Photovoltaic Net Metering Systems
Net Metering is the set off between the generated and consumed energy, allowing the consumer to cover a significant, and likely the entire part of energy consumed while giving the opportunity to use the network for indirect storage of the energy produced by the photovoltaic (P/V) system. The term "net" is derived from the difference between the generated and consumed energy within a specific period. This time frame is usually every billing cycle of the consumed energy. If there is excess energy, it is not lost but transferred for use over the next two months and set off for the next period until final settlement in February - March. The maximum installed capacity amounts to 5kW. Applications apply for residential, commercial, industrial and agricultural units.
The application procedure to obtain the license needed for a P/V system is simple and our company undertakes the execution and processing of all the required steps. The average annual energy production of a P/V system is approximately 1850 kWh/kW.
Why Net Metering?
The generated power by the photovoltaic system installed on the client’s premises, is used solely for the needs of that particular property, thus saving energy obtained from the network. Correct calculation of the P/V system’s installed capacity is required because the energy generated must be adapted to the consumer's demand profile. The eligible installed capacity is from 10KW - 2MW and is applicable for commercial and industrial units. The eligible capacity for agricultural units is from 10KW up to 20KW.
A self-generating project offers the investor the opportunity to save a significant amount of funds which is used today for payment of electricity bills and is an ideal energy-saving investment. The investor is introduced to the philosophy of cost effective and rational energy management for his business.
When considering the design and capacity of the P/V system, it is necessary to take into account the annual consumption of the installation to which it will connect. The energy compensation is carried out on an annual basis and any excess energy after the annual offset is neither compensated nor transferred.
Stand Alone Photovoltaic Systems
Stand alone systems are used for agricultural businesses, mountain homes or wherever there is no access to the electricity grid. Such systems allow for efficient solutions even for lighting of roads or other hard to reach areas of the network. Particularly important is the design of such systems, to achieve the continuous operation even in low sunlight conditions.
The stand alone system also requires an inverter to be used for basic appliances such as refrigerator, TV, light fixtures, computer etc. The dimensioning is contrary to the common method of the grid-connected system. First the energy requirements are calculated and then the design of the system. Installations of stand alone systems can be made in cabins, trailers, yachts, signage, location marks (eg lighthouses, billboards etc.) and telecommunication stations.
