Savings come from two sources: self-consumption (reduced grid purchases) and feed-in export (selling excess to the grid). With a 25-year system life (0.5% annual degradation), the long-term returns are substantial.
Solar irradiation in your region, system size, self-consumption ratio, and local electricity rates all impact your final returns. Generally, the higher your self-consumption ratio, the better your overall ROI — since retail electricity rates far exceed feed-in tariffs.
From project assessment, system design, and equipment procurement to installation, grid connection, and O&M — we provide full-chain service. 500+ commercial projects completed, 100MW+ distributed solar deployed. Book a free site survey for a customized solar proposal.
