OFF GRID SOLAR

About Solarwaala

Solarwaala is born out of the passion to de-escalate pollution and escalate the adoption of mass solar. Two like-minded environment pros from IIT Bombay started Solarwaala in 2020 as a two-member pack. Now, we’re the 3rd largest EPC contractor for residential installations in India. We’ve helped 25,000+ homes go solar and have been helping our customers save up to 90% on their monthly electricity bills. We install both on-grid and hybrid solar systems. In the near future, we will start the installation of off-grid solar systems too. Some of the services that have set us apart from other vendors include the following.

  • We offer free solar consultation services
  • We use premium-quality prefabricated mounting structures that are resilient and durable enough to handle cyclonic wind speeds reaching up to 170 kmph
  • We offer easy, 10-minute loan approval
  • Our solar consultants and design team procures a 3D model of how solar would look on your rooftop within 15 minutes of the site survey
  • We offer many EMI schemes; zero-cost being the most popular one
  • We offer a 5-year AMC contract
We’re on a mission to build a legacy brand that values its customers the most.

    Overview of an off grid solar system

    An off-grid solar system is also known as a stand alone solar system. Why? Because it’s not connected to the grid. It works as an isolated island of its own. An off grid solar power plant is an intricate setup of the following components.

    • Solar panels (modules)
    • Mounting structures
    • Batteries
    • Solar charge controller
    • Solar inverter
    • Solar accessories

    Off grid solar components and their working

    01

    Solar panels

    Solar panels are made up of solar cells. When they’re made of one single silicon crystal, the resulting panel is monocrystalline. When they’re made of multiple silicon crystals, the resulting panel is polycrystalline (multicrystalline).

    02

    Solar inverter

    The power from solar panels is in the form of direct current. Home appliances run on AC power. This is where the solar inverter comes into the picture. It converts DC power into AC power. An off grid solar inverter, just like an on-grid inverter, is the heart of the solar system.

    03

    Batteries

    Off grid solar functions on batteries. During the sunshine hours, the electricity that the panels are producing is used to run the house. Whatever is extra is used to charge the batteries. That same power from the battery is then used to keep the house running at night.

    04

    Charge controller

    The charge controller in off grid solar controls the charge. It’s in parallel with the solar inverter. The panels produce electricity that goes into the charge controller. It’s the charge control that feeds power into the inverter as well as uses the extra units to charge the batteries.

    05

    Mounting structures

    You have the panels and the inverter, but without proper mounting structures, the system cannot be set up. The mounting structures should be at a proper tilt angle (near perpendicular to the sun for as long as possible) so that they receive maximum sunlight.

    06

    Solar accessories

    You know the major components of an off grid solar system but there are other accessories without which the system will not be safe. Here are the accessories we’re talking about:
    • DC cables and DC combiner box
    • AC cables and AC combiner box
    • MC4 connectors
    • Earthing strips and conduit trays
    • Lightning arrester
