How much does a solar system cost?

Short answer

A residential solar PV system in Romania costs, in 2026, between EUR 5,500 and EUR 11,000 turn-key for capacities of 3 kW to 8 kW. Variation comes from system size, panel and inverter brands, presence of a battery, and roof complexity.

What's included

A turn-key quote typically covers:

• the PV panels (usually monocrystalline 400–460 W),
• the inverter (string, or hybrid if you want a battery later),
• the rooftop mounting structure,
• DC/AC cabling, protections and switchboard,
• installation, commissioning, and the grid connection paperwork (avizul tehnic de racordare).

Batteries are usually not included by default. Adding a 5–10 kWh battery adds EUR 2,500–5,500.

The Casa Verde Fotovoltaice subsidy

Romania's AFM Casa Verde Fotovoltaice program covers up to RON 20,000 of the cost of a new system for individuals. To qualify:

• the installer must be AFM-validated — every firm we list on our city pages is from the AFM list,
• the owner must be a private individual, with no debts to the tax authority,
• the system must be brand new and grid-connected,
• the application is filed through the installer during an active AFM session.

What drives the price

In order of impact:

1. Installed capacity (kW) — bigger systems have a lower per-kW cost.
2. Panel brand — Jinko, Longi, Trina, JA Solar, Canadian Solar are the volume options. Premium tiers (REC, SunPower) add 10–25%.
3. Inverter type — plain string inverters are cheapest; a hybrid inverter (battery-ready) is 20–40% pricier but keeps the door open for a battery upgrade.
4. Roof type — ceramic tile or slate raise installation cost vs. trapezoidal sheet metal.
5. Battery — optional and the most expensive component per kWh.

What's the payback?

With an average household consumption of 5,000 kWh/year and a 5 kW system, payback (after subsidy) is typically 5–8 years. Without subsidy, 8–12 years. Modern panels carry a 25–30 year production warranty, so after payback you get near-free electricity for another 15–20 years.
