  • We manufacture modules with area efficiency of 15-16.5%.
  • We provide best performance among peers at lowest light intensity.
  • Our modules have low temperature coefficient facilitate operations at high temperature and humidity regions.
  • Our modules certified for use at high and low temperatures (-40 to +85 degrees).
  • Superior durability modules have passed 3000 hours of Damp Heat Tests.
  • We are the first Indian manufacturer to identify and incorporate changes in manufacturing processes in order to reduce Potential Induced Degradation (PID) at module level.
  • Modules manufactured with cells from narrow Impp bins which ensure optimal performance at string level. Modules made with optimal shunt resistance cells for superior hot spot resistance.
  • We comply with IEC 61215 (quality and design), IEC 61730 (safety) and IEC 61701 (salt mist corrosion), and MNRE (ELDORA 3 to ELDORA 280), UL 1703 & MCS (ELDORA 140 to ELDORA 280), CEC, BS OHSAS 18001:2007, ISO 9001:2008, ISO 14001:2004.
  • We promise high reliability with guaranteed 0 to +4.99 Wp positive power output tolerance, ensuring faster return on investment (ROI).
  • Our modules withstand very high wind-pressure and snow load (passed 5400 Pa mechanical loading test as per IEC standard).


  • Cell Testing: The preliminary step in module assembly involves testing the individual photovoltaic cells automatically for their electrical parameters.
  • Stringing: Setting up electrical connections between strings of solar photovoltaic cells involves the stringing process. Cells are stringed together using automated stringing equipment employing pre-programmable software.
  • Bushing: This step involves linking the cell strings in a series, parallel, with bus ribbons, in order to give the required shape to the module prior to encapsulation.
  • Lay-Up: The laminating materials are laid up in a particular sequence and certain characteristics are measured with electronic equipment.
  • Lamination: The interconnected solar PV cells are laminated with clear polymer-like material. This is followed by trimming where the excess polymer sheet is trimmed off from the edge with the help of a heated knife.
  • Framing: The laminated PV cells are enclosed in an aluminum frame with a glass in front.
  • Fixing a junction box and connection cables to rear side of each polycrystalline solar module follows. This enables easy electrical integration among modules in the installation site.

At Vikram Solar, every single module undergoes a stringent quality testing procedure so as to ensure the highest standards in our products. Besides complying with various internationally recognized quality standards, including ISO 9001-2008, we have obtained TUV safety class, UL and CE certifications for our PV modules. Expanding its base from India, within a span of four years, VIKRAM SOLAR has made a name for itself in the international solar PV module market including North America, Europe and Africa.
