European Research Issues


Background l.jpg
Background

  • EU RTD projects

  • EU demonstration projects

  • IEA PVPS Task 7


Market description l.jpg
Market description

  • 3 main players: US, EU (Germany), Japan

  • 4 - 5 main market segments

  • 4 types of customers

  • 3 marketing concepts


Market segments l.jpg
Market segments

Housing

new / existing

houses / apartment blocks

PV building surfaces / PV kits

Power stations

ground based / rooftop systems / sound barriers

Commercial buildings

public buildings / office buildings

large roofs / facades


Main customers l.jpg
Main customers

Private building owners

Housing associations

Commercial building owners

Public adminstration

Utilities


Financial concepts l.jpg
Financial concepts

Buying a subsidized PV system (-> buying a green

or low / zero-energy house)

Investing in a PV system (-> based on rate based

incentives)

(-> towards a contracting mix)

Buying green energy (-> the utility invests)




Trends world wide l.jpg
Trends world-wide

Japan

  • current world market leader (57 000 houses, 210 MWp installed PV capacity)

  • successful matching of PV and building industry (-> functional systems)

  • shift expected from internal to external market

  • limited attention for architectural BIPV


Trends world wide 2 l.jpg
Trends world-wide (2)

US

  • "catching up"

  • 1 000 000 Solar Roofs programme

  • National Energy Plan

  • added value of building integration and architecture less perceived (-> functional systems)


Trends world wide 3 l.jpg
Trends world-wide (3)

Europe

  • market segments vary from country to c.

  • historically: focus on BIPV

  • market leader in high-end BI PV modules

  • strong in BIPV systems development (AC modules, string inverters, connectors, rooftiles, ...)

  • moving from architectural to functional integration


Observations in eu countries l.jpg
Observations in EU countries

  • Germany

    42 MWp installed in 2000, 20% large systems

    financing through rate based incentives

  • Switzerland

    1996 - 2000: 4 MWp installed in solar stock exchanges

  • Netherlands

    2000: 2 MWp installed

    30 - 50% through green electricity

    40% small plug and play systems (PV kits)


General observations l.jpg
General observations

1) continuous market increase

2) shift from innovators to early adopters

3) shift from architecturally integrated to functional system

4) limited attention for optimized integration into the building energy system(building envelope, building energy system, building economics)


Outlook l.jpg
Outlook

Assisted market expansion and transition is required

Two main market directions perceived:

1) PV as part of a (green) energy portfolio

2) PV as part of a (green / low energy) building concept


Required rtd and market developments 1 l.jpg
Required RTD and market developments (1)

For the green energy portfolio

  • Low cost PV systems

  • Understanding of grid-interaction of large systems

  • Installation and maintenance concepts and companies

  • Standards and quality schemes

  • Green energy labels


Required rtd and market developments 2 l.jpg
Required RTD and market developments (2)

For the green / low-energy building concept

  • PV optimized for building integration and for the building energy system

  • Energy in Buildings’ directives suitable for PV

  • Clear grid interconnection & PV systems guidelines

  • Integration into the building industries' traditions and modus operandi

  • Reduced gaps between component industry and the market (reducing transaction costs)


Summary l.jpg
Summary

PV technology is available and accepted by

the innovators

Markets now need to transform to be able to reach new customers with reliable, well-perceived and affordable systems and concepts
