☀️ Peak sun hours in Austria by region
Peak sun hours (PSH) is the number of hours per day the sun delivers 1000 W/m². Austria averages about 3.4–3.8 PSH — the eastern lowlands and the deep south (Carinthia, Styria valleys) are sunniest, while the Alpine west is a little lower. Like all cool-climate countries, panels here perform slightly better per watt in summer than identical panels in the desert. See our guide on peak sun hours by location.
| Region | Approx. peak sun hours (annual avg) |
|---|---|
| Vienna & eastern lowlands | ~3.6 – 3.8 |
| Styria & Carinthia valleys | ~3.5 – 3.8 |
| Salzburg & Upper Austria | ~3.4 – 3.6 |
| Tyrol & the alpine west | ~3.2 – 3.5 |

⚡ Electricity tariff and PV support in Austria
Austrian household electricity runs roughly €0.20–0.30 per kWh depending on the state utility. The federal Photovoltaikförderung programme pays a direct subsidy per kWp installed — a meaningful share of system cost — and most states add their own bonus on top. Export is bought at market-linked rates (~€0.05–0.10/kWh), so, like Switzerland, the game is self-consumption, and batteries are strongly supported with their own subsidy. Estimate your saving with the solar bill savings calculator.
💡 Why the federal programme makes payback fast
With the federal + state subsidies deducted, a typical Austrian 5 kW system pays back in roughly 5–8 years — fast for a cool-climate country. The reason: generous upfront support, high retail prices, and a market where quality installation is the norm. Read our grid-tied vs off-grid vs hybrid guide — in Austria the answer is almost always grid-tied with battery.
💰 System cost & payback in Austria
As a rough planning guide (verify with local quotes — prices move):
| System size | Approx. installed cost | Suits |
|---|---|---|
| 3 kW | ~€5,500 – 7,500 | Small home, low usage |
| 5 kW | ~€8,500 – 11,500 | Typical family home |
| 10 kW | ~€15,000 – 19,000 | Large home / small business |
After federal and state subsidies, effective payback is commonly 5–8 years — then 20+ years of cheap power. Work out your own numbers with the ROI calculator and size the array with the panel calculator — or design the whole system at once with the system report builder.
🛠️ Field note
Austria's lesson: subsidies change everything. Apply for the federal Photovoltaikförderung before ordering — the programme runs in rounds and quotas fill fast, and retroactive claims are not accepted. And when you size the system, size it for the household's own consumption curve, not for export: the export tariff pays a fraction of the retail price, so every kWh the battery shifts from day to evening is worth roughly three times an exported kWh.

❓ Frequently asked questions
Is solar worth it in Austria?
Yes — with the federal PV subsidy plus state bonuses, a typical 5 kW system pays back in roughly 5–8 years and then produces for 25+ years.
How does the Austrian PV subsidy work?
The federal programme pays a per-kWp investment subsidy, applied for before installation; most states add a bonus. Quotas fill fast, so apply early and never install before the grant is approved.
How does net metering work in Austria?
Austria does not use classic 1:1 net metering. Export is bought at ~€0.05–0.10/kWh while you buy at €0.20–0.30, so systems are sized for self-consumption, often with a battery (which has its own subsidy).
How much does a 5kW system cost in Austria?
Roughly €8,500–11,500 installed before subsidies; the federal + state support typically cuts the effective cost by 20–35%. Get local quotes.
