The energy collected is about 2.5 and 1.4 times higher than standard collectors in winter and spring.
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 Earth revolves around the sun in an elliptical orbit and is closer to the sun during part of the year. When the sun is nearer the Earth, the Earth''s surface receives a little more solar energy. The Earth is nearer the sun when it is summer in the southern hemisphere and winter in the northern hemisphere.
Earth''s energy budget (or Earth''s energy balance) is the balance between the energy that Earth receives from the Sun and the energy the Earth loses back into outer space. Smaller energy sources, such as Earth''s internal heat, are taken …

It is apparent that the total amount of solar energy received by a collector on the surface of the Earth during a day or during a year depends on several factors, most important of which are: 1. The geographic latitude of the location of the collector. 2. The average cloudiness or coverage of the location. 3. The day of the year. 4.

Parabolic troughs, dishes and towers described in this section are used almost exclusively in solar power generating stations or for research purposes. Parabolic troughs have been used for some commercial solar air conditioning systems. Although simple, these solar concentrators are quite far from the theoretical maximum concentration. For example, the parabolic trough concentration is a…
Flat-plate collectors are the most common and widely used type of solar thermal collectors. They consist of a flat, insulated box with a dark absorber plate covered by a transparent glass or plastic cover. The sunlight passes through the transparent cover and is absorbed by the plate, which heats up and transfers the heat to a fluid flowing through tubes or …

Renewable energy technologies produce marketable energy by converting natural phenomena and sources of energy into useful forms of energy. These technologies use the sun''s energy and its direct (solar radiation) and indirect effects on the earth (wind, falling water, and various plants, i.e., biomass), gravitational forces (tides), and the heat of the earth''s …

The Energy Collector is the first tier of Energy Collectors from Equivalent Exchange 2. It is used to convert light to EMC, and upgrade fuels (see Usage). If it is not upgrading fuels, it will export its EMC to an adjacent device, such as an Energy Condenser or Anti-Matter Relay. It can be upgraded into the Collector MK2. The Energy Collector is not limited to sunlight. It has an EMC …

The absorbed energy may also be emitted back toward Earth, where it will warm the surface even more. Adding more components that absorb radiation – like greenhouse gases – or removing those that reflect it – like aerosols – throws off Earth''s energy balance and causes more energy to be absorbed by Earth instead of escaping into space.
