The sun has always been a panacea for growing plants, a day on the beach has always been more pleasant in the company of a bright sun but only since the 1980s has the sun started to spread as a source of electricity. A combination of technologies has succeeded in proposing alternative energy sources, leading the list is precisely… the sun!
The Golden Tree is a Beghelli photovoltaic system solution created for those who do not have the opportunity to install a photovoltaic roof but do not want to give up the power of the sun. The Beghelli "Albero d'Oro" photovoltaic system has been on the market for a couple of years, it uses a highly concentrated photovoltaic system that promises to repay the environmental costs of production in terms of clean energy generated with an "energy payback" only 6 months.
The largest solar plant in the world has been operating since yesterday in the Mojave Desert, on the border between Nevada and California, and one of the three owners (in addition to NRG Energy and BrightSource Energy) is Google! The new plant, called “Ivanpah Solar Electric Generating System ”took years to design, build and test but will now be able to generate 30 of all solar energy produced in the United States!
The advantages of the latest generation adhesive photovoltaic panels are obvious: they do not require any final substrate, a rigid base is not required for the installation and so they can be applied to any surface. Unlike thin-film PV which is traditionally bonded to rigid silicon or glass substrates, adhesive PV panels are more flexible and find wider applications.
Solar-powered shutters are just the umpteenth strategy implemented by man to integrate small photovoltaic systems into domestic architecture. After the photovoltaic tiles, the walkable solar tiles and the windows that produce energy, the solar energy shutters arrive.The solar energy shutters are blackout systems that combine the possibility of producing photovoltaic energy with perfect thermal insulation.
How is the performance of a solar thermal system evaluated? The criteria normally used are the operating temperature and efficiency, expressed in terms of thermal power extractable from solar radiation (the latter obviously depends on the geographical area in which the system is located).
The disposal of photovoltaic panels is already a concrete reality: the producers and importers of photovoltaic panels themselves provide for the disposal of the modules. The average life of a photovoltaic system is 20-25 years; however, many companies do not exploit the system until the end of its life cycle and feel the need to replace the old panels by adopting modules that offer better performance.
Solar collector is everything that 'collects' light and heat and turns them into other forms of energy. Plants, for example, are all excellent biological-solar collectors capable of transforming the light and heat of the sun accumulated with chlorophyll photosynthesis into woody biomass. Glass can also be considered a solar collector because it allows the heat and light inside the rooms, leaving the cold and wind outside.
A solar garden lamp with a LED bulb has very low consumption and for its operation it does not require any connection to the electricity grid, this eliminates the need for annoying extensions and power cables. On the market there are solar garden lamp kits with LED technology. LED lamps are highly energy efficient and are well suited for solar power.
The solar thermal panel, or solar collector, is a crucial component of a solar thermal system. The solar thermal panel is in turn composed of a radiator / absorber, capable of capturing the heat of the sun's rays and transferring it to the water tank integrated into the solar thermal system.
A solar thermal system allows you to reduce the costs in your bill by acting on the heaviest item: that of heating. Unlike a photovoltaic system, solar thermal manages to maintain production even at night. Solar thermal, costs and investment recovery How much does a solar thermal system cost?
Earning with photovoltaics is possible: a photovoltaic roof not only allows you to save on your electricity bill, a solar system also allows you to earn by selling the energy produced and not self-consumed. As stated, making money with photovoltaics is possible but not in all cases.
How is solar radiation calculated? The efficiency of a solar system, whether for the production of domestic hot water or for the generation of electricity, depends on the solar radiation available on the collection surface, i.e. on the solar collector. Having precise information on solar radiation is essential not to only to operators to design and size a system correctly, but also to private users in the evaluation phase to find out if the location, exposure and inclination of the plane on which the panels are foreseen are such as to allow proper operation.
Photovoltaics are becoming more and more widespread, unfortunately there are not always favorable conditions to facilitate their installation: such as the presence of shading. Fortunately, it is possible to install portable photovoltaic panels in order to allow the use of photovoltaic solar energy, overcoming the typical obstacles that arise in the construction of a system with greater power.
The photovoltaic sector has made great strides in recent years. Just think that those who installed a photovoltaic system in 2005 obtained modules with a maximum guarantee of 20 years, while the panels marketed today have a higher yield and guaranteed for at least 35 years. Advances in photovoltaics can be seen in many areas.
According to the Solar Energy Report 2014, photovoltaics in Italy recorded over 550,000 operational plants with a cumulative capacity, at the end of 2013, of 17.9 GW. According to data on photovoltaics in Italy, in the last year new plants with a capacity of 1.45 GW have been connected to the electricity grid, of which 21 is given by plants that have not benefited from the photovoltaic incentives.
It's been a long time from the first solar collector to the latest compact solar thermal panel model. The solar collector (also called solar thermal panel), is a device designed to convert solar radiation into thermal energy.The first solar collector probably dates back to the Roman era but there are no official documents, at the time of the Roman Empire the potential of solar radiation by means of the greenhouse effect created by the window panes of houses.
At SolaExpo 2014, Bosch presented photovoltaic accumulators designed to optimize consumption in the residential energy sector. According to the International Energy Agency, IEA, global electricity consumption is set to rise by a third by 2035. A higher request will result in a proportional price increase.
How much does a photovoltaic roof cost? Today we bring you a practical example of module choice, installation and prices. It is not necessary to have an electric car to set up a roof or a photovoltaic garage. Photovoltaic systems are one of the best solutions to efficiently convert light energy into electricity.
The photovoltaic table is an innovative and valuable piece of furniture: on the one hand it furnishes the home and garden and on the other it produces a certain amount of clean energy. modules of the coffee table will be able to produce electricity using any light source, even the LED lamp of the veranda, living room and office.
The energy storage issue (energy storage for use in deferred time) has become much more important after the incentive tariffs on the energy produced have ended and the attention of families and businesses has shifted to self-consumption. Without incentives, it is better to use the energy produced by your photovoltaic system on your own and in full, making production and consumption coincide.
