LATEST GENERATION SOLAR PANELS
Solar energy has had a great development in recent years especially in increasing the efficiency of the panel in this article will analyze the solar panels of last generation
The new generation of solar panels is approaching.
The new generation of solar panels is coming and is ready to conquer the market. In contrast to current silicone solar panels, these are of ‘organic’ origin. The part that is converting solar energy into green energy is made of carbon.
Sustainable energy is the only way to boost the economy in the future and scientists are making technological progress every day to increase the efficiency of solar cells.
For example, there is currently a new type of solar panels that are ready to be sold. The “organic” solar panels are more environmentally friendly and, recently, their efficiency has also become profitable. That was until then the biggest obstacle to being a commercially interesting investment.
The new solar panels use the same technology found in traditional panels that are placed on the roofs of houses and businesses. Solar cells consist of a photosynthetic layer that captures sunlight and converts it into energy.
With traditional panels, this layer is composed of silicone, but with the “organic” panels, this layer is composed of carbon. This makes the production of these panels much more respectful with the environment.
Greater potential than current technology
The current generation of solar panels converts 15 to 22% of the sunlight collected in green energy. That is why we are not currently using these panels because they do not reach the same efficiency as the solar cells that are currently available in the market.
The ‘organic’ specimens fluctuated around half for a long time, but with a recent test they achieved up to 15%. A new study shows that 17% is possible and scientists say they will soon reach 25%.
This new generation of solar panels will probably be available in the short-term market. It is expected that ‘organic’ solar panels will be put into production within this and five years.
The best solar panel manufacturers in the market
Photovoltaic panels are the basis of any good system and, over time, can make a difference in the recovery time of the investment made and in the profit margins.
Therefore, it is important to choose the best product based on the price and the services provided.
In recent years, many products have been put on the market by many manufacturers, although the real winners in terms of the number of products sold remain the Chinese photovoltaic panels.
However, there are also Italian companies that produce high quality photovoltaic panels.
The list of the 5 best brands of photovoltaic panels not only takes into account the sales margins, but a series of factors such as quality, reliability and the importance of the brand itself.
Sunpower :
The United States does not have many companies specialized in photovoltaics, but Sunpower probably represents only one giant in the sector.
In the past, it has also suffered a period of crisis, but thanks to state subsidies from the Obama administration it has been able to remain in the market.
The undisputed leader in terms of performance, together with Panasonic, presents E20 photovoltaic panels with a performance of 20%. You can also find the E18 and E19 series, with an efficiency of 18% and 19% respectively.
The best of the market is guaranteed by the X series, which achieves the incredible efficiency of 21.5%.
This innovative series also enjoys a special design, thanks to the pure silicon and anti-reflective glass make the installation an architectural work.
Sunpower is synonymous with solidity and quality, thanks also to its 25 years of experience, which in the photovoltaic sector are many.

Panasonic-Sanyo:
The Japanese multinational entered the world of photovoltaic panels thanks to the purchase of Sanyo .
Its solar panels are among the best in the world in their performance, surpassed only by the new models Sunpower X. Its performance is around 20%, a very respectable value, considering that competition stops at values close to 15%.
The HIT series, made in various formats, achieves 19.4% efficiency. The N245 / N240 are made with a black frame and are equipped with a drainage system to keep the surface of the panel itself cleaner.
The N285 model built one year earlier, in 2015, has a nominal efficiency of 18.4%. Finally, the N330 / N325 are the ones with the highest power, since the watts supplied by a single photovoltaic module correspond to its name.
To remember the Amorton special series , made of amorphous silicone , it can therefore take the desired shape and allow an increasing personalization of the plant.

Solsonica :
Among the leading Italian companies in the production of photovoltaic panels, Solsonica is a company with 40 years of experience in the sector.
It presents some types of photovoltaic modules in the catalog, including the monocrystalline and polycrystalline Silver Plus . The first has two power variants: 60 cells from 240W to 260W and 72 cells from 285W to 310W, while the second with higher performance has 60 cells from 265W to 280W.
There is a version of the Silver Plus model called SE, which is equipped with the Solar Edge electronics on board. This panel obviously has advanced control functions and higher performance.
For more advanced architectural solutions, frameless solar panels are manufactured , suitable, for example, for verandahs or greenhouses .
Among the main characteristics of these products we find the highest quality glass, which allows greater efficiency in the hours when the sun shines with less intensity.
Trina Solar :
You could not miss a Chinese brand on the list, with operational offices around the world and an Internet site completely translated into Italian.
The catalog presents several solutions that are suitable for both domestic and industrial installations.
The Quadmax DC80.08 module, for example, guarantees an efficiency of 16.8% and with its 72 cells can produce a power of approximately 205-215W.
Built with square cells, it gives the system a good aesthetic impact compared to many competitive models.
The model DC05A (Honey Series) and the Honey M Plus model close the catalog of monocrystalline photovoltaic panels.
The glass glass module . , which we analyzed in a previous article, is produced by Trina Solar with the name of Duomax Dual Series .
Finally, there is a photovoltaic module designed for the construction of large photovoltaic systems, and this is PC14.
