Solid Solar commissions 20 MW plant in Uttarakhand
Solid Solar has commissioned a 20 MW hilly-terrain photovoltaic plant in Uttarakhand, with Gautam Solar supplying TOPCon bifacial modules for the installation. The commissioning was reported by Odisha Diary on 29 October 2026 and by pv magazine India on 30 October 2026. No project value was disclosed in either report.
The plant represents a technically distinct category of solar deployment: hilly or mountainous terrain requires adapted mounting systems, logistics planning and civil engineering approaches that differ significantly from flat-land utility-scale projects. TOPCon bifacial module technology is suited to such environments, where rear-side albedo from rocky or snow-covered ground can contribute additional energy yield.

Technology context: TOPCon bifacial in challenging terrain
TOPCon (Tunnel Oxide Passivated Contact) bifacial modules offer higher efficiency and dual-sided energy generation compared with standard monofacial PERC panels. Their deployment in Uttarakhand's hilly terrain underlines a broader industry move toward higher-efficiency technologies in locations where land availability is constrained and installation costs per MW are elevated. Both reporting outlets specifically identified the module technology as central to the project's design.
Solar pipeline across India: where activity is concentrated
Projects India tracks 1,315 solar-based power projects across the country, with 24 added to the database in the last 90 days. The pipeline is geographically concentrated in Maharashtra (189 projects), Karnataka (188), Telangana (139), Andhra Pradesh (93), Gujarat (86) and Rajasthan (84). Uttarakhand, while not among the top six states by volume of tracked projects, is emerging as a location for technically demanding solar installations where terrain constraints are manageable with the right technology and developer expertise.
By stage, the pipeline skews heavily toward early-phase activity: 643 tracked projects are under approvals, 194 are in planning and 25 are at the early or announced stage. Only 221 have reached construction and 129 are completed. This distribution signals a large forward pipeline of procurement opportunities across civil, electrical, module supply and balance-of-system scopes, even as commissioning events such as this Uttarakhand plant mark the conversion of earlier-stage work into operational capacity. A full list of tracked projects is available on the platform.
Recent solar projects entering the tracked pipeline
Among projects recently added to the Projects India database, several illustrate the breadth of solar activity under way nationally. NTPC Renewable Energy Limited has projects at Dhule in Maharashtra and Sitapur in Uttar Pradesh (the latter valued at Rs 1,338 crore) both at the construction-started stage. Adani Green Energy Limited is constructing a plant at Khavda, Kutch in Gujarat at Rs 469 crore. KPI Green Energy Limited's floating solar project at Kadana Dam in Gujarat (Rs 489 crore) is also under construction. At the approvals stage, Nacof Oorja Private Limited is pursuing a Rs 2,025 crore plant at Bikaner, Rajasthan. These projects reflect activity across flat-land, floating and hybrid solar formats, complementing the hilly-terrain segment represented by the Uttarakhand commissioning.
For context on other recent project completions in mountain and challenging-terrain environments, see the 2 MW solar-plus-storage project inaugurated in Spiti, Himachal Pradesh, which similarly required specialist installation approaches.
What this means for suppliers and contractors
The commissioning of a 20 MW hilly-terrain plant in Uttarakhand by Solid Solar using Gautam Solar TOPCon bifacial modules is a reference data point for several categories of supplier. Module manufacturers and distributors with TOPCon bifacial product lines can point to a commissioned project of this scale and terrain type when approaching developers active in hill states. Civil and structural contractors with experience in mountainous site preparation, access road construction and adapted mounting systems have a relevant local case study.
More broadly, with 643 solar projects in the approvals stage nationally, the pipeline of near-term procurement decisions is substantial. Suppliers that position early — particularly in states with high project concentrations such as Maharashtra, Karnataka and Telangana — are best placed to capture engineering, procurement and construction opportunities as projects move from approvals into construction. The 24 projects added to the solar tracked database in the past 90 days indicate a continued flow of new opportunities entering the intelligence pipeline.
Frequently asked questions
Who commissioned the 20 MW hilly-terrain solar plant in Uttarakhand?
Solid Solar commissioned the 20 MW hilly-terrain photovoltaic plant in Uttarakhand. The plant uses TOPCon bifacial modules supplied by Gautam Solar. The commissioning was reported by two outlets in late October 2026. No project value was disclosed in either report.
What modules were used in the Solid Solar Uttarakhand solar project?
Gautam Solar supplied TOPCon bifacial modules for the 20 MW hilly-terrain solar plant commissioned by Solid Solar in Uttarakhand. Both outlets that reported the commissioning specifically identified the TOPCon bifacial technology as central to the project.
How many solar projects are tracked in India?
Projects India tracks 1,315 solar-based power projects across India, with 24 added in the last 90 days. Maharashtra leads with 189 tracked projects, followed by Karnataka with 188 and Telangana with 139. The majority of projects, 643, are currently under approvals.
