Solar Panels Hybrids

Solar Panels Hybrids

From the principles of humanity, man has been part essential in the process of power generation, is of a type that is, there has been a crucial point which has done innumerable studies, should also be referring to performance obtained in the process of conversion of this energy. There are many types of energy conversion processes and each of them is limited by a number of causes, whether mechanical, electrical, environmental, etc, which makes the retrieved performance not optimal enough. In the case of solar energy, specifically in the conversion processes of solar photovoltaics through a solar panel and other existing methods, one of the greatest determinants of such final performance is, among others, the effect of temperature on the photovoltaic panel and the cells that compose it. By the very nature of photovoltaic cells, produced by radiation, temperature increase causes an increase in generated power, but at the same time there is a decrease much greater than the tension around the 2mV per degree Celsius of temperature increase, i.e. a drop in performance between 0.04% and 0.06% per degree Celsius. The overall effect is that the power of the panel decreases by increasing the working temperature of the same. A 1,000 W/m2 radiation is capable of heating a panel about 30 degrees higher than the temperature of the surrounding air, which reduces stress on 2 mV /(celula/grado) 36 cells 30 degrees = 2.16 volts and therefore the power by 15%. It is therefore important to lay the panels in a place in which they are well-ventilated, since the temperature reaching the cells is always higher than the ambient temperature. This situation, which in principle is presented as a problem, served as a starting point for the creation of hybrid solar panels, which dually exploit the Sun’s energy to produce electricity and heat. These solar panels are composed of two superimposed parts; at the top we would have a panel photovoltaic traditional that it will generate an electrical current proportional to the solar irradiation, and below this, clinches a coil that makes the times of absorber of heat, which circulates a liquid inside her calo carrier that picks up the thermal energy produced in the coil and it gives it through a heat exchanger to a solar tank.

Cultivating Tolerance

Cultivating Tolerance

Given your spirit, the habit of doubt, and in your heart, that of Georg Christoph Lichtenberg tolerance when delving into this topic fit the questions: what is tolerance? Are you tolerant? What has legacy le be tolerant? How has it helped you in your personal growth that has prevented him from being tolerant? How tolerance can be grown.? These questions may already have answers on your part and it will have determined the role of tolerance in their personal growth, what brings in their interrelations and as this helps to ensure a favorable emotional balance. Fortunately there is much material written on the subject, and much interest in knowing how operates the tolerance, its significance and above all as cultivating it. ES.geocities.com on the theme exposed, that. If we understand that our beliefs and customs are not neither better nor worse than other people, but simply different, we will be respecting others. You don’t need to share an opinion to be able to consider it as valid as any other.

What is needed is to put themselves in the place of others. From every perspective, things are perceived in a different way. Why analyze group a situation, listening to the opinion of each member thereof, enables us to assess better. Share differences enriches us. Sometimes, throughout the history of people you can see examples whose forms of acting are born precisely the lack of respect for others. Let pass unfair and inconsiderate attitudes is an indirect way of not respecting who suffers from them. Why be tolerant is also defined, take a step forward, make a choice for Justice and peace.

proyectopv.org. defined tolerance, as acceptance of diversity of opinion, social, ethnic, cultural and religious. The ability to know how to listen and accept others, valuing the different ways of understanding and position in life, provided that do not violate the fundamental rights of the person the tolerance if it is understood as respect and consideration towards the difference, such as a willingness to admit to others a way of being and acting different than their own, or as an attitude of acceptance of legitimate pluralism, is all lights a virtue of enormous importance.
