The first step to promote the use of solar panels in private homes, shops and buildings took place during the week, in a multi-sector meeting at the College of Engineering in the city of La Plata.
At the meeting they agreed to manage the documents to be presented to the official authorities of the Province, distribution companies and the Controlling Agency of the Province of Buenos Aires (Oceba), to speed up regulations in Buenos Aires, Province of Law 27,424, which allows to "inject" (sell) surpluses renewable energy electricity to conventional energy networks.
As reported, installing solar panels will save up to 70 percent of electricity bills and those who do so in the region can receive prizes. Future constructors will have access to additional meters which can mean up to two floors more than originally planned, provided that the height is respected in accordance with the current regulations.
On the other hand, private users can "sell" to companies surplus production of energy produced by solar panels, which will represent a reduction in payment of electricity bills.
From the Mafferetti company, Juan Manuel Lumbardini, explained that "solar energy is the most desirable subject. Regarding heat energy, solar hot water tanks are the most sold. With regard to photovoltaics, the problem is that there is no special financing and banks offer personal loans. "
Financing in Santa Fe
In Argentina, there are ten provinces that have norms or resolutions in relation to the law to encourage the use of renewable energy at home and possibly inject surplus into the network: Santa Fe, Salta, Mendoza, Neuquén, Jujuy, Entre Ríos, Chubut, San Luis , Misiones and San Juan.
Distributed injections of energy into public networks are made possible by special regulations or in packages that include the promotion of renewable energy in general.
In this way, it is encouraged to manage benefits and incentives for homes, businesses or buildings that use or combine renewable energy, whether in new or existing buildings.
Production of renewable energy for family consumption, free electricity bills, and checks of up to 3,000 pesos are part of the benefits that users have to inject excess energy into the central network in Santa Fe which is added to provincial incentive programs replicated in eight districts awaiting legislation governing the system exchange at the national level.
"We sell energy to the network during the day, when we don't, to have a night when we use more. This exchange system has many benefits, self-consumption, you don't pollute, you save and provinces pay 13,000 pesos per year for eight years and amortize the value of the photovoltaic system, "explained Marcelo Lenzi, neighbor of El Trébol, in the western center. Santa Fe, the first in the province to place solar panels in its home and inject local energy networks.
"The province provides monetary recognition to users, amounting to 5.50 pesos for each kilowatt hour generated from renewable energy. Three meters are installed in homes, one is measuring renewable generation, one is network consumption and the other is a two-way meter that assesses energy in and out, "explained the Secretariat of the Province of Santa Fe.
Official estimates estimate that a family of four has an average energy consumption of 500 kilowatt hours every two months, although that varies greatly depending on the artifacts they have at home.
Install special gauges
After the meeting in the city of La Plata, president of District IV of the College of Technicians from the province of Buenos Aires, Gustavo Tavolaro explained that "this project determines that the use of photovoltaics, thermal solar panels and their use of rainwater will be a conditioning factor so that more closed square meters can be built in many buildings or factories, among other incentives ". And he added that "Those who choose to use energy differently from conventional energy and who care about the environment will benefit."
In a multi-sector meeting that lasted for a week, "we discussed to advance and share the use of renewable energy among all sectors to get maximum benefits. The idea is to join all construction actors, banks and professionals, for trends used in the world's major cities in pursuing important energy savings and the use of rainwater, "said Tavolaro.
As reported at the meeting, in the La Plata case "the letter will be sent to Edelap to begin installing special meters to combine the amount of electricity used by users and solar energy in each period for invoicing." Edenor and Edesur have applied it.
There are also entities such as Apymeco, Acimco, Uocra union, Industrial Union, representatives of local municipalities and members of professional associations of architects, surveyors, engineers and auctioneers. Also participating companies and banking entities, La Plata District leaders and the High Council of Provincial Technician Colleges.
Installing equipment for a house can cost 150,000 pesos. Including two panels and two batteries. Battery maintenance is the same as that of a car battery. And also the installation must be done by a programmer that allows combining the use of solar energy and electricity, so users can choose between them and not lose the surplus energy that solar panels can produce.
It also shows that houses can be isolated in 100% of electricity for two or three days in a row, but the equipment must be larger, with six solar panels and 16 batteries for a house of 200 square meters, for example.
From the Fiasa company, engineer Daniel Lisei said: "Recently inverters have been incorporated into the network, which is equipment, which together with solar panels can produce electricity in parallel with distribution networks. At the state level it is not regulated and will be based on Law National legislation 27,424 which promotes distributed generations with renewable energy with surpluses finally submitted to the network ".
