1. Based in Pfäffikon SZ
PHT Energietechnik is based at Churerstrasse 158 in Pfäffikon SZ and serves Freienbach, Wollerau, Lachen, the Canton of Schwyz, the Lake Zurich region, Glarus and neighbouring areas.
Regional proximity supports surveys, coordination and later optimisation, while every project is still assessed for feasibility and capacity.
2. Grid connection and tariff are local
The grid operator, metering, connection power, export remuneration and tariff can differ and change. Conditions are therefore checked for the property address; Swiss averages are only a starting point.
Under dynamic or demand-based tariffs, the local formula becomes part of the control strategy.
3. Building and topography
Roof orientation, mountains, trees, neighbouring buildings, snow, wind and roof features affect output and installation. Sites around Lake Zurich or near the Alps can have different shading and loading conditions from open locations.
Plant rooms also vary. Storage, heat pumps, hydraulics and cable routes must fit the actual space.
4. Regional project check
The address, consumption and photographs are enough for an initial classification. PHT then reviews the grid operator, likely PV layout, heating, storage and priorities.
- Property address and ownership
- Annual consumption and major loads
- Roof, meter cabinet and plant room
- Heating, hot water and expansion plans
- Local tariff and grid connection
5. Genuine local content rather than location lists
This page describes the service area without promising the same solution in every municipality. Useful local content comes from actual projects, data and grid conditions, not automated near-duplicate pages.
