What is a Solar EPC company?

A Solar EPC (Engineering, Procurement & Construction) company handles the complete delivery of a solar project — from design and equipment sourcing to civil work, electrical installation, grid commissioning, and ongoing operations & maintenance. Sunbuy Renewables is a Solar EPC company based in Vadodara, Gujarat, with in-house teams for all these stages.

What is the OPEX solar model?

The OPEX (Operational Expenditure) solar model — also called RESCO or PPA — lets businesses and institutions use solar power with zero upfront capital investment. Sunbuy Renewables installs and owns the plant; customers pay only for the units consumed, typically at a rate 20–40% lower than grid tariffs.

How much does rooftop solar installation cost in Gujarat, India?

Rooftop solar costs in Gujarat typically range from ₹45,000 to ₹65,000 per kWp depending on system type, panel brand, and inverter. A 5 kW residential system costs approximately ₹2.5–3.5 lakh. Under PM Surya Ghar Muft Bijli Yojana, subsidies up to ₹78,000 are available for systems up to 3 kW. Contact Sunbuy Renewables at +91 93282 81611 for a free site assessment.

Which areas does Sunbuy Renewables serve?

Sunbuy Renewables is headquartered in Vadodara, Gujarat, and serves clients across Gujarat (Ahmedabad, Surat, Rajkot, Bharuch, Anand), Maharashtra, Rajasthan, and pan-India for large utility-scale projects.

What is the lifespan of solar panels installed by Sunbuy Renewables?

Solar panels installed by Sunbuy Renewables carry a 25-year linear power output warranty from Tier-1 manufacturers. Inverters typically carry a 5–10 year warranty. With proper O&M, a well-installed solar plant delivers consistent performance for 25–30 years.

Does Sunbuy Renewables handle solar O&M after installation?

Yes. Sunbuy Renewables has a dedicated Operations & Maintenance (O&M) division offering AMC packages that include remote SCADA monitoring, panel cleaning, preventive maintenance visits, inverter health checks, and guaranteed performance SLAs — ensuring maximum plant uptime and ROI.

What types of solar projects does Sunbuy Renewables handle?

Sunbuy Renewables handles residential rooftop solar (1–10 kW), commercial & industrial rooftop solar (10 kW–1 MW), ground-mounted utility-scale solar power plants (1 MW+), solar carport structures, solar pumping systems, solar street lights, battery energy storage systems (BESS), and EV charging stations.

How a 165 kW Solar Plant Helped Prayosha Healthcare Cut ₹21+ Lakhs in Annual Energy Costs

165 kWp Rooftop Solar System | 35-Day Installation | Ankleshwar, Gujarat

The Challenge

Rising electricity tariffs threaten API manufacturers competing on global prices. Prayosha Healthcare—18 years in pharmaceutical API production and export—needed to reduce operational expenses without compromising product quality.

“”
Sunbuy approached this as a manufacturing problem, not just an installation.

Why This Industrial Solar Project Stood Out

Energy stability drives quality. Unlike typical solar installations, API synthesis demands voltage consistency. Even minor grid fluctuations risk batch contamination. Sunbuy implemented three-phase monitoring to deliver production-grade power, not just cost savings.
Sustainability unlocks export markets. International pharma buyers prioritize suppliers with green credentials. For a 20-country exporter, solar-powered manufacturing becomes a competitive differentiator.
Zero operational disruption. The 35-day timeline fit around production schedules and maintenance windows—critical for continuous manufacturing facilities.

Engineered for Reliability: System Architecture

Three-Phase Inverters: Maintains voltage regulation across all phases, preventing micro-fluctuations that could affect synthesis reactions.
Grid-Tie Integration: Seamless connection with existing supply—zero production interruption, with automatic failover capability.
Real-Time Monitoring: IoT-enabled performance tracking ensures immediate detection of any voltage anomalies or system deviations.
Redundant Design: System architecture prevents single-point failures, enabling maintenance without facility downtime.

Impact by Numbers

✓ ~ ₹ 21.68 L annual cost reduction (electricity savings)
✓ ~ ₹1.80 L monthly impact on production expenses
✓ ~ 2.71 L units annual generation
✓ ~ 3-4 year ROI with depreciation benefits
✓ ~ ₹5 crore+ value over 25 years

Customer Testimonial

“”
Installation was smooth and we started seeing savings from the first bill itself. Our electricity cost has reduced a lot, and it also supports our company's eco-friendly image for exports. SunBuy understood our factory requirements very well.

Why Manufacturing Solar Systems Matter

For pharma, chemicals, food processing, or any industrial facility competing on global prices: controlling energy costs means controlling margins. Solar reduces COGS (Cost of Goods Sold), strengthens pricing power, and builds market resilience.
