Types of Challenges
Development• Permissions• Avenues for
Revenue• Grid related• Financing• Identification of
Partners
Management• Ownership• Access for O&M• Regular
payment recovery
• Replacement costs
• Distributed installations

Development challenges
Awareness of all stakeholders Utility worry about losing well-paying
customers Uncertain policies and changing scenario Process and documentation for project
development in various models Financial closure – project financing Identification of roof owners Identification of suppliers, EPC, O&M
5
Management challenges – 25 years??
Grid availability and quality – LV level Financial strength of utilities or private
clients Payment security mechanism Changes to roofs, locations – own and
neighbors Service manpower and spares Re-validation of different agreements Changes in consumer loads in net
metering Emergency backup supply for buildings
6
Technology challenges
Grid tied inverters – certifications and standards
Roof fixing techniques and availability Protection features Regular calibration of various equipment Timely replacement of components Recycling methods and setups for
material
7
Few Specifics – Net Metering Regulations are yet in draft stage Each SERC has to have own regulation for
the state – requires time Currently net metering attractive only for
high tariff consumers – needs additional incentives
State-wise different connectivity specifications
Low voltage grid strengthening necessary at many places
8
Few Specifics – Gross metering Utilities unwilling / unable to provide FIT
due to possibility of further reducing costs of solar energy
Private customers (for third party sale) unwilling to have long term PPA
Charges of transmission, wheeling, distribution and CSS are high, making solar energy more expensive
