Integrated solar and storage

Solar and storage, engineered so energy stays on

Terragreen designs, builds and services integrated solar and battery storage systems as one engineered solution for industrial manufacturing, data centres and telecom networks. We size systems around your actual load profile, backup requirements and operating environment—lowering your energy cost while protecting continuous operations.

A Terrakraft India company. Storage-first engineering powered by domestic manufacturing. Documented 1,000-site deployment record delivered by sister brand Zyntra (October 2026).

  1. Dawn. Your plant runs on a schedule. The sun doesn't. At dawn, the grid carries the load.
  2. Midday solar. Solar runs the production line directly, and the surplus charges LFP storage instead of being exported.
  3. Grid failure. When the grid drops, storage picks up the load in under 20 ms. The plant keeps running.
  4. Evening peak. As the sun sets, stored solar covers the most expensive tariff hours.
  5. Storage-first. We size storage to your load and backup need first, then design solar and the grid interface around it.
  6. One team. One accountable team, from single-line design to service. Energy that stays on.
The electrical reality

Solar is the easy part. Keeping the power on is the work.

Standard solar installations generate when the sun shines, but production schedules run around the clock. When clouds roll in or the utility grid drops, unintegrated solar cannot hold plant voltage. Bridging that gap requires three engineering disciplines:

01

Continuity

Unplanned outages and power cuts halt production lines and cost millions in downtime. Solar alone shuts down during grid failure; storage maintains continuous autonomy.

02

Integration

Generators, UPS units, and solar must synchronize cleanly at the plant bus. We engineer protection and fast transfer in sub-20 ms windows without voltage sag or frequency instability.

03

Accountability

When components fail, solar and battery vendors blame each other. Terragreen provides one team from single-line design through commissioning, warranty, and lifetime maintenance.

Our method

Storage-first engineering

Most contractors calculate how many solar panels fit on a roof and treat the battery as an afterthought. We reverse the process. We evaluate your load curves, startup surges, and outage risks first, configure the battery storage around your exact duty cycle, and then design the solar generation and grid interface to support it.

01

Your Load & Backup Need

15-min interval profiling, inductive motor surges, and tariff structure.

02

Storage Sized First

Chemistry, C-rate, and autonomy configured to your exact duty cycle.

03

Solar & Grid Designed

Array sized for daytime loads and battery recharge capacity.

04

One Integrated System, One Team

Single accountable EPC delivery, protection coordination, and performance monitoring.

Sector solutions

Tailored around the demands of your industry

Industrial campus with a ground-mounted solar array and a container battery yard
Manufacturing & C&I

High grid tariffs and maximum demand charges erode margins. We install captive ground and rooftop solar-plus-storage to displace daytime grid consumption and shave peak surges.

Data centres

Power continuity is non-negotiable. Load growth from compute clusters must fit your existing power path without violating uptime standards.

Action line

Arrange a technical workshop on load interfaces and redundancy.

Documented field record

1,000 sites. One installation standard.

Delivering infrastructure across India requires repeatable execution. Sister company Zyntra supplied, installed, and commissioned Lithium Iron Phosphate (LFP) energy storage across 1,000 government-building sites along a 600 km corridor in Uttar Pradesh (Documented, October 2026).

What the 1,000-site record proves to prospective clients
  • One Standardized DrawingPre-engineered conduit runs, enclosures, and gland entries.
  • Cluster-Based DeliveryCloned, regional field crews executing repeatable handovers on time.
  • Rigorous Quality AuditsTime-stamped GPS photographs and mounted metal handover plaques.
  • High-Ambient ReliabilityProven operation in unconditioned spaces reaching +45 °C ambient heat.

This deployment proves our group's ability to execute complex, multi-site programs to a single standard. It does not replace site-specific validation for data centres or telecom networks—which Terragreen proves on your infrastructure through technical workshops and controlled field pilots.

FAQs

Frequently asked questions

Still deciding where to start? Talk to an engineer about your site.

What is storage-first engineering?

We evaluate your 15-minute load profile and backup requirement first, configure the battery storage capacity to that exact duty cycle, and then design the solar array and grid connection around it.

Does Terragreen only install Zyntra batteries?

No. We choose equipment on technical and commercial merit. Zyntra is proposed where configurable domestic manufacturing offers the best fit. Any group relationship is disclosed in writing in our equipment schedule.

Which sectors do you serve across India?

Commercial and industrial manufacturing plants, data centres, and telecom tower portfolios, alongside utility-scale generation parks and independent operations and maintenance (O&M) contracts.
