Solar power cell kit house and home energy

A solar cell made from a monocrystalline silic...Image via Wikipedia Unfortunately, the reality didn’t quite match up with the dream. Solar power cells were ( and still are) expensive to manufacture, and unless you had a lot of panels exposed to a lot of sunlight, solar power systems didn’t produce very much power. However, now that we’re seeing more refinement and advancements in solar power technology, along with growing popularity of renewable energy systems we may be witnessing a rebirth in solar power systems, at least in certain environments.

Solar PV (photovoltaic) uses energy from the sun to create electricity to run appliances and lighting. PV requires only daylight - not direct sunlight - to generate electricity.

Though solar panels still absorb solar energy when it’s cloudy outside, they absorb much more energy and therefore produce more power if they’re exposed to direct sunlight. Solar power systems are therefore much more effective in Tucson, AZ, then they are in Seattle, WA. Also, solar power systems produce more power during longer days, so short Alaskan winter days aren’t very good for solar systems. The ideal environment is in the desert, with long days and little cloud cover.

Photovoltaic systems use cells to convert solar radiation into electricity. The PV cell consists of one or two layers of a semi conducting material, usually silicon. When light shines on the cell it creates an electric field across the layers, causing electricity to flow.

To be effective, solar power systems don’t need to power an entire business community orSolar Water Heating: A Comprehensive Guide to Solar Water and Space Heating Systems even provide all of the power for a private residence. Solar power systems are much more efficient at heating water than they are at producing power. Since standard hot water heaters can consume over a third of a house’s energy, replacing a gas-powered hot water heater with a solar powered heater can reduce a home’s energy bill considerably, as well as making the owners eligible for a tax cut in select states. In the UK on behalf of the DTI the goal of the Energy Saving Trust’s Solar PV programme was to create a long-term, sustained and viable market for solar photovoltaics.

Prices for PV (solar power) systems vary, depending on the size of the system to be installed,
type of PV cell used and the nature of the actual building on which the PV is mounted. Kits are available for DIY installers and contractors to install solar power cells in new houses and also to retro fit during refurbishment projects.

Solar power systems are also very useful for providing power in locations which are hard to reach with standard power lines. They’re extensively used for cell phone towers and other reflective antenna arrays located on mountaintops and other hard to reach places. Since these installations don’t require a great deal of power or maintenance to run, solar panels can provide plenty of power without needing to be maintained or refueled. Though we’re probably still quite a ways from a completely solar-powered society, we’ll likely see many more solar powered devices as solar technology becomes more refined and more efficient.

PV arrays now come in a variety of shapes and colours, ranging from grey ’solar tiles’ that look like roof tiles, to panels and transparent cells that you can use on conservatories and glass to provide shading as well as generating electricity. As well as enabling you to generate free electricity they can provide an interesting alternative to conventional roof tiles!
