About

Balázs Kovács

I've spent over a decade at the world's largest energy trade shows, designing solar and battery storage systems, and watching how the gap between spec sheets and real-world performance plays out every day.

My work sits at the intersection of engineering and economics — I size systems, read through supplier claims, and translate the numbers into decisions that actually make sense for homeowners, businesses, and investors.

The energy transition is full of noise: vendor marketing, oversimplified comparisons, and advice that ignores local context. My goal is to cut through that — with honest data, real calculations, and a perspective shaped by direct experience in the field.

This is Watt & Reality — the watts behind the story.

Topics

What we cover

01

Concepts, clearly

kW, kVA, kWp — what they actually mean and where they mislead you in quotes and proposals.

02

Reading proposals

How to evaluate a solar offer — production estimates, payback periods, and hidden line items.

03

Storage strategies

Self-consumption, peak shaving, arbitrage, backup — which strategy works for whom.

04

Sizing systems

How large a system do you actually need — for homes and industry, based on real load profiles.

05 ∞

More to come

Everything that belongs in this space — from theory to practice. This is an ongoing, continuously growing story.
