The first step to promoting the use of solar panels in private homes, shops and buildings took place during the week in a multisectoral meeting at the La Plata Technical College.
At the meeting, they agreed to manage a document to be submitted to the provincial authorities, distribution companies and the Oceba province's control agency to speed up regulation in Buenos Aires province of Law 27424, allowing it to "inject" (sell) excess electricity from renewable sources in the conventional energy grid.
As reported, installing solar panels would save up to 70% of the electricity bill, and those who do this in the region could receive awards. Future constructors will have access to additional meters that could account for up to two floors more than initially planned, provided that the height is respected in accordance with current regulations.
On the other hand, private consumers could "sell" the company the surplus of energy generated by solar panels, which would be a reduction in the payment of the electricity bill.
From the company Mafferetti, Juan Manuel Lumbardini, he explained that "solar energy is a topic of interest to the vast majority.In terms of thermal energy, solar hot water is the one that sells the most.As regards photovoltaics, that there is no special funding, and banks offer personal loans. "
Funding in Santa Fe
In Argentina, there are already ten provinces that have legislation or resolutions on legislation to promote the use of renewable energy sources in the country and the possibility of surplus in the network: Santa Fe, Salta, Mendoza, Neukken, Jajui, Entre Rios, Chubut, San Luis, Miresnes and San Juan.
Injecting energy into the public network in a distributed way is implemented through specific regulations or within a package that includes the promotion of renewable energies in general.
It is thus encouraged to manage benefits and incentives for homes, businesses or buildings that use or include renewable energy in new and existing buildings.
The production of renewable energy for family consumption, free electricity bills and checks of up to 3000 pesos are part of the benefits that consumers need to bring the excess energy into a central Santa Fe network that has been added to a provincial incentive program replicated in eight the district, await a law regulating the exchange system at national level.
"We sell energy on the net during the day when we are not, to have the night when we use it more." This exchange system has many advantages, personal consumption, no pollution, save, and the province pays 13,000 pesos a year for eight years and amortized the value of the photovoltaic system, "said Marcello Lentici, a neighbor of El Trébol, in the western center of Santa Fe, the first in the province to place solar panels in his house and inject the local power grid.
"The province provides monetary recognition to consumers of 5.50 pesos for every kilowatt hour of renewable energy generated in the house, three meters, one of which measures the generation of renewable sources, the other is the consumption of the grid and the other is a two- which assesses the penetration and exit of energy, "explained the provincial secretariat of Santa Fe.
The official estimates indicate that a family of four has an average energy consumption of 500 kilowatt-hours per month, although it varies considerably depending on the artifacts they have in the home.
Install special counters
After the meeting in La Plata, President IV of Buenos Aires Technical College Gustavo Tavalaro explained that "the project states that the use of photovoltaic, solar thermal panels and the use of rainwater would be factors that could be built in many buildings or factories, among other incentives. " And he added this "Those who choose to use energies other than conventional energies and care for the environment would be helpful."
In the multisectoral meeting that took place during the week, "we discussed the progress and share the use of renewable energy sources in all sectors to maximize the benefits." It is the idea that all construction stakeholders, banks and professionals join the trend used in major cities of the world to pursue the imperative energy saving as well as the use of rainwater, "Tavalaro said.
As reported in the meeting, in the case of La Plata, "a letter will be sent to Edelap to begin installing special meters to combine the amount of electricity used by the user and solar power in each period to be invoiced." Edenor and Edessur have already applied it.
There were also sites such as Apymeco, Acimco, Uocra Guild, Industrial Union, representatives of the local municipality, and members of professional associations of architects, surveyors, engineers and auctions. Also participating companies and bankers, leaders of the La Plata area and the High Council of the College of Provincial Technicians.
Installation of house equipment can cost 150,000 pesos. Includes two panels and two batteries. Caring for the battery is equal to the one that has to take care of the battery of the car. And the installation should also be done by a programmer that combines the use of solar energy and electricity so that the user can choose between them and not lose the surplus energy the solar panel can generate.
It was also pointed out that one house could be isolated in 100% of electricity for two or three consecutive days, but the equipment should be bigger with six solar panels and 16 batteries for a house of 200 square meters, for example.
From the company Fiasa, engineer Daniel Lisei said: "Recently, the inverters are included in the network, which is an equipment that together with the solar panels can generate electricity in parallel with the distribution network, and it is not regulated at national level and will be based on National Law 27.424, which promotes distributed generation with renewable energy sources with a possible surplus transferred to the network.
