SELF CONSUMPTION (SELCO)

  • About

    Apart from Net Metering, SELCO is another option for you to generate electricity from your own solar PV system and thus reduce your electricity bills. SELCO lets you consume all the electricity generated by your solar system, but no excess energy is allowed to flow into the utility network.


    The new revised SELCO Guideline (GP/ST/No.51/2024(Pin.2025) published on 23rd of March 2025 specified new criteria for SELCO application.
