Industry average 300w panel (17% efficient) is about 1.6m² and comes in at about $0.40/W wholesale. At scale you can go cheaper. Manufacturing cost is likely lower. Shipping costs can be 15-20% on top of that. ~$120/m². What would be helpful to know: How much of every material is required/m²? How much does 1m² weigh? What is the 75% output lifetime? Efficiency graph at varying solar iridescence? Manufacturing yield rates?
