How it works

Understand the building. Design the right system. Operate it well.

A plain-language view of how rooftop solar supplies a building, and the five steps Entler follows on every project.

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.

Implementation process

From first conversation to operating system.

Understand the building. Design the right system. Choose the right commercial model. Deploy. Operate.

  1. 01

    Discover

    Understand electricity bills, rooftop, building requirements and objectives.

  2. 02

    Assess

    Conduct site assessment and analyse electricity consumption.

  3. 03

    Propose

    Develop the system size, commercial model and project economics.

  4. 04

    Deploy

    Complete approvals, installation, commissioning and handover.

  5. 05

    Operate

    Monitoring, maintenance and ongoing performance support.

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
₹—To be calculated from your building’s data

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 We do not publish indicative savings without analysing your data.
