Solar System in Pakistan
Electricity Crises have covered whole Pakistan from beginning. Increasing day by day. To meet power (Electricity) needs solar energy is playing a vital role. Govt of Pakistan also contributing in solar demand by removing all kind of taxes and duties. Now price of solar in Pakistan is same as price in China as most of solar panels in Pakistan are imported from china. Quality of solar panels is also a burning issue. We will discuss further.
Solar panel known as Photovoltaic module or PV module obsorbs sunlight energy (Photons) and produce electricity. One panel consists of many solar cells connected in parallel or series to get desire voltages and amperes. Every PV module has junction box on back side of panel which is allows it to connect to system. PV modules are enclosed in aluminium frames for safety and durability. Tempered glass is on top which makes it more strong and defends in extreme weather conditions.
Types of Solar Panel in Pakistan:

- Mono Crystalline
- Poly Crystalline
- Thin Film
Mono crystalline solar panels are black in appearance and have diamond shaped white spots between cells. or you can say their corners are cut to make that shape.These cells are made from single silicon crystal, each cell is made separately and then assemble together in a panel. By looking into specifications mono crystalline PV module works better in low temperature. As temperature rises above 40 degree Celsius, their efficiency starts reducing slightly. On 50 Celsius or above they become unstable or efficiency reduces too much. Areas where temperature remains moderate or having cooler environment are suitable for mono crystalline.
In Pakistan areas which are cold or having temperature max of 40 degree Celsius are ideal for Mono crystalline.
- Muree and Other northern areas.
Poly crystalline solar panels are blue in color in appearance. Every cell is square and attached closely to each other.Silicon crystals are melted down into cells and are little easy to make. These panel are little low in cost and works good in high temperature areas. As compared to mono they are less affected by high temperature. In Pakistan high temperature areas are suitable for poly crystalline solar panels.
Thin film panels are totally different in shape and size. Having less efficiency than both Mono and Poly. But it has highest efficiency in high temperature. A panel of 100 watts of this panel is normally the double size of poly or mono panel.
