The consumption

Self-consumption: "Finally an intelligent energy approach"

Should we look elsewhere than at the financial speculation of photovoltaics to discover its primary utility: self-consumption?

In our alarming context of constant increases in electricity tariffs, the "domestic self-consumption" solution represents both at the country level as at the household level, most certainly the most relevant solution, and deserves to be supported and encouraged at the highest level of global energy transition policies. While the cost of electricity tariffs in France continues to increase, that of photovoltaic electricity production has been decreasing rapidly for several years, as confirmed by SER-SOLER.
The reason is that in situ generation of electricity will soon be more affordable than that provided by the grid.

How to explain this:

The cost of investments planned to renovate the French network amounts to three billion euros per year. An increase is therefore expected of 3,8% (minimum) per year of the tariff of use of the public electricity networks (TURPE). Investments are especially necessary to ensure the safety of the Côte d'Azur and Brittany networks, which are particularly fragile and risk blackout during winter consumption peaks. We know that RTE and ERDF network transport mainly represent a fairly high part of this rise in electricity prices in the coming years.

Alas it could not be satisfied that to maintain the network without preparing the deployment of smart meter Linky (smart metering) which will be very expensive.

The consequence is the cancellation of regulated tariffs of EDF decided by the Council of State for the individuals, between August 2012 and August 2013, judging that the increase of 2% decided two years ago by the Ayrault was insufficient.

This decision results in a retroactive invoice for more than 28 million French homes!

The solution is not far, however, and it is also up to each consumer owner to look in this direction, unless resigned, in a good flock of sheep.

Jean-Louis BAL, president of SER, and Arnaud MINE, vice-president of SER and president of SOLER,> declared in a joint press release: "The self-consumption experiment that we recommend could prepare economic players for the emergence of a new photovoltaic market, which does not yet exist, and which could be described as a "proximity market"

In order to anticipate the spontaneous development of self-consumption among end-customers, SER-SOLER recommends the establishment of a support mechanism for self-consumption within the framework of a three-year experimental phase, in parallel support mechanisms currently in place, and without this initiative replacing them.

What is self-consumption?

It is a simple photovoltaic system, just sized to the energy needs of its consumers, connected by direct feedback to the electrical installation of a home or building, to consume directly and free electricity, without the need for storage or resale to EDF.

Thus, by self-consumption, we mean the possibility given to any consumer / producer of electricity, to respond to his own consumption, rather than to produce and sell in full for the network. Surplus electricity continues to be injected into the local grid, and this production could soon be enhanced in a number of ways.

Soon, a photovoltaic installation that meets this definition will not necessarily be the property of the consumer, it may belong to another actor contractually bound to the consumer. Any type of producer / consumer can be part of this framework, from residential to industrial through the tertiary.

Any type of photovoltaic installation is concerned, whether it is integrated into buildings, in the form of a power plant on the ground or installed overlay. The central element of the definition is the strong link between the sizing of the photovoltaic system and the consumer's electrical needs.

The search for even partial autonomy must represent the logic of self-consumption, and allow the consumer to get out of that of the photovoltaic financial outbidding in favor of speculation. The resale to EDF associated with the tax credit still in effect in 2013, have helped to make photovoltaic expensive for too long, and to divert from its objective and natural role: to provide free energy by simple means and affordable for all.

The logic makes it easy to understand that by producing its own electricity during the hours of sunshine, one already saves up to 2700 hours (in the South of France) of electricity bill. Some changes of habits and the turn is played, to feed during the productive hours many domestic appliances, to see even its domestic hot water.

It goes without saying that this brings to a much lower investment and much more quickly depreciated than the installation in order to resell its production under contract with EDF. The need for electricity from a home during the hours of sunshine requires only a very small area of ​​photovoltaic modules over-taxation, without the need to de-tile to integrate it to the frame (as for resale) which generally may cause sealing problems.

Of course, the common misconceptions about photovoltaics are tough, such as "The yield is bad". Indeed, the cells currently have an efficiency of 22%, ie a modulus of around 19%. It is certainly not much compared to 100%. But is this really a problem? We seem to forget a little quickly that the primary source (the Sun for those who do not follow!) Requires no transport, no refining, is inexhaustible, safe, pollution-free, waste-free, noise-free, available everywhere without war, fair . The question of yield must therefore be put into perspective with all the advantages that we have just mentioned.

- Photovoltaics would increase the deficit of our trade balance, all panels being made in China: That's right! Just as the purchase of computers, iPhone, ... But small difference with other products, the energy produced is well used in France and therefore avoids the purchase of raw material abroad! Besides, why not make it? How is it that our only manufacturer (Photowatt) has been bankrupted!

- The modules would not be recyclable: Why would not they be? It is glass and aluminum 95%. The recycling system already exists, for example

- The manufacture of the modules would be polluting: We use the same silicon as that which equips all the computers, why to throw the anathema on the PV? In addition, the recycling of PV is much simpler than that of a computer. In addition, it would also be interesting to see the pollution generated by the construction of a power station regardless of its fuel.

- It would not be profitable financially: In the short term, it is certainly true. But in the medium and long term, knowing that the cost of a photovoltaic installation is only decreasing from year to year, that the network parity is already practically reached in certain countries, that besides the costs of the other fossil energies can only 'increase (scarcity of raw materials, maintenance of equipment increasingly expensive, increasingly stringent safety rules, ...), there is no doubt that photovoltaic energy will become cheap energy in a very short time.

In conclusion, the consumer 100% responsible for his own choices, must take control of his energy destiny without being fooled by commercial vampires and financial, or by the weak government. We are not sheep to be shorn in favor of the big energy lobbies.

Self-consumption exists and is already proven in thousands of homes that have not waited. Nor is it the solution to all problems. It is a technology perfectly developed and will still improve if we want to give him the means. Its main advantage is that it is accessible to everyone, wherever it is on the planet and for a cost that keeps decreasing. It is this fundamental advantage that is scary to certain large groups (and governments) and that is worth to photovoltaics this vast campaign of denigration and misinformation. : Arrowl:

PV Cycle has accumulated 10 000 tons of old solar panels collected.
20 European countries participate, 350 collection points.

PV Cycle collects first 10,000 tones of discarded PV modules in Europe

05 November 2014

By the end of October, PV 20 collection of European countries from 350 collection points. The organization has grown from 80 tons in its first year of operation to 10,053 tones today.

European PV cycle has amassed 10,000 tones of collected waste PV modules. The waste management and compliance provider said on Tuesday that the milestone marked a breakthrough in its treatment.

Created in 2007 for and by the PV sector, PV is the only take-back scheme for PV waste management and compliance solutions.

The organization operates a network of hundreds of points, specialized waste transporters and certified PV module recyclers. PV Cycle has steadily increased its collection figures from 80 tones in its first year of operation to 10,053 tones today.

"Having collected such significant amounts of PV module waste, PV Cycle has demonstrated its ability to treat large quantities of waste anywhere in Europe," said Olmina Della Monica, PV Cycle's Operations & Treatment manager for Europe.

Originally a voluntary initiative, the take-back and appropriate disposal of discarded post-production PV modules are now mandatory in the European market. The European Parliament in the field of European Waste Electrical and Electronic Equipment (WEEE) Directive in 2012.

"Since 2010, our collection and recycling achievements have consistently exceeded the EU targets set in the 2012 WEEE Directive. PV waste will significantly increase in the coming years and it is important to show that PV CYCLE is ready to meet the challenges ahead”, added PV Cycle Managing Director Jan Clyncke.

By the end of October, PV 20 had a different collection of European countries with an infrastructure of 350 collection points. ... z3IqYh1xZL

Too bad it does not say what really could be recycled in this story
