● FAQ

All frequently asked questions

What is solar EPC?+

Solar EPC (Engineering, Procurement and Construction) means one contractor owns feasibility, design, equipment supply, installation, grid connection and commissioning. GALILEO delivers turnkey plants so sponsors have a single accountable counterparty from site to COD.

What is the typical timeline for a solar EPC project?+

Residential systems: 4–8 weeks after permits. C&I rooftops: 2–4 months per site. Utility-scale: 9–14 months from NTP to COD depending on scale and grid scope. Hybrid solar+BESS adds 1–2 months for EMS integration and compliance testing.

How do I choose a solar EPC contractor?+

Evaluate delivered capacity, performance ratio track record, safety (TRIR), in-house vs subcontracted scopes, grid interconnection experience and post-COD O&M guarantees. Ask for reference plants in Gujarat or Rajasthan and a bankable yield model before NTP.

How do I get in touch with GALILEO?+

Use our contact form or email us directly. We respond within 48 hours with next steps for qualifying inquiries.

What warranties does GALILEO provide?+

Module warranties per manufacturer (typically 25 years). GALILEO provides a 2-year EPC defect warranty on utility projects, 10-year workmanship on C&I and residential, plus optional long-term O&M with performance ratio guarantees.

Which markets does GALILEO operate in?+

GALILEO operates across Gujarat and Rajasthan. Hub cities are Ahmedabad (Gujarat) and Jaipur (Rajasthan). We also deliver in Surat, Vadodara, Rajkot, Gandhinagar, Jamnagar, Jodhpur, Udaipur, Kota and surrounding districts.

How much does residential solar cost?+

Typical home systems (3–15 kW) vary by roof complexity and DISCOM tariff. Use our solar calculator for an instant estimate, or request a site survey for a firm quote including permits and interconnection.

Am I eligible for PM Surya Ghar subsidy in India?+

Eligible residential consumers in India may receive central subsidy under PM Surya Ghar for grid-connected rooftop systems. GALILEO handles DISCOM application and net-metering paperwork on qualifying projects in India.

What is the payback period for home solar?+

Most residential systems we install achieve 4–6 year simple payback against retail tariff, net of incentives. Actual payback depends on consumption profile, tariff structure and local subsidies.

What size commercial solar system do I need?+

We model 15-minute load curves against PV output and right-size arrays to your tariff — typically maximizing self-consumption before export. Commercial sites range from 50 kW to 5 MW per location.

Can solar be installed without shutting down operations?+

Yes. GALILEO phases C&I installs around shift changes and maintenance windows. Our median production downtime on operating facilities is zero hours.

Is my factory roof strong enough for solar?+

Every industrial engagement starts with structural assessment and stamped drawings. We design ballasted or penetrating mounts based on roof class, wind zone and membrane warranty requirements.

Can industrial solar include battery storage?+

Yes. We engineer DC and AC coupled BESS for peak shaving, demand-charge reduction and backup power expansion, integrated with your plant MV infrastructure.

What is a bankable yield model?+

A P50/P90 energy yield report per IEC standards that lenders accept for project finance. GALILEO issues PVsyst-based yield certificates reconciled against as-built at handover.

Who owns grid interconnection on utility-scale projects?+

GALILEO self-performs substation design, MV collection, protection coordination and grid-code compliance testing up to 220 kV as part of the EPC envelope.

What financing options exist for solar EPC projects?+

Capex (balance sheet or project finance), power purchase agreements (PPAs), leases, and green loans. Residential and C&I may qualify for PM Surya Ghar, accelerated depreciation and state-level GEDA/RRECL incentives.

What ROI can I expect from commercial solar?+

Typical C&I projects target 12–18% unlevered IRR against retail or blended tariffs. Utility-scale returns depend on PPA price, CapEx and resource quality — we model scenarios in the feasibility study.
