SERIS is a research institute at the National University of Singapore (NUS). SERIS is sponsored by the National University of Singapore (NUS) and Singapore’s National Research Foundation (NRF) through the Singapore Economic Development Board (EDB).
THE “PV SYSTEM DOCTOR”
A smart and innovative O&M service that provides a comprehensive health check for photovoltaic (PV) systems. It consists of three “health choices” which can be booked individually or as a package:
• Real-timemonitoringofPVsystems• Advancedon-sitediagnostics• Independentfinancialassessment
REAL-TIME MONITORING OF PV SYSTEMS
Usingourstate-of-the-artproprietarymonitoringsystem,which includessmartsensorsand big data analytics coupled with an intuitive graphic user interface (GUI) enables continuous measurement of actual PV system parameters down to the individual string level.
We provide: • Independentpoweroutputmeasurements(beyondinverterreadings)• Actualirradiancemeasurements• Ambientandmoduletemperaturemeasurements• Performanceratio(PR)calculations• Earlyfaultdetectionbycontinuousbenchmarkingof: - Stringperformanceagainsteachother - Systemperformanceagainstsimulatedbehaviourunderoptimalconditions - Plantperformanceagainstpeerinstallations

INDEPENDENT FINANCIALAESSESSMENT
Anunder-performingPVsystemresults inrevenue losses and reduction of expected returns. Even small deviations from the optimal performance ratio can negatively impact a project’s financial return andcashflow.Ourfinancialserviceteamoffers:
• Financialimpactanalysisofthe under-performance• Life-cyclecost/benefitanalysisof requiredrectificationworksneededto bring the system back to its optimum performance

SERIS can assist project owners and developers in the design of their PV systems for performance optimisation and to meet the highest quality standards, inparticular for installations in the tropics. SERIS’ project services start from initial yield estimations until the systems are fully operational and perform as originally planned.
SERIS also works with lenders on thetechnicalandfinancialevaluationof a proposed solar project. TypicalPVsystemservicesofferedby SERIS are illustrated by the image on the right.
FLOATING SOLAR
SERIS has special expertise in the area of “Floating Solar” where it operates the World’s largest testbed of Floating PV installations and carries out technical and financialassessments around it.

TECHNICAL & FINANCIAL FEASIBILITY STUDIES
We offer a wide range of feasibility studies, from specific technical questions tocomprehensivestudiesincludingcommercialandregulatoryaspects,forexample:
• Technicalandeconomicfeasibilityofsolarprojectsofanysizeandanydeployment option,e.g.ground-mounted,floatingPV,orroof-top.• Commercialandregulatoryfeasibilityoflarge-scalePVprojectsinAsia• Analysis of solar PV potential for cities and regions • Solar PV roadmaps

VERIFICATION OF RENEWABLE ENERGY CERTIFICATES FOR SUSTAINABLE REPORTING
As multi-national companies move towards sustainable goals and climate-friendlypolicies,theneedforaplatformtotransactrenewableenergycertificates(RECs)becomesmore evident. SERIS was instrumental for the launch of the Tradable Instrumentsfor Global Renewables (TIGRs) platform in 2016, supporting Singapore’s move tobecome the regional hub for renewable energy.

NATIONAL SOLAR REPOSITORY (NSR) OF SINGAPORE
One of SERIS’ key goals is to “solarise” Singapore and help to disseminate solar information tothepublic.TheNSRwebsite (www.solar-repository.sg)containsmanyfeatures,suchasadynamicSolarEconomicHandbookwhichisregularlyupdated,aLCOEcalculator,PVsystemdatabase,real-lifeirradiancemap,andmore.
ENVIRONMENTAL ATTRIBUTES ASSESSMENT FOR RENEWABLE ENERGY PROJECTS
SERIS has developed an Environmental Attributes Calculator (EAC) available underwww.eac.seris.sg where clients can download Environmental Attributes Assessment reports for renewable energy projects with country- or region-specific features.The tool enables clients to visualise equivalencies of the amount of green electricitygenerated and avoided carbon emissions throughout the economic life span of a project.
