Self-consumption of electricity of photovoltaic origin

Published on : 24 June 20203 min reading time

Preservation of the natural environment obliges the production of electricity for household and professional consumption is now using green energy, in particular solar panels. The wide range of equipment on offer and the proven expertise of professionals in this field make it easier to install and maintain these systems. For users, the lower cost of implementing these systems and the reduction in the electricity bill make self-consumption more attractive. The implementation of photovoltaic devices for the benefit of individuals and professionals in the agricultural, industrial and tertiary sectors is encouraged. However, to really benefit from this system, the Ademe recommends the good dimensioning of the installation. The devices set up must be able to produce the quantity of electricity that the users need.

Knowing how to optimise photovoltaic self-consumption

Ideally, photovoltaic panels for self-consumption should provide the right amount of electricity that not only reduces the bill, but also distributes it to the grid. Some companies working on the energy transition want to help by implementing innovative and appropriate solutions. The use of these tools, such as the one proposed on Domuneo, allows to optimize the management of self-consumption and to reach the set objective serenely.

A real investment that pays off in the long term

Self-consumption is a system legally regulated by an implementing decree and a tariff order. These legal texts aim to simplify access to this system and to motivate users to adopt it, i.e. to produce their own energy. An investment premium is granted to households that produce their own electricity through photovoltaic panels and sell the surplus of unused energy. Beneficiaries receive this premium for 5 years in a row. Its value is :

– 0.09 €/Wc for a generator from 36 to 100 kWp;

– 0.19 €/Wp for a generator from 9 to 36 kWp;

– 0.29 €/Wp for a generator from 3 to 9 kWp;

– 0.39 €/Wc for a generator less than or equal to 3 kWp.

The cost of the purchase of the surplus energy by EDF is 6 cts €/kWh for devices from 9 kWp to 100 kWp and 10 cts €/kWh for ≤ 9 kWp systems.

However, the systems installed must come from a reliable source and be of excellent quality to ensure the desired performance.

Consumer responsibility

In addition to the financial benefits, this approach encourages users to be more conscientious and adopt good habits to better conserve electricity. To this end, the use of more energy-efficient appliances is also encouraged. The sun is an inexhaustible source of energy, but good management of the electricity obtained is always essential.
