Insolare Energy Unlisted Shares: A Solar Sector Investment Guide

The Indian government's initiatives in renewable energy have made solar EPC companies some of the most talked about companies in the unlisted stocks market. One of the companies in discussion is Insolare Energy Limited. The following is an analysis of what the company is all about, how its unlisted stock market looks like, and some considerations when investing in the company.

Who Is Insolare Energy?

Started in the year 2009 and located in Ahmedabad, the company named Insolare Energy is an EPC company that provides services related to solar power projects such as rooftop, ground-mounted, floating solar, and solar parks to C&I clients. In addition, the company has also been exploring in energy storage and green hydrogen.

Its EPC model is asset-light; it does not own and operate power plants but instead earns income from designing and executing power plant projects for its clients. This implies that the financial performance of the business is determined largely by the size of its order book and its speed and efficiency in execution. It has a presence in 19+ states and has installed over 500 MWp capacity, including an increasing O&M portfolio.

Key difference: Insolare Energy (which is not publicly held, ISIN INE0TSJ01021) and Insolation Energy Limited (listed, BSE/NSE symbol: INA) are distinct entities. It’s very confusing to distinguish between the two due to the similarity in their name.

What the Unlisted-Share Data Shows

Numbers from unlisted share websites (they change often and differ by source, hence are only estimates and not precise figures):

• Suggested share price: approximately ₹165 per share as of early September 2026, between 52-weeks high/low of approximately ₹165 – ₹205
  
• Face value: ₹2 per share
  
• Income statement turnover: approximately ₹434 crore in FY25
  
• Return on equity: approximately 11.21%
  
• Common minimum number of lots: approximately 1,000 shares
  

However, here is a warning about these figures: aggregators for unlisted shares use prices from the brokers' desks or OTC deals instead of using the order book of the exchange, and therefore, figures such as market capitalization to revenue ratios might not match between the various platforms. It is always advisable to confirm current figures through a broker.​

How Buying Unlisted Shares Actually Works

Unlisted stocks cannot be purchased from a conventional demat or trading app since these stocks aren’t listed. This is the common procedure on most apps:

• Confirm a trade at the agreed trading price with the broker or platform
  
• Make KYC submission of PAN card, CMR, and cancelled cheque
  
• Fund transfer through NEFT/RTGS/IMPS – cash is not accepted
  
• The shares are credited to your demat account, generally within 24 hours of completion of fund transfer
  
• The process for selling stocks works vice versa with the broker or platform as the opposite party

Lock-in periods are important. Several platforms highlight the fact that in case of an initial public offering by Insolare Energy, stock purchased prior to the IPO would be under a lock-in period of six months following the date of listing.

Why the Solar EPC Sector Is Attracting Interest

​The following factors make some sense of the investor interest in unlisted solar EPC companies:

• Policy push: India’s renewable energy capacity goals, the PM Surya Ghar program, C&I open-access policy and states’ own solar policies continue to create a larger addressable market for the EPCs.
  
• Corporate decarbonization: The growing demand by manufacturing and corporate customers on sustainability fronts creates orders for rooftop and utility-scale solar.
  
• Moving to storage & hydrogen: Companies diversifying themselves into energy storage solutions and green hydrogen are positioning for the next stage of the energy transition, although it is still an unproven revenue stream.
• Pre-IPO investment: Investors at times look into rapidly growing relevant sectors’ unlisted companies to invest in and gain value before their likely IPO, although there is no assurance that Insolare Energy might go public.

Key Risks to Understand Before Investing

​Unlisted shares are structurally distinct from listed stocks, and the dangers are very real:

• Illiquidity: There are no order books for trading. Sale happens through finding a counterparty (usually the same broker that sold you those shares) and negotiating the price.
• Valuation opacity: Due to lack of disclosure requirements by exchanges, there is heavy reliance on broker's estimates as well as self-disclosures of the companies concerned.
• Listing risk: Investment in pre-IPO shares involves taking a view that listing will actually happen and will be done in a manner and at a valuation that is assumed by today's valuation of such stocks.
• EPC business-model risk: The asset-light EPC revenue is lumpy in nature and depends on winning orders, executing them and recovering cash flow - working capital risk is inherent in this model.
• Documentation & regulatory risk: SEBI KYC requirements apply but the unlisted segment is much less regulated compared to listed one - take care while verifying credentials of your broker and genuineness of share transfers.
• Concentration Risk: Unlisted investments in solar EPC carries more concentrated policy and commodities risk (module pricing, import duties, etc.) compared to diverse portfolio.

Bottom Line

Insolare Energy is a company that finds itself in the crossroads of two highly popular investment stories in recent times – solar growth in India and the buying of stocks of companies ahead of their initial public offerings. This may be true, but the important factors that matter to an EPC company like the order book, the execution capabilities, profit margins, and working capital must not be ignored.
