Solar Water Heaters in Morocco: 2026 Prices, Sizing and Practical Advice
A solar water heater in Morocco costs roughly 4,000 to 20,000 MAD depending on size and technology, plus 1,500 to 3,500 MAD for installation. This guide explains what to buy, what it saves and what to check on a Moroccan roof.

A solar water heater uses roof-mounted collectors to heat your domestic hot water, storing it in an insulated tank for evening and morning use. In Morocco in 2026, an entry-level unit of 150 to 300 litres costs roughly 4,000 to 12,000 MAD (equipment only), while an established brand with flat-plate collectors costs 9,500 to 20,000 MAD. Installation, mounting frame and plumbing usually add 1,500 to 3,500 MAD. With Morocco's strong sunshine, a well-sized system covers most of a household's hot water needs and cuts the electricity bill or butane use.

Indicative Moroccan market prices, recorded in November 2026; they vary with brand, capacity, quantity and installation.
These ranges combine 2026 prices listed by several Moroccan distributors and specialist retailers. The main price drivers are:
- collector type (flat plate or evacuated tubes);
- tank quality (enamelled or stainless steel, insulation, anode, warranty);
- pressure rating: low-pressure units must be fed from a rooftop tank, while pressurised units connect directly to the mains;
- electric backup element, included or not;
- installation: roof access, pipe runs to the bathrooms, waterproofing work, and travel outside the city.

How a solar water heater works
The system has three parts: the collectors, the storage tank and a backup (usually an electric element, or a solar-compatible gas heater fed with pre-heated water). This is solar thermal technology, which produces heat, not electricity. Photovoltaic panels, which produce electricity, are covered in our solar panel price guide.
Thermosiphon vs pumped (forced circulation)
- Thermosiphon: heated water rises naturally into a tank mounted just above the collectors. There is no pump and no controller. It is the cheapest and most common option on Moroccan flat roofs.
- Pumped (forced circulation): a small pump and a controller move fluid to a tank that can sit indoors. It suits large villas, guesthouses (riads) and homes where a visible rooftop tank is unwanted, but it costs more and needs more maintenance.
Flat-plate collectors vs evacuated tubes
| Flat-plate collectors | Evacuated tubes | |
|---|---|---|
| Cold-weather output | Good | Better in cold weather and early morning |
| Durability | Very robust | Broken tubes can be replaced one by one, but tubes are vulnerable to impact and hail |
| Limescale | No scale in the collector when closed loop | Water-in-tube designs scale up quickly in hard water |
| Summer overheating | Moderate | More frequent, so a thermostatic mixer is essential |
| Price | Higher | Usually cheaper at entry level |
Open loop or closed loop? In an open (direct) loop, tap water flows through the collectors. This is cheaper, but it is vulnerable to limescale and frost. A closed (indirect) loop circulates antifreeze through a heat exchanger. It is the better choice in hard-water and mountain areas. Many cheap tube heaters are also non-pressurised: never connect them directly to mains pressure.
Choosing the right size
| Household | Recommended tank | Collector area (approx.) |
|---|---|---|
| 1 to 2 people | 100 to 150 L | 1 flat plate (about 2 m²) or 12 to 15 tubes |
| 3 to 4 people | 200 L | 2 to 3 m² or 20 to 24 tubes |
| 5 to 6 people | 300 L | 2 plates (about 4 m²) or about 30 tubes |
| 7+ people or a guesthouse | 400 to 500 L or several tanks | Case-by-case design, often pumped |
Savings against butane and electricity
The 12 kg butane cylinder has sold for 50 MAD since May 2024. Further planned increases were dropped in late 2025, but the state now subsidises the cylinder heavily. According to the compensation report attached to the 2027 draft finance bill, the subsidy averaged around 62 MAD per cylinder in the first eight months of 2026. The retail price is a political decision and could change.
Hypothetical example for a family of four (160 L of hot water a day, about 170 kWh of heat a month, electricity at an average of 1.1 to 1.2 MAD/kWh):
| Option | Purchase (approx.) | Yearly hot-water cost |
|---|---|---|
| Electric water heater | 1,400 to 4,500 MAD | about 2,500 to 2,700 MAD |
| Butane gas heater | 1,800 to 4,500 MAD | about 900 MAD at today's subsidised price |
| 200 L solar + electric backup | 7,500 to 19,500 MAD installed | about 600 to 700 MAD (if solar covers 75% of needs) |
Compared with an electric heater, a well-installed entry-level system typically pays for itself in about 4 to 6 years. Compared with subsidised butane, the financial payback is slower. The main gains are then comfort, protection against future price rises and safety: Morocco's poison control centre reports carbon monoxide poisonings every winter, and gas water heaters in poorly ventilated bathrooms are a leading cause.
Is there a subsidy?
PROMASOL (launched in 2002) helped structure the market, and the Shemsi programme was announced in the early 2010s. As of November 2026, however, we found no official confirmation of an active subsidy for households. If a seller promises state aid, ask for the official reference and check with Morocco's energy efficiency agency, the AMEE.
Installation on a Moroccan roof terrace
- Face the collectors due south, clear of shade from parapets, water tanks and neighbouring buildings.
- Tilt them at about 40 to 45° to favour winter output.
- A full 300 L system weighs close to half a tonne, so have older roof slabs checked.
- Protect the waterproofing. On the coast (Agadir, Essaouira, Casablanca), use galvanised or aluminium frames and stainless fixings against wind and salt air.
- Insulate all pipes with UV-resistant lagging, and fit a safety valve, a pressure reducer if needed and a thermostatic mixing valve, because stored water can exceed 70 °C in summer.

Winter performance by city
Morocco gets about 3,000 hours of sunshine a year. You can check monthly solar data for your address with the free PVGIS tool.
- Marrakech: very sunny winters with cold nights, so insulate the tank and pipes well. See our services in Marrakech.
- Casablanca: mild but cloudier and more humid in winter, with salty air. Plan a reliable backup and corrosion-resistant fittings.
- Agadir: excellent year-round sun and mild winters, which gives some of the best payback in the country. See our services in Agadir.
- Mountains (Ifrane, Azrou, Midelt, High Atlas): frequent frost. Use a closed loop with antifreeze or heat-pipe tubes, insulate exposed pipes and drain the system if the house is left empty.
Maintenance and limescale
Water can be hard depending on the city, and especially when it comes from a well. Fit an anti-scale filter, keep the backup thermostat at 55 to 60 °C, check the anode every 1 to 2 years, and clean the glass after dust storms. Check the antifreeze every 2 to 3 years in closed-loop systems.
Brands available in Morocco
Moroccan retailers sell Bosch, Chaffoteaux, Batitherm (a Moroccan distributor since 1999 with offices in Casablanca and Rabat), Vaillant and Solarheat, alongside many unbranded imported tube systems. Prioritise local after-sales service and spare parts availability.
Mistakes to avoid
- Connecting a non-pressurised unit to mains pressure.
- Choosing an open loop in hard water or frost-prone areas.
- Poor orientation or shading.
- Skipping the thermostatic mixer.
- Believing subsidy promises without an official reference.
- Having no backup for winter.

Frequently asked questions
How much does a solar water heater cost in Morocco?
In 2026, expect about 4,000 to 12,000 MAD for an entry-level evacuated-tube unit of 150 to 300 litres (equipment only) and 9,500 to 20,000 MAD for an established brand with flat-plate collectors. Installation usually adds 1,500 to 3,500 MAD. These are indicative market prices recorded in November 2026.
What size solar water heater do I need?
Allow about 40 to 50 litres of hot water per person per day. A 200-litre tank suits most households of 3 to 4 people, and a 300-litre tank suits 5 to 6 people or homes with a bathtub.
Is there a government subsidy for solar water heaters in Morocco?
As of November 2026, we found no official source confirming an active national subsidy for households. Earlier programmes such as PROMASOL and Shemsi are not grants you can apply for today, so base your budget on the full price.
Does a solar water heater work in winter in Morocco?
Yes. On sunny winter days the collectors still heat water well, especially in Marrakech and Agadir. On cloudy days an electric element or gas heater tops up the temperature. In mountain areas, use a closed-loop system with antifreeze.
Can I install a solar water heater in an apartment?
Usually yes, if you have access to the shared roof terrace and the agreement of the building's co-owners (syndic). You also need well-insulated pipes down to the apartment.
How long does a solar water heater last?
Good-quality equipment that is properly installed and maintained often lasts 15 years or more. Check the anode regularly, descale in hard-water areas and inspect the antifreeze fluid in closed-loop systems.
