Advantages of Solar Energy

The light from the sun provides a consistent and stable source of energy throughout the year. Unlike other resources which are set to decline in the near future, there several energy sources which are renewable. Eg: Hydropower, biomass, sunlight, wind etc. The benefit of solar energy is its simplicity to deploy with basic setup. Most common source utilize photovoltaic cells to convert sunlight into electricity. They use semi-conductor to absorb radiation from sunlight and emit electrons which will be extracted as electricity.


Advantages of Solar   :

  • Indefinitely renewable (for the foreseeable future)

  • Generate electricity

  • Heating water

  • Sunlight reflectors or skylights reduce energy expenditure required to light rooms during the day

  • Panels also require little maintenance

  • Solar power takes advantage of net metering, which is the practice of crediting homeowners for electricity they produce and return to the power grid

  • Solar energy does not cause pollution

  • Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid

  • Very reliable due to the fact that they actively create electricity in just a few millimeters and do not require any type of mechanical parts that can fail

  • It is estimated that the worlds oil reserves will last for 30 to 40 years

  • Solar energy offers decentralization in most (sunny) locations, meaning self-reliant societies


Grid-connected photovoltaic system is the most common type as they make use of the existing mains electricity grid. They are simpler in design and easier for the installers to fit than off grid systems. The electricity produced during the daytime is either used by the property owner, or directed back into the electricity grid and reduced from our Electricity bill by a utility company, an arrangement called 'net metering'. At night, or on dark days when the panels do not produce sufficient power, electricity will be supplied via normal utility company grid system.


Advantages   :

  1. Export your power back to your utility company under "Net Metering" agreement and reduce your electricity bills.

  2. Most reliable inverters with 5-10 warranty.

  3. No need to maintain battery bank.

  4. Solar panels with up to 25 year performance warranty.

  5. From 1KW upward.


Only Disadvantages   :

  1. No power during power cuts or break downs. (can be overcome by backup system).

Warranty   :

  • 10 Years for on Grid Inverter.

  • 10 Years product Warranty for Solar Panels.

  • 12 Years 90% Performance Warranty.

  • o 25 Years 80% Performance Warrant.

Our On Grid systems start from 0.75kW to 42kW

Vision Solar Energy (Pvt) Ltd is providing Solar Power System Remote Monitoring System to Monitor the Solar Power System Details and Errors. And also Our Customers can monitor their Solar Power System from the Omnik Portal Web Site to know about the profit for their investment.

Omnik Portal

Omnik portal, developed by Omnik New Energy, is a portal site managing power station. It can supply professional solutions of managing power stations for end-uers or distributors. It's convenient to visit the website and look up relevant information of whether small solar home system or large-scale power plants anytime and anyplace. It's also possible for users to make their own web pages, locate power stations, define station capacities, select inverter and panel data.

The basic raw material

Most solar panels produced today are made from Silicon, the second most abundant element on Earth and the primary ingredient in beach sand. The first step in making a solar panel is to create silicon ingots, giant blocks of high-purity (99.999999%) silicon.

To do this, Yingli put hundreds of pounds of silicon chunks (i.e. rocks) into a giant crucible and add a little boron (called a "dopant") to give the silicon positive polarity. Then, we cook it altogether at over 2,000 degrees Fahrenheit.

Ingots & Wafers


Yingli let the large silicon ingot cool down before slicing it into thin wafers using wire saws. Each fresh-cut silicon wafer is less than 200 microns thick - similar to a heavy piece of paper. These wafers must be carefully handled, inspected and cleaned before further processing. The next step is to reduce the reflectivity of the wafer from about 30% to 10% through a chemical surface texturing process that creates tiny pyramids on the wafer's surface. Now, when a photon (sunlight) hits the wafer's surface, it is more likely to be reflected into the wafer rather than back into space.

Making Cells : From "Photo" to "Voltaic"

Solar Panel Assembly

To make a solar panel, Yingly string together 48, 60, or 72 of our solar cells and lay them carefully within an encapsulant, which attaches high-transparency glass on the front surface and a highly durable, polymer-based backsheet on the backside. Then, they warm the whole stack (like a toasted solar sandwich to create a protective cocoon around the solar cells.

Next, for structural stability and long-term protection, they place rigid aluminum frames around the perimeter, bonded together with a waterproof adhesive. Finally, a junction box is added to the back of the solar panel: a connector to facilitate the flow of electricity. Then, the solar panel is ready for quality testing, packaging, and delivery.

Founded in 2001 in Canada, Canadian Solar (NASDAQ: CSIQ) operates as a global energy provider with successful business subsidiaries in 24 countries on 6 continents. With state-of-the-art manufacturing facilities in Canada, China and Vietnam, Canadian Solar employs over 8,900 workers worldwide. This translates into more than 20 GW of panel shipments, or over 70 million PV modules, in the past 15 years. Together with Recurrent Energy, Canadian Solar is ushering the way into a new era of clean, competitive, mainstream power. At Vision Solar Energy (Pvt) Ltd, we use polycrystalline Canadian Solar panels.
