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
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.
With solar balconies, no such consent is required unless the facade is listed as of historic interest or there is a specific prohibition from the residents’ association or the local authority. Furthermore, as long as the installation does not exceed 800 watts it doesn’t require certification, which can cost from €100 to €400, depending on the area.
As with all solar power systems, balcony power only works in daylight and a battery storage system can add at least €1,000 to the installation cost.
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.
I’m in that in-between use where it’s a tool van. So I have acreage for solar on the roof and 1200W. I negotiated a remarkably reasonable rate with myself for the install.

Really great day. When you can screw yourself.
