The Cost of Solar Power Solar Panels - Green Power
如果成本可以break down下來, 每個環節中自己的value是甚麼, 憑甚麼讓人願意找你?
60% for the solar panels themselves – based on photovoltaic panels (silicon is expensive)
10% for the solar inverter (it takes direct current from sunlight and converts it into alternating current for us to plug int0)
15% for parts necessary for installation (wires and racks, etc.)
15% for labor
