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%
