Photovoltaics
Clean power from your own roof.
From idea through permitting to handover. Photovoltaic systems from 5 kWp to over 1 MWp — everything from one source, honestly planned, cleanly installed.
So arbeiten wir
From idea to your own power production
Consultation
Free on-site appointment. We measure the roof and your electricity consumption, discuss goals and incentives — honestly, with no sales pressure.
Planning & quote
Sizing based on roof geometry, orientation, consumption profile and future load (EV, heat pump). Transparent quote with payback calculation.
Installation
Permitting, mounting, electrical connection and commissioning — all by our own team. Usually done in 2 – 4 days.
Monitoring & service
Live monitoring via Huawei FusionSolar. Maintenance and yield guarantee included — we stay involved after commissioning.
Anwendungen
The right system for every scale
Residential
5 – 30 kWp
Single- or multi-family home. Perfect combination of self-consumption, battery storage and wallbox — often paid off in 8 – 12 years.
- Pitched, flat roof or façade
- Longi modules + Huawei inverter
- Optional LUNA2000-21-S1 and heat pump
Commercial
30 – 300 kWp
Commercial roofs often pay off faster than residential systems — thanks to high self-consumption during business hours.
- Flat and shed roof mounting
- Self-consumption optimisation and ZEV
- Load management and BESS integration
Industry & open ground
from 300 kWp
Large-scale systems on production and logistics roofs, combined with BESS for grid relief and peak shaving.
- Open-ground and rooftop systems
- Integration with 2 MWh+ BESS
- Direct marketing and power-purchase agreements
Häufige Fragen
What our customers ask most often
What does a photovoltaic system cost?
A typical single-family home system with 10 – 15 kWp costs between CHF 25,000 and CHF 40,000 including mounting and commissioning. Cantonal incentives and one-off remuneration further reduce this by 15 – 30 %. Our quote transparently shows components, labour and payback time — pragmatic, no hidden items.
How long does the installation take?
We usually install single-family home systems within 2 – 4 days. Larger commercial and industrial systems take longer. Permitting and grid connection applications are planned in advance so things run smoothly on site.
Does a battery make sense on top?
Without a battery you sell surplus power back to the grid at a lower rate than you buy. With a battery, self-consumption rises from around 30 % to 60 – 80 %. Whether it pays off depends on your consumption profile — we calculate both variants in the quote.
Which manufacturers does Bergler use?
Modules: Longi (premium, 25-year warranty). Inverters: Huawei FusionSolar (high efficiency, integrated monitoring). Residential battery storage: usually Huawei LUNA2000-21-S1 (21 kWh LFP). For off-grid setups we additionally use Pytes and Victron.
What happens during a power outage?
With a standard inverter, the system shuts down during a grid outage for safety reasons. With a Huawei backup module or a Victron off-grid system we set up uninterrupted backup power — useful for heat pump, fridge, lights.
