Frequently asked questions
How much does a solar panel produce in Dakhla?
A well-oriented 500 Wp panel produces about 951 kWh a year in Dakhla, or 1,901 kWh per installed kWp (PVGIS, roof tilted 30° due south). Output ranges from 151 kWh per kWp in the weakest month to 178 kWh in the strongest.
How much does a home solar system cost in Dakhla?
For a home with a 500 MAD monthly bill, you need about 2 kWp, or 4 panels, for a budget of around 22,000 MAD at 11 MAD per watt-peak. The actual price depends on the installer, the equipment and the roof.
Is solar worth it in Dakhla?
For most households, yes: with a 500 MAD monthly bill, the system pays for itself in 8.1 years and returns about 60,903 MAD net over 25 years. The higher the bill, the faster the payback, because solar replaces the most expensive tranches of the ONEE tariff first.
Can you sell surplus solar power to the grid in Dakhla?
Morocco's self-generation law 82-21 allows surplus power to be fed into the grid, capped at 20% of yearly output. The residential buy-back tariff has not been published yet, so the figures on this page leave it out: they are conservative estimates.
Method and sources
- Output: PVGIS v5.2 (European Commission Joint Research Centre), at the city centre, rooftop panels tilted 30° due south, 14% system losses.
- Savings: ONEE low-voltage residential tariff by tranche (tax included). Solar replaces the most expensive kWh of the bill first. The share used on site depends on system size; no surplus sales.
- Sizing: a system covering about 80% of yearly consumption, rounded to half a kWp, with 500 Wp panels.
- Cost: 11 MAD per installed watt-peak (an assumption: use your installer's quote). Maintenance 1% a year, 0.5% yearly output loss, 2% yearly tariff rise, 25-year life.
