solar interview questions: 34 Solar Energy Interview Questions (Plus Sample Answers)



In order to be a successful candidate for a position in the solar energy industry, it’s important to know what types of questions will be asked during an interview. We’ve put together a list of 34 Solar Energy Interview Questions (Plus Sample Answers), so that you can prepare yourself before meeting with potential employers.

What is solar energy?

Solar energy is the heat and light from the sun. It can be used for heating, cooling, lighting and powering a variety of electrical devices. Solar panels are used to convert sunlight into electricity that can be used to power homes or businesses.

What are solar cells made of?

Solar cells are made from silicon, a semiconductor material. Most solar panels consist of several individual solar cells that are connected together in series. A single cell has an output of about 0.5-1V and produces around 0.5W at full sun (1kW/m2).

How much sunlight is required to produce 1 kilowatt (kW) of electricity?

The amount of sunlight required to produce 1 kilowatt (kW) of electricity depends on the efficiency of your solar cells. The typical efficiency of solar cells is around 15-20%, which means that it takes about 20 times as much sunlight to produce 1 kW than it would if you were using an efficient light bulb or fluorescent tube. For example, if you had a 100 W incandescent bulb and wanted to replace it with a 5 W CFL, then you would need at least 500 lumens per square foot (lm/ft2) of area illuminated by natural light during daylight hours every day.

Explain the process in which electricity generated by a solar system is transferred to the grid.

The electricity generated by a solar system is transferred to the grid through a meter. The meter measures the amount of electricity generated by your solar panels and sends that information to your utility company, who then charges you for it.

Why are some states more suited for solar energy than others?

The answer to this question depends on what you mean by “suited.” If you’re asking about whether or not solar energy is more effective in some states than others, then the answer is yes. Solar panels are most effective in areas with direct sunlight and less effective in cloudy areas or far from the equator. However, if you’re asking why people choose to live in certain states over others–for example, do they move there because they want access to cheap electricity from coal-fired power plants? Or do they move there because there isn’t much sun but plenty of wind turbines?–then your answer may differ again!

What are the driving forces behind the growth of solar industry in the United States and globally over the next five years?

The growth of solar energy in the United States and globally over the next five years will be driven by several factors:

  • The cost of solar energy continues to decrease as technology improves, making it more accessible to businesses and homeowners.
