      >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

      For this to work, you also need to install a grid-tie inverter. So, yeah, there’s some installation cost there. This would be a bureaucratic nightmare trying to get past a condo association in the US.

      400w panels are currently about 70 euros a piece and a dual input inverter costs about 130. You can install a system like this for less than 400 total, just dont use the flexible junk as shown in the photo. They will likely fall to bits after a couple of years.
