Colector solar

Solar collector.

.

Can provide energy without any pollution as fuel or engage in industrial processes, energy demands are greater each day and the optimal functioning of these systems is ofgreat importance. The solar collectors deliver heat energy supply to the re routing of the sun over its entire focal line of the cylinder, increasing temperatures above 400C, the fluid passes.
There aremany types of collectors and are the cylindrical parabolic or spherical type, is of great importance to consider installation in open areas where the incidence solar advantage is largely clear ofobstacles during the transition, consider a minimum distance between collectors. They must be installed overlooking north-south which maximizes the solar day.

3.2 Advantages and disadvantages.Advantages
It is clean energy.
Comes from an inexhaustible source of energy.
Is an energy harvesting system suitable for areas where power lines do not get (field, islands) or is difficult and costly totransfer (it more than 5 Km).
Solar collection systems are easy to maintain.
The cost decreases as technology moves forward (fuel cost increases over time because fewer and fewer).

DisadvantagesThe radiation level varies from one area to another and from one season to another, in our area varies by 20% from summer to winter).
To collect solar energy on a large scale require large tractsof land.
Requires large initial investment.
It should complement this method of converting energy with others.
Places where there is more radiation, are desert and remote locations, (energy notused to develop agricultural or industrial activity, etc.)..
3.3 Automation parabolic.
It is necessary to control self-positioning systems, to obtain a better use by concentrating rays, allowing crosstheir focal point of the cylinder, since the sun's movement must be constant on the panel. (Earth travels at a speed of 29.5 kilometers per second, traveling 106,000 miles an hour, or 2,544,000...
