Solar sector PE near 48.6-58.0. Waaree Energies trades at 18.9x. Websol Energy Systems at 10.9x. Premier Energies at 27.1x.
Quick Answer
Three solar stocks, Waaree Energies, Websol Energy Systems and Premier Energies, are trading well below their respective sector average price to earnings ratios while all three post strong double digit return on equity. Websol Energy Systems posts the highest return on equity of the group, while Waaree Energies is the largest of the three by market capitalisation. This gap between valuation and profitability is why these solar stocks stand out on a simple sector screen, though a formal buy rating needs deeper company specific research.
India’s solar manufacturing industry produces photovoltaic cells and modules, benefiting from government incentives and rising domestic renewable energy capacity addition targets, which have pushed valuations across the space to rich levels. Not every stock in the space trades at the same multiple. A screen of listed solar stocks against their sector average price to earnings ratios surfaces three names still priced well below that benchmark.
Waaree Energies, Websol Energy Systems and Premier Energies all currently trade well below their respective industry PE benchmarks, while all three post strong return on equity. This piece breaks down why each stock screens as undervalued, what the underlying financials show, and the risks that come with owning solar cell and module manufacturers.

Why These Solar Stocks Screen as Undervalued
The solar manufacturing industry currently carries average price to earnings ratios ranging from close to 48.6 times to close to 58.0 times trailing earnings across these cell and module manufacturing peers. A stock trading meaningfully below its own peer group average, while still posting strong positive return on equity, is a reasonable starting point for a relative valuation screen.
All three companies below clear that bar by a wide margin, with Websol Energy Systems standing out for an exceptionally high return on equity among these solar stocks, despite being the smallest of the three by scale.
The table below lists these three companies alongside their current price, valuation multiple and return ratios.
| Company | NSE Ticker | CMP (Rs) | PE Ratio | Sector PE | ROE | Market Cap (Rs Cr) |
|---|---|---|---|---|---|---|
| Waaree Energies | WAAREEENER | 2,629.50 | 18.94 | 48.56 | 25.71% | 75,825 |
| Websol Energy Systems | WEBELSOLAR | 78.54 | 10.85 | 56.90 | 48.04% | 3,402 |
| Premier Energies | PREMIERENE | 1,006.10 | 27.12 | 58.00 | 35.05% | 45,395 |
Waaree Energies: Largest Scale, Strong ROE
Waaree Energies is India’s largest solar module manufacturer by capacity, supplying photovoltaic modules to utility scale and rooftop solar developers. The stock trades at a price to earnings ratio of 18.94, less than half the sector average of 48.56, at a current price of around Rs 2,630.
Return on equity of 25.71 percent is supported by a debt to equity ratio of 0.22. On an EPS of Rs 139.17 and book value of Rs 501.90, the price to book multiple works out to 5.25.
Websol Energy Systems: Highest ROE, Steepest Discount
Websol Energy Systems manufactures solar cells and modules, operating at a smaller scale than Waaree Energies but with notably strong profitability metrics. Its price to earnings ratio of 10.85 is the steepest discount to its own sector average of 56.90 among these three solar stocks, at a current share price of around Rs 79.
Return on equity of 48.04 percent is by far the highest of the group, and the debt to equity ratio of 0.21 remains manageable. On an EPS of Rs 7.22 and book value of Rs 14.53, the price to book multiple works out to 5.39, broadly comparable to Waaree Energies despite its much smaller scale.
Premier Energies: Integrated Cell and Module Maker
Premier Energies manufactures both solar cells and modules with an integrated production model, supplying customers across India’s growing renewable energy market. The stock trades at 27.12 times trailing earnings, below its own sector average of 58.00, at a current price of around Rs 1,006.
Return on equity of 35.05 percent is the second highest of the three solar stocks, and the debt to equity ratio of 0.86 is the highest among these three names. On an EPS of Rs 36.87 and book value of Rs 94.90, the price to book multiple of 10.54 is the richest of the group.
Valuation Snapshot: PE, PB and Dividend Yield
Beyond the headline price to earnings ratio, book value multiples and dividend yield round out the valuation picture for these three companies. All three currently pay minimal dividends, reflecting continued reinvestment into capacity expansion across the fast growing solar manufacturing industry.
| Company | Price to Book | Book Value (Rs) | Dividend Yield | Debt to Equity |
|---|---|---|---|---|
| Waaree Energies | 5.25 | 501.90 | 0.08% | 0.22 |
| Websol Energy Systems | 5.39 | 14.53 | 0.32% | 0.21 |
| Premier Energies | 10.54 | 94.90 | 0.02% | 0.86 |
Premier Energies trades at the richest price to book multiple of the three, consistent with its integrated manufacturing model and strong return on equity, while Websol Energy Systems pays the highest dividend yield of the group despite its much smaller scale.

Risks to Consider Before Buying These Solar Stocks
A discount to the sector average price to earnings ratio does not remove company specific risk for solar stocks tied to policy and capacity factors.
Policy and Incentive Dependence
Solar manufacturing economics depend significantly on government incentives such as production linked incentive schemes, and changes to these policies could affect future profitability across the industry.
Capacity Expansion and Utilisation Risk
All three companies are expanding manufacturing capacity to meet growing demand, and utilisation shortfalls during the ramp up phase could pressure margins in the near term.
Import Competition and Raw Material Dependence
Solar manufacturers depend on imported polysilicon and wafers for cell production, exposing them to global supply chain and pricing dynamics, alongside competition from lower cost overseas manufacturers.
Valuation Sensitivity to Growth Expectations
Even at a discount to sector averages, these stocks trade at rich price to book multiples, meaning continued strong volume and margin growth is already priced in to a meaningful degree.
How to Track These Solar Stocks
Investors evaluating these three names should track quarterly capacity utilisation, order book additions, and how each sector average PE moves relative to each company’s own multiple over time, rather than relying on the valuation gap in isolation among solar stocks. Comparing these numbers regularly is the most reliable way to judge whether the discount to fair value remains intact or has already closed.

Conclusion
Waaree Energies, Websol Energy Systems and Premier Energies are the three solar stocks currently trading well below their respective sector average price to earnings ratios, while all three post strong double digit return on equity. That combination makes them worth a closer look for investors who already want exposure to India’s solar manufacturing theme, though policy dependence and capacity utilisation risk mean position sizing and diversification still matter when adding these names to a portfolio.
