The sector of photovoltaic has made great strides in recent years. Just think that whoever installed aphotovoltaic system in 2005 it 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.
THE advances in photovoltaics they are found in many areas. The duration of the life cycle, as stated, has increased; yields, technologies, supplementary methods, incentive plans have increased, space requirements have decreased and prices have also fallen. Lot of progress were made in the field of photovoltaic disposal.
THE Advances in photovoltaics, the mini inverters
THE advances in photovoltaics are palpable in the area of all accessory devices to a solar system: accumulators, inverters, cleaners, trackers…. Just consider that a system installed only a few years ago carried a single inverter, so a little shade could affect the productivity of the whole system. Currently the photovoltaic systems they are installed with a variable number of mini inverter which in addition to increasing the yield ofplant they are able to lower the cost of installation as they are easier to assemble and manage.
Advances in photovoltaics, the BIPV
Lot of progress have been registered in the BIPV sector, Building Integrated PhotoVoltaics, orArchitecturally integrated photovoltaic systems. Architectural integration is achieved by placing the photo-active part of the system (photovoltaic modules) within the profile of the building that houses it. There are three main installation techniques for an integrated photovoltaic system:
- local replacement of the roof covering with a suitable coating on which the photovoltaic field is superimposed, for example systems with roof tiles, roof tiles or photovoltaic tiles.
- using technologies suitable for integration such as flexible photovoltaics, adhesive photovoltaics or thin-film photovoltaic technology.
- using structural photovoltaic modules that also perform the function of window frame with or without double glazing. Examples of this are photovoltaic windows and glazing capable of producing electricity.
Setting up a small plant at home means making an investment that pays for itself within four years and that can lead, in some cases, to an economic gain net of costs of between 21 and 32 thousand euros. In this regard, we refer you to the article "Earning with photovoltaics“.
A family that decides to install the Photovoltaic at home it is good for the community because it reduces CO2 emissions by about 1,300 kg per year
