The Sun represents the main source of energy for the Earth [].Without the Sun, the temperature on the planet would be in the vicinity of 0 K like in the rest of the interstellar space, making life on Earth impossible [].The diameter of the Sun is 1.39·10 9 m ≈ 1.4·10 6 km and it is situated at about 1.5·10 11 m = 150·10 6 km from Earth [].
The benefits of these types of collector include low cost, no need for solar tracking systems, easy construction and low maintenance costs. FPCs consist a flat plate that absorbs energy to transfer it to a fluid, transparent envelopes to reduce convection and radiation losses, and their surrounding insulates to diminish conduction losses ( Fig ...
Since the last decades, solar energy has been used worldwide to overcome foreign dependency on crude oil and to control the pollution due to a limited source of non-renewable energy.
Solar Water Heating System Maintenance and Repair
Point focus solar collectors, like parabolic dishes, use a big mirror. This mirror concentrates the sun''s energy onto a single point. They work really well at turning sunlight into usable heat, great for green energy uses. Parabolic Dish Design. The design has a curved, mirror-like surface. It reflects the sun''s rays onto a small spot.
