Best for
Asset managers and O&M teams running large solar, wind and battery sites.

Our quick verdict

GPM Horizon helps you run big wind, solar and battery plants from one web tool. It tracks output, lost power, budgets, money earned and repair tickets. The main drawbacks are no public price and few public details on security or an API (a way for other apps to pull data).

Best for

Asset managers and O&M teams running large solar, wind and battery sites.

Not ideal for

Home or small business installers, and buyers who need public pricing.

Biggest strength

It shows where power is lost, down to each string of panels, and links it to money.

Biggest weakness

No price on the website, and we found no public API or security documents.

Top alternative: meteocontrol VCOM. Pick it for EU hosting, a public API and a built-in CMMS.

What can DNV GPM Horizon help you do?

  1. 01

    Watch the whole portfolio

    The Overview and Monitor modules show live KPIs (key numbers like output and uptime). You can look at the whole portfolio or one inverter. KPIs update every five minutes.

  2. 02

    Find where energy is lost

    Analysis works out lost power from five-minute data, down to each string of panels. A waterfall chart shows the main cause of the loss.

  3. 03

    Track budgets and revenue

    Budgets compares output with plan. Revenues turns KPIs into money using market data and each project’s setup.

  4. 04

    Manage alarms and tickets

    If an alarm stays on longer than the time you set, you get a notice. You can turn it into a ticket. Tickets use kanban boards, chat and templates. You can also create tickets in your repair team’s CMMS (maintenance work-order app).

  5. 05

    Report contract KPIs

    The Logbook sorts events with an 80-class model from the IEC 61400-26 standard. The KPIs module then works out availability (how often the plant could run) with your own formulas. This helps you report against contracts.

Key features

Each feature shows what we found on DNV GPM Horizon’s own website, and how sure we are.

Power estimate

Basic

Compares actual with predicted and theoretical output, with weather correction. Not a design simulator.

Financing

Basic

Revenues and Budgets track money earned against plan. The page says it shows the real PPA (power sale deal) and contract availability. It does not offer loans.

Project management

Not found

We found no project tools for building plants.

Battery design

Company claim

A Horizon Storage module covers battery systems. We did not read its page.

Monitoring

Advanced

Live KPIs, alarms and analysis from portfolio to inverter, with losses to string level.

Operations and repair (O&M)

Basic

Tickets with kanban boards, chat and templates help repair teams track work. Planning is in the Elite tier.

Integrations

Company claim

The company says you can create tickets in your repair team’s CMMS. It does not list named partners.

API

Not found

We found no public API docs.

AI and automation

Company claim

Gemini uses AI to spot anomalies. For wind it uses vibration data. For solar it finds underperformance.

Mobile

Basic

A mobile app is listed in the Elite tier.

Reporting

Advanced

Drag-and-drop reports and templates. Scheduled PDFs can be emailed to a list.

Not what DNV GPM Horizon is for, so not scored: Solar design, 3D modelling, Shade analysis, Proposals, CRM, Lead management, Permits and plan sets.

Our assessment

Gemini’s AI is mostly for wind turbines, where experts check its results to cut false alarms. For solar, it is described as advanced analytics that finds underperformance and splits losses. That is useful, but it is not a chat assistant.
