WhatsApp for Rooftop Solar EPC Installers 2026

Net-metering: the approval customers cannot see

Before a rooftop system can export power, the local DISCOM has to approve net-metering — a feasibility check, an agreement, and a bidirectional meter installation, with the process and timelines varying by state and utility. To the homeowner this is an invisible black box that stalls the project for weeks. Pushing the DISCOM application reference and its current stage into the same WhatsApp thread — application submitted, feasibility cleared, meter scheduled, meter installed — turns that black box into a status bar. Your team still does the utility liaison; WhatsApp just relays where it stands so the customer stops calling to ask. This is the same one-tap status-and-SLA pattern a rooftop-plus-EV lifecycle runs across its longer install journey.

Compliance you cannot automate away

These are the reasons a bot must never speak for you on a solar thread. Verify each against the current rule as of 2026 — scheme terms, ALMM/BIS standards, electrical-inspection rules, GST and enforcement all change and vary by state:

PM Surya Ghar — apply on the portal, claim by human

The subsidy runs through the National Portal and is paid by DBT to the customer's account after installation and inspection. Your WhatsApp automation can remind a customer to complete registration, share the document checklist, and report which stage the application sits at — but it must never assert a subsidy amount as guaranteed, never collect bank or Aadhaar details in the chat, and always point to the official portal for the actual claim. A wrong subsidy figure sent in writing is a liability.

ALMM and BIS — approved modules only

Government-subsidised rooftop installations are generally required to use solar modules from the Approved List of Models and Manufacturers (ALMM) and BIS-certified equipment; the eligible list is revised periodically. Share the actual module make, model and certification with the customer on request — the automation sends the real datasheet, it does not invent or paraphrase a certification.

Electrical inspection and safety

Depending on system size and state rules, the installation may need sign-off from the state electrical inspector (CEIG) before commissioning, and the workmanship carries a real safety duty. WhatsApp logs the inspection date and shares the certificate; a human owns the electrical sign-off and any safety call. The thread records the milestone, it never certifies the installation is safe.

GST and pricing

Rooftop solar has a specific GST treatment on equipment and installation services, and the rate and input-credit position deserve a check with your CA rather than an assumption. WhatsApp sends the quotation and payment-stage reminders; it never gives a tax opinion or negotiates a price on its own.

DPDP — homeowner data

A customer's rooftop photo, address, electricity bill and contact are personal data under the DPDP Act, 2023. Keep proof of consent, send only what the homeowner opted into, and give an easy opt-out — which is also exactly what keeps the WhatsApp number healthy. See the DPDP 2026 changes guide.

Capturing the enquiry the first time

Most rooftop leads die in the gap between "I saw your ad" and a booked site survey. A short structured intake on WhatsApp — rooftop photo, pincode, average monthly bill, own house or society — before the lead reaches a salesperson lets you size the system and route it to the right surveyor immediately, tagged by DISCOM area. A homeowner sends a photo and a bill amount; the enquiry lands qualified and ready to quote instead of starting another phone game. Track every enquiry in a WhatsApp CRM so no rooftop goes cold between survey and subsidy.

What it costs on RichAutomate

RichAutomate runs on the official WhatsApp Business API (Meta Cloud API) with ₹0 platform fee, ₹0 setup and ₹0 monthly minimum. You pay per conversation on Meta's category rates: Client Pay at ₹0.10/message plus Meta's per-conversation rate, or SaaS Pay at ₹1.20/marketing and ₹0.30/utility conversation all-in. A promotional or scheme-awareness push is marketing-category; survey confirmations, net-metering status and subsidy-stage updates are the cheaper utility category. A 14-day trial with 100 free credits and no card lets you run one real enquiry-to-quotation cycle before committing. Verify current Meta rates, which change periodically. Full breakdown in the WhatsApp Business API cost guide and Client Pay vs SaaS Pay. Note: going live on the official API in India effectively requires GST for business verification — treat GST as required, not optional.

A realistic 30-day rollout

• Week 1: Number on the official API, business verification underway (GST ready). Build the opted-in list from customers who already enquired or bought — consent logged.
• Week 2: Launch the structured rooftop enquiry intake (photo, pincode, bill, house type) and site-survey slot booking with surveyor ETA.
• Week 3: Wire quotation delivery, DISCOM net-metering status pushes, and the PM Surya Ghar subsidy-stage tracker (status only, portal link for the claim).
• Week 4: Add after-sales — generation-check nudge, AMC renewal reminder, one-tap breakdown ticket. Review which reminders converted and tune timing.

Start with the enquiry intake and the subsidy-status thread — highest return, lowest risk — and expand to after-sales once the thread carries real projects. See the platform in full on features and pricing.

Bottom line

A rooftop solar EPC business is a long anxious journey with a government subsidy at the end, and every stage of it is messaging. Put enquiry capture, site-survey booking, quotation, DISCOM net-metering status and PM Surya Ghar subsidy tracking on WhatsApp, and the "any update?" calls stop. Keep every price, capacity, subsidy amount and safety sign-off human, apply on the official portal not in chat, and work an opted-in customer list — and the number stays healthy while the projects move.
