In order to profit as well as possible from the advantages of the photovoltaic installations, it is preferable to put them on the roof and to direct them towards the South to capture to the maximum solar energy. However, in order to have more increased performance, it is today possible to connect the electric installation to the distribution networks like those of EDF for example.
The operation of the installation
It should first of all be known how the transformation of the solar energy functions which is used in the building. The electricity which is generated by the photovoltaic installations is in D.C. current therefore it is paramount to transform it into alternative course, a transformation which is done via an inverter.
These are the machines which are used for the conversion of the current which will be then connected to the distribution networks of electricity of EDF. In this kind of situation, it is possible to resort to a certain number of photovoltaic solar modules which will be also connected together. Since several modules are used, it would be thus also necessary to use some inverters.
The characteristic of this kind of installation is that it is not necessary to make large investments besides being very advantageous in terms of energy consumption. All which should be done afterwards to profit fully from it is to install a meter.
The maintenance of this system
The installation of this kind of installation does not require any particular maintenance. All that it is necessary to do is to put a platform of monitoring which will be able to locate the breakdowns related to the systems.
The maintenance of the modules is done naturally, because the rain and the wind will be the essential components which will clean the sensors. As regards the energy supply, it is done automatically via the inverters and of connection to the line of distribution. However, in order to guarantee the performance of the system, it is advised to replace the inverters at least the every 1 year.
To resell its electricity
The factor which made it possible to support the resale of electricity is that the European States decided that the public operators suppliers of electricity will have to pay more for electricity coming from renewable energies. They are the energy of the solar installations, the wind mills and the hydraulic electricity which are concerned with this process.
However, the installation more the appraisal for the resale of electricity is the solar panel. To be able to profit from the advantages of this process, it is not necessary to terminate the contract with the suppliers and these are even the latter which will repurchase electricity. In the case of EDF, for example, the producers buy 10 centimes of euro per KW hour the electricity which they consume. If it decides to resell the energy which will be produced starting from the solar modules, EDF will have to spend 60 centimes of euro per KW hour.
The purchase prices will be the object of a quarterly adjustment which will be done especially according to the number of in projects filed near the ministry in charge of energy and of the economy. If the request is important, it could be that the tariff of purchase knows a fall of about 2.6%. On the other hand, if it is less important, the adjustment on the tariff will be also less. |
