A message to a solar installer often starts with one line: how much is solar for my house. A real quote needs a load list and a roof. This page shows how an AI agent handles the first part of that conversation and where your engineer comes in.

Can an AI agent answer WhatsApp for a solar installer?

Short answer

Yes. An AI agent can answer the first questions about solar on WhatsApp: what a system costs, what it can power, how long the battery lasts, the warranty and whether you install in the area. It collects the appliance list and the location, and it leaves the final quote and the site visit to your team.

What do customers ask a solar installer on WhatsApp?

Eight questions that reach a solar company, each with an example reply. Nobody real sent these messages: they were written for this page, and each package name, price and warranty period is a [placeholder] you replace with your own.

  1. 1. How much is solar for my house?

    Customer

    How much is a solar system for a three-bedroom house?

    AI agent

    It depends on what you want to run. Our packages start at [starting price] for [package name], which powers [what it powers]. Which appliances do you want on solar, and for how many hours a day?

    How the agent answers: It gives the starting price from your package list and then asks for the load. It does not invent a final price for a house it has not seen.

  2. 2. What can the package power?

    Customer

    Can [package name] carry a fridge, a TV and a water pump?

    AI agent

    [Package name] is sized for [appliances it covers]. A water pump needs [larger package]. I will leave your list here for our engineer to confirm before you pay anything.

    How the agent answers: Each package entry says what it runs and what it does not. The agent matches the list of the customer against that entry and goes no further.

  3. 3. Backup time at night

    Customer

    How long will the battery last when the power goes off?

    AI agent

    With [package name] and the load you listed, the battery is sized for about [backup hours]. The real figure depends on what is switched on, so our engineer confirms it after the site visit.

    How the agent answers: It repeats the backup figure you wrote for that package and says clearly that the load changes it.

  4. 4. Do you install in my town?

    Customer

    I am in [customer town]. Do you come here?

    AI agent

    We install in [areas you cover]. For [customer town] there is a travel charge of [travel charge]. Is the system for a house, a shop or an office?

    How the agent answers: The service area and the travel charge are one entry. A town outside the list gets a plain no, with the nearest place you do cover.

  5. 5. Paying in instalments

    Customer

    Can I pay in instalments?

    AI agent

    Yes, we offer [payment plan] with [deposit] paid upfront. The terms are in [terms document]. Approval is done by [person name], so I cannot approve it in this chat.

    How the agent answers: It explains the plan in the words you wrote. Approving credit is never the job of the agent.

  6. 6. Warranty

    Customer

    What warranty do you give?

    AI agent

    The panels carry [panel warranty], the inverter [inverter warranty] and the battery [battery warranty]. Our own workmanship is covered for [workmanship period].

    How the agent answers: Four warranty lines, one for each part, copied from what you taught it. It does not stretch a warranty to cover damage the terms leave out.

  7. 7. Asking for a site visit

    Customer

    When can you come and check my roof?

    AI agent

    Site visits are on [visit days]. The visit costs [visit fee]. Send me your address and a day that suits you, and [engineer name] will confirm it with you here.

    How the agent answers: It gives the visit days and the fee and collects the address. The engineer confirms the day, because the agent does not know the route of the team.

  8. 8. A fault on an installed system

    Customer

    My inverter is showing a red light and making noise.

    AI agent

    Sorry about that. A fault needs our technician, so I will not guess. Please write the message shown on the inverter screen and your installation address, and [technician name] will reply here.

    How the agent answers: It does not diagnose. It collects the error text and the address so the technician starts with the facts.

What must a solar installer teach the agent?

A solar sale is a technical sale, so the agent needs clear edges. Give it your packages as fixed facts and tell it where its answers end.

  • Packages and prices. One entry per package: the name you sell it under, what it powers, the backup time you stand behind, the price, and whether installation, cabling and mounting are included.
  • Service area. The towns where you install, the travel charge for each zone and the places you do not go.
  • Hours and site visits. Visit days, the visit fee, whether the fee comes off the final price, and how long it usually takes from deposit to installation.
  • Warranty and brands. The brand and the warranty of the panels, the inverter and the battery, your workmanship cover, and what makes a warranty void.
  • What it must never promise. An exact saving on the electricity bill. A backup time before the load is known. That a package will run an appliance that is not on its list. An installation date before stock is confirmed. Credit approval. A life with no outage at all.

What should the agent hand to a person at a solar company?

If a customer asks for a human, the agent passes the conversation to you and tells you. If your engineer starts typing to that customer, the AI stays out of that chat. Beyond that, teach it to collect the facts and wait for a person in these cases:

  • The final quote, once the appliance list and the hours of use are in the chat.
  • Any fault report, and at once if the customer mentions heat, a burning smell or sparks.
  • Approval of an instalment plan.
  • A shop, a clinic, a school or a farm: larger jobs need a visit before any number is given.
  • A warranty claim or a complaint about an installation.
  • Questions about the roof itself: its age, its strength or who repairs it after mounting.

What does an AI agent on WhatsApp cost a solar installer?

CertuAI has two plans that a small business usually chooses between. Start costs $75 a month and covers up to 1,600 AI replies a month on one WhatsApp number. Pro costs $120 a month and covers up to 5,000 AI replies a month on 3 WhatsApp numbers. Plans are in US dollars, paid by card, month by month with no contract.

You connect the number you already use, so your customers keep writing to the same WhatsApp. Every WhatsApp chat becomes a contact in the built-in CRM. 30-day money-back guarantee: if you do not like it within 30 days, you get 100% of your money back.

A solar enquiry is long. One customer may send many messages about appliances before a quote is possible, and each answer the agent sends counts as one reply. An installer who advertises should count messages, not customers, when choosing between the two plans.

Questions people ask

Can the AI agent size a solar system for a customer?

It should not. The agent can match a list of appliances to the packages you described, because you wrote what each package runs. Sizing a system for a real house, with its roof and its wiring, is the work of your engineer after the visit.

Will the agent quote a solar price I did not approve?

It answers from the prices you gave it. Give it starting prices for each package and the rule that a final price comes only after the load list and the site visit. With that rule written down, it has no number of its own to offer.

What if a customer sends the appliance list late at night?

The agent answers at any hour. It asks for what is missing, usually the hours of use and the town, and the complete list waits in the conversation. In the morning your engineer opens one chat with everything needed for the quote.

What about people who ask the price of solar and then disappear?

The agent answers them, so your engineer does not spend the day on price checks. Each of those chats becomes a contact in the built-in CRM, with the town and the package they asked about, and your team decides who is worth writing to again.

Should the agent answer fault reports from customers who already bought?

Only to collect the facts: the message on the inverter screen, the address and what happened before the fault. It should not tell anyone to open a unit or touch the wiring. A technician replies in the same chat.
