Something that might help with apartment and city micro-grid solar is panels that are transparent in visible light while converting the energy of UV and infrared - they're still under 10% efficient in the best case I could find quickly vs. about 15% for conventional photovoltaics, but your typical high rise has a lot of glass frontage, even if other buildings may cause significant shadows in crowded city centres so not every installation would see optimum results.
