Did you know it?
 


Photovoltaic energy is measured in Wp « watt peek », thus the power of your solar energy production system will be likewise
      expressed.

Calibration of the power of a solar cell or panel is usually done under standard test conditions : sunlight = 1000 Watts/m², air mass = 1.5 and temperature = 25°C

Direct and alternating current: from sunlight, your solar energy production system will produce electricity under its direct current form. In order to be able to use it for your household equipment needs, it will have to be converted by a current inverter, which will transform it
      into alternating current. It may be
      possible to use direct current as produced
      by solar cells without transformation,
      provided it is received by compliant
      equipment.

 



 


Why use solar energy?

In 2006, 86.5% of the world's energy consumption was based on fossil combustible energy sources. At this rate, they are extracted and used 100 000 times faster than it takes to generate them. The remaining13.5% were sustained by the use of renewable energy sources such as biomass (3/4 of the need).
Renewable energies provide for 18 % of the world's electrical production. In the European Union (with 25 countries), they cover 14% of all electrical needs. Over the world, renewable electricity production is mainly provided by hydro-electrical plants (90%), biomass (5.6%), wind energy (3%), geothermal energy (1.7%) and solar energy (0.1%).
In addition to the fact that solar energy seems inexhaustible, it does not contribute to the greenhouse effect phenomenon. It clearly appears that solar energy holds a great potential for the future of renewable energy sources.

 
Although technologies necessary to convert sunlight into electrical power (solar panels) are widely mastered, solar energy is under exploited. As a response to this huge market potential, industries are concentrating their innovative efforts not only on the variety of solar energy related products (flexible thin-film solar cells, high resistance panels, solar air conditioning), but also on new possible ways to use and benefit from solar energy through Building Integrated Photovoltaic (BIPV) solutions.
In France, a bill passed in March 2002 insures all private owners of photovoltaic systems to be able to sell their electrical production by re-injecting it into the public electrical power supply network. The public electrical power provider is to purchase this electrical production for 20 years at a fixed price. The fixed purchase rate is updated on a yearly basis.

In 2006, the latest revision of the fixed purchase rate for privately produced and re-injected electricity through solar panels installations was brought to 30 cents (Euros) / kWh. An additional incentive of 25 cents / kWh is provided for re-injected electricity produced through BIPV systems.

Over the French overseas regions and territories, the purchase rate is 40 cents (Euros) / kWh, with an additional incentive of 15 cents for BIPV systems produced electricity. Moreover, specific government incentives and fiscal regulations participate in creating the perfect environment for solar systems installations.

JSA Technology wishes to be a key player in the popularization of these technologies for the benefit of our planet

From light to electricity
Every day, the earth receives through solar energy the equivalent of the electric consumption for 5.9 billion persons during 27 years.
Photovoltaic technologies allow conversion of this energy into useful electricity.
This transformation is noiseless and green house gas emission free: thus totally clean by nature.
Besides, the absence of mechanical parts in solar energy production systems confers them a long life cycle (average life cycle of a solar panel is estimated at 30 years).

Industrial applications
Photovoltaic modules are distinguished by the type of silicon technology they use  

Monocrystallin silicon
silicon crystals are encapsulated inside plastic cells that have a high resistance to sun ray exposure. They form photovoltaic panels with long term resistance to weather conditions and high-performance electrical production capabilities.

Polycrystallin silicon
these have a lower efficiency level as they are made of a variety of silicon crystals mainly originating from recycling of electronic quality silicon parts.

Amorph silicon
manufacturing process of these photovoltaic panels consists in pulverising silicon on a prepared surface, such as to get a very flexible, durable high-performance solar cell or panel. This product is a must in BIPV (Building Integrated Photovoltaic)

Types of applications
- Grid connected solar systems
- Stand alone solar systems
