Photo Voltaic power plants convert sunlight to electric energy. The energy output of such PV plants will therefore reach it's peak at midday, meeting the daily energy consumption peak, when the spot prices on energy are highest.
Since no local energy storage facilities are needed, the limiting factors sizing grid-connected photovoltaic systems are the available space - often a roof - the investment costs and the regulatory frameworks including subsidy and promotion programs. Such programs can include investment subsidies, net metering or feed-in tariffs. With net metering the inflow of electrical energy is charged up against the electrical consumption at the same estate, using mostly a bi-directional working electricity meter. This system is widely in use in the US and Canada. Since there is in most cases no compensation for an inflow exceeding the yearly consumption, photovoltaic facilities will be mostly sized to provide no more energy than consumed at the same estate during the year; the grid is used only as a storage facility. Within a feed-in tariff system on the other side, providing (like in Germany) fixed and guaranteed payments per kWh, more output means more profit; so facilities will be bigger sized.
Solar Power: Sunlight becomes the source of electricity.
A grid coupled PV system essentially consists of the PV panels (modules), one or several solar inverters, a protections device for automatic shutdown in case of a grid breakdown and a counter for the fed in solar electricity
The components of a grid-connected PV system include the PV modules, a power inverter, a safety device to power down at failures in the grid and an electricity meter. The "mains-commutated" inverter converts the direct current (DC) provided by the modules to alternating current (AC), simultaneously synchronizing the AC output to the AC in the grid.
The power-generating capacity of a photovoltaic system is denoted in kilowatt peak (measured at standard test conditions and a solar irradiation of 1000 W per m²). Today's PV modules will cover an area between 7 and 10 m² per kWp. Assumed that the modules are oriented to south and inclined at an angle between 30° and 35° such a PV system will generate in Middle and West Europe - depending on the exact latitude and other factors - between 800 and 1.000 kWh electrical energy per year and per kWp of nominal capacity. To exemplify: On a roof in Cambridge or Oxford (UK), a 4-kWp-plant with optimized module orientation and module inclination angle will provide about 3.380 kWh per year, at Sevilla (Spain) 5.640 kWh per year. The plant at Sevilla will therefore need an inverter with an higher input voltage than the one at Oxford.
We therefore provide complete solution for the same along with all technical support.
