This collector is similar to the flat-plat collector with lens that spread the ray over maximum area on the plates (Brown). However, the passive collector is totally different from the other two, because it could be a house or any place that has three features: the light of the sun can goes through this place, the light converts to heat, and the heat stays inside the collector ("Solar Energy." Latent). In general, these collectors of solar energy are the main three ways to produce different energies. .
The main advantage of using solar energy is keeping the environment clean. In fact, it does not cause any kind of pollution such as water, air, or noise pollution ("Solar Energy." Latent) (David).This friendly energy could help to prevent many diseases. However, the fossil fuel that the world depends on is polluting the environment. Fossil fuel makes most kind of pollutions in the world besides the global worming which causes the flows and tide waves ("Solar Energy.", Howard). These hazards will shrink be using solar energy. .
Another advantage of solar energy is the infinite production of energy (David). Unlike fossil fuels, solar energy is on hand just about everywhere on earth. As a result, solar energy is particularly useful where there are no people such as remote site water pumping or in space. Also, by the time, fossil fuels will be over used with the increasing in the world population, so solar energy will be the future of the future (Block). .
However, the collectors do not use all the energy of the sun because what reach the earth is little comparing to the huge amount of energy in the sunlight. While some of the energy is lost in the space and some evaporates water, the rest is used by the collectors" devices ("Solar Energy." Latent). By the solar energy, we can solve the dilemma of balancing between the concern about our environment safety and the urgency of using energy.
There are disadvantages that need to be mentioned in order to keep a balanced perspective of solar energy's uses, which require a necessary amount of sunlight that is dependant upon the location of the sun, the time of day and the seasons.
