2 System Solution for Industrial Diesel PV Hybrid Applications There are 6 key levers favoring PV-Diesel-Hybrid systems minimizing both, cost and risk 1. Reduction of variable costs Significant reduction of fuel consumption PV-Diesel-Hybrid system 2. Reduction of CO2 emissions Fullfilment of obligations and/or selling of certificates Enhanced business case / minimised cost 3. Scalability PV penetration rate can be scaled up continously. 4. Energy independence The solar ressource is always on site 5. Planning security Project is less dependent on fuel price volatility Enhanced supply security / minimised risk 6. Social aspects Project is „greener“ and more accepted by people Source: SMA analysis
