Pricing questions
Before you subscribe
Is the price per user or per company?
Per user. One subscription means one access key and one data space. If several people need to work in parallel, each needs their own subscription — sharing a key means sharing a single data space, which leads to conflicts.
Is the number of sites or calculations limited?
No. Add as many sites and run as many calculations as you like. The plans differ in the depth of features, not in volume.
Can I change plan later?
Yes. You can upgrade at any time with a pro-rata settlement — your data stays intact. Downgrades take effect from the next billing period.
What happens when the subscription ends?
Your data is not lost immediately: during a grace period you can still sign in and export it, only new calculations are blocked. The exact period is set out in the terms of service.
Why does it cost this much?
Professional tools in this field sit in the same band: PVsyst and PV*SOL around €700–850 per year, and HOMER Pro — the closest match in capability — above €2,000. SiteEnergy adds Hungarian regulatory reporting, a Central European tariff catalogue and energy-community settlement, which none of them provide.
How can I pay?
By card with immediate activation, or by bank transfer against a pro-forma invoice for business customers. Every payment is invoiced under Hungarian rules.
