How to Use This Calculator

Enter your bill and price zone

Enter your average monthly electricity bill in Norwegian krone (NOK) — this appears on your invoice from Tibber, Fjordkraft, Hafslund, or other supplier and should include nettleie (grid fee) and energy taxes. Select your Norwegian price zone (NO1–NO5). Zone determines both spot price and solar yield. Oslo (NO1, 2.7 PSH) and Kristiansand (NO2, 2.8 PSH) offer the best economics; Bodø and Tromsø (NO4, 1.8 PSH) face extreme latitude constraints with near-zero winter production.

System size and Enova støtte

Select your system size in kWp. The Enova støtte grant applies automatically: kr 7,500 base plus kr 1,250 per kW, up to a maximum of kr 32,500 for 20 kW systems. Since January 2024, residential solar systems up to 15 kWp are exempt from MVA (Norwegian VAT at 25%). Apply for the Enova støtte at enova.no before your installation date — applications submitted after installation are not accepted.

Plusskunde and self-consumption

When your solar system produces more than you consume, you become a Plusskunde and export surplus electricity to the grid at the spot price minus a small operator margin. In summer, spot prices can be low (sometimes near zero in NO4/NO5), making self-consumption with a battery far more valuable than export. In Norway, sizing your system to cover spring/autumn consumption — rather than maximizing peak summer production — typically gives the best economic return.

The Formula

Monthly kWh = Monthly Bill ÷ kr 1.20/kWh (incl. nettleie + avgifter) Annual production = kWp × PSH/day × 365 × 0.80 efficiency Self-consumption = Annual kWh × 35% (no battery) or 55% (with battery) Self-consumption savings = Self-consumed kWh × kr 1.20/kWh Plusskunde income = Exported kWh × kr 0.55/kWh (spot-based) Enova støtte = kr 7,500 base + kr 1,250/kW (max kr 32,500 at 20 kW) No MVA on residential systems under 15 kWp (since Jan 2024) Payback = Net cost after Enova ÷ Annual benefit

Norway's electricity price includes the spot component plus nettleie (grid fee) plus elavgift and Enova-avgift (energy taxes). The blended consumer price used here of kr 1.20/kWh is an approximate annual average — actual prices vary significantly by zone and season, and can be much higher in winter. PSH (peak sun hours) values represent annual daily averages for south-facing panels at the recommended tilt angle (30–40° for southern Norway, 20–30° for northern Norway). Winter production in NO4 is near zero from November to January.

Example

Lars — Oslo home, 8 kWp, NO1 + Enova støtte

Lars lives in Oslo and pays kr 1,800/month. He installs an 8 kWp south-facing system and applies for Enova støtte before installation.

Norway's low PSH (vs. southern Europe) and relatively low spot prices make payback periods longer than in Mediterranean countries — typically 15–25 years for well-positioned systems. The Enova støtte materially reduces upfront cost. Systems in NO2 (Kristiansand) or south-facing roofs in NO1 see the best Norwegian payback periods.

FAQ

Solar in Norway is financially viable in the south (NO1, NO2) but marginal in the far north (NO4). Norway's low historical electricity prices made solar less attractive, but rising prices and the Enova støtte grant have improved economics. Typical payback: 15–25 years for southern Norway, 25–35+ years for NO4. Key advantage: Norway's hydroelectric-dominated grid means solar reduces your import during low-hydro price spikes, which can be substantial. Many Norwegians also value energy independence.
Enova støtte for residential solar (solcellePanel) is a non-repayable grant of kr 7,500 base + kr 1,250 per installed kW, maximum kr 32,500 for a 20 kW system. Apply at enova.no before installation — post-installation applications are rejected. You need an approved installer quote. Payment arrives after installation is complete and verified. The grant is part of Enova's broader Støtte til fornybar energi program. Budget availability is not guaranteed for future years.
Plusskunde is the Norwegian status for households that produce more electricity than they consume in a given hour and export to the grid. Registration is free and automatic via your nettselskap (grid operator) when you install solar. You receive the hourly spot price minus a small margin from your nettselskap for exported kWh. Important: in summer (especially in NO4/NO5), spot prices can be near zero, making export revenue minimal. Self-consumption via a battery is typically more valuable than export.
Since January 2024, residential solar panel systems up to 15 kWp are exempt from MVA (Norwegian VAT, normally 25%). This is a significant saving — a 10 kWp system at kr 180,000 incl. MVA would be kr 144,000 excl. MVA. Ensure your installer invoices correctly without MVA. Systems over 15 kWp or commercial installations still pay 25% MVA. This exemption combined with the Enova støtte substantially reduces net installation costs.
At 67°–70°N latitude, Bodø and Tromsø experience near-zero solar production from mid-November to late January (polar night or very short days with extremely low sun angles). This reduces the annual average PSH to just 1.8, compared to 2.7–2.8 in Oslo and Kristiansand. Summer production is actually high (midnight sun), but electricity demand is highest in winter when production is zero. This seasonal mismatch significantly reduces solar's economic value in NO4.
