How to Get Solar Leads7 channels that book site surveys, not tyre-kickers
Bought solar leads get called by five rivals before you dial. Here is how a photovoltaic installer wins residential and commercial clients on its own terms, by zone, by savings, by roof.

Key takeaways
Generate, don't buy: exclusive leads from live data beat shared vendor leads on cost per booked survey
The real edge is the B2B angle: warehouses, car parks, farms and communities of owners with unused roof space
Lead with savings and grants, not panels: the bill cut is what books the survey
Per Vonsel internal data (2026), the trade installers prospect most is businesses with their own premises and high energy bills
To get solar installation clients, focus every channel on one service zone and one offer: a free roof survey. Combine local SEO and reviews, targeted email and phone outreach to high-bill homes and businesses with roof space, door-to-door near finished projects, referrals and electrician partnerships. Lead with savings and grants, not hardware.
That answer hides the real opportunity. Residential solar is crowded and price-driven, but the International Energy Agency reports that solar PV is now the fastest-growing electricity source in the world, and a large share of that growth is commercial and industrial rooftops. The US Energy Information Administration tracks the same surge in photovoltaic system installs. The installers who win in 2026 are the ones who stop competing for the same shared homeowner leads and start mapping every business in their area with a roof big enough to matter.

The channels
7 channels that actually book solar surveys
No single channel fills a solar pipeline. These seven, run together on one zone, are what separate a busy installer from a quiet one:
1. Local SEO and Google reviews
Rank for "solar installer + your city" and keep your Google profile loaded with recent reviews. High-intent buyers search before they call.
2. Targeted email outreach
Email businesses with roof space and high consumption directly. A relevant savings estimate beats any generic blast.
3. Phone follow-up
Call to book the survey after the email lands. Two touches in a fortnight roughly doubles your reply rate.
4. Door-to-door near projects
Canvass the streets around a finished install. Neighbours who can see your work convert far better than cold lists.
5. Referral programs
Pay or reward existing clients for introductions. Solar referrals close fast because trust is already in place.
6. Trade partnerships
Team up with electricians, roofers and builders. Many already field "could I add panels?" questions they cannot serve.
7. Self-consumption webinars
Run a short online session on bills and grants for local business owners. It pre-qualifies the room before any survey.
Buying versus generating is the strategic fork here. We break it down in depth in buy solar leads vs generate them, and the short version is that shared leads rarely beat your own list on cost per booked install.
Map every business with roof space in your area
Search warehouses, car parks, farms and SMEs by city and sector, get verified phone and email for each, and stop sharing leads with five rivals.
Residential pays the bills; commercial builds the business. A 200 kW warehouse rooftop is worth dozens of household installs, and almost nobody is prospecting it well. Build your solar energy and installation leads list around these segments:
Shared roof, grants for collective self-consumption
Property administrator
Car parks and retail parks
Canopy solar plus EV charging upsell
Site or asset manager
Farms and agribusiness
Pumps and cold stores run on expensive grid power
Owner or estate manager
Hotels and cold storage
High, steady year-round load
General or maintenance manager
The unlock is data. You need a list of companies that own their premises, sorted by sector, size and zone, with a contact for each. This is the same B2B prospecting muscle behind getting roofing leads and landscaping clients: find the businesses that need your service, then reach the right person.
The cheapest solar lead is not the one a vendor sells you for $80. It is the warehouse two streets from your last install whose owner has never been pitched, because no installer bothered to map them.
The process
The 6-step process to fill your solar pipeline
Channels are tools; this is the loop that turns them into booked surveys. Run it weekly:
1
Pick a service zone
Draw a radius where install and maintenance trips stay profitable. Concentrate every channel inside it instead of spreading thin across a region.
2
Build a target list
List businesses with roof or land space and high-bill households in your zone. A business finder lets you filter by sector, size and location and pull contacts in minutes, the same way you would find verified business emails at scale.
3
Lead with savings and grants
Open with the bill cut and the available subsidy or tax deduction, not the panels. Decision-makers buy the outcome, and self-consumption grants are often the trigger.
4
Run multi-channel outreach
Email, then call, then knock. The same prospect hearing from you two or three ways in a fortnight is what moves a cold contact to a booked survey. Stay compliant: see cold email without breaking GDPR.
5
Book a free site survey
Make the only ask a no-obligation roof assessment. It is low friction and lets you qualify orientation, shading and real consumption on the spot.
6
Track and route every lead
Log each prospect on a map, group survey visits by proximity, and follow up until they sign, postpone or opt out. Route planning alone can reclaim hours each week.
Stop renting other installers' leftovers. Map your zone, own your list, and the surveys book themselves.

Most solar installers combine local SEO and Google reviews, targeted email and phone outreach, door-to-door canvassing in high-potential streets, referral programs and partnerships with electricians or roofers. The best results come from focusing every channel on one service zone and one clear offer: a free roof survey.
How do I get commercial solar leads?
Build a list of businesses with large roofs or land in your area: warehouses, factories, car parks, farms, cold stores and communities of owners. Filter by sector and size, then approach the facility or operations manager with an estimate of their bill cut and the available self-consumption grant.
Is it better to buy solar leads or generate them?
Bought solar leads are shared with several installers and convert poorly because the prospect is already being called by rivals. Generating your own exclusive list from live business data costs less per booked survey and gives you full control over zone, segment and follow-up timing.
What is the best message to open with for solar?
Lead with the outcome, not the hardware. Reference the prospect's likely energy bill, the percentage they could save, and the current grant or tax deduction. End with a single low-friction ask: a free, no-obligation roof or site survey.
How do I target homeowners likely to want solar?
Prioritise detached and semi-detached homes with south-facing roofs, areas with high electricity consumption, and neighbourhoods where you already have a reference install. Door-to-door near a finished project converts well because neighbours can see the result.
How much do solar leads cost?
Lead vendors charge roughly $30 to $250+ per shared solar lead, and you still pay even when the prospect goes cold. Generating exclusive lists from live data with a business finder starts around €23.95/month for hundreds of contacts, which works out far cheaper per booked install.
Should solar installers do cold email under GDPR?
Yes, B2B cold email to companies with roof or land space is possible under GDPR using legitimate interest. Email the business mailbox, keep the offer relevant to cutting their energy costs, identify yourself, and include a one-click opt-out you honour immediately.
