Solar Pumps Stocks in India

4-Factor Sector Score

An additive sector-relative research score. The four displayed point contributions always equal the total: Growth & earnings (35), Capital efficiency (25), Valuation (20), and Relative strength (20). Missing or stale evidence is absorbed inside the affected factor, never applied as a hidden adjustment.

Missing observations are not scored as bad. Their missing weight lowers confidence and pulls the final score toward neutral. PEG is guarded: positive earnings, positive 5–60% three-year EPS growth, and a positive P/E are required.

Revenue Scale & Growth Durability

Shakti Pumps (India) Ltd has the highest Revenue among the 3 Solar Pumps companies compared here, at ₹2,934 crore. Oswal Pumps Ltd is next at ₹2,065 crore. GK Energy Ltd has the highest Revenue growth at 56.7%, so level and change sit with different companies. 3 of 3 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Shakti Pumps (India) Ltd is the scale leader at ₹2,934 crore, 42.1% ahead of Oswal Pumps Ltd. GK Energy Ltd's growth is 56.7% from a ₹1,716 crore base, with 12 reported observations in the 20-quarter window. Treat the growth leader as an acceleration candidate, not as equally proven scale.

Investor read: Shakti Pumps (India) Ltd is the scale benchmark; GK Energy Ltd is the acceleration watch. Promote the challenger only if growth persists and converts into margin and returns.

This conclusion weakens if: Shakti Pumps (India) Ltd's growth falls below GK Energy Ltd's for two consecutive comparable reports while operating margin also compresses.

Operating Economics & Margin Trend

Oswal Pumps Ltd has the highest OPM among the 3 Solar Pumps companies compared here, at 23%. GK Energy Ltd is next at 18%. GK Energy Ltd has the highest Margin change at -1 percentage points, so level and change sit with different companies. 3 of 3 companies report a comparable reading, the latest through Mar 2026.

What the numbers say: Oswal Pumps Ltd leads opm at 23%; GK Energy Ltd leads margin change at -1 percentage points.

Investor read: Oswal Pumps Ltd sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

This conclusion weakens if: The next two comparable reports reverse the current margin change signal.

Oswal Pumps Ltd has the highest Net profit among the 3 Solar Pumps companies compared here, at ₹378 crore. Shakti Pumps (India) Ltd is next at ₹213 crore. GK Energy Ltd has the highest Profit growth at 52.2%, so level and change sit with different companies. 3 of 3 companies report a comparable reading, the latest through Mar 2026.

What the numbers say: Oswal Pumps Ltd leads with ₹378 crore of TTM profit, 77.5% above Shakti Pumps (India) Ltd. GK Energy Ltd shows 52.2% growth from a ₹204 crore profit base. Compare the size of the base and persistence before ranking acceleration above profit scale.

Investor read: Oswal Pumps Ltd sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

This conclusion weakens if: The next two comparable reports reverse the current profit growth signal.

Capacity Spending & Returns On It

Oswal Pumps Ltd has the highest CAPEX among the 3 Solar Pumps companies compared here, at ₹12 crore. GK Energy Ltd is next at ₹2 crore. The same company also holds the highest CAPEX intensity, at 3.3%. 2 of 3 companies report a comparable reading, the latest through Mar 2026.

What the numbers say: Oswal Pumps Ltd reports ₹12 crore of CAPEX; Oswal Pumps Ltd has the highest covered intensity at 3.3%. Coverage is only 2 of 3 companies and 7 reported observations, so this is partial evidence—not a complete sector rank.

Investor read: Use the CAPEX rank as a diligence queue. Verify commissioning, utilization, cash conversion and post-investment ROCE before treating spend as value creation.

This conclusion weakens if: CAPEX rises without higher utilization, operating cash flow or incremental returns.

Debt Load & Balance-Sheet Headroom

GK Energy Ltd has the lowest Gross debt among the 3 Solar Pumps companies compared here, at ₹206 crore. Oswal Pumps Ltd is next at ₹237 crore. The same company also holds the lowest Net debt, at ₹238 crore net cash. 3 of 3 companies report a comparable reading, the latest through Mar 2026.

What the numbers say: GK Energy Ltd has the clearest covered balance-sheet capacity with ₹238 crore net cash and gross debt of ₹206 crore. Absolute debt alone does not identify the strongest balance sheet because company scale differs; net debt and debt-to-equity carry more information.

Investor read: Prioritize net-cash capacity and leverage relative to operating scale, not the smallest absolute rupee debt.

This conclusion weakens if: Net debt rises faster than revenue and profit for two consecutive reported periods.

Return On Capital Employed

GK Energy Ltd has the highest ROCE among the 3 Solar Pumps companies compared here, at 41.4%. Oswal Pumps Ltd is next at 38.2%. Shakti Pumps (India) Ltd has the highest ROCE change at -26 percentage points, so level and change sit with different companies. 3 of 3 companies report a comparable reading, the latest through Mar 2026.

What the numbers say: GK Energy Ltd leads ROCE at 41.4%, 3.2 percentage points above Oswal Pumps Ltd. Shakti Pumps (India) Ltd has the strongest latest improvement at -26 percentage points. Read the leader beside the density of its reported history: a sparse high return is a candidate; a repeated high return is evidence of durability.

Investor read: GK Energy Ltd sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

This conclusion weakens if: The next two comparable reports reverse the current roce change signal.

What the numbers say: Oswal Pumps Ltd has the lowest comparable Guarded PEG at 0.26×, 58.7% below GK Energy Ltd. Only 3 of 3 companies pass the guard, so no broad “cheapest stock” conclusion is defensible unless the current multiple, own-history position and growth durability agree.

Investor read: Treat valuation as permission to investigate, never as a standalone reason to buy.

This conclusion weakens if: The next two comparable reports reverse the current p/e signal.

This conclusion weakens if: The next two comparable reports reverse the current p/bv signal.

What can make this comparison misleading?

This Solar Pumps comparison names 5 specific ways its own evidence can mislead, all listed below. All 3 companies here report on comparable dates, so no rank carries a stale marker. 1 of the 8 ranked sections has fewer than three usable current readings. A high growth rate can still be a low-base artefact.

Which companies are included?

All 3 companies in the canonical Solar Pumps membership are listed below, largest market value first — nothing is silently dropped, even where a company reports too little to rank. The charts above default to a selective view; this register is the complete set, with each company's own latest reporting date beside it.

AHEAD means the company is beating the index by 5% or more over three months. LAGGING, FUNDAMENTALS UP means it is 20% or more behind over a year while its trailing twelve-month earnings grew 20% or more. Both rules are fixed and applied the same way in every sector.

How was this comparison built?

This comparison is built from the reported filings of 3 Solar Pumps companies, normalized to a common ₹ scale and a shared quarter axis of up to 20 quarters each. Fundamentals run through Jun 2026 and market data through 2026-07-24. A second data feed fills gaps only after identity and scale reconciliation, and missing observations are never interpolated.

A second feed is read only after its reported income is matched against the primary source on at least three overlapping periods. Where the two agree the figures fill silently. Where there is too little shared history to compare, the figures are still drawn — they are the only evidence there is — and marked ⚠ unverified everywhere they appear. Where the two are known to disagree, nothing from the second feed is drawn and the affected company is named under the chart it is missing from. Every company's standing is listed in the register above.
