  1. Step 1

    Start from the solar template

    Executive summary, scope, deliverables, assumptions, exclusions, schedule, terms and warranty are pre-written.

  2. Step 2

    Enter the system

    kW size, module and inverter lines, structure, cabling, commissioning. Add the battery as an optional line.

  3. Step 3

    Check margin and GST

    Enter your purchase costs privately. Set the GST slab per line and see the breakdown.

  4. Step 4

    Send and follow up

    Branded PDF or a link. Reminders chase the quote until the customer decides.

- Site survey, shadow analysis and structural assessment - Supply of solar PV modules, grid-tied inverter and mounting structure - DC and AC cabling, earthing, lightning protection and protection devices - Installation, testing and commissioning - Net-metering application support with the local DISCOM ([customer to provide documents]) - Handover with as-built drawings and operation guidance

Assumptions

- Roof is structurally sound and accessible for installation - Unobstructed south-facing roof area of approximately [100 sq m] is available - Existing electrical infrastructure can accept the solar connection - Customer provides water and power at site during installation

Exclusions

- Civil works beyond standard module mounting - DISCOM fees, meter charges and statutory deposits - Battery storage (available as an optional item) - Any work not explicitly listed in the scope

Warranty

What a solar customer compares

Residential and small commercial customers usually have two or three quotations in hand. They compare the price per kW, the module and inverter brands, the warranty years and whether net-metering is handled. A quotation that makes those four things easy to find wins attention; one that buries them in a lump sum invites a phone call asking for a breakdown. The template puts modules and structure on per-kW lines, names the brand placeholders in the line details, and has a dedicated warranty section.

Net-metering, subsidies and the DISCOM

The slowest part of most rooftop projects is the paperwork. The template includes net-metering liaison as its own line so the customer sees it is included, lists the documents the customer must provide under assumptions, excludes DISCOM fees and deposits, and warns in the notes that approval timelines depend on the utility. If a central or state subsidy applies, describe it in the notes; because subsidies are usually paid to the customer, the quotation should show the full price.

Margins on a thin-margin business

Module and inverter prices move, and margins are thin. Enter your purchase cost per kW and per unit when you quote, and the margin readout shows whether the deal is worth taking before you send it. The hero document on the homepage is exactly this view, running on the same engine. Costs are never shown to the customer.

From commissioning to invoice

Payment milestones in the template are 40 percent with order, 50 percent on delivery and 10 percent on commissioning. On acceptance, convert the quotation to an invoice for the full amount; the milestones print on it for reference. Add follow-ups for the quote and for the payment dates so nothing goes quiet. See follow-ups and invoices in the help center.
