How the best solar installers sell, from enquiry to switch-on

Follow one deal from the first enquiry to the smart meter spinning backwards, and the difference between the installers who win consistently and the ones who wonder where the job went is rarely the price. It is a set of habits, repeated at every stage. Here is the whole journey, stage by stage, the way the best operators in the Irish trade actually run it.

1. The enquiry: won or lost in the first hour

A fast, organised first response is the first proof of professionalism the homeowner ever sees, and a slow one is read, fairly or not, as a preview of how the install will go. The best operators also qualify before anyone drives anywhere: the Eircode, which pins down the county and the local solar irradiance that the savings figures depend on, and the year the home was built, because a house built and occupied before the end of 2020 qualifies for the €1,800 SEAI grant and a newer one does not. Two questions, and the conversation is already grounded in their actual house.

2. Before the visit: walk in already knowing

The professionals look at the property on satellite imagery before they arrive: the roof orientation, the usable faces, roughly how many panels fit. They walk in knowing that a south facing roof at a 30 to 40 degree tilt is the ideal, that an east west roof still delivers 80 to 85% of optimal and is well worth doing, and that a north face is usually a polite no. That preparation changes the whole conversation. Instead of "can we do this?", the kitchen table starts at "here is what your roof can do, let us talk about what that is worth to you".

3. The kitchen table: usage first, technology second

The discovery that matters is about when the house uses electricity, not what is on the roof. Does anyone work from home? Do the washing machine and dishwasher run by day or by night? Is there an EV or a heat pump, or one coming? Those answers decide the system size, the battery question and the honest savings figure, so the best sellers ask them before they talk about a single panel. The technology explanation stays simple: the panels make the power, the inverter makes it usable in the house, the smart meter counts what goes back to the grid.

And one physical check that separates the professionals: look at the fuse board. If it is an old pre-RCD consumer unit, a €400 to €700 safety upgrade is mandatory before solar can be connected. The best operators flag it on the spot, honestly, as the safety requirement it is. The average ones miss it or bury it, and detonate the customer's trust when it surfaces later.

4. The recommendation: sized to the usage, honest about the battery

The sweet spot for a typical Irish three bed semi is 3.5 to 4.5 kW, eight to ten panels, and the discipline is to size to the household's usage, not to fill the roof because the space is there. An oversized system on a low usage home just exports more, and export pays a fraction of what self consumption saves.

The battery conversation is where honesty visibly wins deals. A 5 kWh battery runs €1,700 to €4,500 and can push the payback out by three to five years. Out at work all day? A battery probably makes sense, it banks the daytime generation for the evening. Home all day using the power as it is made? Often it does not, and saying so, plainly, buys more trust than any discount. The professional middle path: fit a hybrid inverter as standard so the system is battery ready the day battery prices make the maths work.

5. The proposal: the same evening, in writing, three money lines

A verbal price or a vague text is a red flag to an educated homeowner. The winning version is a detailed written proposal, delivered fast, ideally on the spot or the same evening while the conversation is still warm. It shows the three money lines, gross cost, 0% VAT confirmed, the €1,800 grant deducted, net cost, and then it tells the 25 year story: the units the roof will generate, what self consumption saves against grid electricity at around 35c a unit, and what the surplus earns under the Clean Export Guarantee at 15c to 32c. The homeowner should be able to hand it to their most sceptical relative and have it survive. The full anatomy of that document is in our guide to quoting solar that wins.

6. Objections: answer them straight

• "It's too expensive." Reframe it as what it is: an investment returning the equivalent of 11 to 16% a year, with a standard payback of five to seven years and twenty plus years of largely free electricity after that. Few things they own return that.
• "I'll wait for prices to drop." Be honest: panel prices have stabilised, it is battery prices that are falling. So fit the panels and a hybrid inverter now, lock in the current grant and the 0% VAT, and add the battery in a few years when its maths improve. Waiting only forfeits savings.
• "Does solar even work in cloudy Ireland?" Yes. Modern panels run on daylight, not sunshine, and an ordinary 4 kW system generates over 3,800 units a year here. The proof is the record numbers of Irish homes installing.
• "I'm getting other quotes." Welcome it, genuinely. Then arm them: make sure the cheaper quote includes scaffolding, the ESB notification and the grant admin, and check the warranty lengths. Cheap quotes are usually cheap because something is missing, and the homeowner who goes checking usually comes back.

7. The follow-up: where deals actually die

Most lost deals are not lost to a competitor, they are lost to silence. The installer who sends a comprehensive written proposal immediately, and then stays reachable for the technical questions that surface three days later at the kitchen table, stands out against the one who gave a price and disappeared. The follow-up does not need to be clever. It needs to exist, be prompt, and make the next step obvious.

8. The close and the paperwork: take the burden, set the clock

The close itself is quiet: a 10 to 20% deposit, balance on completion, and never full payment up front. Then the professional takes the whole administrative load: the SEAI grant application, the NC6 form to ESB Networks, the scheduling. And expectations get set honestly: the physical install is one to two days, but grant approval and grid notification put the real timeline at four to eight weeks from enquiry to generating, stretching to ten or twelve in the busy season. A customer who knows that up front is patient; one who finds out late is furious.

9. After the switch-on: turn one job into three

The handover is the last selling moment: the safety file, the warranties, the manual, and steering the homeowner to the post works BER assessment that releases their grant money. Then the ask, while the delight is fresh: the review and the referral. In a trade where the average registered installer already carries a 4.7 star rating, reviews are the pipeline, and the operators who ask for them systematically turn one happy roof into the next three enquiries.

The thread running through it

Look back over the nine stages and the pattern is plain: speed, preparation and honesty, repeated. Answer fast, walk in knowing the roof, ask about the life not the hardware, size honestly, put it in writing the same evening, answer objections straight, follow up, take the paperwork, and ask for the referral. None of it is a trick. All of it compounds. The installers who run this whole journey inside one system, where the Eircode, the assessment, the proposal, the follow-up and the schedule flow into each other instead of living in five different places, simply get more of it done per deal. That, as it happens, is exactly what Caolú was built for.
