Borosil Renewables halves rooftop solar revenue target to ₹36 crore
First-year target cut 50% from ₹75 crore, while 600 TPD expansion revenue pushed to FY28, despite strong core glass margins of 35%.
What's new
- Q1 FY27 sales ₹405.69 cr, up 53% YoY; EBITDA ₹142 cr at 35% margin.
- 600 TPD expansion on track for Q4 FY27 commissioning but revenue modeled from April 2027.
- Rooftop solar revenue target halved to ₹36 crore; Q1 revenue only ₹1.3 crore.
Themes from the call
Demand
Full 1,000 TPD capacity utilization with 8% volume growth; domestic market structurally undersupplied with 75% demand gap.
Margins
35% EBITDA margin driven by ASP of ₹160.30/sqm (including ₹9.50 fuel surcharge) and operating leverage; surcharge gains transitory.
Capital allocation
600 TPD expansion funded via internal accruals and selective debt; next growth project decision within 5-6 months. Rooftop solar is low-margin adjacency.
Guidance watch
- 600 TPD expansion: commissioning in Q4 FY27 but revenue only from April 2028; incremental EBITDA ₹80-85 cr from 60% volume increase.
- Rooftop solar: FY27 internal target ₹36 crore revenue at single-digit EBITDA margins.
- Long-term revenue: ₹2,500 crore to ₹4,000 crore-plus by FY30.
- Fuel surcharge: Rs 9.50/sqm being gradually reduced as energy costs normalize; no permanent ASP uplift.
Risk flags
- Customer concentration: top 10 accounts represent 65-68% of volume; module industry consolidation in 12-18 months.
- Fuel surcharge transitory: base pricing must hold without surcharge to sustain margins.
- Rooftop solar ramp: Q1 revenue of ₹1.3 cr implies need for sharp acceleration to hit ₹36 cr target.
- Expansion revenue delay: no contribution until FY28, two years from now.

The brief
Borosil Renewables delivered a strong Q1, with sales up 53% to ₹405.69 crore and EBITDA margins hitting 35%, but the call was dominated by two cuts to prior guidance. The first was a 50% reduction in the rooftop solar first-year revenue target, from ₹75 crore to ₹36 crore. Q1 rooftop revenue was just ₹1.3 crore. Management described the business as nascent, but the scale of the revision signals a slower ramp than anticipated. The second was the 600 TPD expansion timeline: in May, management hinted at possible Q4 FY26 revenue; in July, they advised modeling revenue only from April 2027. The core glass business remains robust — full capacity utilization, structural undersupply (75% of demand unmet), and government tariff protection — but the contradictions on the new ventures erode confidence in guidance fidelity. The fuel surcharge of ₹9.50/sqm is being trimmed as energy costs normalize, so future margin expansion must come from volume and productivity, not pricing. With customer concentration high and module overcapacity looming, the expansion will be tested. Borosil's core is solid, but the promises on new growth are fraying.
Borosil's core glass business is shining, but the rooftop solar pivot is off to a slow start and expansion revenue is a year away.
