Phone Systems for Solar Panel Installers

Answer every enquiry while demand is booming, keep sales and aftercare apart, and put the business number on every surveyor's phone

Demand for solar is high. Your phone has to keep up

UK homes are installing solar in record numbers. Government data reported by Solar Power Portal showed nearly 172,000 solar installations in 2026 by September. For installers, that means more enquiries, more surveys and more customers ringing about systems you have already fitted.

Most homeowners contact several installers before choosing one, and the first to answer and book a survey usually wins. SwitchboardFREE makes sure every enquiry reaches someone, whether your team is in the office, in a customer's kitchen or up on a roof.

What a solar installation company gets

  • Separate sales and aftercare lines: new enquiries and existing customers each reach the right team
  • Call queuing for busy weeks: callers hear their place in the queue rather than an engaged tone
  • Surveyors and installers on the same number: the SwitchboardFREE app on every mobile, showing the company number
  • Every missed lead followed up: voicemail to email with transcripts, and missed call alerts
  • Calls logged in your CRM: HubSpot, Pipedrive, Salesforce and more, or webhooks for your own system
From £5 per user/month + VAT

Sales and aftercare, kept apart

As your installed base grows, so do aftercare calls: an inverter showing an error, a battery not charging, a question about export payments. Those customers deserve a quick answer, but they should not tie up the sales line. Give them their own option or their own number, ringing the engineers who know the systems, with its own voicemail and opening hours.

Feature by feature: why SwitchboardFREE works for solar panel installers

Every SwitchboardFREE account comes with over 40 features. These are the ones that make the biggest difference to solar panel installers, and why.

DepartmentsStandard & Unlimited plans
A solar company's phone carries new enquiries, survey bookings and aftercare calls about inverters and batteries. "Press 1 for a quote, press 2 if you already have panels with us" sends each caller to the right team, so a homeowner ready to buy never waits behind a support call.
Call queuing and queue position announcements
Enquiries arrive in waves when energy prices make the news. Instead of an engaged tone, callers wait in a queue and hear their place in it, so they hold on rather than ringing the next installer on the comparison site.
Music on holdStandard & Unlimited plans
Callers waiting for the sales team hear music rather than silence, which tells them they are still connected. It also covers the moment a surveyor puts a customer on hold to check roof measurements or panel specs.
Divert calls to your mobile
Surveyors spend the day in customers' homes and installers spend it on roofs. The business number rings the SwitchboardFREE app on their mobiles, so the right person can answer wherever they are, and calls they make show the company number.
Voicemail to email
When nobody can answer, the caller's message arrives in your inbox as audio with a written transcript. The office can read a lead's address, roof type and questions and book the survey without playing back a recording.
Missed call alerts
Solar leads go cold quickly because homeowners usually contact several installers. The caller's number is emailed the moment a call is missed, so the sales team can ring back within minutes.
Ring groups
Ring every salesperson at once so the first free person answers, or ring the office first and the surveyors next. Aftercare calls can ring the engineers who know the systems you have installed.
Call recordingPaid add-on
System sizes, battery options, export tariffs and prices are often discussed on the phone. Recording sales calls gives you a record of what was quoted and promised, which helps with disputes and with training new sales staff.
Local and national numbers
Use a local number for each area you cover and a national 03 number for regional advertising. Put a different number on each lead source and your call logs show which campaigns actually produce calls.
CRM integrations and webhooks
Log every call in HubSpot, Pipedrive or Salesforce automatically, or use webhooks to push call details into your own lead system. Nobody has to type up who rang and when.
Time-of-day routing
Homeowners often ring about solar in the evening and at weekends. Route those calls to a salesperson on the late rota, or to voicemail with a message promising a call back first thing.
Unlimited UK callsIncluded on Unlimited
Solar sales means a lot of outbound calls: following up quotes, confirming surveys and booking installs. On the Unlimited plan your team can call UK landlines and mobiles without counting minutes (fair use applies).

Questions solar installers ask us

Yes. On the Standard and Unlimited plans, a short menu such as press 1 for a quote and press 2 for existing customers sends each caller to a different team, each with its own voicemail. You can also use a separate number for aftercare.

Yes. Calls ring the SwitchboardFREE app on their mobiles, and calls they make from the app show the company number rather than their personal one.

Callers wait in a queue and hear their position, with music on hold on the Standard and Unlimited plans, and anyone who leaves a message has it emailed to you with a transcript. Missed call alerts give you the number of anyone who hung up.

Yes. SwitchboardFREE can log calls in HubSpot, Pipedrive, Salesforce, Capsule, Google Sheets and Microsoft To-Do, and webhooks can send call details to any other system.
