Photovoltaic panels
Personalized study, installation, connection and Walloon subsidies procedures. Produce your own electricity with peace of mind.
With soaring energy prices and attractive Walloon subsidies, photovoltaic becomes a profitable investment in less than 7 years, with 25-year guaranteed production.
Smart Ohm handles the complete installation: productivity study, module selection, roof installation, inverter, grid connection, and administrative procedures with your network operator (ORES, RESA).
We install both residential installations (4-12 kWc) and commercial (up to 100 kWc) with optional battery storage to maximize self-consumption.
An installation that produces, really
Accurate productivity study
Software simulation with orientation, inclination, shading. You know exactly what you'll produce each month.
Optimized subsidies
We handle all Qualiwatt procedures and Walloon subsidies. Maximizing aid based on your situation.
Premium equipment
JinkoSolar, JA Solar modules, SolarEdge or Huawei inverters. 12-year product warranty, 25-year performance warranty.
Production monitoring
Smartphone app to monitor your production in real time, alerts if abnormal drop.
From quote to first kWh
Technical study
Roof visit, measurement of orientation/inclination, production simulation with approved software.
Quotes & Subsidies
Firm quote, subsidy simulation, return on investment calculation year by year.
Installation
Installation in 2-3 days by certified team. Roof securing, waterproofing guaranteed.
Connection
ORES/RESA procedures, compliance check, commissioning and monitoring app configuration.
From home to industrial roof
Residential
Typical installation 12-24 panels (5-10 kWc) on single-family home. Budget €8,000 - €15,000 before subsidies.
Co-ownership
Shared rooftop installation, self-consumption shared between co-owners (recent legal framework).
Company
Flat roofs or cladding, up to 100 kWc. Accelerated tax depreciation, ideal daytime self-consumption.
Are you wondering?
How many panels for my home?
On average 1 panel of 425Wc per 350-400 kWh of annual consumption. A consumption of 5,000 kWh/year = approximately 12-14 panels (5 kWc).
What's the return on investment?
With 2026 subsidies: 6 to 8 years for residential, 4 to 6 years for commercial. 25-year guaranteed production, so 17-19 years of net benefit.
What subsidies in 2026?
Wallonia: investment subsidy + degressive prosumer rate. Brussels region: subsidy + green certificates. We calculate your specific case.
My roof is partially shaded, is that a problem?
Not necessarily with SolarEdge optimizers which isolate losses per panel. We measure shading before quoting.
