Abellon Clean Energy Interview Questions, Process, and Tips

Efficiency is the ability to do something in a way that achieves maximum productivity with minimum wasted effort or expense.

• Efficiency is a measure of how well a system or process performs.

• It is often expressed as a percentage of the total input that is converted into useful output.

• For example, a car's fuel efficiency is measured in miles per gallon (MPG).

• Efficiency can be improved by optimizing processes, reducing was...read more

Latent heat is the heat energy absorbed or released during a phase change without a change in temperature.

• Latent heat is the energy required to change the state of a substance without changing its temperature.

• It is the heat energy absorbed or released during processes like melting, vaporization, and condensation.

• During phase changes, the energy is used to break or form intermolecular bonds.

• Examples include the heat abs...read more

Sensible heat refers to the heat that causes a change in temperature without a change in phase.

• Sensible heat is the heat energy that can be sensed or measured by a thermometer.

• It is the heat that causes a substance to increase or decrease in temperature.

• Sensible heat does not result in a change of state or phase.

• For example, when ice is heated and melts into water, the heat absorbed during this process is sensible heat...read more

Types of losses in a boiler system

• Heat loss through walls and pipes

• Incomplete combustion of fuel

• Blowdown loss

• Radiation loss

• Stack loss

• Excess air loss

Boiler interlock is a safety mechanism that ensures safe operation of a boiler by preventing it from starting or continuing to operate under unsafe conditions.

• Boiler interlock is a safety feature that prevents the boiler from starting or continuing to operate if certain conditions are not met.

• It is designed to protect the boiler and the surrounding environment from potential hazards.

• Examples of interlocks include low w...read more

Turbine rolling procedure is a process of rotating the turbine shaft to check its alignment and balance.

• Before rolling the turbine, ensure that all the valves are closed and the system is depressurized.

• Start the rolling process slowly and gradually increase the speed to the rated speed.

• Monitor the vibration levels and adjust the speed accordingly.

• Stop the rolling process if any abnormal vibration or noise is observed.

• A...read more

The policy of solar rooftop systems refers to the guidelines and regulations set by governments or organizations to promote the installation and usage of solar panels on rooftops.

• Solar rooftop system policies vary by country and region.

• These policies often include financial incentives such as tax credits or feed-in tariffs to encourage adoption.

• Some policies may require net metering, allowing excess energy generated by...read more

To sell solar systems at the best price without offering a discount, focus on highlighting the long-term cost savings, quality and reliability of the system, and any additional benefits or incentives.

• Emphasize the long-term cost savings of solar energy compared to traditional energy sources.

• Highlight the quality and reliability of the solar system, showcasing any certifications or warranties.

• Discuss any additional bene...read more

The most common fault in rooftop solar systems is panel degradation. Regular maintenance and monitoring can help minimize the time taken to address this fault.

• Panel degradation is a common fault in rooftop solar systems.

• Regular maintenance and monitoring can help identify and address this fault.

• Cleaning the panels regularly to remove dirt and debris can prevent degradation.

• Checking for any loose connections or damaged ...read more

In AC systems, less voltage is considered high, while in DC systems, less voltage is considered low.

• In AC systems, high voltage is typically 220V or 440V, while low voltage is around 110V.

• In DC systems, high voltage is typically 1000V or more, while low voltage is around 12V or 24V.

• AC systems use transformers to step up or step down voltage, while DC systems use converters or inverters to regulate voltage.

The efficiency of an inverter refers to its ability to convert DC power from solar panels into AC power for use in homes or businesses.

• Inverter efficiency is typically expressed as a percentage, with higher percentages indicating greater efficiency.

• Efficiency can vary depending on the type and quality of the inverter.

• Higher efficiency inverters can maximize the amount of electricity generated by solar panels.

• Efficiency...read more
