The first photovoltaic solar cells were used in satellites, an excellent way to\u00a0<strong>generate electricity up in space<\/strong>. Check out the chronology involving this type of energy below.<\/p>\n<h3><strong>1990 \u2013 autonomous systems<\/strong><\/h3>\n<p>In the 1990s, the technology became cheaper and became viable for use in isolated houses, street lamps and water pumping systems. In regions where electricity does not reach,\u00a0<strong>It is cheaper to install a stand-alone solar photovoltaic energy system<\/strong>\u00a0than taking the distribution network there. These are the so-called autonomous systems: a photovoltaic panel, a charge regulator and a battery. The battery allows the use of energy at times when there is no sun. We are talking about\u00a0<strong>small systems<\/strong>, for a lamp, a TV and a refrigerator, for example.<\/p>\n<p>In the late 1990s, with the falling cost of photovoltaic panels, grid-connected systems were encouraged in Japan by the \u201cPV Roofs\u201d program, and then by similar programs in Germany and the United States, followed by Spain, the Netherlands, Switzerland and Australia. In 1999, of the 200MWp installed, 60MWp were small grid-connected photovoltaic systems.\u00a0<strong>Grid-connected systems do away with the need for batteries and send energy directly to the electrical grid<\/strong>, so, sometimes you are taking energy from the grid, sometimes you are putting energy into it.<\/p>\n<h3><strong>2000 \u2013 advances in technology<\/strong><\/h3>\n<p>Meanwhile, in Brazil, some institutions such as USP, COPPE, CHESF, among others, were already testing small systems connected to the grid, of up to 6.2kWp. By then, the technology was ready; all that was needed was to make it cheaper and have regulation so that it would be possible to officially feed electricity into the grid of the concessionaire and actually receive a discount on the bill.<\/p>\n<h3><strong>2012 \u2013 grid-connected systems, distributed generation and energy credits<\/strong><\/h3>\n<p>Finally, in 2012, came ANEEL Resolution REN 482\/12, known as\u00a0<strong>\u201cSolar Energy Incentive Law\u201d<\/strong>, which established the rules for access to\u00a0<strong>microgeneration<\/strong>\u00a0It is\u00a0<strong>distributed minigeneration<\/strong>\u00a0to the electricity distribution and compensation systems (net metering) known as \u201cenergy credits\u201d. It is this resolution that\u00a0<strong>regulates the exchange of energy with the electrical grid<\/strong>, that is, it was from then on that it became possible to generate energy on the roof, feed it into the utility grid and get a good discount on your bill!<\/p>\n<p>The creation of this Resolution allowed the owner of a renewable source generator with a power of up to 5 MW to inject into the grid the energy that was not consumed at the time of generation, receiving credits (in kWh) on the electricity bill. The consumer, therefore, pays, each month,\u00a0<strong>only the value of the difference between the energy consumed from the public grid and that generated by it<\/strong>.<\/p>\n<h3><strong>2015\/2016 \u2013 water crisis and the importance of energy efficiency<\/strong><\/h3>\n<p>In 2015, Brazil experienced a severe water crisis, which led to an increase in energy prices. But what is the relationship between the water crisis and energy?<\/p>\n<p>We have an abundance of rivers and our energy matrix is primarily hydroelectric. For this reason, a few years ago, Brazilians tended to think calmly about the hydroelectric issue. However, our lack of action regarding the impacts of climate change has led us to the current situation. Red tariffs level 3 and the possibility of levels 4 and 5. Thermoelectric plants being activated and generating dirtier and more expensive energy.<\/p>\n<p>The equation is not easy to solve. We need to develop economically and, generally, this growth is linked to increased energy consumption. We have not been able to increase energy production to levels capable of keeping up with this demand and, on the other hand, the negative impacts of climate change make the situation even more complicated.<\/p>\n<h2>And how can we work to reverse this process?<\/h2>\n<p>The first action to be taken to solve this equation is called\u00a0<strong>energy efficiency<\/strong>! It allows that, with the same amount of energy, it is possible to produce more or maintain the same levels of production or comfort.\u00a0<strong>reducing consumption<\/strong>. The second action is inevitable and indisputable: we have to\u00a0<strong>clear our matrix<\/strong>\u00a0looking for more sources\u00a0<strong>stable and renewable<\/strong>\u00a0such as solar and wind.<\/p>\n<h2><strong>Shared generation<\/strong><\/h2>\n<p>In this scenario, in 2015, ANEEL improved Distributed Generation with the\u00a0<strong>REN Resolution 687\/2015<\/strong>, which conferred\u00a0<strong>more rights for those who generate their energy<\/strong>, in addition to creating new energy compensation models, increasing the possibilities for those who want to adopt solar energy. Among the changes, which came into effect in 2016, are the increases in the maximum power of energy generators (from 1 MW to 5 MW) and the validity period of credits on the electricity bill (from 36 to 60 months).<\/p>\n<p>Furthermore, a great novelty was the possibility of\u00a0<strong>shared generation<\/strong>. But what does this mean? It means that\u00a0<strong>it became possible to build a large power plant in a remote location<\/strong>, where land is cheaper and the sun is abundant, free from the shadow of large cities\u00a0<strong>and form consortia, associations or cooperatives<\/strong>. In this way, it is possible\u00a0<strong>offer clean energy to many different consumers<\/strong>. If the biggest problems for small consumers, whether individuals or legal entities, were the\u00a0<strong>lack of space and money for installation<\/strong>\u00a0of a photovoltaic system, at home or in the office, you no longer need to worry.<\/p>\n<p>This means that, through consortium or cooperative models,\u00a0<strong>we can have access to a certain amount of renewable energy<\/strong>\u00a0according to our needs. For example, if the property consumes, on average, 300kWh\/month, it is possible to choose to buy between 150 and 250 kWh\/month,\u00a0<strong>or up to the equivalent of the total<\/strong>, since the surplus is not lost, but\u00a0<strong>turns into credit<\/strong>, which can be used for up to 60 months.<\/p>\n<p>There are still small bottlenecks, such as administrative difficulties with distributors, but we can say that Brazilian energy regulations already allow\u00a0<strong>anyone has access to renewable energy<\/strong>.<\/p>\n<p>This modality brings advantages that go beyond environmental ones, since\u00a0<strong>Conventional market rates tend to grow<\/strong>\u00a0increasingly and can fluctuate suddenly depending, for example, on rainfall.<\/p>\n<h2><strong>In practice, how are things happening?<\/strong><\/h2>\n<p>Five years after the regulation of micro and mini distributed energy generation by ANEEL, Brazil reached the milestone of\u00a0<strong>17 thousand connections<\/strong>. Most connections are in the\u00a0<strong>residential segment<\/strong>, around 13 thousand installations. As can be seen in the graph below, Minas Gerais is the leading state in the country, followed by S\u00e3o Paulo, Rio Grande do Sul and Rio de Janeiro.<\/p>\n<figure id=\"attachment_10280\" class=\"wp-caption aligncenter\"><img decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/cebds.org\/wp-content\/uploads\/2023\/06\/energia-solar-ja-e-realidade-03-1024x683.png\" data-srcset=\"http:\/\/www.condominiosverdes.com.br\/wp-content\/uploads\/2017\/11\/energia-solar-j\u00e1-\u00e9-realidade-03-1024x683.png 1024w, http:\/\/www.condominiosverdes.com.br\/wp-content\/uploads\/2017\/11\/energia-solar-j\u00e1-\u00e9-realidade-03-300x200.png 300w, http:\/\/www.condominiosverdes.com.br\/wp-content\/uploads\/2017\/11\/energia-solar-j\u00e1-\u00e9-realidade-03-270x180.png 270w, http:\/\/www.condominiosverdes.com.br\/wp-content\/uploads\/2017\/11\/energia-solar-j\u00e1-\u00e9-realidade-03-770x515.png 770w, http:\/\/www.condominiosverdes.com.br\/wp-content\/uploads\/2017\/11\/energia-solar-j\u00e1-\u00e9-realidade-03.png 1242w, http:\/\/www.condominiosverdes.com.br\/wp-content\/uploads\/2017\/11\/energia-solar-j\u00e1-\u00e9-realidade-03-300x200@2x.png 600w, http:\/\/www.condominiosverdes.com.br\/wp-content\/uploads\/2017\/11\/energia-solar-j\u00e1-\u00e9-realidade-03-270x180@2x.png 540w\" class=\"wp-image-10280 size-large lazyload\" sizes=\"(max-width: 770px) 100vw, 770px\" alt=\"energia-solar-j\u00e1-\u00e9-realidade-03\" width=\"770\" height=\"514\"><noscript><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-10280 size-large\" src=\"https:\/\/cebds.org\/wp-content\/uploads\/2023\/06\/energia-solar-ja-e-realidade-03-1024x683.png\" sizes=\"(max-width: 770px) 100vw, 770px\" srcset=\"http:\/\/www.condominiosverdes.com.br\/wp-content\/uploads\/2017\/11\/energia-solar-j\u00e1-\u00e9-realidade-03-1024x683.png 1024w, http:\/\/www.condominiosverdes.com.br\/wp-content\/uploads\/2017\/11\/energia-solar-j\u00e1-\u00e9-realidade-03-300x200.png 300w, http:\/\/www.condominiosverdes.com.br\/wp-content\/uploads\/2017\/11\/energia-solar-j\u00e1-\u00e9-realidade-03-270x180.png 270w, http:\/\/www.condominiosverdes.com.br\/wp-content\/uploads\/2017\/11\/energia-solar-j\u00e1-\u00e9-realidade-03-770x515.png 770w, http:\/\/www.condominiosverdes.com.br\/wp-content\/uploads\/2017\/11\/energia-solar-j\u00e1-\u00e9-realidade-03.png 1242w, http:\/\/www.condominiosverdes.com.br\/wp-content\/uploads\/2017\/11\/energia-solar-j\u00e1-\u00e9-realidade-03-300x200@2x.png 600w, http:\/\/www.condominiosverdes.com.br\/wp-content\/uploads\/2017\/11\/energia-solar-j\u00e1-\u00e9-realidade-03-270x180@2x.png 540w\" alt=\"energia-solar-j\u00e1-\u00e9-realidade-03\" width=\"770\" height=\"514\"><\/noscript><figcaption class=\"wp-caption-text\">Map showing the number of photovoltaic systems by state (data from April 2017)<\/figcaption><\/figure>\n<p>These are some of the results identified by the research\u00a0<em>\u201cThe Brazilian Distributed Photovoltaic Generation Market\u201d<\/em>, which reached its fourth edition in 2017.
