Potentially, yes. There’s usually a large initial cost when it comes to getting the technology installed in the first place. But there are long term savings to be had and making and utilising your own energy will reduce your carbon footprint considerably.
With PV panels, there’s also the potential to sell back excess energy you’ve made to the national grid via your regular energy supplier.
Alternatively, if you don’t fancy turning your house into a solar hot spot, then you can of course, buy renewable energy from your supplier.
