10 x 425W JinkoSolar panels installed on our Cardiff south-facing slate roof. Paired with a 7kWh GivEnergy battery. System size 39kWp. Total £8640 fitted. MCS-certified installer, RECC consumer-code member.
Three MCS-certified solar firms quoted via BestBuilders for our Cardiff bungalow. Picked the mid-priced quote at £8000 - 12 panels and a 5kWh battery. Scaffold up Monday, panels installed Tuesday-Wednesday, commissioned Thursday. Generation already paying for itself - bill down 70%.
Two summers later and the battery has paid back about 35% of itself already. Installer near Cardiff recommended panel optimisers because of the gable shading - good call. Best decision we have made on this house.
