Solar panels for apartments and communities in Spain
Apartment solar is possible, but roof rights and the chosen self-consumption arrangement need resolving before equipment is designed.

QUICK ANSWER
Can an apartment community install solar panels in Spain?
Yes. A community can install solar for communal demand or establish collective self-consumption for participating supplies. The decision process, roof rights, technical design, allocation agreement and registration must match the arrangement.
Decide what the solar will serve
One option offsets communal electricity such as lifts, lighting, pumps and shared cooling. Another allocates collective generation among participating homes or premises.
Obtain data for the relevant supply points before deciding how much roof capacity is useful.
Map ownership and approval first
The community administrator and governing documents can help identify roof rights, common elements and the correct decision route.
Protected buildings, visible structures and municipal requirements may add constraints. Check these before deposits are paid.
Allocation needs documentation
Collective self-consumption assigns generation among participating supplies through agreed coefficients and the applicable administrative process.
The agreement should cover participation, allocation and future changes. IDAE publishes specific guidance.
Treat roof space as a limited asset
Water tanks, plant, access routes, shade and safety clearances reduce usable space. Show the layout and expected production rather than dividing roof area by apartment count.
Maintenance access and responsibility also need recording.
