PV matched to the roof, demand and grid.
A system, not separate devices
Solar PV, storage and heat work together.
PHT designs the energy flow from roof to battery, heat, mobility and grid with clear priorities and open expansion paths.

Quick answer
A good system remains understandable, handles faults safely and can be expanded later. The electrical route, heating hydraulics, communications, spare space and responsibilities are therefore documented together.
A system, not separate devices
Four design questions
Store
Use electrical and thermal storage for the tasks they suit.
Consume
Prioritise the building, business, heating and mobility.
Control
Combine metering, automation, monitoring and safe fallbacks.
Process
From the first photograph to a working installation.
Assess the building
Record the roof, plant room, meter cabinet and heat distribution.
Model the loads
Represent electricity, heat, mobility and planned extensions.
Define the architecture
Set components, interfaces, protection and priorities.
Deliver in stages
Phase investment without creating future dead ends.
A system, not separate devices
Four design questions
When is energy needed?
Daily and seasonal profiles determine the value of PV, storage and heat.
What simultaneous power is required?
Connection capacity matters as much as annual kWh.
Which devices need to communicate?
Open, documented interfaces reduce dependence.
What will be added later?
EVs, more PV, storage or heating need spare capacity.
Local SEO · GEO
Serving Pfäffikon SZ, Freienbach, Wollerau, Lachen, the Canton of Schwyz, the Lake Zurich region, Glarus and, depending on the project, wider areas.
Local SEO should not consist of copied town pages. A real project depends on the grid connection, current tariffs, shading, building services, permissions and measured demand. PHT combines these local facts with an integrated system design.

Frequently asked questions
Frequently asked questions
Must everything be installed at once?
No. A full concept can be delivered in stages if interfaces, space and power reserves are considered early.
Autonomy or economics: which matters more?
That is a project objective. Maximum autonomy is not automatically the most economical result.
Can equipment from different manufacturers be combined?
Yes, where interfaces are documented and compatible.
How does the system remain maintainable?
Through clear documentation, labelled equipment, understandable rules and safe default states.
