Using a solar tracker to make photovoltaic panels more efficient

A solar tracker is not something people came up with in recent years. Actually, is not something people came up with at all. Solar tracking is a very common thing in botany, as all plants follow light. The most obvious flower is, off course, a sunflower. It follows the sun with its flower, turning it from east to west. This is the best possible way to make sure the plant […]

Why Solar Power is now the world’s cheapest Energy

As we continue to argue about whether or not it is appropriate to make a strong commitment to renewable energies, energy technologies are advancing the governments of half the world and are on track to turn this debate into something out-dated.

Solar energy, which has been 75% cheaper since it is now already cheaper than any other type of energy produced by coal, oil or gas. But it’s not enough. If solar energy wants to be a global player we have to take into account that it needs to be more profitable than other sources of energy in the short term. In almost 60 countries, solar energy is the cheapest energy to use.

The Battle of Energy Is Given in The Long Run

Although we normally look at the production price of kilowatt per hour, that is not the most interesting reason for the adoption of renewable solar energy. At least, in a context like the current one, in which the renewable ones do not have subsidizations to pay for the investments.

Energy systems with giant structures in investments are done with dozens of years of forecasting. Therefore, the adoption of renewable energies is slow: once a nuclear power plant (or any other type) is built, it is not feasible to switch it off until the end of its useful life. If done, the investment would not normally be recovered.

That is, if we want to study in detail how the composition of the energy market will evolve, we must look at how much it costs solar energy companies to start each energy system from scratch. The short- and medium-term profitability of solar power plants are key in the final decision of businessmen and politicians; Or, in other words, a very cheap energy to produce that requires a very high initial investment will never be adopted.

Solar Energy Enters the Game in Full Power

Unsubsidized solar energy is starting to take coal and natural gas out of the market, and notably, new solar projects in emerging markets cost less than wind power,” a Bloomberg report on the energy industry said a few weeks ago.

And indeed, in nearly sixty emerging countries the average price of solar installations needed to produce every megawatt has already fallen to $1,650,000, down from the $1,660,000 that wind energy costs. This means that the emerging countries (those that were going to assume a greater growth of CO 2 emissions) are going to turn towards totally unstoppable solar energy.

This has brought great news: the wind and solar energy now cost the same or even less than fossil fuels when it comes to generating energy. According to the World Economic Forum (WEF), this is a reality in more than 30 countries, and prices have been stepping up in recent years, which mean that “it comes good.”

“Renewable energy has reached a turning point,” said Michael Drexler, who leads the development of infrastructure and investment in WEF. “It’s not just a commercially viable option, but a completely irresistible investment opportunity, with long-term, stable and inflation-protected return.”

And between the two, solar energy leads the ranking. In fact, it is increasingly cheaper and competitive, within renewable energies. Yes, because its average price was reduced to the US $ 1.65 million per megawatt in almost 60 countries (about 1,100 million Chilean pesos), surpassing the wind. These are the wonderful data from Bloomberg New Energy Finance (BNEF), which were based on the prices of 58 emerging markets, such as China, India, and Brazil.

Renewable energy is gaining battle after battle and is becoming more attractive not only because of its low environmental impact but because it is also more achievable for governments, companies and above all a good business, as Drexler said. Another reason is that most homes now use a solar powered system as the main source of power.

And Why Is It Cheaper?

As explained in Science Alert, the reasons are numerous. For example, the increase in the environmental policies that drive the creation of clean energy, the reduction of the cost of technological equipment, the creation of new business models and a constant increase of investment.

The prices in each country are fluctuating, so the triumph of the sun is not yet global, as it also depends on the levels of radiation, government subsidies, and projects that are being carried out by different solar power companies. However, while fossil fuels are not going to disappear so fast, governments’ growing commitment and incredible technological advances are increasingly pushing the barriers that limit renewable energies. And in this process, the major is taking much of the credits.

In a short while from most homes around the globe will start to mount their solar panel on individual roofs, companies will use a solar panel-stylize design for their building, and solar power system will inevitably become the first choice for most homes and companies.


Solar Energy is Looking Brighter than Ever

The dropping cost of solar energy production makes its full adaptation inevitable.

According to this recent Bloomberg article (https://www.bloomberg.com/news/articles/2016-12-15/world-energy-hits-a-turning-point-solar-that-s-cheaper-than-wind), Solar is becoming the least expensive form of electricity production in the world. 2016 marked the first time that the renewable energy technology out-performed fossil fuels on a large scale.

Not only is this good news environmentally, but economically as well. Our adaptation to solar energy will limit the amount of poison emissions released in to the atmosphere, cleaning the air we breathe as well as slowing down global warming. It also means the creation of more jobs as many larger cities begin to meet the infrastructure requirements for large-scale solar production.

in 2016, the workforce was larger in solar energy than coal, gas and oil energy combined in the United States. According to the U.S. Department of Energy, solar energy employed 43% of the Electric Power workforce in 2016, while fossil fuels combined accounted for 22%.

A little less than 374,000 people were employed in solar, while coal, gas and oil combined had a workforce of a little more than 187,000. Over the last decade, jobs in coal fell 53%, and while natural gas jobs rose 33%, jobs in solar power generation soared a whopping 5,000%.

But how is solar less expensive if more and more people are being paid to build the infrastructure? The cost of building the infrastructure always costs more than the production of the energy. Think of the enormous cost of creating a coal power plant or a nuclear power plant. Recently, though, even building a Solar power plant has become less expensive than building fossil fuel facilities. The energy from solar, once the plant is built, is significantly less expensive to produce.

When you take into account all the current benefits of using solar energy such as improving the environment, creating more jobs, and spending less capital, you can’t afford not to use it.

Electrical Transformer Oil Recovery Methods(Oil Recovery)

An electrical transformer is only as reliable as its component parts. This fully applies to transformer oil, which functions as an insulator and a cooling medium. Transformer oil is under constant stress from high strength electric field and high temperatures; maintaining the quality of the oil becomes more and more difficult with time. With time, the oil ages and loses important performance qualities.

Oil recovery makes it possible to restore quality to standards and to use the product again. Without a doubt, the process is worth it. Unlike regular oil change, recovery has the following advantages:

  • reduction of oil products use and the costs of oil purchases;
  • reduction of waste oil disposal costs;
  • improvement of oil-filled equipment reliability;
  • improvement of environmental situation.

How are transformer oils recovered?

The terms “purification” and “recovery” are often misused and confused. Purification is a part of a full oil recovery process, and by no means is a replacement. Insulation oil is purified to remove particulate matter, water and gas by settling, centrifuging and separation, filtration, heat and vacuum treatment. These methods, however, are not sufficient to remove acidic compounds and other products of aging. Since acidity of the oil has a direct impact on the performance and reliability of the entire insulation system in the transformer, extra treatment is a must. The oil is recovered by adsorbents (bleaching clay, zeolite, silica gel etc). Besides, the oil must be enhanced with additives to stabilize its qualities and reduce oxidation.

Oil recovery using GlobeCore CMM-R unit

GlobeCore has developed a unique CMM-R unit for the recovery of transformer oil. The equipment consists of several sections, each with an important task to completely restore the oil’s performance (degassing section, recovery section, sorbent reactivation and additive injection sections). Fuller’s earth sorbent is used in these units. This sorbent can be restored multiple times and used for many oil recovery cycles. Another important capability of the CMM-R is treatment of oil inside the transformer, either online or offline.
