Low grid reliability increases solar value: With only 50% EDM uptime, a solar + battery system covers outages and increases self-consumption. Consider adding 10–20 kWh battery storage to maximize value.

How to Use This Calculator

Enter your monthly bill and province

Enter your average monthly electricity bill in Mozambican meticals (MT/MZN) from EDM (Electricidade de Moçambique), the state electricity utility. EDM uses a tiered residential tariff of MZN 4–9/kWh (~$0.06–0.14/kWh). Select your province — Tete (6.0 PSH) in northern Mozambique is among Africa's sunniest regions, with an inland continental climate and minimal cloud cover. All Mozambican provinces have outstanding solar resources, substantially better than southern Europe.

Set EDM grid hours and genset mode

Mozambique's grid reliability is a critical variable. EDM supplies 24-hour power in central Maputo, but provincial towns typically receive 8–18 hours/day, and rural areas often have no grid access. Enter your actual grid hours to model the true value of solar + battery backup. If you operate a diesel generator as primary or backup power, enable the genset replacement mode — diesel in Mozambique costs ~MZN 45/kWh ($0.70/kWh), approximately 7 times the EDM tariff, making genset replacement economics dramatically superior.

FUNAE and Mozambique's solar opportunity

Mozambique has approximately 70% of its 33 million population without grid access, primarily in rural areas. FUNAE (Fundo de Energia), the government energy fund, manages rural electrification programs using solar as the primary technology. The country has vast solar resources (5.5–6.0 PSH across all provinces) and rapidly declining solar equipment costs. Solar + LiFePO4 battery systems are the most economical electrification solution for the 23+ million Mozambicans without grid access. Larger urban and commercial installations benefit from solar self-consumption and backup during EDM outages.

The Formula

Monthly kWh = Monthly Bill ÷ MT 6.50/kWh (blended EDM rate) Annual production = kWp × PSH × 365 × 0.80 efficiency Grid backup mode: self-consumption = 50% + (1-grid uptime) × 30% Genset mode: self-consumption = 90% of production (replaces diesel) Annual benefit = utilized kWh × effective rate (EDM or diesel equiv.) System cost = kWp × MT 60,000–90,000/kWp (~$950–1,400/kWp) Grid payback = 7–10 years; Genset replacement = 3–5 years

Mozambique's Renewable Energy Strategy and National Electrification Strategy target 100% electrification by 2030, with solar central to achieving this goal. The Government of Mozambique, with World Bank, AfDB, and EU support, has launched the ProEnergia and PRODAP programs for rural solar electrification. FUNAE administers community solar projects. For commercial investors, Mozambique's investment framework (Law 3/93 and amendments) provides tax benefits for renewable energy projects. No formal residential net metering scheme exists under EDM as of 2026, though draft regulations have been discussed.

Example

Manuel — Maputo home, 5kWp with EDM backup

Manuel owns a home in Maputo and pays MT 2,000/month for EDM electricity. His area has 12 hours/day grid availability. He installs a 5kWp + battery system for self-consumption and outage backup.

Monthly billMT 2,000
Province / PSHMaputo, 5.5 PSH
System size5 kWp
Grid hours12 hrs/day (typical EDM)
Genset replacementNo — EDM supplement

Result

Annual production~8,030 kWh/yr
Production per kWp~1,606 kWh/kWp/yr
Annual savings~MT 41,755/yr
System cost rangeMT 300,000 – 450,000
Payback~8.9 years
25-year net savings~MT 668,875

Maputo's 5.5 PSH delivers 1,606 kWh/kWp/yr — outstanding by any standard. Despite no net metering, self-consumption savings and outage backup produce reasonable economics. For commercial buildings and hotels in Pemba or Inhambane with diesel genset dependence, the economics are even more compelling — payback often under 4 years. Note the MZN has depreciated significantly over the past decade; solar saves in MZN terms, hedging against currency depreciation of energy-cost exposure.

FAQ

Yes, particularly for genset replacement and off-grid applications. Mozambique has outstanding solar resources (5.5–6.0 PSH) across all provinces. For homes and businesses replacing diesel generators (~MZN 45/kWh), payback is typically 3–5 years. For grid-connected EDM supplement, payback is 7–10 years. The 70% rural population without grid access represents a massive off-grid solar opportunity. FUNAE-supported village solar systems are transforming rural electrification across the country.
EDM grid reliability varies significantly. Maputo central areas: 20–24 hours/day. Matola and suburban Maputo: 16–20 hours. Provincial capitals (Beira, Nampula, Quelimane): 8–16 hours on average. Smaller towns: 4–12 hours. Frequent load shedding, cyclone damage (Mozambique's coast is cyclone-prone), and infrastructure constraints mean outages are a significant reality for most Mozambican electricity users. This makes solar + battery storage particularly valuable as it provides power during EDM outages, increasing self-consumption and the effective value of solar production.
FUNAE (Fundo de Energia) is Mozambique's government energy fund that manages rural electrification programs. It has installed solar systems in thousands of rural villages, health posts, schools, and community centers across all provinces. FUNAE coordinates with international development partners (World Bank ProEnergia, AfDB, EU, USAID) to finance off-grid solar. FUNAE also manages mini-grids — small solar + battery + diesel hybrid systems that power remote communities. For rural Mozambican communities, FUNAE is the primary pathway to solar access. Contact FUNAE's regional offices in each provincial capital for program eligibility and application procedures.
Installed solar costs in Mozambique run approximately MZN 60,000–90,000/kWp (~$950–1,400/kWp). A 5kWp urban home system costs MZN 300,000–450,000 (~$4,750–7,100). The MZN has depreciated significantly, making dollar-denominated equipment relatively more expensive over time. Most solar equipment is imported through Maputo or Beira. Local installers operate mainly in Maputo, Beira, Nampula, and Pemba. The Associação Moçambicana das Energias Renováveis (AMER) represents the local solar industry. Note: no import duty exemption for solar equipment currently, though reform discussions are ongoing.
Tete province in northwestern Mozambique receives 6.0 PSH — among the highest in Africa. This is due to its inland continental climate: far from coastal humidity and cloud cover, at moderate altitude (~300–600m), and with minimal seasonal variation. The dry season (April–November) in Tete is exceptionally sunny with near-zero cloud cover. Even the wet season (December–March) maintains relatively high solar radiation compared to coastal provinces. Tete is also home to large coal deposits and the Cahora Bassa hydroelectric dam — making it strategically important for Mozambique's energy future. Large-scale solar farms are planned for Tete to complement hydropower.
