Engineering & Technology Partner- Sunlink Corp. USA Joined hands with Sunlink to bring best Single Axis Tracking solution in India Engineering & Technology Partner- Sunlink Corp. USA Executed more then 2 Gigawatt of Solar PV projects. Developed solar solution for 1GW of projects across USA. Expertise in delivering premium product at a market-leading price Supplied more than 1450 MW of Module Mounting Structures

Why to track sun Energy produced by solar energy system is directly proportional to the incident radiation falling on the modules Sunlight’s "direct beam" carries about 90% of the solar energy Trackers have accuracies of ± 5° can deliver greater than 99.6% of the energy delivered by the direct beam plus 100% of the diffuse light (indirect light). Module efficiency is 14% to 18%, which means only 14-18% of incident light is convertible to useful energy Tracking helps to compensate for the variation in solar radiation due to rotation

Tracking Ideology Tracking increases power generation by 15%- 25% over fixed tilt per DC Watt peak. Initial capex increase will be 8% to 10% of project cost per DC Watt peak. For generation equal to fixed tilt per Watt peak tracking reduces capex by 6% to 8%.

Points to remember while selecting Tracker Tracker parts should be easily available off the shelves. Trackers should be tested for high wind and high snow zones. Tracker should be compatible with irregular & challenging sites. Tracker helps in higher unit generation Units Generated / KWp Deviation in % Fixed Tilt 1685 Seasonal Tracking 1759 4.4% Single Axis Tracking 2008 19.2%

Solar Tracker Solution Innovative tracker system helping in maximizing energy production by providing 15-20% additional power Centralized drive capitalizes on proven hydraulic technology and simplifies the mechanics and maintenance of single axis trackers

Why to choose GIPL tracker GIPL tracker has centralized drive capitalizes on proven hydraulic technology which simplifies the mechanics and maintenance of single axis tracker. Centralized drive means fewer components, therefore less points of failure Utilizing standard hydraulic technology worldwide Adaptable design over a range of environmental conditions Utilize Industrial grade components to design the system Integrated grounding per immediate layout. ETL listed to the UL2703 standard

Tracker savings For Example: To generate 20MW of energy Fixed tilt Capex is = 96.8 Cr (@ Rs. 4.84 Cr.) Single Axis tracker you just need to install only 16.84 MW @ capex of 90.94 Cr. (@ Rs. 5.40 Cr.) Shows Capex is reduced by 6.16 Cr. (6.05 %) O&M for a 20 MW plant can be done @ Rs. 50,000 /MW/Year including spares and consumables. Revenue increase per MW for this site would be 3.2 Lacs KWh @ Rs. 4.95 which works out to Rs. 15.8 Lacs/anum. O&M cost is just 3.1 % of the extra revenue generated.
