Even in a narrow and long corridor it is possible to install a domestic photovoltaic system on a flat roof.
And even the presence of very high parapets that can create shading on the photovoltaic panels are not a problem if you choose Sun Ballast as support.
For this reason, our customer Alba Renova S.L chose the raised single row 5 ° ballasts, placing the solar panels vertically to create a 9 kWp flat roof system in Zaragoza, Spain.
