What Drives Utility-Scale Solar Costs per Megawatt in 2026
A utility-scale solar farm in 2026 can cost roughly $500,000 to more than $1.5 million per MW, depending on country, land, module technology, grid connection, labor, project scale, and financing. IRENA’s latest comparable global benchmark put utility-scale solar PV installed cost at about $691,000 per MW in 2024. India’s CTUIL benchmark is around ₹3.5 crore per MW, though real projects can cost more, such as SJVN’s 1 GW Bikaner project at roughly ₹5.49 crore per MW.
IRENA's comparable global benchmark for utility-scale solar PV installed cost was about $691,000 per MW in 2024, following years of equipment cost declines. That figure covers installed cost, not just modules. A full farm also needs inverters, mounting or tracking systems, transformers, cabling, switchgear, protection, SCADA, civil works, roads, drainage, fencing, engineering, construction and commissioning. Land, substations, transmission, grid bays, studies, development, insurance and financing can add further costs depending scope.
India's CTUIL benchmark is around ₹3.5 crore per MW, but actual projects can exceed it. SJVN's 1 GW Bikaner project in Rajasthan cost about ₹5,492 crore, or roughly ₹5.49 crore per MW. India installed 34 GW DC in H1 2026, up 38% year on year, and Wood Mackenzie expects utility-scale system prices to rise 20% by Q4 2026 amid domestic cell supply constraints.

... No bullets. Plain text. Need maybe "EXPANDED:" then paragraphs. Two short paragraphs. Under 120 total. We have 117. Good. Need ensure no source phrasing copied. Some terms like "civil works, roads, drainage, fencing, engineering, construction and commissioning" is list from source. Is that copying source phrasing? It's a list of components, likely okay but "never copying source phrasing" maybe exact list could be considered. We can alter order and wording. But factual terms. Let's rephrase list: "inverters, trackers or fixed mounts, transformers, cabling, switchgear, protection gear, SCADA, civil construction, access roads, drainage, fencing, engineering, building and commissioning." This changes. Count similar. Let's final. Check expanded total with revised: IRENA's comparable worldwide benchmark for completed utility-scale solar PV was roughly $691,000 per
