Solar Power Grid Systems

Solar-electricity, or photovoltaics (PV) is a truly elegant means of producing electricity on site, directly from the sun, out of nothing but sunlight, silently, with no maintenance, no pollution, and no depletion of materials.

A photovoltaic (PV) system consists of all the equipment and materials needed to generate and use solar energy, including solar modules, support structure, wiring, inverter, batteries, controller and other peripherals as required by a specific installation.

GPI can build-to-order any custom photovoltaic (PV) system to meet any need, from a smal family home to a large industrial complex, hospital, hotel or resort.

Affordable: Recent technological breakthroughs have greatly reduced the costs of PV ownership - A long-term investment that will save you money and energy for decades, year after year.

Reliable: The PV system reliability and durability are outstanding. Typical GPI PV systems may last 30 years and more with minimal maintenance.

Green: Few power-generation technologies have as little impact on the environment as photovoltaics. As it quietly generates electricity from light, PV produces no air pollution or hazardous waste. It does not require liquid or gaseous fuels to be transported or combusted.

Everyone is familiar with PV cells as solar cells that power watches and calculators. But PV can do much more.

Electricity for residential and commercial buildings

Whether you are considering a retrofit to an existing roof, or proposing a system in your new construction plans, solar electricity can be a viable source of energy for your home or office.

Consumers and businesses also benefit from PV when faced with power outages and future electricity price increases.

Form and Function

Today's PV systems can be blended into virtually every conceivable structure for homes or commercial buildings. PV modules are relatively unaffected by severe weather. Even hail won't harm them.

PV panels serve both form and function. They can even get used as cover that gives shadow or weather protection and generates power at the same time.

State-of-the-art PV modules are now available in a variety of colors and styles, allowing designers to use them as aesthetic elements built right into roofs, skylights, awnings, entryways, and facades.

Semitransparent Panels

Today's modules can even be specified to transmit a percentage - usually 80% to 90% - of natural light. Mixed with nontransmissive modules, these systems create a pleasant environment inside the building, helping to ventilate and cool the building at the same time.

GPI is using especially the semi-transparent RWE ASI THRU? thin-film solar modules for very beautiful solutions. They convince with their brilliant transparency, as a laminated glass or insulating glass element.

Building-integrated PV

When PV systems are properly integrated into a building "envelope," they don't just provide power and light, they contribute to the structure itself. This relatively new concept, called "building-integrated PV", is taking hold. Since a building has to have windows, why not have windows that produce power? It makes financial sense, too, because the savings on conventional structural materials often offset the cost of the PV materials.

Great Strides in Avoiding Pollution

Because PV systems burn no fuel and have no moving parts, they are clean and silent, producing no atmospheric emissions or greenhouse gases that have detrimental effects on the planet.

According to a report from the National Renewable Energy Laboratory (Herig 2000), compared with electricity generated from fossil fuels, each kilowatt of PV-produced electricity offsets every year:

• up to 830 pounds of oxides of nitrogen,
• 1,500 pounds of sulfur dioxide,
• and 217,000 pounds of carbon dioxide,

according to a report from the National Renewable Energy Laboratory (Herig 2000).

These are serious numbers, and the potential of PV-generated energy to make such great strides in avoiding pollution will only continue to climb as the PV industry grows and expands.

Depending on foreign oil?

It seems pretty clear that reducing our nation's dependence on foreign oil is a worthy goal. Using PV protects us against the threats of fuel price volatility and political instability, and it allows us to produce our own energy within our own borders.

How does it work?

Sunlight is made up of tiny packets called photons. All the time more than enough of this energy reaches the earth to meet the energy demand of the whole planet. Photoelectric panels consists of many solar cells, these are made of materials like silicon, one of the most common elements on earth.

The individual cell is designed with a positive and a negative layer to create an electric field, just like in a battery. As photons are absorbed in the cell, their energy causes electrons to become free, the electrons move toward the bottom of the cell, and exit through the connecting wire. The flow of electrons is what we call electricity.
