This document discusses different methods of harnessing solar energy, including:
- Solar thermal systems use collectors to heat a fluid that is then used for water heating or generating electricity in solar thermal power plants.
- Photovoltaic (PV) panels directly convert sunlight into electricity using solar cells made of semiconductors. When light hits the cells, it creates an electric current.
- Concentrated solar power plants focus sunlight using mirrors or lenses to heat a receiver and produce steam to drive turbines for electricity generation.

Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis. It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power.

Solar thermal power generation systems use mirrors to collect sunlight and produce steam by solar heat to drive turbines for generating power. This system generates power by rotating turbines like thermal and nuclear power plants, and therefore, is suitable for large-scale power generation.
A solar power plant is based on the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses, mirrors, and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics converts light into electric current using the photoelectric effect. The largest photovoltaic power plant in the world was the 354 MW Solar Energy Generating Systems (SEGS) CSP installation located in the Mojave Desert, California. But now the largest is in india, India owns world's largest solar power plant - Believe it or not | The Economic ... Other large CSP plants include the 250 MW Agua Caliente Solar Project in Arizona, the Solnova Solar Power Station (150 MW, 250 MW when finished) and the Andasol solar power station (150 MW), both in Spain.
Concentrated solar power plants first appeared in the 1980s. Solar power is increasingly used.
In spite of the high cost of solar technologies and policy of government, investment in the solar power generation is the good pay off due to the noise free and pollution free solar energy.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2. • The sun is a star
• Source of energy in
the sun is at its core
• This energy is released
into space primarily as
electromagnetic
radiation
• We experience this
radiation as heat and
light
The Sun
3. • Every hour enough sunlight
energy reaches the earth to meet
the world’s energy demand
for a whole year
• South Africa
represents the spot of
highest solar insulation

How Powerful is Solar Energy?
4. .
Three main uses:
• Heating of water
• Solar thermal
power stations
• Photovoltaic panels
Uses for Solar
Energy
5. • Indirect system: heat
transfer fluid moves heat
from solar collector to tank
• Direct solar system:
heats water directly
Water in direct system
circulated in two ways:
• Active system: pumps
heated water from collector
to solar storage tank
• Passive system:
no pump - thermosiphon
• Two types of
solar collectors:
- Flat panel
- Evacuated Tube system
Solar Water Heating
6. Solar Flat Panel
• Glass-covered
framework
• Inside a series of
copper tubes with
copper fins attached
• Entire structure
coated in
black substance
designed to capture
the sun’s rays
• Rays heat water,
which circulates
from the collector to
an isolated tank
7. • Multiple evacuated glass
tubes with solar absorbers
collect heat energy from sun
• Absorber inside vacuum
tube absorbs radiation from
sun and heats up fluid inside
the copper pipe
• Additional radiation is
picked up from reflector
behind tube
• Effective whatever the
angle of the sun – even on a
cloudy day
Evacuated Tube System
8. • Used in
Concentrated Solar
Thermal
Power Plants (CSP)
• Solar energy
is concentrated to

a. Parabolic Trough
b. Fresnel
c. Parabolic Dish
d. Central Receiver

9. Concentrated Solar Thermal Power Plants
Converting Solar Energy (Heat) into Electricity
• A solar thermal
power plant converts
solar energy into
electricity
• The temperature in
a concentrated solar
power station is high
enough to produce
steam
• The steam is fed
into a turbine which
generates electricity
10.
11. Photovoltaic
Effect
• Converting
solar energy to
electrical energy by
means of solar cells =
photovoltaic effect
• Photovoltaic panel
consists of a group of
solar cells
• Solar cells are
predominantly made
from silicon, a
semiconductor
12. • PV panels consist of
semiconductors
• PV cells have two types
of semiconductors: one
positively charged and
one negatively charged
• When light shines on
the semiconductor, the
electric field across the
junction between these
two layers causes an
electric current
• The greater the
intensity of light, the
greater the flow of
electricity.
