There may be other electricity usage, for example, for lifts or gates, but again usage tends to be low so payback time for PV panels is quite long.įor one apartment, like your own, the economics will depend on the pattern of electricity usage.
Normally, there is no heating and the lights would be low-energy LEDs, perhaps supplemented by motion sensors. However, for common areas, electricity usage tends to be low. I would note at the outset that while managing agents have a perspective on these issues, we are not specialists on the technology involved so you may need separate advice on that. You raise a number of interlinked issues. I note that the Green Party is keen to increase the installation of solar panels, which may mean that grants might be available in the future. Have come across this issue before and, if so, what might be the pros/cons? Perhaps the management company should also consider PV panels for the common-area electricity?
I understand that the roof is a common area and I will have to engage with the owners’ management company to try and develop this idea. So, in theory each apartment could have access to 15sq m (161sq ft) or so of roof, given that there are 10 apartments in the block. I estimate that the usable space for solar panels on the south-facing side of the roof is around 168sq m (1,808sq ft). I am about to start a renovation project and wondered about approaching the owners’ management company at our agm to seek permission to install a PV solar panel on the roof. I own an apartment on the second floor of a two-storey block.
