Photovoltaic wooden shelters

How does photovoltaics work?

The basic constituents of a photovoltaic system are solar cells. These are linked by means of chemical contacts and, connected in this way, form a module which in turn, joined together, are called «panels». The latter generate the actual photovoltaic system. These cells have the ability to convert particles of sunlight into electric current. They are made of silicon (a semiconductor material) and when they are hit by the sun’s rays they produce direct electric current. However, the energy produced in this way is not suitable for use by household appliances or electronic devices: it must be converted into alternating current. To do this, a device is used that transforms the direct current, generated by the system, into alternating current, called «inverter». The possibility of accumulating the energy produced is fundamental: this allows it to be used even at night or when production is more reduced.

The wooden photovoltaic shelters

The photovoltaic shelters have been designed to increase the space destined for energy production, without occupying surfaces that can be used for other purposes. They can also be used in public structures such as car parks, motorway restaurants or public transport stops.The wooden photovoltaic shelters are built using wood derived from plants of different species, treated to be able to resist atmospheric agents, including hail. canopies is gradually replacing other synthetic materials, wood being eco-sustainable. Wood is a natural, decorative element. A wooden pergola can even be considered an embellishment for the garden. The photovoltaic shelter can also be used for purposes such as recharging your electric car,

The construction of canopies and pergolas involves costs that depend on the materials used and the installation itself. For the installation of this type of systems it is necessary to hire sector technicians, even if the procedure requires little time. In fact, specific knowledge is needed regarding the orientation of the panels, the inclination and other factors that affect the performance of the system.In addition, this type of construction is one of the properties subject to tax deductions (up to 50%): being an intervention for energy requalification, you can apply to obtain state incentives, spread over time.In any case, the average cost of 3 kWp photovoltaic wooden shelters (family system) has now fallen to a price that varies between $ 6,000 and $ 7,000, including the cost of inverter and installation. To this must be added the cost of materials for the construction of the canopy and for its assembly.

Photovoltaic wooden shelters: The future of photovoltaics

The forecasts for the future of photovoltaic technology are excellent. In addition to a continuous decrease in costs, the main innovations are three: the first is thin-film photovoltaics: this is applicable to even very large smooth surfaces, with prices lower than those of silicon panels and a consequently lower yield (about 9%). The rollable photovoltaic panels can adapt to a large number of different surfaces, being flexible. These are also applicable as adhesives, so they do not require further installation costs.Finally there are latest generation panels that are able, through a strong electric discharge, to get rid of the dust deposited on their surface, which would severely limit the original performance.
