History of TÜV Rheinlands Business Field Solar Energy

7/7/2015 Introduction TÜV Rheinland and PV Services 4

PV Services, Introduction

More than 30 years experience in the

field of solar energy

Global network of more than 200 solar

experts

More than 12 GW inspected PV plants

world Wide (Europe, North America,

South America, Central America, Asia

and Africa)

Research and development in the

area of power plant optimization and

module qualification (characterization

and life time assessment)

Active participation in the important

standardization committees

7/7/2015 Introduction TÜV Rheinland and PV Services 5

TÜV Rheinland operates 7 accredited

solar laboratories (Cologne/Germany,

Bangalore/ India, Daya/Taiwan,

Yokohama/Japan, Shanghai/P.R./China,

Gyeongsan/South Korea and

Tempe Arizona/ USA)

energy yield prediction too optimistic,

cleaning concept missing or insufficient,

lack of fixed contract requirements, lack

of experience

Project assumptions

and feasibility are

imprecise

How to solve

these problems?

Quality: Market Situation

Solar Energy UK 2015 6 14.10.2015

Product quality is often insufficient

due to the market situation (high

competition, low financial recourses,

personnel fluctuation, supplier change,

lack of quality assurance

knowledge)

Low quality of planning and installation

use of sub- and sub-subcontractors, high

competition, lack of knowledge and

experience, tight commissioning

deadlines, weak quality

assurance during

construction

unstable market situation, choose

of Tier-1 manufacturers is not only a

criteria for bankability,

warranties are often not reliable

Bankability of involved

parties often not given

Why Modelling and Monitoring?

Challenges and Needs

Yield predictions are critical: Determination of risks, finance and value

Decision makers for or against a project rely on precise yield predictions and

according performance of a PV plant

The challenge includes the following issues:

Data: availability and quality (matching of yield estimation and monitored

real life data)

Tracking: Accuracies and continuous quality control of measurement

system

Special Impacts: weather impacts (e.g. soiling, snow etc.), spectrum,

paired with temperature and humidity conditions

Module and system technologies: bifacial, PERC, thin-film (meta-

stabilization processes)

Module data for Yield assessment third party requisite?

Degradation factors (browning, snail trails, micro cracks, hot-spots,

polymeric cracking) Are we aware everything?

7/7/2015 Introduction TÜV Rheinland and PV Services 8

Why Modelling and Monitoring?

Challenges and Needs

We need:

Precise, reliable and high-quality data inputs on every level ranging from

weather to BoS data

Intensified standardization on methods for implementing loss factors

AND: investors, lenders, operators and EPCs asking (!) for such quality

modelling and monitoring

The decision for the realization, financing and operation of current and

future plants is at risk,

if the yield estimate and plant observation is a laissez-faire policy.
