News on commercial solar, BESS and energy resilience
We publish practical briefings on the issues that change performance, risk and bankability. Czech legal details are linked to official sources; a briefing never replaces project-specific advice.
Technology radar
We read product updates as a change in options, not a sales instruction.
Signals from public company channels are checked against technical documentation and translated into project decisions.

New decision guides
Before you buy, replace or connect a battery
How to compare commercial battery storage proposals
Price per kWh is only a starting point. Compare usable energy, power, supply boundaries, service exclusions and the conditions behind promised benefits.
Read the guide →When commercial BESS makes economic sense — and when it does not
The business case starts with the operating profile, not the battery price. Separate a defensible benefit from an optimistic spreadsheet.
Read the guide →Battery shutdowns and inconsistent SOC: evidence for diagnosis
Prepare useful information for a qualified assessment without confusing a symptom with the cause of a fault.
Read the guide →Battery passport 2027: new supply and existing installations
Preparing for industrial batteries above 2 kWh, separating different obligations and avoiding the misconception of an automatic ban on older systems.
Read the guide →Victron and Studer system service and modernisation
Retain a working inverter, change the controls or replace the battery bank? Decide using system condition, verified compatibility and operating needs.
Read the guide →BESS cybersecurity: access, cloud dependency and responsibility
Assess the control architecture and operating context. Country of origin or a generic “NIS2 ready” label alone does not establish security.
Read the guide →Paid technology advice · Before procurement
Assess the risk before choosing the supplier.
For municipalities, hospitals, water utilities, schools and businesses: define the quality, security and operating outcomes you need from PV and BESS. Agree a separate advisory scope before purchasing equipment.
