Finally, a system cost breakdown shows that the Si-based solution is approximately 18% more than the SiC design. A 6.6 kW comparison also shows the superiority of the SiC design, with improvements across the board. These advantages add up to a net lifetime savings of ~$550 for the SiC system versus a Si design.
