How it works

Visualize. Design. Solarize.

Three steps from an address to a design your customer can say yes to.

  1. 1

    Visualize

    See the site in 3D

    Search an address or drop a pin, and get a 3D model of the rooftop or open ground.

  2. 2

    Design

    Lay out the panels

    Place panels on the real site, clear of tanks and stair rooms, and watch the system size.

  3. 3

    Solarize

    Show what it saves

    See the energy and ₹ savings for the year, then share the design and win the job.

Accurate by design

Clean energy starts with a design you can trust

Every design is simulated hour by hour through a typical year of weather at its exact location, with shadows traced against your 3D model, so the numbers you quote hold up on site.

What does "projects up to 50 kW" mean?

Each project (one site you design) can have a solar system of up to 50 kW on Starter, or 500 kW on Pro. A typical home system is 3 kW, so Starter covers homes, shops and smaller housing societies. There's no limit on how many projects you design.

How will I be billed?

Monthly or yearly, in Indian rupees, through Razorpay. Paying yearly costs 20% less than paying month by month. You can pay with UPI Autopay, a credit or debit card, or a netbanking e-mandate. 18% GST is added to the plan price and shown before you pay.

Can I get a GST invoice for my business?

Yes. Add your company name and GSTIN at checkout so they can be included on your invoices.

Can I change or cancel my plan?

Yes. You can move to a bigger plan, or between monthly and yearly billing, from your dashboard at any time. If you cancel, your plan stays active until the end of the billing period you've already paid for.

What if I design projects bigger than 500 kW?

Talk to our sales team about an Enterprise plan. You'll get custom project sizes, volume pricing, and a dedicated account manager.
