About pricing

SteadyWeb is our comprehensive web-based platform that provides access to accurate solar and wind power forecasting data. 🌥️🛰️ This user-friendly interface allows you to:

  • Monitor live production forecasts with updates every 15 minutes
  • Access historical weather and production data for analysis and planning
  • Export data in multiple formats for integration with your existing systems
  • Manage multiple renewable energy assets from a single dashboard

Whether you’re operating a single solar installation or managing a portfolio of renewable assets across different regions, SteadyWeb provides the forecasting intelligence you need.  🚀

The platform is designed for energy professionals who require reliable, actionable weather and production data.

During your 30-day free trial, you get full access to our forecasting platform with no restrictions as an EXPERT+ subscription. 

You can test the accuracy of our forecasts against your actual production data, evaluate how our predictions perform in your specific climate conditions, and experience the full functionality of our platform. 💪

No credit card required to start, and you can cancel anytime during the trial period.

The platform features an intelligent subscription management system that dynamically adapts to changes in your monitoring portfolio. 🔄

When you add new sites, your subscription automatically updates within a one-hour modification window. A new invoice is generated immediately, covering the remainder of your current billing period and extending to the end of your initial contract (monthly or annual). Volume discounts are immediately applied to ensure cost efficiency as your portfolio grows.

For site reductions, your contract updates at the conclusion of your current billing term (monthly or annual), avoiding disruption to ongoing operations.

The system also includes a “site credit” feature — if you remove sites and later add an equal or lesser number within the same billing period, no additional charges apply.

Here are some examples:

  • On October 1st, I subscribe to a monthly advance+ contract with one site, paying 34€. On the 15th of the month, I add a second site, and I’m billed €12 immediately (€24 prorated for the remaining month). On November 1st, my subscription is updated to 58€.
  • At 1pm, I add 10 sites to my portfolio, including 5 by mistake. I rectify this at 1:30pm: I’m billed for 5 sites at 2pm.
  • I add 10 sites to my portfolio by mistake at 1pm, I rectify at 1:30pm: I’m not billed for anything.
  • I have a 10-site annual subscription contract (June to June), I delete 5 sites in September, my subscription will be updated in June. However, I can add up to 5 sites free of charge between now and June.

On our forecasting plateform we accept only one secure payment methods: Credit and debit cards (Visa, Mastercard…).

All payments are processed through secure, encrypted channels to protect your financial information.

For enterprise customers with specific billing requirements or multi-year contracts, we can arrange customized payment terms. Contact our sales team.
