The many faces of (photovoltaic) solar energy

Myth 1

Solar energy is only for niches


Fact is:

Solar energy has practically unlimited potential and is indispensable for a sustainable energy future

Myth 2

Solar energy is only sunbelt countries


Fact is:

Solar energy is very evenly distributed compared to all other renewables


Solar resource

solar irradiation in kWh/m2.day(source: ABB, 1998)


Myth 3

Solar energy will never become competitive


Fact is:

Solar energy is competitive with peak power today and will reach grid parity

in all of Europe within 10 years

Myth 4

Solar energy is a pain in the neck forurban planners and architects


Fact is:

Solar energy can give added value(s) to buildings and is on its way to become a

versatile building element

Myth 5

Solar energy is intermittent and unsuitable to build a reliable electricity supply


Fact is:

Solar energy in combination with other renewables, storage and a smart grid

can do the job

Myth 6

Solar energy is not sustainable


Fact is:

The system energy pay-back time in NL is only 3 years now and will be reduced to <1 yr, on a technical lifetime of 25~40 yrs

Solar energy is nice and may become important, but it’s better to wait a little


Facts are:

The heat is on now

We have no time to lose
