Provided you have the roof space for both solar power and solar hot water panels, yes – absolutely! These systems do, after all, fuel your home in different ways, with solar thermal panels heating your water and solar PV panels providing you with clean power (which you can sell back to the grid via the SEG when you have excess) and light.
If roof space is an issue but garden space isn’t, you might consider ground-mounted solar PV panels to complement your rooftop-based thermal ones. Mounted on either a traditional racking system or a raised pole structure, these solar panels are built to optimise their exposure to the sun, making them even more energy-efficient than roof-mounted panels.
