Is solar worth it in Beni Mellal?
For most households, yes: with a 500 MAD monthly bill, the system pays for itself in 10.2 years and returns about 54,943 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 Beni Mellal?
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.
