your pool or even your central heating or if you have plenty of roof space and a reasonable amount of sun you can get a grid tie system; a grid tie system means that not only can you power your entire house but during those times when you create an excess of electricity you can sell it back to the grid. An efficiently solar powered home will be able to reasonably create between 75 and 100% of their own power and because of the grid tie system this means you may not have to pay for electricity ever again.
