Electricity produced for own consumption

Electricity produced for own consumption

For homeowners, a good way to save money on your electricity bill is to install solar panels on your roof. Prices have dropped considerably in the last two years, so much so that a 20-square-meter installation of solar panels now costs less than 10,000 euros. Ségolène Royal has implemented a decree for faster amortization just before leaving the Ministry of the Environment. Whether the house is located north of the Loire, where the sun is lower, or south, the investment is profitable . The budget is also being lowered in less favorable regions. The new decree, in effect since May, now allows individuals equipped with solar panels to “self-consume”, in addition to the resale of their production to EDF. It is in fact to retrocede 70% of the energy production of solar panels and to keep 30% for its own consumption , mainly acquired during the hottest hours. The resale price at EDF is set for twenty years and amounts to 10 cents per kilowatt hour, there is little chance to see things evolved in the direction of an increase in profitability in the coming years . On the other hand, the savings made on own consumption can be interesting, given the tariff increases of the regulated blue tariff.

The most profitable installation

If the regulated blue tariff continues to increase, for example up to 1.5% per year, the solar panels will be amortized over a period of up to two years less depending on the region. The ideal is to prefer a plant of 3 kilowatts peak (kWp) which is subsidized for 1,200 euros by the Ademe. There are still scams in the sector, such as some simulations that provide for a depreciation of between five and ten years, particularly impacted by a drop in the heating rating of up to 50%. But beware, the energy consumption of the home will only drop by 10 to 15% on average thanks to the installation of solar panels. We must therefore be wary, especially after the signing of the contract the workers sometimes arrive very quickly and once the site started, the retraction is difficult. Another way to produce energy is the individual wind turbine which costs around 10,000 euros. However, its profitability depends on the climate, which is unreliable and can sometimes cause real problems. EDF does not have the obligation to purchase the excess consumption unless the wind turbine is located in a wind power development zone. In addition the resale rate is very low, 0.08 euro per kilowatt hour and only for ten years. Another disadvantage is that there is no longer a tax credit for the purchase of a wind turbine for two years.

Equipping a photovoltaic or wind turbine production can be profitable, it is necessary to have finances that hold the road. If too many credits impact the repayment capacity and plague the budget, a loan consolidation can be envisaged. It is then a question of reuniting all outstanding loans in one, which will have the advantage of a renegotiated rate. A lower single monthly payment will be put in place over a longer period, for a higher total cost of credit.
