PHT energy guides
Practical knowledge for better energy decisions.
The articles combine technical principles, decision tools, regional planning and interactive calculators without generic promises of returns.
Begin with one question: which form of energy is needed, at what time and for what purpose? Direct use, storage, heat, mobility, dynamic tariffs and optional flexible loads can then be compared sensibly.

Frequently asked questions
Frequently asked questions
Are these guides quotations?
No. They explain planning logic and assumptions. A binding solution needs property-specific data and a technical review.
How current is the information?
Each page shows an update date. Tariffs, incentives, rules and mining revenues must be checked again before a decision.
Why does PHT discuss risks?
Good advice separates technical feasibility, economics and personal objectives. Disadvantages and uncertainty are part of an informed decision.
Would you like to know what is possible for your property?
Your address, annual consumption and photos of the roof, meter cabinet and plant room are enough for an initial assessment.
