THE SHORT ANSWER
Modelled solar panel job values in Spain run EUR 5,050 to EUR 10,100 in 2026, midpoint EUR 7,550. That midpoint carries 18 to 28 percent gross margin, which is EUR 1,350 to EUR 2,100. Winning the customer takes 3 to 5 exclusive leads at EUR 100 to EUR 150 each, so acquisition costs EUR 250 to EUR 700 and absorbs 11.5 to 49.6 percent of the margin on a single project.
Job value is the number every other commercial decision divides into, which is why roughly right beats precisely wrong. Below is a 2026 band for solar panel projects in Spain and, more usefully, what happens when you divide it: margin on the midpoint job, and what winning that job costs before a single tool comes off the van.
A narrower average would be more comforting and less true, because system size in kilowatt-peak, whether a battery is included, and roof complexity all move the number materially. The market adds its own layer: in Spain, click prices are noticeably below the Benelux baseline, but average job values are lower too, so the ratio of cost per lead to job value is not automatically better.
The numbers, at a glance
Typical project value: EUR 5,050 to EUR 10,100 for a standard solar panel job in Spain, midpoint around EUR 7,550
Gross margin: 18 to 28 percent of contract value, which is EUR 1,350 to EUR 2,100 on the midpoint job
Cost to win one customer: EUR 250 to EUR 700 in lead spend, assuming 3 to 5 exclusive leads per signed job at EUR 100 to EUR 150 each
Acquisition as a share of margin: 11.5 to 49.6 percent of the gross margin on a single job, before any repeat or referral value
Where the solar panel number comes from in Spain
Everything here is a complete installed job for a private household, excluding VAT and excluding competitively tendered work. Emergency repairs are excluded too: urgency prices on availability rather than on scope, and mixing the two produces an average that describes neither.
Inside that definition the spread comes from system size in kilowatt-peak, whether a battery is included, and roof complexity. Spain is a market of roughly 48 million people, which is the pool every one of those quotes is written into.
Around EUR 5,050 for the simple version of this job on an accessible property.
Around EUR 7,550 for the version most quotes describe, including the upgrades customers ask for once they have seen the first price.
Around EUR 10,100 once scope, access or specification all move in the same direction.
Why the average solar panel job misleads
Averages in this trade are pulled upward by a small number of large projects. If three jobs in twenty come in near EUR 10,100, the mean stops describing the work you actually do and starts describing the work you occasionally win.
That matters commercially because acquisition budgets are set as a share of margin. Set them against an inflated mean and you overspend on every ordinary job to break even on the rare large one. The median of twenty signed contracts is the number to use, and in a band of EUR 5,050 to EUR 10,100 it usually sits below the midpoint of EUR 7,550 rather than above it.
Where the margin actually sits in a solar quote
Modules have been priced as a commodity since 2023 and the homeowner can check that line against a wholesaler in ninety seconds. The margin sits in what they cannot price: the mounting system, the DC and AC cabling, inverter selection, the work at the consumer unit and the design itself. Installers who discount to win usually take a percentage off the whole quote, which strips margin out of the labour lines that were carrying it. Holding the installation lines and letting the module line float with the market protects the same contract value with a much better outcome.
What is actually left after materials and labour
Strip materials and installation labour out of a solar panel contract in Spain and 18 to 28 percent remains. On the EUR 7,550 midpoint that is EUR 1,350 to EUR 2,100, and it is the only figure on this page with any bearing on whether a marketing budget is affordable.
Two businesses with identical turnover can therefore have completely different capacity to buy work. Before comparing your acquisition spend with anyone else's, convert it into a percentage of gross margin. Ten percent is conservative, 20 percent is normal, and above 30 percent you are financing growth out of next year's profit, which is a legitimate decision but should be a decision rather than an accident.
What happens to Spanish prices when a segment suddenly opens
Spain has run the same cycle several times and it is worth recognising early. A rule changes or a subsidy lands, demand jumps, the trade fills with new entrants inside two seasons, and the bottom of the price band collapses while the top holds. Solar is the clearest recent example: Royal Decree 244/2019 removed the penalty on self-consumption and simplified registration, the market grew fast, and within a few years margin at the cheap end had been competed away. The businesses still standing after each of these cycles did the same thing, which was to sell a specified job with documentation, guarantees and a named aftercare route rather than the smallest compliant version at the lowest number. Assume any Spanish segment that is currently profitable and easy to enter will be neither in three years.
Break-even on a block of 25 leads
A single lead price is hard to judge. A block is not. 25 exclusive leads cost EUR 1,750 and should convert into 5 to 8 signed solar panel jobs at a midpoint of EUR 7,550 each, which is EUR 37,800 to EUR 60,500 of work booked and EUR 6,800 to EUR 16,950 of gross margin.
Break-even therefore arrives inside the first job. The useful question is not whether EUR 70 per lead is expensive in the abstract, but what happens to that arithmetic if your conversion is half the modelled rate, because that is the scenario worth planning for.
The building stock is built for heat, and that reshapes the job mix
Much of the Spanish housing stock was built for a warm climate: limited insulation, single or early double glazing, and aluminium frames without thermal breaks. That produces a different set of high-value jobs from Northern Europe, where shading, ventilation and cooling matter as much as heating, and window replacement is sold on comfort in August rather than draughts in January. It also means the theoretical saving from a retrofit is large, which is a strong argument, and that the baseline you are replacing is usually lower than a Dutch or German installer would assume.
Batteries move average job value more than any other option
Storage is the single biggest lever on solar contract value. A 5 to 10 kWh domestic battery adds roughly EUR 3,500 to EUR 7,000 to a job that started near EUR 8,000, fitted by the same crew on the same visit, so almost none of the mobilisation cost repeats. Attach rates vary enormously between installers selling identical hardware, from under 15 percent to more than half, and the difference is nearly always whether the battery appears as a priced line on the first quote or as something to discuss later. Quote it as a line the customer removes, not one they have to request.
Raising job value beats cutting lead price
Lead prices move by a few percent when you negotiate. Job value moves by tens of percent when you sell the right scope. For solar panel work the reliable lever is a battery, which adds roughly 40 to 70 percent to the contract value on the same site visit. On the EUR 7,550 midpoint, a 20 percent increase in scope is worth about EUR 1,500 of extra contract value, which is more than the entire acquisition cost of that customer.
Quote the full scope, not the requested scope. Present the minimum job and the complete job as two priced options on the same document.
Bundle work the mobilisation already pays for. Scaffolding, access and travel are sunk the moment you are on site.
Anchor high, then subtract. A customer removing items from a complete quote finishes above a customer adding items to a minimal one.
Sell the monthly figure. Finance changes which end of the solar panel band a household considers realistic.
Five numbers to pull from your own accounts this week
Median contract value across the last twenty signed solar panel jobs in Spain, taken from invoices rather than from quotes.
Median gross margin on those same twenty, after materials and installation labour but before overheads.
Total enquiries received in the same period, counting the ones that never answered the phone, so the ratio is honest.
Median time from enquiry to first call attempt, which is the variable that moves cost per customer furthest.
Acquisition cost as a percentage of median gross margin. That single percentage is what you compare across suppliers, markets and years.
How these figures were built
These figures are a benchmark model, not a survey. They combine an industry base range observed across Western European home-improvement campaigns with a country multiplier for local auction pressure. Treat them as a band to negotiate against, not a quote. Job values here start from an industry band for solar panel and are scaled by a construction cost index for Spain of 0.72 against a Benelux baseline of 1.00. That index tracks labour and materials, deliberately separate from the advertising auction multiplier used on our cost-per-lead pages, because the two move independently.
How Flock Leads prices this
For comparison against the acquisition figures above, this is what Flock Leads charges for exclusive volume in this market:
Starter - 10 leads for EUR 750, which is EUR 75 per lead
Growth - 25 leads for EUR 1,750, which is EUR 70 per lead
Scale - 45 leads for EUR 2,925, which is EUR 65 per lead
Pro - 70 leads for EUR 4,340, which is EUR 62 per lead
Max - 90 leads for EUR 5,400, which is EUR 60 per lead
No retainer, no contract term, and no lead sent to a second business. Unused volume rolls over under the Flock Lead Promise.

Frequently asked questions
How much does a solar panel project cost in Spain?
Between EUR 5,050 to EUR 10,100 for a private household in 2026, midpoint around EUR 7,550, excluding VAT and excluding competitively tendered work. Where a specific job lands depends on system size in kilowatt-peak, whether a battery is included, and roof complexity.
Does this figure include VAT?
No. Every number here is exclusive of VAT, because rates on home improvement work vary by country, by measure and sometimes by the age of the property. Quote your customer inclusive if that is the local convention, but do your margin arithmetic exclusive, otherwise the tax looks like profit.
Why is the band so wide?
Because system size in kilowatt-peak, whether a battery is included, and roof complexity genuinely swings the price that much. A narrow average would be more comforting and less true. The useful move is to establish where your own typical job sits inside the band, then price your marketing against that point rather than against the midpoint.
What gross margin should I expect on solar panel work?
18 to 28 percent of contract value is the working band, which is EUR 1,350 to EUR 2,100 on the EUR 7,550 midpoint job. Below 18 percent you are either buying materials badly or quoting labour at a rate that does not cover a wet week.
Does a higher job value make lead buying easier?
Usually, yes, because the lead price is close to fixed while the margin scales with the contract. At the EUR 7,550 midpoint, acquisition is 11.5 to 49.6 percent of gross margin. Raise the average job by a fifth and that percentage falls by roughly the same proportion without a single change to what you pay per lead.
