  1. Building solar assets to bridge the energy gap in India Industrial Rooftop Solar Projects • Key Considerations and Best Practices “Even if the solar industry were only to generate 40 percent of the world’s electricity with photovoltaic by 2040, that would mean installing more than 400 GW of solar capacity per year for the next 25 years.” Elon Musk

  2. What we do | We enable businesses transition to Solar Energy Advantage SunSure Utility Scale Plants 1 MW commissioned at Tohana 15 MW under execution at Davangere 4.5 MW as IPP at Davangere SP 1A* *Awarded Highest Performance and Financial Capability Rating by MNRE Open Access Ground Mounted 5.5 MW Captive Plant in Haryana Turnkey EPC Services Cutting Edge Technology Guaranteed Performance Our Customers Rooftop Solar Plants 7 MW commissioned & under O&M across 9 states5 MW under different stages of execution

  3. About SunSure | Bridging the energy gap in India Goal Accelerate India’s transition to a Renewable Energy driven nation Targeting 2 GW commissioned solar capacity by 2022 Business Large Scale and Distributed Solar Power Plants in emerging markets On/Off grid Solar Power Plants for Private and Public Institutions Operations & Maintenance of rooftop and ground mounted solar power plants Team Promoted and Managed by IIT / IIM Alumni and Industry Experts with rich multi-disciplinary experience Cumulative experience of 500 MW of EPC, O&M and Consulting projects for Solar plants

  5. Rooftop Solar | Key Commercial Considerations C O CAPEX Model RESCO Model • Up to 70% of Project Cost • 7 years of Tenure • 9.5% Rate of Yearly Interest Debt O&M • ~1% of Project Cost • Escalating @5% • PVsyst estimates • Panel Degradation • Grid Rate Escalation PPA Tenure Tariff Design Energy • Escalating Tariff • Fixed Tariff • Grid Tied Escalation • 10 – 25 Years Tenure options • Tariff offer more attractive for longer tenure PPA BuybackPricing • Define lock-in period • In-built buyback option for each PPA year Incentives Equity • Interest Lost • Payback Period • Net Metering • Accltd. Depreciation

  6. Rooftop Solar | Achieving Commercial confidence Case Studies • Create customer generation case studies • Include actual electrical cost savings data • Back-up low generation with correct reasons – educate on PR% Referenceability • Encourage interested industrial associates to visit existing installations • Facilitate stakeholder meetings with decision makers as well as maintenance personnel Sound Financial Modeling • Ensure that your financial modeling includes all expenses and benefits • Customer tax and debt structuring is crucial to modeling CAPEX investment returns • Net Metering and Grid availability is crucial to make OPEX plant successful

  7. Rooftop Solar | Achieving Operational Confidence Synchronization with DGs • In most parts of India, ~20% of industrial energy requirement is met with DGs • Solar inverters provide control feature through SCADA • The D-Panel SLD must be studied to create an effective control algorithm Plant Performance • Real Time Monitoring of the system (Remote) - String Level • Daily / Weekly reporting of plant generation shared with key stakeholders • Automated SMS/e-mail alarms set for key plant issues • Warranties: 25 Year performance warranties on Modules, 5 years on inverters • Preventive Maintenance schedules must be created – quarterly inspections and testing • Data management of testing, warranties and corrective maintenance at plants Maintenance of Equipment Project Management • Rooftop solar must not be an intrusive experience for industries • Expectation setting and transparency in project management process • Proper documentation and training to be imparted for working around system

  8. Sunsure Practices | Client Case Study Sharing actual case studies with interested parties builds confidence – like the 27% savings for one of our clients in Haryana Data from actual electricity bills

  9. Sunsure Practices | DG Synchronization Sunsure synchronized a 600 kWp Rooftop Solar Plant to 4 diesel generators of capacities 250 kWp to 1250 kWp Irradiation DG Power Solar Power

  10. Sunsure Practices | Weekly Reporting All key stakeholders receive Weekly / Daily Reports, Alarms and notifications on plant equipment maintenance activity Weekly Reporting Mail Daily e-mail Alert SMS

  11. Sunsure Practices | Data Driven Preventive Maintenance Comparison of power generation over a typical day Of All our portfolio plant equipments are continuously compared to each-other to in order to ensure consistency in asset performance 6 AM to 10 AM: Similar Power distributions for both plants Peak Time: ENCR Plant shows “twin-peak” distribution. This implies unstable generation at peak power outputs. Results in “derating” of inverter.

  12. Sunsure Practices | Project Management Each project is managed using cloud-based PM platform – the team is always connected and the client always aware!
