New technology in the field of solar panel systems
40% more efficient solar panel systems
A team from the Centre of electronics, optoelectronics and telecommunications from the University of Algarve (UALg) in Portugal has developed a technology that can radically improve the efficiency of solar panels. The process, which involves the multiplication of photons (light particles) should benefit from further research. “There are a lot of works,” said Peter Stallingra, research professor at the UALg. “If the hypothesis put forward by our teams is true in practice, we can improve the profitability of energy production of solar panels over 40%, “he said.
Today, solar panel systems fail to operate more than 10% of the sun’s rays that reach the earth. The light particles are too energetic to be absorbed by the photovoltaic cells. The Portuguese team has shown that separating these high-energy photons with the help of nanocrystals and lasers, they multiply into photons at lower energy can be absorbed by the solar panels.
Stallingra Peter points out that in a changing climate where the need to reduce emissions of greenhouse gases is growing, “an increase in efficiency of solar panels would be welcome.” Happy coincidence, the region of Algarve, south of the country can boast of being one of the sunniest in Europe.
Solar panel systems extending between the forests of Belgium:
It is a new plant photovoltaic covering a railway tunnel on the route Amsterdam-Paris high-speed. The plant is the result of an agreement between Enfinity, Belgian contractor specializing in renewable and Infrabel, the national railway infrastructure manager, in addition to common Schloten Brasschaat crossed the tunnel. It is a successful example of public-private collaboration.
“Created to protect the trains from the fall of the trees without damaging the ecosystem, the gallery now has an added value because it produces environmentally clean energy – says Francis, CEO Enfinity Italy – We believe that this could be the future of photovoltaic in Europe: the installation of the panels on surfaces of structures that do not go to blight the landscape. Also in Italy we are working hard on plants on the roof. ”
On the roof of the tunnel, a length of 3.4 km, supporting 16,000 monocrystalline panels Jinko Solar power of 245 Wp. Overall, the photovoltaic surface measures 27,830 square meters for a peak power of installed capacity to 3.92 MWp. Each year, the plant will be capable of producing 3,300 MWh, equivalent to the average annual electricity consumption of 950 households. The energy produced on site will be used to power the trains and the rail network itself: a unique application of solar energy in Europe.
“The energy will serve the Central Station of Antwerp and the rail link, providing fuel for lighting equipment related to the operation of the fitting – continues Zorgno – We would like to raise other European countries to think of PV in this way and consider this type of application “.
According to Belgian legislation, Enfinity has relied on an incentive-350 energy bill amounted to € / MWh. The total investment was 15.7 million euros and the creation of the solar panel system took about two months. Before construction starts, specific studies have been conducted on the impact of wind and vibration caused by trains passing through panels. The works were completed in December, but after the network connection, for entry into the real function was to wait until early June. The solar panel system is now operational and is able to prevent the emission of about 2,400 tons of CO2 on an annual basis. Within 20 years the solar tunnel will save the environment 47,300 tons of carbon dioxide.
