Attempt all the questions:
Q1. What is solar
photovoltaic technology? Discuss its underlying principle and applications.
Solar
photovoltaic (PV) technology is a method of converting sunlight into
electricity using semiconducting materials. It is a sustainable and renewable
energy source that harnesses the abundant energy from the sun and converts it
into usable electrical power.
The basic
principle behind solar PV technology is the photovoltaic effect, which was
first discovered by Alexandre-Edmond Becquerel in 1839. The photovoltaic effect
occurs when certain materials called semiconductors absorb photons (light
particles) from sunlight. This absorption generates an electric current within
the material.
The key
component of a solar PV system is the solar cell, which is typically made of
silicon. When photons from sunlight strike the silicon atoms within the solar
cell, they transfer their energy to the electrons in the silicon atoms, causing
them to become excited and break free from their atomic bonds. These free
electrons create an electric current when they flow through the material. By
connecting multiple solar cells together, the electric current generated by
each cell can be combined to produce a larger amount of electricity.
Solar Panels:
Solar panels, also known as photovoltaic modules, consist of multiple solar
cells connected together. These panels are usually mounted on rooftops or in
open spaces to capture sunlight.
Inverter: The
direct current (DC) electricity produced by the solar panels needs to be
converted into alternating current (AC) electricity, which is the type of
electricity used in most households and businesses. An inverter is used to
perform this conversion.
Mounting
Structure: Solar panels need to be securely mounted in a position that
maximizes their exposure to sunlight. Mounting structures can vary depending on
the location and type of installation.
Wiring and
Connectors: Wiring and connectors are used to connect the solar panels to the
inverter and other components of the system.
Battery
(optional): In some off-grid or hybrid solar PV systems, batteries are used to
store excess electricity generated during sunny periods for use during times
when sunlight is not available.
Residential
Solar Power: Solar PV systems can be installed on residential rooftops to
provide electricity for homes. This reduces dependence on traditional grid
electricity and can lead to significant cost savings over time.
Commercial and
Industrial Applications: Many commercial and industrial buildings use solar PV
systems to generate electricity for their operations. This can help businesses
reduce their energy costs and decrease their carbon footprint.
Utility-Scale
Solar Power Plants: Large-scale solar power plants, consisting of thousands of
solar panels, are built in sunny regions to generate electricity on a massive
scale. These solar farms can provide clean energy to thousands of homes and
businesses.
Remote Power
Systems: Solar PV systems are ideal for providing electricity in remote areas
where grid power is unavailable or impractical. They are commonly used to power
telecommunications equipment, remote monitoring stations, and off-grid homes.
Solar-Powered
Vehicles: Solar PV technology is also being integrated into vehicles, including
cars, boats, and drones, to provide supplementary power and extend their range.
Overall, solar
PV technology offers a clean, renewable, and sustainable source of electricity
with a wide range of applications across residential, commercial, industrial,
and remote settings. As technology advances and costs continue to decrease,
solar PV is becoming an increasingly important part of the global energy mix.
Q2. Explain how the
carrying capacity of the Earth can be estimated using various parameters.
Q3. Give a brief
description of the future projection of world energy demand as per EIA
International Energy Outlook2004.
Q4. Discuss the
advantages and limitations of Clean Development Mechanism to help meet the
challenge of combating climate change.
Q5. Discuss the
factors that need to be kept in view while formulating the energy policy.
Q6. What is energy
economics? Explain the factors that need to be considered in energy economics.
Q7. Describe the
positive and negative impacts of the solar energy technology on the environment.
Q8. Discuss the
working of a wind energy system with the help of a suitable diagram.
Q9. Discuss the
advantages and limitations of small hydropower plant.
Q10. Write short notes on the following:
(i) Functions of the components of a thermal
power plant
(ii) Benefits of carbon taxation
(iii) Working of a biogas plant
(iv) Fuel switching
