For scenario 3, the large increase in the tourism sector meant that electrical demand during the summer months was much higher than scenarios 1 and 2, or the current system on the island. It was thus beneficial to keep the PV installation of scenarios 1 and 2, but with the installed capacity increased to 750kW in order to allow more of the summer demand to be met by renewables. In order to keep exports within the limit, the installed capacity of lithium-ion batteries also had to be increased, up to 1.68MW. The full schematic of the scenario 3 energy system is shown across.

Despite the increase capacity of PV panels, grid imports are still more prominent in summer than in winter, with total generation from renewables being higher in winter and lower in summer. This is evident in the monthly average electric production graph, where the contribution from the grid is noticeably larger in summer months than winter, despire the increased PV output in summer. The increased installed renewable system capacity gives reduced grid purchases compared to scenario 2, however they are still significantly higher than scenario 1.
