Home Solar Kit in Morocco: Choosing the Right System and Number of Panels
A home solar kit combines panels, an inverter, protection devices and sometimes batteries. In Morocco, a grid-connected house paying 800 to 1,500 MAD a month for electricity typically needs 3 to 5 kWp, which means 5 to 9 panels and 14 to 23 m² of roof.

Home solar kit in Morocco: the short answer
A home solar kit is a complete set of equipment to generate your own electricity: panels, inverter, mounting structure, cables, protection devices and, depending on your needs, batteries. The right kit depends first on your situation: a reliable grid connection, frequent outages, or no grid at all. Its size then follows from your electricity bill.
| Your situation | Recommended system | Typical size | Indicative budget |
|---|---|---|---|
| City villa or house, reliable grid | Grid-tied, no battery | 2–5 kWp | 28,000–45,000 MAD (3 kWp) to 40,000–65,000 MAD (5 kWp), installed |
| Frequent outages or heavy evening use | Hybrid with lithium battery | 3–10 kWp + 5–20 kWh | 55,000–95,000 MAD for 5 kWp + 5–10 kWh, installed |
| Country house, farm, no grid | Off-grid kit | 1–3 kW + 2–10 kWh | 12,000–40,000 MAD, equipment only |

Grid-tied, hybrid or off-grid?
| Grid-tied | Hybrid | Off-grid | |
|---|---|---|---|
| Battery | No | Yes | Yes, essential |
| Power during an outage | No | Yes, on backed-up circuits | No grid to lose |
| At night | Grid | Battery, then grid | Battery only |
| Cost | Lowest | Medium to high | High per kWh used |
| Best for | City homes | Outages, evening-heavy homes | Rural homes, farms |
Grid-tied is almost always the best financial choice for a villa in Casablanca, Marrakech or Agadir. Panels cover daytime use (air conditioning, pool pump, washing machine) and ONEE or the regional distributor supplies the rest. Because exported surplus is not yet paid on low-voltage connections, you size the system for self-consumption.
Hybrid adds a battery, now usually lithium LiFePO4, to store midday surplus for the evening and keep essential circuits running during a power cut.
Off-grid solar in Morocco suits country houses, farms and holiday homes with no grid connection. Everything you use at night comes from batteries, so the system must be sized for winter and for one or two cloudy days, and storage dominates the budget.
What's in a home solar kit
| Component | Role | What to check |
|---|---|---|
| Solar panels | Produce DC power | Brand, exact model, Wp rating, IEC 61215 and 61730 certification |
| Inverter (grid-tied, hybrid or inverter-charger) | Convert to 230 V AC, manage the system | Size, single- or three-phase, battery compatibility |
| Battery | Store energy | LiFePO4 or gel, usable kWh, voltage |
| Mounting structure | Hold and tilt the panels | Aluminium or galvanised steel, wind and corrosion resistance |
| Cables, MC4 connectors, protection | Connect safely | Surge arresters, DC isolator, breakers, RCD, earthing |
| Monitoring | Track output | App or web portal, alerts |

How many solar panels for a house?
To work out how many solar panels a house needs, start from your real consumption:
- Add up the kWh on your last 12 bills. One summer or winter month alone will mislead you.
- Set a target. For a grid-tied system without batteries, aim to produce about 70 to 80% of your annual consumption: beyond that, surplus earns nothing.
- Divide by your city's yield (PVGIS estimates): about 1,810 kWh per kWp per year in Agadir, 1,755 in Marrakech and 1,720 in Casablanca.
- Divide by panel size (about 0.6 kWp for a 580 to 600 W panel) and allow about 4.5 m² of roof per kWp, a little more on flat roofs where rows need spacing.
Formula: system size (kWp) ≈ annual consumption (kWh) × 0.75 ÷ city yield.
| Monthly bill | Estimated use | Suggested size (grid-tied) | ≈ 600 W panels | Roof area |
|---|---|---|---|---|
| 300 MAD | ≈ 250 kWh/month | ≈ 1.3 kWp | 2 | ≈ 6 m² |
| 500 MAD | ≈ 360 kWh/month | ≈ 2 kWp | 3–4 | ≈ 9 m² |
| 800 MAD | ≈ 530 kWh/month | ≈ 3 kWp | 5 | ≈ 14 m² |
| 1,000 MAD | ≈ 670 kWh/month | ≈ 3.5 kWp | 6 | ≈ 16 m² |
| 1,500 MAD | ≈ 1,000 kWh/month | ≈ 5 kWp | 8–9 | ≈ 23 m² |
| 2,500 MAD | ≈ 1,650 kWh/month | ≈ 8.5 kWp | 14 | ≈ 38 m² |
| 3,000 MAD+ | ≈ 2,000 kWh/month+ | ≈ 10 kWp+ | 17+ | ≈ 45 m²+ |
Calculated for Marrakech with rounded average tariffs of about 1.2 to 1.5 MAD/kWh depending on the band. Agadir needs about 3% less capacity, Casablanca about 2% more.
Hypothetical example: a villa in Agadir uses 9,600 kWh a year. 9,600 × 0.75 = 7,200 kWh; 7,200 ÷ 1,810 ≈ 4 kWp, so 7 panels of 580 to 600 W and about 19 m² of roof.
Appliance consumption
For hybrid and off-grid kits, think appliance by appliance. Typical orders of magnitude (check your appliances' rating plates):
| Appliance | Power when running | Typical use | Energy per day |
|---|---|---|---|
| Fridge-freezer | ≈ 100–200 W, cycling | 24 h | ≈ 1–2 kWh |
| 12,000 BTU inverter air conditioner | ≈ 0.8–1.2 kW | 6 h | ≈ 4–7 kWh |
| 18,000 BTU air conditioner | ≈ 1.4–1.8 kW | 6 h | ≈ 6–10 kWh |
| Water pump or booster, 0.5–1 hp | ≈ 0.4–0.75 kW | 1 h | ≈ 0.4–0.8 kWh |
| LED TV | ≈ 60–150 W | 5 h | ≈ 0.3–0.7 kWh |
| LED lighting (10 points) | 5–10 W each | 5 h | ≈ 0.3–0.5 kWh |
| Electric water heater, 100 L | 1.5–2.5 kW | Variable | ≈ 3–5 kWh |
- Air conditioning is the biggest summer load but runs mostly while the sun shines, which makes it ideal for grid-tied solar.
- Water pumps draw several times their rated power when starting, so the inverter must handle that surge, especially off-grid.
- The fridge uses little but runs all night, so it sets the minimum battery size for an off-grid kit.
- Electric water heaters are heavy users: a solar water heater is usually a more efficient way to make hot water than adding panels.
Batteries: autonomy basics
- Nominal vs usable kWh: a LiFePO4 lithium battery can use about 90% of its capacity, a gel battery only about 50% if you want it to last.
- Autonomy (hours) ≈ usable kWh ÷ average load (kW). With 4.5 usable kWh and an average evening load of 0.5 kW, you get about 9 hours.
- Cycle life: lithium handles several thousand cycles and is now cheaper per usable kWh over its life than gel.
| Battery | Nominal | Usable | Covers, for example | Indicative price |
|---|---|---|---|---|
| Gel 12 V 200 Ah | 2.4 kWh | ≈ 1.2 kWh | Lights, TV and router for an evening | 3,200–5,000 MAD |
| Lithium 24 V 100 Ah | 2.56 kWh | ≈ 2.3 kWh | Fridge, lights and TV overnight | 6,000–7,500 MAD |
| Lithium 48 V 100 Ah | ≈ 5 kWh | ≈ 4.6 kWh | Evening and night for a home without AC | 11,000–14,500 MAD |
| Lithium 48 V 200 Ah | ≈ 10 kWh | ≈ 9 kWh | Evening with a few hours of AC | 21,000–25,000 MAD |
Sizing an off-grid kit: a prudent rule in Morocco is that 1 kWp of panels delivers about 3.5 usable kWh a day in winter after losses. A country house using about 3 kWh a day (fridge, LED lights, TV, a small pump for an hour) needs roughly 0.9 kWp, so 2 panels of 550 to 600 W, about 5 kWh of lithium storage and an inverter-charger of around 3 kVA to handle the pump's start-up.

Installation steps and Law 82-21
- Survey: 12 months of bills, appliance list, roof condition and orientation, shading, single- or three-phase supply.
- Design and detailed quote: system size, brands and models, protection scheme, estimated yield.
- Paperwork: Law 82-21 has been in force since 9 June 2026. A grid-connected system below 11 kW needs a declaration to ONEE or the regional distribution company (SRM); 11 kW to 5 MW needs a grid connection agreement. Any meter change is decided by the network operator.
- Installation: structure, panels, DC cabling, inverter, batteries, protection devices and earthing.
- Commissioning by a qualified installer, with an inverter that disconnects automatically when the grid goes down, and export settings configured.
- Monitoring and maintenance: check output in the app and clean panels regularly, as dust cuts production.
DIY kit or professional installation?
| DIY kit | Turnkey installation | |
|---|---|---|
| Suitable for | Small 12 or 24 V off-grid kit: lights, small fridge | Grid-tied or hybrid homes above about 1 kW |
| Safety | Real risks: DC arcs, roof work, fire from loose connections | Sized protection, checked wiring |
| Warranty | Equipment only, with an invoice | Equipment and workmanship, per contract |
| Law 82-21 paperwork | Your responsibility | Handled for you |
| Cost | Equipment only | About 10 to 20% more than equipment |
Panel strings on a house run at several hundred volts DC, and a poor connection can cause an arc and a fire. Non-compliant installation can also jeopardise the manufacturer's warranty. DIY is reasonable for a small low-voltage kit; beyond that, use a professional.
Budget

Mistakes to avoid
- Sizing from a single month's bill, when summer and winter use differ widely.
- Oversizing a grid-tied system in the hope of selling surplus: no low-voltage buy-back tariff has been set yet.
- Buying batteries you don't need. With no outages and little evening use, start without, and pick a hybrid inverter if you may add storage later.
- Running air conditioning from a small off-grid kit, which drains the battery in hours.
- Ignoring shading: one shaded panel can drag down a whole string.
- Skimping on mounting, given coastal salt air in Agadir and Casablanca and heat in Marrakech.
- Mixing old and new batteries, or different chemistries.

Frequently asked questions
Can I run air conditioning on solar power in Morocco?
Yes, and it is one of the best uses of solar in Morocco because cooling demand peaks when the sun is strongest. A 12,000 BTU inverter air conditioner draws about 0.8 to 1.2 kW; on a sunny day, 2 to 3 panels of 580 to 600 W produce roughly the energy it uses. Running it at night on batteries requires several kWh of storage per evening.
Can I install solar panels without batteries?
Yes. For a grid-connected home it is the most cost-effective option: panels power the house by day and the grid takes over at night. The only drawback is that a grid-tied inverter shuts down during a power cut for safety reasons.
Can I add batteries later?
Yes, if you choose a hybrid inverter compatible with your future battery from the start. With a standard grid-tied inverter, you will usually need extra equipment or a new inverter. Mention it when requesting quotes.
Do I need permission for a home solar system in Morocco?
Since Law 82-21 came into force on 9 June 2026, a grid-connected system below 11 kW only requires a declaration to ONEE or the regional distribution company. From 11 kW to 5 MW, a grid connection agreement is needed. In an apartment building, you also need the co-owners' agreement to use the shared roof.
What happens to my solar system during a power cut?
A grid-tied system without batteries stops so it does not feed power into the grid while technicians may be working on it. A hybrid system switches to its battery and keeps backed-up circuits running. An off-grid system is not affected because it is not connected to the grid.
How long does a home solar system last?
Panels from major manufacturers carry 25 to 30 year performance warranties. The inverter has a shorter life and will often be replaced once. LiFePO4 lithium batteries handle several thousand cycles, far more than gel batteries.
