wattbench is the applied altitude of the Solar Analytica network: the working reference for installers, electricians and owners standing in front of real hardware. It answers one question: how do I work with the equipment in front of me.
When an inverter throws a code at 7 am, the answer usually lives in a service portal the owner cannot access, a PDF buried three menus deep, or the memory of whoever installed it. The gap gets filled by whoever answers the phone first, and the advice that follows has a quote attached. Working systems get replaced because looking something up was harder than selling something new.
wattbench exists to close that gap with a reference instead of a funnel. The cleanest energy a solar system will ever make is the energy from hardware that stays in service, so the bench is built repair-first: decode the fault, understand the technology, run the numbers yourself. No account, no lead capture, and no one on commission between you and the answer.
The bench opens with the reference layer built on Solar Analytica, counted live from the library itself.
Per-brand libraries that decode the error on the screen: what it means, what to check, and when to call someone licensed. Written from manufacturer documentation, in plain English.
The technology behind the panels, from cell busbars to export limiting, written to inform a decision rather than close a sale.
Sizing, payback, voltage drop, tilt and orientation. Every formula is shown, everything runs in the browser, and nothing you type is stored.
The library is moving from Solar Analytica to its own bench at wattbench.ai. Until the move completes, everything above stays reachable here through the field guides and tools indexes, and through search.
Solar Analytica reads the market and the climate it runs on; review.solar scores what you can buy; wattbench is where the chosen hardware gets installed, understood and kept alive. Three properties, one evidence layer, one standard: every number names its source, and nothing is written to sell.
The applied bench: fault codes decoded, technology explained, numbers you can run yourself.
