Everything is not that simple as it seems at first! That is what I would say about the development of solar energy production and massive distribution of solar panels.
There is no way to contradict its useful attributes, especially from the point of environment safety, but there are some obstacles in their rational usage.
In earlier decades mankind was astonished of how simply industry might implement ecofriendly source of energy, but nowadays even common solar panels and wind turbines experienced some changes in their evolution.
By this I mean an emergence of hybrid solar panels.Those hybrids are a set of common photovoltaic panels and solar heating collectors.
In practice, while absorbing solar radiation, the panels often overwarm gradually that causes a major loss of electrical voltage and its decrease in the system.
Being heated by one degree, over twenty-five degrees Celsius, a solar cell loses 0.02 volts of voltage, which is 0.4% per degree Celsius.
As one could guess, this is serious defect of solar panels. In this context, it is reasonable to convert the voltage loss into a useful type of energy.
Solar collectors are the best candidates that are focused on its transformation into heating, appropriate for domestic applications.
It is also essential to equip the solar panels withy cooling devices in order to lessen the energy spared inappropriately.
One of the brightest examples of successful work of hybrid solar panels is Cogenra Solar Company that placed such cells in California in 2010.
The project is rather unusual. Customary photovoltaic modules in this setting are combined with a system of selection of excess heat with a liquid carrier, in this case – water.
This solar thermal power plant produces both electricity and hot water, which can be used for household needs. The system works in a very simple way.
The photovoltaic elements, specifically parabolic mirrors, focus a light output on the detectors made of crystalline silicon.
Behind the last ones there are tubes leading liquid.
The water is warmed by heat exchanger. As one could see, such hybrid solar panels are best for residential areas, where electricity, heating and hot water are among the most demanded public utilities.
It is only one example of how hybrid solar panels might be designed and constructed.
In particular, there are a lot related patents, which are directed on hybrid photovoltaic solar panels improvement, using various compositions and supplementary details.
All of this leads to the conclusion that mankind, or at least the scientific circles, are still bothered with better usage of environmentally friendly sources of energy.
