Photovoltaics/Net Metering

WHAT IS NET METERING?

From the first of January 2015, for the first time in Greece, energy offsetting (NET METERING) between electrical energy consumption and the production of photovoltaic systems is allowed. The consumer will now have the opportunity to produce his own electrical power and dramatically reduce his cost for energy, while protecting himself from possible future increases in electric energy prices, for the duration of the 25 years agreement with the electricity supplier.


HOW DO I PROFIT?

A consumer earns money by practically “locking” a fixed price for electric power for the next 25 years, to an amount that is lower than the current one. Furthermore, the consumer retains the option to become totally independent from the network in the future by adding batteries to his system. He can further increase his profit:

  • If the price for electricity increases in the future
  • If he consumes power at the times when his photovoltaic system is productive
  • If he reduces unnecessary energy use

EXAMPLES

The option for net metering is available to proprietors of properties but also to tenants. Here are two representative examples for home and professional installations respectively:

  • The numbers below come from a small-sized business installation (consumption: 4.000 kWh / 4 months) . All the factors which make the calculations representative of current prices or possible future changes (of prices, consumption, production etc), have been taken into account . For this example, detailed calculations regarding the cost of energy with and without the photovoltaic system have been carried out. The initial cost of the installation of the photovoltaic system itself has been considered and these are the results of the calculations:
  • ANNUAL ENERGY CONSUMPTION12 MWh
    SUGGESTED PHOTOVOLTAIC SYSTEM8,49 KWp
    COST OF INSTALLATION 10.400 €
    INTERNAL RATE OF RETURN16.23%
    DECREASE OF ENERGY COST70%

  • Below are the calculations for a home installation (consumption: 1.250 kWh / 4 months). All the factors which make the calculations representative of current prices or possible future changes (of prices, consumption, production etc), have been taken into account. For this example, detailed calculations of the cost of energy with and without the photovoltaic system have been carried out. The initial cost of the photovoltaic system has been considered and these are the results of the calculations:
  • ANNUAL ENERGY CONSUMPTION5 MWh
    SUGGESTED PHOTOVOLTAIC SYSTEM3,44 KWp
    COST OF INSTALLATION5.200 €
    INTERNAL RATE OF RETURN12.10%
    DECREASE OF ENERGY COST72%
    DEPRECEATION OF THE INVESTEMENT8 έτη



    HOW DOES IT WORK?

    The consumer installs a photovoltaic system which is connected to his consumption. The power that he produces is offset with the power that he consumes.

    The consumer uses the electric power network as a storage facility for energy. During the hours that his production is greater than his consumption, he injects (stores) the power into the network (outgoing power).

    During the hours that his system does not produce or when the production is lower than his consumption, he absorbs power from the network (incoming energy).

    The contract has been designed so as to allow the consumer/producer (prosumer) to maximize his savings if:

    • His photovoltaic production is almost equal to his consumption
    • The consumption of energy coincides, as much as possible, with the hours that the system produces energy.

    WHY CLARUS ESCO?

  • Because from 2009, we have established, funded and are operating more than 100 photovoltaic systems, and have acquired the necessary experience and know-how to handle you installation.
  • Because we provide operation and maintenance services for all our installations (and under certain conditions for installations which have been installed by third parties). These services include preventative maintenance, damage repairs, remote monitoring of the operation (over the Internet or through a mobile network), extensions of equipment guarantees and management of relations with the energy supplier.
  • Because we provide a minimum production guarantee for installations for which we are providing operation and maintenance services. This guarantee is provided through an Energy Efficiency Contract, in which the minimum production level (yearly) is specified. Whenever the system produces less than the specified amount, Clarus will cover the difference.
