A rooftop solar customer signs up full of enthusiasm, and then waits: for the DISCOM feasibility approval, the subsidy application, the structure, the panels, the net meter, the commissioning. Every silent week in that stretch is a week the customer wonders whether they made a mistake. Solar EPCs and installers use WappBlaster on the official WhatsApp Business Platform to fill that silence with useful status updates, and to stop sending surveyors to roofs that were never going to qualify.
Solar installers screening a WhatsApp lead before the surveyor drives out
A site survey costs a technician's half-day and fuel. Many rooftop enquiries, especially those from social media ads, come from tenants, people with shaded or asbestos roofs, or households whose bill is too low for the system to pay back. A short chatbot conversation filters these out first:
- Do you own the property? (Yes / No / Housing society)
- Roof type: RCC flat, sloped tin sheet, other.
- Average monthly electricity bill, as a range.
- Your DISCOM and city.
- Photo of the roof and a recent bill (optional, but it saves a visit).
Qualified leads are assigned to a sales person in the shared inbox with all five answers visible. Housing society enquiries can route to a separate team, since the decision process is entirely different. You can build this flow without code in WappBlaster's automation builder.
The solar installer's project tracker, sent to the customer on WhatsApp
Between signed order and a working system, a residential project passes through steps the installer does not fully control. Turn each step into a utility template triggered when your project manager updates its stage in the CRM:
| Stage | Message carries |
|---|---|
| Survey completed | Proposed capacity, layout image, next step |
| DISCOM application filed | Application reference, what the DISCOM checks |
| Feasibility approved | Expected installation week |
| Material dispatched | Panel and inverter make, delivery day |
| Installation complete | Photos of the array, warranty documents as PDFs |
| Net meter installed and commissioned | Commissioning date, how to read the inverter app |
| Subsidy status changes | Where the application is under PM Surya Ghar, and what the customer must do |
If your CRM is Zoho, HubSpot, Salesforce or LeadSquared, stage changes can fire these directly; see the Zoho CRM integration guide for how that wiring works.
Solar installer WhatsApp updates when nothing has happened
The hardest message to write is the one where the DISCOM has not replied. Send it anyway. "Your net metering application is still with the DISCOM. This step usually takes a few weeks in your area; we will message you as soon as it moves." A customer who hears that every ten days is far less likely to call, cancel or post a complaint than one who hears nothing.
Solar installers keeping paperwork findable on WhatsApp
Warranty cards, the commissioning report, the net meter agreement and subsidy receipts get lost in email. Sent as PDFs in the same thread as the project updates, they are in one place when the customer needs them for a bank, a home sale or a warranty claim years later.
Bulk WhatsApp for solar customers after handover
Set up a drip sequence that starts on the commissioning date: a cleaning reminder before the dusty months, a monsoon check message, an annual service offer, and a referral request once the customer has seen a few low bills. Only the last two are marketing messages, and only for customers who agreed to receive them. A mid-size installer's cost for all of this is the ₹7999 ($200) yearly WappBlaster licence plus Meta's own per-message charge, which is billed unmarked.
Where solar installers go wrong on WhatsApp
- Broadcasting "save 100% on your bill" style claims to cold lists.
- Promising subsidy timelines the DISCOM or ministry controls.
- Sending generation "reports" with numbers you are not actually measuring.
- Letting the sales number go silent after the advance is paid; that is when the customer needs updates most.
