'If 1.5m Germans have them there must be something in it': how balcony
solar is taking off
Balcony solar panels can save 30% on a typical household's electricity
bill and, with vertical surface area in cities larger than roof space,
the appeal is clear
...
...
Panels have already been installed on about 1.5m German balconies,
where they are so popular the term Balkonkraftwerk (balcony power
plant) has been coined.
Manufacturers say that installing a couple of 300-watt panels will
give a saving of up to 30% on a typical household's electricity bill.
With an outlay of [Euro] 400-800 and with no installation cost, the
panels could pay for themselves within six years.
In Spain, where two thirds of the population live in apartments and
installing panels on the roof requires the consent of a majority of
the building's residents, this DIY technology has obvious advantages.
