4. Concepts
âąSolar energy is the
energy derived from the
sun through the form of
solar radiation.
âąSolar powered
electrical generation
relies on photovoltaics
and heat energies.
5. TYPES OF SOLAR PANELS
Monocrystalline Solar Polycrystalline Solar
Panels: Panels:
- Made from a large crystal - The most common, less
of silicon expensive
- Most efficient, more - it consists of multiple
expensive amounts of smaller silicon
crystals
6. SOLAR TECHNOLOGIES
ACTIVE SOLAR PASSIVE SOLAR
â use photovoltaic - Include selecting
panels, pumps & materials with thermal
solar thermal properties, designing
collectors spaces and buildings
- purpose: converting - purpose: reducing
sunlight into energy the need for
& increasing the alternative resources
supply â supply - demand
technologies technologies
7. APPLICATIONS OF SOLAR
TECHNOLOGY
Architecture and urban âą Passive solar
architecture oriented
planning relative to the sun
Agriculture and âą greenhouses
horticulture
âą Daylighting systems
Solar lighting âą Hybrid solar lighting
âą Water heating
Solar thermal âą Heating, cooling,
ventilation
âą Photovoltaics (PV)
Electrical generation âą Concentrating solar
power (CSP)
8. FUTURE TRENDS
âą POSITIVE
- Experts estimate the sunâs ability
to produce 10,000 times as much
energy as the Earth produces
- preoccupation and extensive
research in this area
âą NEGATIVE
- the challenge of creating solar
plants because of the restricted
sunny area
- the challenge and expenses of
the constructing new buildings and
refitting old ones
EXPECTATIONS
- ÂŽ20 20 20ÂŽ EC strategy.
- Solar thermal power industry will
grow from 1,2 GW in 2009 to 14
GW in 2014
9. What can WE do?
âą In spite of all the progress, the future of
energy lies in our own hands and actions:
ïŒ installing solar panels
ïŒ donating to research organizations in the
field
ïŒ studying science or engineering
ïŒ voting for measures directed to alternative
energy development
10. Solar energy in Romania
In process, solar
Romaniaâs climate The most plant construction
: 210 sunny important solar projects â Covaci
days/year & 1250 regions: Black Sea Solar Park (480
kWh/ mÂČ of solar coast, Dobrogea 000 solar panals
radiation and Oltenia and 35 MW
capacity
11. Solar energy in Greece
Smaller
importance of
The second Applications
photovoltaic
biggest market used almost
applications
in UE in solar exclusively for
(capacity of
collectors water heating
332 kWp in
2000)
12. Solar energy in Spain
Public grants
New laws for
from regional Different
civil
and national situation into

13. Solar energy in Poland
1000 W/mÂČ Investment Now we have
solar into solar 5% renewable
radiation per panels will energy and by
year paid off after 8 2020 we need
years 15%
