Balkon-Solarmodule können 30 % der Stromrechnung eines typischen Haushalts einsparen, und da die vertikale Fläche in Städten größer ist als die Dachfläche, liegt die Attraktivität auf der Hand. 300-Watt-Panels kosten 400–800 €, ohne Installationskosten. Sie amortisieren sich in 6 Jahren

>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 €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.
>“Balcony power is another piece in the puzzle,” she says. “They are another step towards using the built environment to generate electricity.”
>Vernetta says the vertical surface area of cities is far greater than that of the roofs and that, in Spain, balcony panels benefit more than roof panels from the low winter sun.
>Cities such as Helsinki are already experimenting with buildings with solar panel cladding.
Laughs in body corporate rules 😂, if only it was as simple as buying and installing it
