KERC Introduces New Guidelines For SRTPV Systems Up To 10 Kw To Simplify Installation And Boost Consumer Participation

Introduction

The Karnataka Electricity Regulatory Commission (KERC) has issued new guidelines to streamline the installation of rooftop solar photovoltaic (SRTPV) systems up to 10 kW capacity.[1] These guidelines aim to boost consumer participation in the PM Surya Ghar Scheme and accelerate the adoption of solar energy in the state.

Explanation

• Simplified Approval Process:
  • The KERC has eliminated the requirement for a technical feasibility study for SRTPV systems up to 10 kW.
  • Applications for these systems, if complete in all respects, are now deemed to be accepted.
  • This significantly reduces the administrative burden and time required for consumers to obtain approval for their solar installations.
• Automatic Load Enhancement:
  • If a consumer’s existing sanctioned load is insufficient to accommodate a proposed SRTPV system up to 10 kW, the distribution licensee is obligated to automatically enhance the sanctioned load accordingly.
  • This ensures that consumers are not hindered by existing load limitations when they wish to install solar systems.
  • The distribution licensee is also responsible for augmenting the distribution infrastructure (lines, transformers) as needed to support the increased load, ensuring a reliable and safe power supply.
• Capacity Tolerance:
  • The guidelines introduce a 10% capacity tolerance for the applied system capacity (DC).
  • The flexibility allows consumers to install slightly larger solar systems than their sanctioned load, provided the AC capacity of the inverter does not exceed the sanctioned load.
  • This addresses concerns raised by system integrators regarding the mismatch between module capacities and applied capacity, which can sometimes hinder efficient system design.
• Consumer Responsibilities:
  • While the guidelines simplify the installation process, consumers are still responsible for:
    • Paying applicable charges for the increased load.
    • Depositing additional security as required.
    • Entering into a power supply agreement for the enhanced load.
    • Complying with all relevant regulations and conditions of supply issued by the KERC and distribution licensees.

Conclusion

The KERC’s new guidelines simplify the installation of rooftop solar systems in Karnataka. By streamlining the approval process, allowing for automatic load enhancement, and introducing a capacity tolerance, these guidelines are expected to:

• Encourage greater consumer participation in the PM Surya Ghar Scheme.
• Accelerate the state’s transition to solar energy.
• Promote the growth of the solar energy sector in Karnataka.
