a system which uses solar cells to convert light into electricity; consists of multiple components, including solar cells, mechanical and electrical connections and mountings and means of regulating and/or modifying the electrical output.

Yes there are published safety standards for roof top solar power plants. AEPL will ensure that the supply and installation follows all the safety standards applicable.

A PV system that is designed, installed, and maintained well will operate for more than 20 years. The basic PV module (interconnected, enclosed panel of PV cells) has no moving parts and can last more than 30 years. The best way to ensure and extend the life and effectiveness of your PV system is by having it installed and maintained properly. Experience has shown that most problems occur because of poor or sloppy system installation.

Using a solar system to heat a swimming pool is the most common use for solar energy in the United States today. Solar pool-heating systems increase an unheated pool's water temperature by 10 degrees or more, and they can extend the swimming season by two to three months.

What do we mean by photovoltaics? The word itself helps to explain how photovoltaic (PV) or solar electric technologies work. First used in about 1890, the word has two parts: photo, a stem derived from the Greek phos, which means light, and volt, a measurement unit named for Alessandro Volta (1745-1827), a pioneer in the study of electricity. So, photovoltaics could literally be translated as light-electricity. And that's just what photovoltaic materials and devices do; they convert light energy to electricity, as Edmond Becquerel and others discovered in the 18th Century.

PV systems can be blended into virtually every conceivable structure for commercial buildings. You will find PV being used outdoors for security lighting as well as in structures that serve as covers for parking lots and bus shelters, generating power at the same time.

useful power output divided by the total electrical power consumed.

Net metering is a policy that allows homeowners to receive the full retail value for the electricity that their solar energy system produces. The term net metering refers to the method of accounting for the photovoltaic (PV) system's electricity production. Net metering allows homeowners with PV systems to use any excess electricity they produce to offset their electric bill. As the homeowner's PV system produces electricity, the kilowatts are first used for any electric appliances in the home. If the PV system produces more electricity than the homeowner needs, the extra kilowatts are fed into the utility grid.

Yes we can guarantee the no. of units produced per year per KWp installed. This guaranteed generation will vary from location to location. The exact guarantee figure will be incorporated in the commercial contract.

In any case since the contract is based on price per KWH, if the plant produces less, the revenue is less. This means, there is an in-built guarantee and incentive for us to produce the most.

There are four main types of solar energy technologies:

☛ Photovoltaic (PV) systems, which convert sunlight directly to electricity by means of PV cells made of semiconductor materials.
☛ Concentrating solar power (CSP) systems, which concentrate the sun's energy using reflective devices such as troughs or mirror panels to produce heat that is then used to generate electricity.
☛ Solar water heating systems, which contain a solar collector that faces the sun and either heats water directly or heats a "working fluid" that, in turn, is used to heat water.
☛ Transpired solar collectors, or "solar walls," which use solar energy to preheat ventilation air for a building.

First, the fuel is free! Once you recover the higher initial costs of a solar system through reduced or avoided energy costs (that is, lower utility bills), your solar system will require expenditures only for maintenance. And when you include the cost of a solar water heater in a mortgage on a new home, the system often provides a positive monthly cash flow from the first day of ownership.

Second, solar water heaters and other solar technology applications do not pollute. They do not add to the carbon dioxide, nitrogen oxides, sulfur dioxide, and other air pollutants and wastes produced by most of today's power plants, even those that run on natural gas. And they allow you to burn less natural gas in your home, as well.

horizontal angle measured clockwise in degrees from a reference direction, usually the north or south point of the horizon, to the point on the horizon intersected by the object’s line of altitude.

a device used to transfer electrical energy from one circuit to another; with an alternating current, a transformer will either raise or lower the voltage as it makes the transfer.

rate of flow of electric charge, measured in amperes.

solar radiance that is scattered or reflected by atmospheric components, such as clouds, dust, etc.

an electric current that reverses direction at regular intervals.

measure of solar radiation energy received on a given surface area in a given time.

Balance of System. This means the rest of the component parts and equipment used in a Solar system that is NOT the solar modules. The remaining portion of the PV system, inverters, disconnects, wiring, conduits, NOT including the PV Modules.

photovoltaic modules connected together to provide a single electrical output.

interconnected assembly of solar cells; also called a panel.

1,000,000,000 watts.

basic unit of a photovoltaic panel.

☛ 1 the power consumed on an electrical circuit.
☛ 2 a power-absorbing device, such as a blender, light bulb, etc.

to add a power-absorbing device to an electrical circuit .

measure of kilowatt production of power in kilowatts and time in hours.
