Terms of use

Last updated: October 2026

Calculators are estimates

The tariff and revenue-leak calculators give illustrative estimates only. The tariff calculator uses the residential rates revised in August 2026 and covers the energy charge only, excluding customer-service fees. Rates change by government decision, and real solar yield varies with location and installation. Any final quote to a customer is the responsibility of the company issuing it.

Pilots and engagements

The terms of any pilot or engagement (scope, duration, guarantee and price) are written down and agreed with each client before work starts. The website is a summary; the written agreement governs.

Content

The site's content and design belong to Velnix. You are free to use calculator results and send them to your customers.

Liability

The site is provided "as is". We are not liable for decisions made on calculator estimates without professional review.

Governing law

These terms are governed by the laws of the Arab Republic of Egypt.
