Solar Bankability – an O&M Perspective
Richard Jackson
An O&M Perspective
What is Bankability?
A term to describe the degree of financial risk?
Return On Investment
Why is it important to O & M Providers?
1. The site- project assessment
2. Design
3. Procurement
4. Installation –commissioning.
5. Maintenance- O & M

An O&M Perspective
Some important considerations
• Routine maintenance is important
• Planned maintenance does need to evolve and concentrate on predictive maintenance and have more interface with intelligent monitoring systems.
• Support from suppliers of key components
An O&M Perspective
Some important considerations
• Stocks of spares
• Analysis- review of reactive intervention
• Skillsets of workforce - needs to develop significantly across a range of technology's to be more inclusive and stand alone
• Boots on the ground is important- a balanced view

An O&M Perspective
Continuous Improvement
1. Feedback to design teams and manufactures
2. Analysis of how plants operate and change planned interventions.
Feedback to Designer/ EPC
Ensure proper communication &
feedbackbetween O&M andEPC, Supply Chain
for continuous improvement
An O&M Perspective
Continuous Improvement on the ground
O&M is becoming an important pillar
Maximize the ROI
Understand the real costs of Solar Asset Ownership
Ensuring that every kWh produced = optimized kWh
Mitigate the Operational Risk
Reduce the risks of equipment failure
Ensure data quality and analysis to support provision
of services to customers, utilities, grid
Enhance confidence on solar PV technology
Show to financing and political community the true potential of PV technology
in a reduced support scheme era
The O&M impact on the competetiveness of Solar PV as a serious and reliable energy generation resource is greater than ever
