The Benefits of Residential Solar Panels
Are you considering Residential Solar panels for your home?
Residential solar panels are a great investment that not only saves you money and can increase the value of your home, but also help the environment. Solar energy is becoming very price competitive with conventional energy sources, and there are many federal and state rebates and incentives in place to compensate you for the power you produce, and also help offset your initial investment. The cost of residential solar panels for your home have declined substantially, falling more than 40% in just the last few years. There has never been a better time to make the switch to clean energy was renewable for your home or business.
The basics of residential panels
Residential panels convert light from the sun energy into electricity using an array of photovoltaic cells convert photons into usable electricity. Solar cells, or photovoltaic cells, are arranged in a grid-like pattern on the surface of the panel to a specific wattage of electricity. Afterwards, several panels are arranged in a matrix and installed on a roof or in an area that energy flow can produce a home or business.
Residential panels typically consist of crystalline silicon and gallium arsenide expensive, produced exclusively for solar cells. More efficient panels are assembled by the deposition of amorphous silicon alloy in a continuous roll-to-roll process. Cells arising from this process are called amorphous silicon cells or A-si. Side panels using amorphous silicon technology, more durable, more efficient and thinner than the crystalline counterparts.
The latest panels function on a molecular or quantum level. These panels are made by the implantation of carbon nanotubes or quantum dots in a treated plastic. In contrast to the silicon-based panels, these panels should be not built in a clean room, and therefore, the production costs are somewhat lower.
Residential panels work by collecting the radiation from the sun and actively convert that energy into electricity. Solar panels consist of several individual solar cells. These cells operate similar to large semi-conductors and make use of a large area pn junction diode. When the cells are exposed to sunlight, the pn junction diodes converts the energy from sunlight into useful electrical energy. The energy of photons on the surface of the solar panel allows electrons to be turned off is stretched in their orbits, and electric fields in the cells draws these free electrons in a direction of flow, from which metal contacts in the cell can generate electricity. The more cells in a solar panel, and the higher the quality of the cells, the total electrical output is capable of producing the solar panel.
How much power can be produced?
The amount of energy produced by solar panels is affected by the quality of the panel, the materials and the technology used in the making of the panel and the time the panel is in use. When purchasing solar panels, it is best to look over the size of the panels and watching the dollar / watt ratio.
Residential solar panels of the same size can produce variable quantities of electricity, this discrepancy is caused by variations in the working age of the solar cells, the quality of the solar cells, and with which technique was used to produce them. Early cells are not as efficient as modern cells. Panels have an effective life of approximately 20 to 25 years, and their value and wattage output decline steadily over time.
Get more out of your residential panels
The best way to get the most out of your residential solar panels is to take steps such as switching to CFL or LED bulbs, invest in energy star appliances, using smart power strips to turn off electronics when not in use, and make sure your windows, doors and insulation are energy efficient.
