Installing solar panels on flats have the potential to save you around 50% on your electricity bills, and 70% if you utilise the Smart Export Guarantee (SEG), but more on that below. If multiple flats share a solar panel system, it's likely that more of the electricity produced by the panels will get used, instead of being sent back to the grid.
The 2023/24 consultation on the detailed specification for the FHS sought views on whether to require solar photovoltaic (PV) panels for new homes. Solar PV generation turns the sun's energy into electricity. Option 1 would have required solar PV panels covering the equivalent of 40% of a new home's ground floor area.
The rooftop installation of photovoltaic panels can be accomplished using three mounting methods: independent support, enclosed attachment, and forced cooling. However, the enclosed attachment method may lead to temperature concentration and reduced photovoltaic performance.
If your flat is in a conservation area, you need to contact your local council. When implementing a shared solar panels system on your block of flats, you need to check if your neighbours own part of the roof. If they don't and you've obtained all the relevant permissions, you don't need their permission to install solar panels.
However, we usually recommend placing your solar panels on a south-facing roof, at an angle of between 20 and 50 degrees. Your panels will then be exposed to more sunlight, which will generate more electricity for you. There isn't an issue if your roof is flat or steeper than 50 degrees, however.
