What does the AI do day to day at a solar energy company?
Solar energy customers always send the same questions: how much a system for their home costs, how long it takes to install, whether it works on cloudy days, whether the roof needs replacing. The AI answers that right away, on the company's WhatsApp, with no waiting line.
It also asks for what the technician needs to put together the quote: average electric bill, roof type, city. With those answers, it already separates people ready to book a visit from people who are just shopping for a price.
- Explains the basics: expected savings, installation timeline, panel warranty
- Collects the electric bill and the address before calling the technician
- Follows up with people who asked for information and went quiet, without pushing a hard sell
- Flags when the case is outside the profile, such as a roof without the structure to support the system
What it doesn't do: calculate the electrical design, size the number of panels or give the final contract price. That remains the work of the engineer or the technical salesperson.
The real math: what it costs and what's included
At CertuAI, the Start plan costs US$ 75 per month and answers up to 1,600 messages with the AI, for up to 5 team members. The Pro plan costs US$ 120 and the Max plan costs US$ 249 per month.
For a solar company, the number that matters is how many repeated messages arrive per month before they turn into a technical visit.
To see what the AI would cost in your business, see how much it costs to put AI in place.
When is it worth it and when is it not?
It's worth it when most of the WhatsApp traffic is the same question coming from different people: price, timing, how it works on cloudy days. The AI handles that without the technician having to stop what they're doing.
It's worth less when almost every request already arrives qualified, with the electric bill and the roof plan in hand, ready to go straight to the engineer. Then the bottleneck is not the initial customer service, it's the visit schedule.
The deciding criterion is this: count how many messages per week are repeated and how many already arrive ready for a quote. If most are repeated, the AI saves time. If most already arrive ready, the gain is smaller.
How CertuAI can help
You connect the WhatsApp number the company already uses, with no setup fee and no minimum contract term. The customer notebook fills itself in: every conversation becomes a contact, a deal and a task, and the AI follows up with people who went quiet up to 2 times, every 24 hours.

Frequently asked questions
- Can the AI calculate the size of a solar energy system?
- No. It collects the basic data, such as the electric bill and roof type, but the technical calculation stays with the engineer.
- Does the AI book the technical visit on its own?
- It organizes the customer's data and flags who is ready, but your team confirms the time of the visit.
