Chi phí năng lượng mặt trời tăng 18% nhưng vẫn rẻ

Chi phí điện năng mặt trời quy mô lớn tăng 18% lên 40‑98 USD/MWh nhờ chi phí vốn, lãi suất, thuế và áp lực chuỗi cung ứng. Dù tăng, năng lượng mặt trời vẫn giữ vị trí nguồn điện rẻ nhất cho các dự án mới trên thế giới.

Tăng chi phí do các yếu tố kinh tế

Giá vốn thiết bị tăng do thuế nhập khẩu và các khoản phí trên tấm pin, pin lưu trữ và inverter, đặc biệt là hàng hoá từ châu Á. Lãi suất vay tăng làm chi phí tài chính dự án cao hơn. Ngoài ra, chi phí vận chuyển và gián đoạn chuỗi cung ứng cũng đẩy giá lên.

Chi phí vốn và lãi suất

Vốn đầu tư ban đầu tăng 10‑15%, lãi suất vay trung bình tăng 2‑3 điểm phần trăm, làm tăng chi phí mức độ năng lượng (LCOE) đáng kể.

Vẫn là nguồn điện rẻ nhất

Khi tính cả chi phí phụ trợ để ổn định lưới, năng lượng mặt trời vẫn có LCOE thấp hơn than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than than
