solar cells

ltd.

photovoltaic cell manufacturer



Since 1987, Solar cells have offered the benefits of photovoltaic modules and plates under trade mark "Microex" - New generation at an affordable price.
Solar cells creates no dangeours waste products.
Solar cells are infinitely renewable and inexhaustible"
solar energy is clean and reliable.
It is non-polluting and environmentally benign.
Solar cells provide an attractive,maintenance-free method to generate electricity reliably.

Put the Power of the Sun to Work for You

These solar cells are constructed from standard photovoltaic product which is an amorphous thin silicon device deposited on a glass substrate.For long-term reliability, we implement a unique process of fully protecting the sillicon layer of solar cells with an additional glass backing;resulted in a 'sandwiched' solar cell encapsulation within glass and UV resin.Solar cells are framed by a polycarbonate extrusion,sealing and protecting the glass edges.This solar cells shall be framed with aluminium profile prepared for fastening on the surface.
Within EPIA - the European Photovoltaic Industry Association-solar energy is not regarded just as an alternative to convertional energy sources.It is regarded as having the potential of becoming the ultimate solution to mankind's energy problem.
MICROEX
Microex solar cells are designed for a variety of applications including utillity interactive power systems,stand-alone generating systems and many small power generating applications.
We use our own Research and Development Laboratories to further our work in this area in cooperation with Institute Rudjer Boskovic in Zagreb.
Explanations & definitions
* Plate product shall be defined as a photovoltaic device on a glass substrate protected with a roller coated film medium
* Modules shall be defined as a photovoltaic device on a glass substrate protected with a glass - to -glass,edge seal and frame encapsulating system.All modules shall be framed with black plastic framing material or aluminium frame.
* The standard test conditions (STC) shall be defined as Insolation = 1000 W/m2,Module Temperature = 25 degrees Centigrade, Air Mass = 1.5 and Wind Speed = (TBA)
* The short circuit current,Isc,is defined as the current when there is no voltage across the load at STC.
* To open circuit voltage,Voc is defined as the voltage when no current is being drawn at STC.
* The specified voltage,Vspec,is the voltage at which the circuit is designed to draw current from the PV device.
* The peak wattage is defined as the product of current and voltage at the peak power point;that is,Wpeak = I peak x V peak at STC
* The System Voltage Max shall be defined as the maximum voltage that a module or plate should be subjected to when connected into a series string -600 V
