Answer to Question 1

Monocrystalline silicon panels, advantage: most prevalent bulk silicon material. Disadvantage: must be cut from a larger silicon cylindrical ingots.

Bifacial monocrystalline panels, advantages : converts light into electrical power from both sides of the panel. Disadvantages requires special mounting and reflectors to get the light to both sides of the panel.

Polycrystalline silicon panels, advantages less expensive to manufacture than monocrystalline panels. Disadvantages less efficient than monocrystalline panels.

String ribbon panels, advantages lower production cost to less waste. Disadvantages lower efficiencies than the polycrystalline silicon.

Amorphous silicon thin film panels, advantage of thin film panels is low manufacturing cost and versatility. This advantages lowest efficiency of any other current photovoltaic technology.

Cadmium telluride panels advantages: very efficient light absorbing material for the thin-film cells and large-scale cells. Disadvantages cadmium is toxic with about the same amount of cadmium as a NiCad battery.

Answer to Question 2

The parabolic trough generating system consists of large solar reflectors with piping running through the middle of them. The fluid flows through the piping that continually picks up heat energy from the solar energy. A heat exchanger allows the fluid to heat water in a second loop until it reaches steam which is used to move a typical electrical generating turbine. At night or when the fluid flowing through the piping becomes too cool to produce steam, and alternative energy such as natural gas issues to heat the water to steam.

Wow, this really help

 

Did you know?

Though Candida and Aspergillus species are the most common fungal pathogens causing invasive fungal disease in the immunocompromised, infections due to previously uncommon hyaline and dematiaceous filamentous fungi are occurring more often today. Rare fungal infections, once accurately diagnosed, may require surgical debridement, immunotherapy, and newer antifungals used singly or in combination with older antifungals, on a case-by-case basis.

The National Institutes of Health have supported research into acupuncture. This has shown that acupuncture significantly reduced pain associated with osteoarthritis of the knee, when used as a complement to conventional therapies.

There are actually 60 minerals, 16 vitamins, 12 essential amino acids, and three essential fatty acids that your body needs every day.

Did you know?

Vaccines cause herd immunity. If the majority of people in a community have been vaccinated against a disease, an unvaccinated person is less likely to get the disease since others are less likely to become sick from it and spread the disease.

Did you know?

Asthma-like symptoms were first recorded about 3,500 years ago in Egypt. The first manuscript specifically written about asthma was in the year 1190, describing a condition characterized by sudden breathlessness. The treatments listed in this manuscript include chicken soup, herbs, and sexual abstinence.
