Maximize ROI – Solar Solutions for Warehouses & Logistics

Scale your operations cost-effectively with large rooftop solar systems designed for warehouses, distribution centers, and logistics facilities. Generate revenue from unused roof space.

Why Solar for Warehouses & Logistics?

Warehouses and logistics facilities represent some of the largest untapped solar potential in India. Expansive roof areas combined with consistent daytime operations create ideal conditions for maximizing solar generation and ROI. Additionally, large flat roofs impose minimal structural challenges.

Massive Roof Space

Warehouses typically have 1,000-10,000+ sq meters of roof. Perfect for MW-scale systems.

Exceptional ROI

Large systems achieve 30-40% annual returns on investment. Quickest payback period.

Occupancy Correlation

Peak solar generation matches peak warehouse operations (8 AM - 6 PM). Optimal utilization.

Revenue Generation

Excess solar generates net metering credits, creating additional revenue stream.

Sustainability Appeal

Attracts global customers seeking carbon-neutral supply chain partners. ESG compliance.

Asset Monetization

Roof space, which was unused, now generates income for 25+ years.

Grid Integration & Net Metering for Large Systems

Seamless Integration with Grid Infrastructure

For systems above 100 kW, additional technical considerations apply:

Three-Phase Connection

Large systems use 3-phase connection
Requires specialized net meter (3-phase capable)
Load balancing across phases important
MSEDCL coordination essential

Technical Standards Compliance

Frequency stability (49-51 Hz window)
Voltage stability (±10% deviation limit)
Power factor requirement (0.95 leading/lagging)
Harmonic distortion limits (IEEE standards)

Capacity Payment

Some boards charge “connection capacity charges” for large systems
Typically ₹100-200 per kW annually
Offset by solar generation savings

Distribution Transformer Upgrade

If facility transformer undersized, upgrade may be required
Cost: ₹5-15 lakhs depending on capacity
Shared with multiple facilities if possible

Export Limitation

Some distribution areas limit max export to grid
Check local MSEDCL guidelines
System designed within these limits

Frequently Asked Questions

Will installing solar on my warehouse affect the roof warranty?

No. Modern mounting systems don’t penetrate deep roof. Roof integrity maintained. Actual roof warranty typically unaffected.

Can I expand system capacity later?

Yes. Most systems designed with expansion capability. Adding capacity 3-5 years later is cost-effective.

What if my warehouse has a rented space?

Roof lease model perfect. Third party invests; you receive lease income. No capital required. Ideal for rented facilities.

How does solar affect warehouse temperature?

Solar panels provide insulation, reducing cooling load by 5-10%. Actually helps keep warehouse cooler in summer.

Can I sell excess solar energy?

Excess fed to grid via net metering and credited to account. Cannot directly sell to others currently (regulations).

What if my warehouse operates 24x7?

Daytime consumption covered by solar. Night operation from grid. With battery backup, 24/7 operation is possible.

Is my roof structurally capable?

Most warehouse roofs designed to support solar. We conduct free structural assessment to confirm.

What's the maintenance burden?

Minimal. Quarterly panel cleaning and annual inspections. We handle everything through maintenance contract.

How does this impact my insurance?

Typically no issue. Inform insurer; may slightly increase coverage. Usually not a concern for warehouses.

Can I integrate with my existing energy systems?

Yes. SCADA system integrates with facility management, lighting systems, HVAC controls.
