What is the solar buyback rate in Saudi Arabia?

Saudi Arabia's net metering program pays approximately 7 halala (SAR 0.07/kWh) for exported solar electricity — about 39% of the residential retail rate of 18 halala/kWh. This makes self-consumption the dominant financial strategy. Size your system to match your consumption and maximize self-consumption rather than export.

How much does solar cost in Saudi Arabia?

Residential solar in Saudi Arabia costs approximately SAR 4,000–6,000 per kWp installed in 2026. A 10kWp system costs SAR 40,000–60,000. Saudi Arabia has no VAT exemption for solar, but the government's NREP program and Vision 2030 initiatives support solar adoption. Installation quality is critical — use certified installers registered with SEC.

Why is Saudi Arabia ideal for solar despite low electricity prices?

Saudi Arabia's 6.0+ PSH daily irradiance means a 10kWp system produces 17,000+ kWh/year — nearly twice the output of the same system in Germany. The solar-AC demand match is near-perfect: panels produce maximum power during peak cooling hours (10am–4pm). As energy subsidies reform under Vision 2030, solar payback periods will shorten significantly.

Vision 2030 Solar Target: Saudi Arabia aims for 50% renewable energy by 2030. Residential solar installations qualify under the National Renewable Energy Program (NREP). Self-consumption strongly preferred — grid export at 7 halala/kWh is significantly below retail rate of 18 halala/kWh.

How to Use This Calculator

Enter your monthly bill and city

Enter your average monthly SEC (Saudi Electricity Company) bill in Saudi Riyals (SAR). The calculator uses the residential rate of SAR 0.18/kWh to estimate your consumption. Select your city — Tabuk (6.5 PSH) and Medina (6.2 PSH) are among the world's best solar locations. All Saudi cities receive exceptional solar radiation, with even the lowest (Dammam at 5.5 PSH) producing 40–50% more solar energy per panel than Germany.

Set roof area and AC share

Enter your available flat roof area in m². Saudi Arabia's flat rooftops are ideal for solar installations — no steep pitch adjustment needed. The AC share of your bill is critical: air conditioning typically accounts for 30–70% of Saudi electricity consumption and runs during peak sun hours (10am–4pm), creating a perfect match with solar production. Enter your typical AC percentage to see how much of your cooling costs solar can offset.

Self-consumption vs grid export

Grid export earns only 7 halala (SAR 0.07/kWh) — less than half the residential retail rate of 18 halala. Self-consumption is strongly preferred. Enable self-consumption priority to maximize the value of each solar kWh by displacing expensive purchased electricity rather than exporting at the low buyback rate.

The Formula

Monthly kWh = Monthly Bill ÷ SAR 0.18/kWh (residential rate) Daily kWh = Monthly kWh ÷ 30 System kWp = Daily kWh ÷ (PSH × 0.78 efficiency) Annual production = kWp × PSH × 365 × 0.78 AC offset value = Annual kWh × AC% × SAR 0.18/kWh Self-consumption savings = Annual kWh × 90% × SAR 0.18/kWh Grid export income = Annual kWh × 10% × SAR 0.07/kWh Payback = System cost ÷ Annual benefit

Saudi Arabia's desert climate produces 1,700–2,200 kWh per kWp per year — one of the world's highest yields. System efficiency of 78% accounts for inverter losses and temperature derating. Note that Saudi Arabia's high ambient temperatures reduce panel output (negative temperature coefficient ~0.35%/°C), but this is more than offset by the exceptional irradiance. Systems must use high-temperature rated components and benefit from occasional rainfall cleaning. Dust soiling in desert areas can reduce output by 5–15% if not cleaned regularly.

Example

Abdullah pays SAR 600/month to SEC for his Riyadh villa. AC accounts for 50% of his bill. He installs a 10kWp system prioritizing self-consumption.

Saudi Arabia's heavily subsidized electricity rates (SAR 0.18/kWh) create longer payback periods than markets with higher electricity prices. However, as Vision 2030 progresses and electricity subsidies are reformed, solar economics will improve significantly. The massive solar resource (6.0+ PSH in Riyadh) means systems produce far more energy per panel than anywhere in Europe.

FAQ

Is solar worth it in Saudi Arabia? ▼

Saudi Arabia has extraordinary solar resources — Tabuk and NEOM receive 6.3–6.5 PSH daily, among the world's best. The challenge is the heavily subsidized residential electricity rate of SAR 0.18/kWh, which creates 15–25 year payback periods for residential solar. However, as Vision 2030 reforms reduce energy subsidies over time, solar economics will improve dramatically. Commercial consumers with higher rates see 8–12 year paybacks. Self-consumption is essential — the 7 halala/kWh grid buyback makes export financially unattractive.

What is the grid buyback rate for solar in Saudi Arabia? ▼

Saudi Arabia's net metering program (managed by SEC under ECRA regulations) pays approximately 7 halala (SAR 0.07/kWh) for exported solar electricity — about 39% of the residential retail rate of 18 halala/kWh. This asymmetry makes self-consumption the dominant financial strategy. System sizes should be matched to actual consumption to avoid excessive export. Battery storage can help store midday surplus for evening use, improving self-consumption rates.

How does Saudi Arabia's Vision 2030 affect solar? ▼

Vision 2030 targets 50% renewable energy by 2030 (from near zero in 2016). The National Renewable Energy Program (NREP) has enabled massive utility-scale solar projects. For residential solar, ECRA (Electricity and Co-Generation Regulatory Authority) has established net metering rules allowing homes up to 2MW to connect to the grid. As fossil fuel export value increases and domestic electricity subsidies are gradually reformed, the financial case for residential solar in Saudi Arabia strengthens significantly.

Why does AC make solar ideal in Saudi Arabia? ▼

Air conditioning runs hardest from 10am to 6pm — precisely when solar panels produce peak electricity. This creates near-perfect demand matching: solar generates maximum power exactly when AC consumes maximum power. A 10kWp system producing 60kWh on a hot Riyadh day aligns almost perfectly with a large villa's AC load. This "temporal matching" means self-consumption rates of 80–95% are achievable without any battery storage — far better than European climates where demand peaks in the evening after solar production ends.

Does dust affect solar panels in Saudi Arabia? ▼

Yes — dust and sand soiling is one of the biggest operational challenges for solar in Saudi Arabia. Studies show 5–15% output reduction per month without cleaning in desert areas, with sandstorm events causing 30–50% temporary reductions. Regular cleaning (every 2–4 weeks) is essential for maximum output. Self-cleaning hydrophobic panel coatings reduce (but don't eliminate) maintenance requirements. Desert dust in Saudi Arabia is particularly fine and adheres strongly to panel surfaces. Factor in cleaning costs (~SAR 200–400/cleaning for residential systems) when calculating long-term economics.
