  • Dear Sir,

    You have expressed the concerns rightly.

    We have formed the National Solar Energy Federation of India (NSEFI) which comprises of who's who of the Solar Industry and being headed by Sh. Pranav Mehta (stalwart of Solar Industry) and Sh. Deepak Gupta (Ex- MNRE Secretary).

    We are in continuos discussion with the Govt on enhancing the scope of solar power.

    Kindly let me know your mail id and I shall have the activities of NSEFI mailed.

    Warm Regards
    Anmol

  • As expressed by DrAPJ, it is duty of every Indian to contribute towards energy security of our Nation to make it Strong and really independent strong India 2020.
    Centralized power generation has limitations and problems. The TDL, theft etc are inevitable.
    Rooftop PV or Wind PV hybrid is the best solution for it. this will not only mitigate energy shortage but also suit economy and in long run it is always cheaper than grid power.
    We should form a platform to promote this.
    With regards,

    Dr. OmPrakash G. Kulkarni,
    Mentor, Adviser & Consulting Engineer in

  • 1. ACHIEVING SUSTAINABILITY THROUGH HIGH IMPACT ENERGY EFFICIENCY: SOLAR ROOFTOP ACHIEVING GRID PARITY - Anmol Singh Jaggi
  • 2. Sustainability Economy Sustainability Equity Ecology According to the Webster definition •Involving methods that do not completely use up or destroy natural resources •Able to last or continue for a long time
  • 3. Energy Efficiency Have skylights & right orientation in building Reduce Plug in Loads as they are controllable. Replace Boilers / Furnaces with new versions Have better ventilation / air conditioning
  • 4. Energy Efficiency Have skylights & right orientation in building Most How do you do that in an Existing Building? Reduce Plug in Loads as they are controllable. Solutions Are How easy is it to control the natural habits of your team members? Replace Boilers / Furnaces with new versions Incomplete Or What about the Loan you had taken to install the existing one? Have better ventilation / air conditioning Not Measureable Can your 12 year old calculate the savings involved?
  • 5. Introducing Solar Install Anywhere Limitless Potential Cap the Power Cost Measurable Impact Customize to Needs

  • 7. Provisions of the Companies Bill Relating to CSR Under the Section 135 of new Companies Act, 2013, passed by Parliament in August 2013, profitable companies must spend every year at least 2 per cent of their average net profit over the preceding three years on CSR works.
