Terms of use

Terms for using Voltira

Effective from 6 October 2026 · Version 1.3

1. Who we are

Voltira is operated by Voltira v/Zoran Knezic, CVR 38539019, Ålborggade 6, 3rd floor right, 8000 Aarhus C, Denmark, email kontakt@voltira.dk. By using the service or buying a report you accept these terms.

2. The service

Voltira estimates what a battery could earn at a specific site from your consumption, your grid company's tariffs and historical Danish market prices. You can get a free answer — yes, borderline or no — without creating an account. You buy the full report as a one-time payment; it is kept on an account you create when you buy. We may change, improve or temporarily suspend the service. If we close it for good, we will give notice in good time so you can save your reports.

3. The tool and the report are an estimate — not advice

  • Voltira is a calculation tool. What you buy is a report: an estimate from your own data and public prices. The same applies to the recalculations you make yourself in the tool (another battery, a quote, solar panels).
  • The report is an independent analysis and estimate based on your data and the assumptions stated in it. It is not financial, investment, legal, tax or technical advice and not a guarantee of future earnings.
  • Future prices, market rules, tariffs and bid acceptance may develop differently from our assumptions — including outside the scenarios the report shows.
  • Results depend on the quality of the data you upload and enter.
  • Before investing, obtain supplier quotes and have your connection, tariffs and any grid upgrade confirmed by your grid company.

4. Your account

Accounts are personal. Keep your password secret and don't share your login. Tell us immediately if you think someone else has gained access.

5. Acceptable use

You may use the service to assess batteries for your own sites or your clients' sites. You may not:

  • copy, imitate, decompile or try to derive the model, methods or code behind the service;
  • run automated or systematic queries (e.g. many constructed files) to map how the model behaves;
  • resell the service or give others access through your account;
  • upload data you don't have the right to use.

We may limit the number of reports and suspend accounts in case of misuse.

6. Rights

All rights in the software, models, methods, texts and design belong to Voltira. You may use your own reports for your own purposes and share them with your advisers, suppliers and financing partners.

7. Your data

You confirm that you have the right to upload the data you use (e.g. consent from the site owner). We process data as described in our privacy policy.

8. Price, payment and delivery

  • The price is shown before you buy. It is a one-time payment — there is no subscription.
  • You pay on Stripe's secure payment page (card, Apple Pay, Google Pay or MobilePay where available). Stripe emails the receipt.
  • The report is delivered immediately after payment: you choose a password, and the report opens on your account. The link is also sent by email.
  • The purchase includes a number of recalculations of the same file (e.g. another battery, a quote or solar panels). The number is shown when you buy.

9. Right of withdrawal

If you buy as a consumer, you normally have a 14-day right of withdrawal when buying online. The report is digital content delivered immediately. When you ask for immediate delivery at checkout and confirm that you thereby lose your right of withdrawal, the right lapses as soon as delivery has begun. We confirm this by email after the purchase. Purchases by businesses carry no right of withdrawal.

10. Errors in the report

If there is an error in your report — e.g. a calculation that didn't go through correctly — write to kontakt@voltira.dk and we will correct it. As a consumer you always keep your rights under Danish consumer law.

11. Liability

  • We take care that calculations are correct, but we cannot guarantee error-free operation.
  • We are not liable for indirect loss, such as lost profit, or for decisions made on the basis of a report.
  • Our total liability is limited to the amount you paid for the report the claim concerns.
  • These limitations do not apply in case of intent or gross negligence, and they do not limit your mandatory rights as a consumer.

12. Termination

You can ask us to close your account at any time. We may close or suspend accounts that breach these terms.

13. Governing law and complaints

Danish law applies. Disputes are settled by the Danish courts. If you are unhappy, please write to us first at kontakt@voltira.dk. Consumers can also complain to the Danish Consumer Complaints Board (Nævnenes Hus, Toldboden 2, 8800 Viborg) via forbrug.dk.

14. Changes

We may change these terms. We will give notice of material changes before they take effect.
