Solar and Wind Energy
(How it Works)


With solar cells sunlight can be converted directly into electricity (solar electricity). This process is called photovoltaic (PV) effect. Official abbreviations are PV cell and PV module.

A solar installation comprises the following components:

• The solar modules, which generate direct current (DC) from solar energy.

 
  • The inverter which converts direct current (DC) into alternating current (AC) of 230 volts.

• The meters which meter the electricity fed into the system.

• The cabling and the mounting frames.

A solar module is an array of small interconnected solar cells. The front of the module is covered by toughened glass, while at the back, protection is usually provided by a plastic film.
The solar energy produced is converted by an inverter into AC, matching the mains supply and connected directly to the mains via a second electricity meter. Thus the PV system is technically independent of the domestic mains and electricity is charged or credited separately.


Renewable energy is energy generated from natural resources—such as sunlight[2], wind, rain, tides and geothermal heat—which are renewable (naturally replenished). Renewable energy technologies include solar power, wind power, hydroelectricity, micro hydro, biomass and biofuels.

In 2006, about 18% of global final energy consumption came from renewables, with 13% coming from traditional biomass, such as wood-burning. Hydropower was the next largest renewable source, providing 3%, followed by hot water/heating, which contributed 1.3%. Modern technologies, such as geothermal, wind, solar, and ocean energy together provided some 0.8% of final energy consumption.[1] The technical potential for their use is very large, exceeding all other readily available sources[3][4] and has been proposed to be primary power source.

Solar & Wind power system can reduce or eliminate your electric bill and also solar power can dramatically reduce or eliminate your exposure to rising electricity rates.
You can take advantage of government Rebates & Tax Credits which could pay for more than 40% of the total system cost. These programs include direct rebates, tax credits, loan programs and other financial incentives. Most systems that we design can pay for themselves in energy savings in as little as 3-6 years.

Solar Pool and Hot Tub Heating Systems

Solar pool heating systems work on a similar principle to a direct system solar hot water heater. However, because the water can heat up too much in a solar thermal system, the collector's glazing is often removed. Using non-glazed pipes or a heating system that resembles a flat black mat prevents the pool water from becoming super-heated as well as reduces costs to the overall system.
While solar pool and hot tub heating systems often are exempted from federal and state monetary incentives and rebates, they often pay for themselves within 1–5 years (depending mostly on where you live).
Wind Power is the conversion of wind energy into a useful form, such as electricity, using wind turbines. At the end of 2007, worldwide capacity of wind-powered generators was 94.1 gigawatts.[1] Although wind produces about 1% of world-wide electricity use,[2] it accounts for approximately 19% of electricity production in Denmark, 9% in Spain and Portugal, and 6% in Germany and the Republic of Ireland (2007 data). Globally, wind power generation increased more than fivefold between 2000 and 2007.
The principle application of wind power is to generate electricity. Large scale wind farms are connected to electrical grids. Individual turbines can provide electricity to isolated locations. In the case of windmills, wind energy is used directly as mechanical energy for pumping water or grinding grain.
