PORTUGAL, FEBRUARY 2010
World Energetic Consumption
Source:
Internacional
Energy
Agency
79,5% of the energy used by humans came from
fossil fuels in 2000
•Solar energy is the
energy derived from the
sun through the form of
solar radiation.
•Solar powered
electrical generation
relies on photovoltaics
and heat energies.
Concepts
TYPES OF SOLAR PANELS
Monocrystalline Solar
Panels:
- Made from a large crystal
of silicon
- Most efficient, more
expensive
Polycrystalline Solar
Panels:
- The most common, less
expensive
- it consists of multiple
amounts of smaller silicon
crystals
SOLAR TECHNOLOGIES
ACTIVE SOLAR
– use photovoltaic
panels, pumps &
solar thermal
collectors
- purpose: converting
sunlight into energy
& increasing the
supply – supply
technologies
PASSIVE SOLAR
- Include selecting
materials with thermal
properties, designing
spaces and buildings
- purpose: reducing
the need for
alternative resources
- demand
technologies
APPLICATIONS OF SOLAR
TECHNOLOGY
Architecture and urban planning
Agriculture and horticulture
Solar lighting
Solar thermal
Electrical generation
• Passive solar architecture oriented relative to the sun
• greenhouses
• Daylighting systems
• Hybrid solar lighting
• Water heating
• Heating, cooling, ventilation
• Photovoltaics (PV)
• Concentrating solar power (CSP)
FUTURE TRENDS • POSITIVE
- Experts estimate the sun’s ability to produce 10,000 times as much energy as the Earth produces
- preoccupation and extensive research in this area
• 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
- ´20 20 20´ EC strategy.
- Solar thermal power industry will grow from 1,2 GW in 2009 to 14 GW in 2014
What can WE do?
• In spite of all the progress, the future of
energy lies in our own hands and actions:
installing solar panels
donating to research organizations in the
field
studying science or engineering
voting for measures directed to alternative
energy development
Solar energy in Romania
Romania’s climate : 210 sunny
days/year & 1250 kWh/ m² of solar
radiation
The most important solar
regions: Black Sea coast, Dobrogea
and Oltenia
In process, solar plant construction projects – Covaci Solar Park (480 000 solar panals
and 35 MW capacity
Solar energy in Greece
The second biggest market in UE in solar
collectors
Applications used almost
exclusively for water heating
Smaller importance of photovoltaic applications (capacity of 332 kWp in
2000)
Solar energy in Spain
New laws for civil
construction has developed
the solar energy
Public grants from regional and national government
helping citizens to set
up panels
Different situation into
the isles due to the isolation of electric grids
Solar energy in Poland
1000 W/m² solar
radiation per year
Investment into solar panels will
paid off after 8 years
Now we have 5% renewable energy and by 2020 we need
15%
