  • Warehouses & industrial buildings

What we do

A practical rooftop-solar partner for buildings.

  • 01

    Design

    Solar designed around your building

    We assess the available rooftop, electricity consumption and load profile to determine a suitable solar system size.

  • 02

    Finance / Commercial Structure

    Choose a structure that fits your requirements

    Depending on project economics and eligibility, projects can be structured through CAPEX, RESCO or Hybrid arrangements.

  • 03

    Operate

    Support beyond installation

    Entler focuses on monitoring, maintenance and long-term system performance — not simply installation day.

Financing and RESCO availability depend on project economics, customer/credit profile, applicable regulations and final commercial agreements.

How we help

The objective is simple: reduce avoidable grid electricity purchases.

Every recommendation starts from how your building actually uses electricity.

  • Lower electricity costs

    Generate a portion of your electricity locally through rooftop solar.

  • Make better use of your rooftop

    Turn an under-used rooftop into a productive energy asset.

  • More predictable energy costs

    Generate electricity at the building instead of relying entirely on grid purchases.

  • Flexible commercial options

    Choose between CAPEX, RESCO or Hybrid structures where suitable.

  • Less operational hassle

    Entler can support monitoring, maintenance and long-term system performance.

How the system works

Your building uses the solar power first.

A simple way to picture it: the rooftop becomes your building’s first source of electricity during the day, and the grid fills in whatever is left.

  1. SunDaylight hours
  2. Rooftop solarGenerates electricity
  3. Building loadUses solar first
  4. GridSupplies the balance
Solar electricity is consumed on-site first. The grid connection remains in place and supplies whatever the building still needs.
  1. 01

    Solar generation

    Solar panels installed on the building’s rooftop generate electricity during sunlight hours.

  2. 02

    Building consumption

    Solar electricity is used by the building’s active electrical loads.

  3. 03

    Grid balance

    When solar generation is lower than the building’s electricity requirement, the grid supplies the difference.

  4. 04

    Monitoring

    System performance can be monitored to understand generation and operating performance.

Who we serve

Is your building suitable for rooftop solar?

Check Your Building

  • RWAs & Apartment Communities

    Common-area loads such as lifts, pumps, lighting and shared facilities.

  • Commercial Buildings

    Offices and commercial spaces with steady daytime electricity demand.

  • Hotels & Institutions

    Hotels, hospitals, schools and campuses with meaningful consumption.

  • Warehouses & Industrial Buildings

    Large, unobstructed roof areas paired with operational loads.

The right system depends on your electricity consumption, rooftop availability, electrical infrastructure and project economics.

Commercial models

Three ways to structure a solar project

Different buildings have different capital preferences. Entler can evaluate the commercial structure that best fits the project economics and customer requirements.

  • CAPEX

    Customer invests

    CustomerProject entity
    • Customer funds the system
    • Customer owns the system
    • Customer receives the generation savings
    • Suitable where the customer wants asset ownership

  • RESCO

    Entler / project entity invests

    CustomerProject entity
    • Project entity invests in the system, subject to financing and project suitability
    • Project entity owns/operates the system
    • Customer pays for solar energy/service under an agreed structure
    • Reduces or avoids upfront customer capital requirement where available

  • HYBRID

    Investment is shared

    CustomerProject entity
    • Customer and project entity share investment
    • Ownership follows the agreement
    • Savings and costs are structured between the parties

The appropriate model depends on site economics, electricity consumption, customer profile, financing availability, regulations and final contractual terms. RESCO and Hybrid availability is not guaranteed for every project.

Why Entler

Built around the customer’s energy problem — not just the equipment.

  1. 01

    Customer-first system design

    We start with the building’s electricity requirements rather than pushing a standard system size.

  2. 02

    Commercial flexibility

    CAPEX, RESCO and Hybrid structures can be evaluated depending on project suitability.

  3. 03

    Long-term orientation

    Our focus extends beyond installation to system performance and ongoing support.

  4. 04

    Clear project economics

    We use actual electricity data and site information before presenting project economics.

  5. 05

    Practical execution

    From assessment to deployment and operation, the process is designed to remain simple and transparent for the customer.

Project economics

Every project starts with your actual electricity data.

We calculate project economics from your building’s actual electricity consumption, proposed system size, generation estimate, tariff, project cost and selected commercial model.

Project size
—kWTo be calculated from your building’s data
Monthly savings
₹—To be calculated from your building’s data
Annual savings
₹—To be calculated from your building’s data
Lifetime savings

Final numbers depend on tariff, generation estimate, consumption profile, system cost, financing and selected commercial model. We do not publish indicative savings without analysing your data.
