Photovoltaic modules (PV modules / Solar Panel)use light energy (photons) from the Sun to generate electricity through the photovoltaic effect. The majority of modules use wafer-based crystalline silicon cells or thin-film cells. The structural (load carrying) member of a module can either be the top layer or the back layer. Cells must also be protected from mechanical damage and moisture. Most modules are rigid, but semi-flexible ones are available, based on thin-film cells. The cells must be connected electrically in series, one to another. Externally, most of photovoltaic modules use MC4 connectors type to facilitate easy weatherproof connections to the rest of the system.
Solar Panel in Pakistan
There are too many low quality brand available in Pakistan. These brands are cheap and life is too less as compare to top brands solar panels. Those have 4-5 years of life expectancy and after that You will again experiencing the market. The endorsement of net-metering — which enables top solar panels buyers to offer power they create to the national grid — is a noteworthy leap forward that could goad utilization of energy enable Pakistan’s administration to cut power deficiencies over the long haul.
Numerous non-marked and imported solar panel possess 70% of the market. These items have generally decreased costs and have all inclusive perceived TUV affirmation which guarantees that their items are globally worthy for wellbeing and quality.
Here are top quality Solar panels which we supply in Pakistan
Hanwaha Q-CELLS, Jinko solar, Trina Solar, Yingli, Talesun suitable for better performance , suitable for net metering and longer life.
Modules Solar panels electrical connections are made in series to achieve a desired output voltage and/or in parallel to provide a desired current capability. The conducting wires that take the current off the modules may contain silver, copper or other non-magnetic conductive transition metals. Bypass diodes may be incorporated or used externally, in case of partial module shading, to maximize the output of module sections still illuminated.
Some special solar PV modules include concentrators in which light is focused by lenses or mirrors onto smaller cells. This enables the use of cells with a high cost per unit area (such as gallium arsenide) in a cost-effective way.
