Automate WhatsApp & Instagram for Your Solar Installation Company with ZapUp
Every inquiry starts with subsidy questions under schemes like PM Surya Ghar, and the sales cycle from first message to signed installation involves multiple site-survey and follow-up touchpoints that are easy to lose track of manually.
Quick answer
ZapUp answers common subsidy and rooftop-size questions on WhatsApp and Instagram, books site-survey visits automatically, and sends structured follow-ups through the long sales cycle so leads don't go cold waiting for a callback. It also keeps customers updated on discom net-metering and installation milestones after the sale.
Watch it handle a real conversation

WhatsApp & Instagram automation for your solar installation company: the practical guide
Every day brings a fresh wave of 'PM Surya Ghar subsidy milegi kya' messages, and somewhere between the tenth enquiry and the site visit you were supposed to schedule, a lead goes cold. You're searching for how to send bulk WhatsApp marketing messages for your solar business because calling each rooftop enquiry back one by one isn't keeping up with the volume.
This guide covers running compliant broadcast campaigns to past and current leads, sizing a system from a customer's electricity bill photo, booking site surveys without back-and-forth, following up through the multi-week decision cycle, sending net-metering and installation updates as process information, scheduling post-installation maintenance reminders, and switching over cleanly if you're already on AiSensy, Wati, Gupshup or Interakt, without losing your number or your approved templates.
Where the money leaks right now
✗Bulk enquiry replies buried under one-by-one calling
Rooftop leads from Instagram and referral WhatsApp groups pile up faster than one salesperson can call back, so the ones who don't get a same-day reply assume you're not interested and message a competitor installer instead.
✗kW sizing conversations stall waiting on a bill
A customer asked to 'send your last electricity bill' over a call often never does, because there's no easy way to just snap a photo and send it — so the sizing and quote conversation dies before it starts.
✗Long decision cycle loses leads to silence
Solar decisions take weeks of comparing quotes and subsidy math, and if no one nudges the lead during that gap, they either forget about you or sign with whoever followed up last.
✗Post-installation service and cleaning reminders skipped
Panels need periodic cleaning and inverter checks, but once the installation is billed and closed, there's rarely a system reminding either the customer or your team, so annual maintenance revenue goes uncollected.
How to set it up, step by step
- 1
Get verified and set the subsidy-aware greeting
Apply for the WhatsApp Business API with a verified business profile so rooftop leads see your company name, not a random number. Set the greeting to acknowledge PM Surya Ghar subsidy questions directly, ask for rooftop area or monthly unit consumption, and offer to size a system from an electricity bill photo before booking a survey.
- 2
Size the system from a bill photo, not a guess
Ask the customer to send a photo of their latest electricity bill; use the monthly unit consumption on it to suggest a rough kW range and ballpark cost band, clearly marked as an estimate pending a site survey. Never promise subsidy approval or final pricing at this stage — that depends on the survey and the discom.
- 3
Book the site survey and confirm the visit window
Once the customer is interested in a size range, collect their address, roof type and approximate rooftop area, then book a survey slot and confirm the surveyor's arrival window on WhatsApp the day before. Anything about structural feasibility, shading or exact panel count waits for the surveyor's on-site assessment, not the chat, and gets flagged for a human to follow up.
- 4
Follow up through the decision cycle automatically
Set scheduled follow-ups for leads who've seen a quote but haven't responded in a few days — a gentle nudge, not a repeat pitch — so the multi-week comparison period doesn't go silent on your side. Track which stage each lead is at, from first enquiry to quote sent, so the follow-up tone matches. Route any lead asking detailed technical questions to a human immediately.
- 5
Send milestone and service-due updates after the sale
After installation, send stage updates as process information — installation date, inspection scheduled, net-metering application submitted to the discom — without promising approval timelines you don't control. Later, use the same number to remind customers about annual panel cleaning or inverter health checks, and to notify them when a service technician is on the way, so post-sale service feels as organised as the sales process was.
Sending bulk marketing messages on WhatsApp
Bulk WhatsApp messages for a solar business work best aimed at people who've already shown interest — past enquiries who didn't convert, existing customers due for a service visit, and your area's electricity-bill audience during subsidy scheme updates. Send a new subsidy slab announcement, a seasonal push before summer bill shocks drive search volume, or a maintenance reminder batch to everyone installed over a year ago, rather than one generic blast to your entire contact list.
- 📣PM Surya Ghar subsidy update — new slab details, book a free survey
- 📣Summer bill season reminder: size your rooftop system from your last bill
- 📣Annual panel cleaning and inverter check-up booking for existing customers
- 📣New battery storage add-on now available for existing rooftop customers
- 📣Net-metering documentation reminder for customers whose installation is complete
Do this the right way
Broadcasts only reach customers who've opted in, and any promotional message outside a live conversation has to be sent as a template Meta approves in advance, including subsidy updates and maintenance reminders. Messaging numbers that haven't engaged with you hurts your quality rating and can lower your daily messaging limit, so build your list from real enquiries.
What this looks like in practice
Illustrative scenarios showing how the flows above behave — not accounts of specific businesses.
A Sunday evening with five subsidy questions in one hour
Five different numbers ask about PM Surya Ghar eligibility within the same hour after an Instagram reel goes up. The agent answers each with the same subsidy process information, asks for rooftop area or a bill photo, and books three of them straight into site-survey slots for the coming week, leaving two flagged for a human because they asked about commercial rooftop financing.
A customer who sends a blurry bill photo
A customer sends a photo of their electricity bill that's hard to read clearly. The agent asks for the units-consumed line specifically, gets a clearer reply, and shares a rough kW range and cost band marked as an estimate pending an actual site check. The customer books a survey for the coming weekend to confirm the real number before deciding anything.
A lead who went quiet after receiving a quote
A customer received a quote two weeks ago and stopped replying. A scheduled follow-up checks in gently, asking if they have questions, without repeating the sales pitch. They respond asking about net-metering timelines, the agent shares what the process generally involves without naming a date, and the lead re-engages, finally booking the survey they'd been putting off.
Best practices
✓Never promise subsidy approval or a timeline
Subsidy eligibility and disbursement depend on the discom and the scheme's own processing, not on you. Share what the process generally involves and let the customer apply through the right channel — promising approval erodes trust when it doesn't happen.
✓Treat the bill photo as an estimate input, not a quote
A unit-consumption number from a bill gives a rough kW range, but shading, roof orientation and structural load need an actual survey. Label every bill-based number as an estimate so no one holds you to it before the visit.
✓Keep following up through the whole decision cycle
Solar leads often take three to six weeks to decide between quotes. Space out follow-ups instead of one-and-done, and stop only when the customer asks you to, so a slow decision doesn't read as a lost lead.
✓Separate sales broadcasts from service reminders
A customer who already bought doesn't want another sales pitch in their maintenance reminder, and a new lead doesn't need a cleaning-service nudge. Keep these as separate template categories so each message lands as relevant, not spam.
Mistakes to avoid
✗Quoting a final price before the site survey
Giving a firm number based only on a bill photo, before shading, roof type and cabling distance are checked on-site, sets an expectation the actual quote won't match, and the customer feels misled when the number moves.
✗Promising subsidy approval to close the sale
Telling a hesitant customer 'subsidy is guaranteed' to push them toward booking creates a problem you can't fix later — approval and disbursement timelines are the discom's call, not the installer's, and customers remember who promised what.
✗Letting post-installation leads go cold on the discom step
Net-metering approval takes time and customers call repeatedly asking for status. Not sending a proactive process update makes it look like you've disappeared after getting paid, even when the delay is entirely on the discom's end.
Already on AiSensy, Wati, Gupshup or Interakt? How to switch
If you're currently running campaigns through AiSensy, Wati, Gupshup or Interakt, that's not a wrong choice — they're solid broadcast and flow-builder platforms many solar installers start on. The reason to move is that a long sales cycle needs an agent that can actually answer a subsidy or sizing question and book the survey, not just fire a scheduled campaign or a rigid click-tree.
Step 1. Migrate your existing WhatsApp number
Your business number moves to ZapUp through Meta's official provider-migration process, keeping the same number and chat history your leads already have saved. Plan for a short downtime window during the switch and schedule it outside your peak enquiry hours.
Step 2. Export your leads and opted-in contact list
Pull your full lead list, including who's opted in to marketing messages, from your current platform before switching, since you can only broadcast to contacts who've consented. This becomes your base list for subsidy updates and maintenance reminders on ZapUp.
Step 3. Re-create and re-submit your approved templates
Subsidy update announcements, quote-follow-up messages and service reminders approved on your old provider need to be recreated and resubmitted for Meta's approval under the new provider — they don't transfer automatically. Budget a few days before your campaigns can go live again.
Step 4. Run parallel for a cycle before switching fully
Keep the old platform active for ongoing conversations while ZapUp takes new enquiries, so no lead in the middle of a multi-week decision falls through. Once bookings, follow-ups and reminders are confirmed working on ZapUp, disconnect the old number there.
Discovery happens on Instagram — ZapUp runs both
Solar installers get discovery through Instagram posts about subsidy schemes and savings calculators; ZapUp captures those DM inquiries and keeps following up automatically through the naturally long decision cycle instead of losing leads to silence.
Solar Installation Company WhatsApp automation: your questions answered
Can I automate WhatsApp bookings for my solar installation business?
Yes. ZapUp answers common subsidy and cost questions, books site-survey visits, and sends scheduled follow-ups on WhatsApp so leads in the long sales cycle don't go cold.
How do I follow up with solar leads who don't respond right away?
ZapUp can send automatic scheduled follow-up messages to leads who haven't replied in a few days, keeping the conversation alive through the typical multi-week decision period without manual chasing.
Can I update customers automatically after installation on net-metering status?
Yes, you can send milestone updates on WhatsApp covering installation date, inspection, and net-metering approval status, so customers aren't calling to check progress after the sale.
How to send bulk marketing messages on WhatsApp for my solar panel business?
You need the WhatsApp Business API and Meta-approved marketing templates, sent only to contacts who've opted in. ZapUp lets you build the customer list from your enquiries and send subsidy updates, seasonal pushes or maintenance reminders as a batch, tracked against your daily messaging limit and quality rating.
What does WhatsApp automation for a solar installation business cost?
Pricing is quoted for your business: a one-time setup and platform fee, then a monthly fee based on your conversation volume, channels and team seats — all in US dollars. Every plan is deployed with the full funnel built, from ad entry points through qualification, follow-ups and retention; Meta’s own per-conversation charges are passed through at cost. Write to sales@zapup.marketing or book a demo for a quote within one business day.
Can a WhatsApp bot for my solar business talk in Hindi or reply in Hinglish?
Yes, ZapUp replies in the same Hindi-English mix your team already uses with rooftop customers, not stiff formal English. You set the tone and standard answers once, and every subsidy, sizing, survey and follow-up reply follows that same style automatically, without sounding like a translated script.
Can WhatsApp automation tell customers if they're eligible for the solar subsidy?
It can share general PM Surya Ghar eligibility and process information — what the scheme usually covers, how the application generally works — but it never promises approval or a disbursement date, since that depends entirely on the discom and scheme rules, not the installer.
How do I get the WhatsApp green tick for my solar company?
The green tick comes from Meta's official business verification, checking your registered business details against your Business Manager account. It's not required to run WhatsApp automation — quote replies, survey bookings and follow-ups work on an unverified number too, though verification adds visible trust for cold leads.
Can I size a rooftop solar system from a customer's electricity bill on WhatsApp?
Yes, customers can send a photo of their bill, and the agent reads the units-consumed figure to suggest a rough kW range and cost band, clearly marked as an estimate. The final size and quote still need an actual site survey before anything is confirmed.
