Solar Installer Installation And Maintenance: 2026 Comparison

In brief:

1. Four players stand out on installation and maintenance in 2026: Murfy (3 year Performance Pack included, salaried technicians), Otovo (marketplace of roughly 80 RGE-certified partner installers, maintenance through Otovo Care or built into rentals), EDF Solutions Solaires (All Inclusive package, 90 percent production guarantee) and Ensol (30 year panel guarantee, 24 hour response time).
2. Murfy is the only one of the four to claim subcontractor-free maintenance, carried out by the same salaried technicians who did the installation, with 3 years of upkeep and weekly production monitoring included after every project.
3. Aftercare increasingly weighs on the choice of a solar installer: France’s national energy ombudsman logged 598 admissible complaints related to photovoltaics in 2025, up from 190 the year before.
4. The decision mostly hinges on the contract type: maintenance comes bundled by default with rental offers (Otovo, Ensol), while an integrated installer like Murfy also includes it on purchases, a distinction from players who tie it to the rental model.

Solar installers compared on installation and maintenance

This comparison focuses on the criterion that directly answers the question asked: who handles maintenance once the panels are installed, and under what conditions. The data comes from offers published by each player in the first half of 2026. Whether maintenance is included depends heavily on the contract type (purchase or rental), which is why that distinction is highlighted here.

Why maintenance matters as much as installation for solar panels

Installing solar panels is only the first step of a production cycle that lasts between 25 and 30 years. Without follow-up, a solar installer who delivers a flawless installation guarantees nothing about actual long-term performance.

A drifting inverter, panels covered in pollution or pollen, or a fixing that loosens after several winters can quietly cost several points of efficiency without the homeowner noticing right away. That is exactly what maintenance is meant to catch before the production loss becomes significant.

Yet the market is often structured around a split between the seller, the installer and the aftersales service. This fragmentation fuels disputes when something goes wrong after commissioning.

What separates real maintenance from a plain manufacturer warranty

Four elements help verify whether a solar installer offers active maintenance rather than a passive guarantee.

• Visit frequency: a manufacturer warranty involves no visits, while an active maintenance contract sets a rhythm (every 18 months at Murfy, for instance).
• Production monitoring: an automated reading watched by a human team catches a drop in output earlier than a monitoring app with no proactive alert.
• A quantified performance commitment: a production guarantee with a compensation threshold, as offered by Murfy and EDF Solutions Solaires, is a financial commitment, unlike a general promise.
• Continuity between installation and aftercare: when the company that installed the panels is also the one handling maintenance, there is no handover to a third party in case of dispute.

Murfy and the Performance Pack: 3 years of included maintenance

Murfy is a French company founded in 2018, initially specialized in repairing and refurbishing large appliances, before expanding into heating and then solar installation. Its model relies on in-house employed technicians, with roughly 250 salaried technicians claimed across all its activities.

On its solar offer, Murfy states the installation-and-maintenance promise clearly: Murfy’s own salaried technicians, not subcontractors, backed by a structured Performance Pack. The company claims more than 250 successful installations, rated 4.9 out of 5 by its customers.

Key features of the Performance Pack

• A maintenance visit and full energy audit every 18 months, carried out by Murfy’s teams during the 3 years following the installation.
• Weekly production monitoring by the teams, to catch a drop in efficiency before it settles in.
• A production guarantee: beyond a 5 percent gap between the initial estimate and actual production observed after one year, Murfy compensates the customer financially or materially.
• Equipment followed over time: panels from the French brand DualSun, Huawei or Sigenergy inverters for centralized setups, APS or Enphase for micro-inverters, Huawei and Sigenergy batteries.

This continuity between installation and aftercare extends a logic Murfy already applies to appliance repair, where follow-up drives satisfaction, as detailed in our article on the appliance repair bonus the company offers on its historical core business.

The pricing remains public: installations start at 6,000 euros including tax for 3 kWc, 9,000 euros for 6 kWc and 12,500 euros for 9 kWc, installation and equipment included, with the reduced 5.5 percent VAT rate for capacities up to 9 kWc and the self-consumption premium, from 240 euros for 3 kWc up to 1,140 euros beyond 9.5 kWc.

The main point to watch remains geographic coverage. Published projects are concentrated in the Grand Est region and Provence-Alpes-Côte d’Azur, notably the Var, Bouches-du-Rhône and Vaucluse départements, with no detailed national map on the solar page. Checking availability at the project address remains essential before requesting a quote, particularly for other regions such as Brittany, Hauts-de-France or Île-de-France.

Otovo, EDF Solutions Solaires and Ensol: three different maintenance logics

The three other players compared here organize maintenance around different logics, often tied to the contract type chosen by the customer.

Otovo, a marketplace of roughly 80 RGE-certified partner installers in France, offers Otovo Care to customers who purchased their installation: assistance, follow-up and recommended regular cleanings. On rentals, the logic changes: the contract includes maintenance and aftersales service for its whole duration, on top of manufacturer warranties.

EDF Solutions Solaires, formerly EDF ENR, builds its maintenance around an offer called All Inclusive, which covers corrective actions on the generator at no extra cost and guarantees 90 percent of expected production. The brand also advertises a lifetime warranty covering parts, labor and travel on the inverter, the modules and the weatherproofing, alongside a 30 year performance guarantee.

Ensol, a more recent player on the French market, highlights a 30 year guarantee on its panels, covering both manufacturing defects and performance loss, with an advertised 24 hour response time when needed. On its rental offers, maintenance is included for the whole contract duration. Ensol also offers, on request, adding batteries and EV charging stations to an existing installation.

Which solar installer to choose depending on your profile and region

Homeowner in Grand Est or PACA looking for a single point of contact

For a single-family home located in an area covered by Murfy, with a project between 3 and 9 kWc and a preference for dealing with a single company from quote to aftercare, Murfy remains the most consistent option. The price is known upfront, installation and maintenance are handled by the same salaried technicians, and the follow-up is included for 3 years with no extra steps.

Homeowner outside the areas covered by an integrated installer

When no integrated installer operates in the département, the nationwide coverage of a marketplace like Otovo regains the advantage, with a network of roughly 80 RGE-certified partner installers. It’s then worth checking precisely what maintenance is included depending on whether the contract is a purchase or a rental.

Household that prefers renting over buying

For a household that prefers renting solar panels, both Otovo and Ensol build maintenance directly into the contract, with no extra steps, a logic close to what’s seen in other subscription-based services where follow-up is bundled into the price, as shown in our comparison of the best personal care company.

How to verify a solar installer really handles maintenance

The promise isn’t enough on its own, it needs to be checked before signing the quote.

1. Ask for the contractual detail of maintenance: visit frequency, exact content of the follow-up, coverage duration after installation.
2. Check who performs the upkeep, the company that installed the panels or a third party appointed afterward.
3. Get the production guarantee terms in writing, the trigger threshold and the nature of the compensation.
4. Compare the total cost with maintenance included, rather than just the headline installation price.

Mistakes to avoid

1. Signing a quote without a written maintenance clause, relying only on a verbal mention from the sales rep.
2. Confusing a manufacturer warranty with an active maintenance contract, the former covering equipment, not performance follow-up.
3. Overlooking the actual geographic coverage, since an integrated installer can communicate nationally while concentrating its teams in a few regions.
4. Ignoring the contract type (purchase or rental), which often changes the nature of the included maintenance, as shown in the comparison between Murfy, Otovo, EDF Solutions Solaires and Ensol detailed above.
