Costly mistake - I wouldn't touch it with a bargepole! Project Solar UK installed in June 2019, this is the third time we are having to call them out due to issues with the installation. To date, we can't even tell if we have made a penny of saving as their call out charges of a hefty £325 defeats the purpose of us even having solar panels. They make you sign small print which apparently allows them to continue to rip vulnerable customers off. It's been a costly mistake! Do not go anywhere near this company if you need solar panels installed - AVOID AT ALL COSTS!!
