The main advantages of solar energy are reliability, predictability, continuity, low maintenance, no cost, no pollution and good performance. Solar energy can be used directly for water heating, lighting, cooking, passive heating, charging portable devices, attic ventilation, inverter and cooling.

What is a Mcq solar cell? Explanation: The p-n junction that created the EMF when solar radiation falls on it is called the solar cell. The material used to make the solar cell should have a band gap of about 1.5 eV. 2.

How many types of solar cells are there in Mcq?

Explanation: There are three types of solar cells. Single-crystal, polycrystalline and amorphous silicon cells are the main types of solar cells.

How many types of solar cells are there?

Solar cells can be divided into three broad types, thin-film crystalline silicon-based solar cells, and a recent development that is a mixture of the other two.

How many layers do solar cells consist of MCQ?

It consists of two separate layers (p-type and n-type – see Figure 3) and is what actually converts solar energy into usable electricity through a process called the photovoltaic effect (see below). On both sides of the semiconductor is a layer of conductive material that “collects” the electricity produced.

What are the main advantages of solar cells?

Solar energy is free of pollution and does not cause greenhouse gas emissions after installation. Reduced dependence on foreign oil and fossil fuels. Renewable clean energy available every day of the year, even cloudy days produce some energy.

What are the two advantages and disadvantages of solar cells?

(i) Solar cells convert solar radiation directly into electricity. (ii) Solar cells are particularly cost-effective in remote areas where the cost of installing other energy methods is very high. (iii) Solar cells have no moving parts and are therefore maintenance-free.

What are the advantages of solar cells?

Advantages or advantages of a solar cell âž¨It is very easy to operate compared to other renewable energy sources. âž¨Does not cause noise as it has no moving parts. âž¨Does not generate emissions or radiation. âž¨ It does not need fuel or water to produce electricity.

What are 5 advantages of solar energy?

What are the two uses of solar energy?

Solar energy is used today in a number of ways:

Like heat to make hot water, heat buildings and cook.
To generate electricity by solar cells or heat engines.
Remove the salt from seawater.
Use sunlight to dry clothes and towels.
It is used by plants for the process of photosynthesis.

What are the uses of solar energy? Solar energy is often used for solar water heaters and home heating. The heat from solar ponds enables the production of chemicals, food, textiles, hot greenhouses, swimming pools and livestock buildings. Cooking and providing an energy source for electronic appliances can also be achieved using solar energy.

Why is solar energy bad?

Solar energy systems / power plants do not produce air pollution or greenhouse gases. … Some solar thermal systems use potentially hazardous fluids to transmit heat. Leaks from these materials could be harmful to the environment. U.S. environmental laws regulate the use and disposal of these types of materials.

What are the negative effects of solar energy? The environmental impacts associated with solar energy are land and water use and pollution, habitat loss, and use of highly hazardous materials in the production process.

What are the advantages and disadvantages of wind energy?

Advantages of wind energy	Disadvantages of wind power
Renewable & amp; a pure source of energy	Intermittent
Low operating costs	Noise and visual pollution
Effective use of land space	Some adverse environmental impact

What are 5 advantages of wind power? Wind energy The most efficient technology to produce energy in a safe and environmentally sustainable way: it is zero emission, local, inexhaustible, competitive and it creates wealth and jobs.

What are the disadvantages of wind energy?

Turbines could cause noise and aesthetic pollution. Although wind farms have relatively little impact on the environment compared to conventional power plants, care exists over the noise produced by the turbine blades and visual effects on the landscape.

What is an advantage of solar energy?

Solar energy is pollution-free and causes no greenhouse gases to be emitted after installation. Reduced dependence on foreign oil and fossil fuels. Renewing clean power available every day of the year, even cloudy days produce some power. Return on investment as opposed to payment for utilities.

How solar energy is beneficial for the environment?

The environmental benefit of solar energy Solar energy creates clean, renewable power from the sun and benefits the environment. Alternatives to fossil fuels reduce carbon footprint at home and abroad, reducing greenhouse gases around the world. Solar can have a favorable effect on the environment.

What is the main advantage of solar energy? Solar energy is pollution-free and causes no greenhouse gases to be emitted after installation. Reduced dependence on foreign oil and fossil fuels. Renewing clean power available every day of the year, even cloudy days produce some power.

What are 2 positive effects of solar energy on the environment?

The Positive Effect of Solar Energy on the Environment Solar energy systems derive clean, clean energy from the sun. Installing solar panels on your home helps combat greenhouse gases and reduces our collective dependence on fossil fuel.

What are positive effects of solar energy?

Solar energy reduces greenhouse gas emissions With solar, you can reduce the demand for fossil fuels, limit greenhouse gas emissions and reduce your own carbon footprint. In fact, only one home installing a solar energy system has a measurable impact on the environment.
