It is a pleasure to officially announce that Su-Kam Power Systems Limited has recently bagged a 1MW solar project that will drive Chennai Rail Metro this year.

Chennai Rail Metro Limited’s corporate office located in Poonamallee High Road, Koyambedu, Chennai, offered the project of installing 1MW solar on-grid system to Su-Kam Power Systems Limited. It is expected to generate approximately 1,50,000 units of electricity every month.

Project Details and Specifications

The Chennai Rail Metro Limited has planned to install 8MW solar on-grid plant in various locations to run the Chennai Metro fully on solar every single day. The very first installation was of 1MW rating that required an installation of Su-Kam’s grid-tie inverters that would run the metro load on solar during the day and feed the excess solar power back to the Tangedco grid, thus making full use of the installed solar plant.

The system has been specially designed to run the full load with the grid tie inverters working on maximum allowable tariff rating of 5.32 per unit.

Mr. Devender (Su-Kam’s solar project business head) and Venkat Kanna (Assistant manager, solar projects) have been working very hard to make sure that the project sees the light of day. The following were the specifications of the solar system –

Technical Specifications:

  1. Solar panels 315W (1600 in number), 310W (1600 in number)
  2. Grid-tie inverters – 50KW (20 in number)

Units Generated and Savings

As mentioned before, the system is expected to generate 4500 units of electricity daily every day that will greatly help in reducing carbon emissions down to 1500 tons per year. How did I calculate this? Well, without getting into technical details, we can calculate the reduction of carbon emission by keeping in mind a simple thumb rule (Applicable to Indian weather conditions) – A 1KW Solar system will approximately help in reducing 1.5 tons of carbon emissions per year.

That is if you use fossil fuel based electricity generation instead of a solar plant. Of course this number also depends on weather conditions and so this is a rough estimate. But we can sure get an idea.

This massive installation is going to make a major difference in reducing carbon emissions in India per year. Please follow Su-Kam’s official blog to know the final outcome of the installation and more.
