below 50% of the available rooftop
areas (Fig. 5).

How can we realise this great potential
and help ourselves deliver on the Paris
agreement?

Hardware costs should no longer be
a barrier. Already in 2017 the costs
of direct current (DC) electricity in
central Europe at the PV module level
have dropped to less than 0.02 EUR/
kWh. In efficient markets the costs
of systems is around €1300/kW, with
potential to close the gap further on
large-scale ground mounted systems,
but economies of scale put limits on
this ultimately. A lot however needs
to be done to bring prices in all EU
regions to the benchmark levels in
major markets. Soft costs are another
area where huge improvement can
be made. Community initiatives and
de-risking instruments can also play a
key role.

Last but not least, the Energy

Performance Building Directive and
