Scroll the table sideways. The product column stays in place.
A free, community-run site where solar owners upload their own generation data, compare it with neighbouring systems, and pull it back out through an open API — the honest answer to "is there free solar monitoring", and not a product in the sense the rest of THE 100 are products.
An Australian consumer-facing solar performance and savings monitor that models what a system *should* be producing from its own specifications and local weather, then flags the gap — sold by subscription per inverter, or free if you install the group's own CATCH Control hardware.
A renewables ERP built on Microsoft Dynamics 365 that sits *above* your existing SCADA and monitoring portals, turning their alerts into incidents, work orders, costs, PPA invoices and Power BI reports.
A German-engineered, manufacturer-independent cloud monitoring and technical-operations platform for PV and BESS portfolios, normally paired with the vendor's own blue'Log X-Series datalogger, with a documented public REST API.
A German PV monitoring and energy-management portal that is genuinely manufacturer-independent at the *inverter* layer — 3,800+ components across 179 manufacturers — but which, at the *logger* layer, still expects a Solar-Log Base device, with only two third-party logger brands supported so far.
A vendor-independent renewable energy management suite spanning SCADA, power plant control, EMS, asset performance management, field service and commercial/invoice management for utility-scale wind, solar, hydro and BESS portfolios.
A German manufacturer-independent PV monitoring portal that pulls existing loggers and inverter clouds into one login, with a genuine white-label option and no hardware of its own to sell.
A hardware-agnostic SaaS platform for monitoring, analysing and optimising solar, wind and BESS assets, built on a physics-based digital twin, sold by a Belgian company that also sells human advisory services and resource data.
An alternatives page that never says this is an advertisement for the alternatives.
PVOutput cost nothing to use. We do not rank them, because no product is scored until it carries eight verified reviews.
Tigo Energy Intelligence (EI) publishes Free. Budget and those limits are the documented reasons a buyer looks elsewhere — we do not speculate beyond what the data shows.
