bessaudit.com belongs to Sun.Energy Holding s.r.o. — a consulting group of energy-focused companies. We are neither a supplier nor an installer: we do not sell batteries, we do not install them and we have no stake in who wins the contract. We assess other people's projects using public ČEPS, OTE and ERÚ data. The tool stands on our own practice: we know where real projects get stuck.
Sun.Energy Holding s.r.o. is a consulting group of energy-focused companies. The group also includes the products sun.energy and energycars. Day-to-day work on real projects has taught us the technical, regulatory and economic side of battery and solar investments — and that is exactly the experience we are now turning into our own digital tool.
We assess photovoltaic plants and battery storage — technically and economically.
A complete data package for Czechia, with reach across the CEE region.
Our own tools, which we develop, operate and integrate.
Small and mid-sized BESS investors have no access to independent, fast and affordable analysis — large consultancies are expensive and slow, while vendors show only their own offer. We decided to close that gap with software built on real data and independence. It does not replace a human expert on large transactions — it is a tool that brings clarity to the vast majority of decisions in minutes.
Leads the vision and construction of the platform — from the product concept through market and regulatory data to the calculation core and the due diligence methodology.
