The short version: a serious installer in Morocco can be checked on five points: a registered company (RC, ICE, physical address), installations you can visit in your region, a detailed quote in kWp with exact brands, written warranties and after-sales service that still answers after you have paid. Ask for three quotes, compare the price per kWp (2026 market benchmark: 10,000 to 14,000 DH per kWp turnkey for residential) and drop any quote well below the market without a line-by-line explanation.
Solar panels last 25 to 30 years. The company that fits them, sometimes far less. The Moroccan market has grown fast: alongside solid companies you find kit resellers with no qualified electrician, firms created six months ago and quotes sent over WhatsApp without anyone ever seeing the roof. Here is the checklist we would apply ourselves to equip a relative's house.
Why the installer matters more than the panel brand
Because panels from the big brands are broadly equivalent, and almost everything else depends on the installer: sizing based on your bills, quality of the mounting, wiring, protections, inverter settings and after-sales service. A badly fitted system loses more production than an entry-level panel ever will.
Jinko, LONGi, JA Solar and Trina come out of comparable factories, with similar warranties. What varies from one job to the next is the work around them: a poorly sealed fixing damages the roof, an undersized cable heats up and wastes kWh. And in ten years, when the inverter stops, you will be calling your installer, not the factory.
What are the 10 criteria of a serious installer?
A serious installer has a verifiable legal existence, references you can visit, and comes to your home before pricing anything. The quote details brands and capacity in kWp, the warranties are in writing, the after-sales service answers. The ten criteria, in the order we would check them:
- Verifiable legal existence. Trade register, ICE, physical address. A kit seller on Avito with no premises will not be there to help you in five years.
- A real track record. A company that has been through several chergui summers and a few rainy winters has already corrected its early mistakes. On other people's roofs, not on yours.
- References you can visit. Ask for two or three installations in your region and the customers' numbers. A refusal tells you plenty.
- A technical visit before the quote. Roof, shading, electrical panel, the last twelve months of bills. A quote priced from a single photo is a quote that will need redoing.
- A quote in kWp with exact brands and models. "Guaranteed 550W panel" with no precise reference means nothing.
- Estimated annual production, with the working shown. In kWh per year, with the calculation method. That figure will determine your savings, not the peak capacity.
- Written warranties. Product, output, workmanship, with the name of whoever backs them in Morocco. More on this below.
- Professional liability insurance. People will be climbing on your roof and working in your electrical panel.
- Structured after-sales service. A stated response time, spare parts stocked in Morocco, production monitoring through the inverter's app.
- Handling of the paperwork. The declaration with the grid operator (ONEE, Lydec, Redal or Amendis depending on the city) for a grid-connected system, approved-supplier status for the pumping subsidy.
How do you compare three quotes without getting it wrong?
Bring every quote back to the price per kWp, then compare line by line: exact brands, estimated annual production, what the installation includes, warranties. Two quotes can only be compared on the same scope. A 20% gap always has an explanation somewhere, and it is better to find it before signing than after.
| Quote line | What to check | Red flag |
|---|---|---|
| Capacity | Stated in kWp, consistent with your bills | The same round number for every customer |
| Panels | Brand, model, exact reference | "German panel" or "class A" with no reference |
| Inverter | Brand, model, warranty, monitoring app | Inverter unnamed, or oversized for no reason |
| Mounting and installation | Type of fixing, waterproofing, ballast or drilling | Line missing from the quote |
| Electrical protections | DC and AC boxes, surge arrester, earthing | No detail, "wiring included" |
| Estimated production | kWh/year with the calculation method | A promised percentage saving with no figure |
| Price | Price per kWp in line with the market | A gap of more than 20% with no written justification |
The 2026 market benchmark for a residential grid-connected installation: between 10,000 and 14,000 DH per kWp turnkey, depending on the roof, the equipment and the city. Detailed ranges by system size are in our guide to solar panel prices in Morocco. These are benchmarks, not promises: only a technical visit produces a firm figure.
What are the most common traps in Morocco?
Four traps come up again and again in the installations we take over: downgraded equipment sold as new, undersized kits priced without a study, abnormally cheap quotes and installers who vanish once paid. Since 2026 a misleading sales pitch has joined the list: the promise that you can sell your electricity to the grid.
Downgraded equipment. Second-rate panels and reconditioned batteries circulate on the market, with no mention on the quote. Demand the exact model reference and compare it with the manufacturer's datasheet. A serial number can be checked.
The undersized kit. A kit seller offers a round capacity, the same for everyone. An installer sizes from your actual consumption and your ONEE brackets. The difference shows after a year, when the bill has not dropped as promised.
The price that looks too good. Take an illustrative example: 3 kWp offered at 18,000 DH turnkey when the market runs between 25,000 and 40,000 DH. Something got cut. The mounting, the protections, the qualified labour, or the company itself within two years. At that kind of gap you are not getting a bargain, you are carrying the risk yourself.
The ghost installer. A solar installation needs a minimum of follow-up: an inverter can fail, and a panel that is never cleaned loses 15 to 25% of its production in three months of dust. Our guide to panel maintenance in Morocco covers this in detail. Without reachable after-sales service, your system will age badly and nobody will notice.
The false promise of selling your power. Since June 9, 2026, law 82-21 and its implementing decree let you self-produce at home with a simple declaration below 11 kW on low voltage. Selling the surplus, capped at 20% of annual production, is for now open only to businesses connected on medium or high voltage; ANRE has not yet set the low-voltage buyback tariff. A salesman promising a household an income from selling power is selling something that does not exist yet. The detail is in our practical guide to law 82-21.
What questions should you ask before signing?
Eight questions are enough to tell a professional from a mere seller. Ask them in writing, on WhatsApp for instance: a written answer commits. A serious installer answers without taking offence. The one who dodges the warranty or after-sales question has already given you his real answer.
- Who does the technical visit, and when?
- Which exact brands and models, for the panels and for the inverter?
- What annual production in kWh, and calculated how?
- Who backs the manufacturer's warranty in Morocco, and what is the procedure if something fails?
- What after-sales response time do you commit to?
- Is the declaration with the grid operator included in the service?
- What is the payment schedule? Never 100% upfront.
- Can you give me two customers in my region I can call?
Which warranties should you demand in writing?
Three separate warranties belong on the quote or the contract: the product warranty on the equipment, the output warranty on the panels and the installer's workmanship warranty. A warranty given verbally does not exist. And a manufacturer's warranty is only worth something if an importer or distributor backs it in Morocco.
| Warranty | Typical market duration | What to check |
|---|---|---|
| Panel product | 12 to 15 years, up to 25 with some manufacturers | The exact model reference appears on the quote |
| Panel output | 25 to 30 years, around 80 to 87% of initial capacity at term | Degradation curve in the datasheet |
| Inverter | 5 to 10 years | Who handles the exchange in Morocco, and in how many days |
| Lithium batteries | Around 10 years or a number of cycles | The warranty in cycles counts for more than the years |
| Workmanship and waterproofing | 1 to 2 years minimum | Written, signed, with a response time |
The point almost nobody checks: who actually processes the warranty. If the manufacturer has no representative in Morocco and your installer has disappeared, the 12-year warranty printed in the brochure will do you no good. Ask for the name of the local distributor before you sign.
Why does the supplier's approval matter for subsidies?
Because without an approved supplier, there is no subsidy. Since February 19, 2024, the Agricultural Development Fund (FDA) has covered 30% of the cost of buying and installing a solar pumping kit. The file goes to the DPA or ORMVA for your region, under three main conditions: being a working farmer, having drip irrigation in place and buying from an approved supplier.
In practice, a farmer who fits his borehole with drip irrigation but goes through a non-approved installer pays full price. Before committing, ask for proof of approval and who puts the file together: a good installer takes care of it, that is part of the job. Our solar pumping page describes how we help, and our article on solar pumping and the FDA subsidy details how the file is assembled.
