Solar & EV calculators for Saudi Arabia

Five calculators, one page each, with SAR defaults. Every default carries its source and date on the field itself, every field is editable, and every page shows the arithmetic it uses plus the things it cannot see. We sell no hardware and take no installer commission, so there is nothing here nudging you towards a bigger system.

7 inputs across these calculators ship blank on purpose. No source we can cite publishes them for Saudi Arabia — generation per installed kW is the big one — so rather than pre-fill a plausible number, the calculators wait for yours and print nothing until they have it. Each page says exactly which figures are missing and why.

Rates carry their own dates: Saudi Arabia tariffs and pump prices move on their own schedules, so a single site-wide review date would be misleading. See how we verify a number before we print it.

Why there are only five

Because five is how many we can stand behind. Each one is wired to a figure someone else published — the utility’s own tariff, the month’s announced pump price, a dated listing in our Saudi Arabia price survey — so you can check every default rather than trust it. Where nobody published the number a calculator needs, we say so on the page and leave the field empty instead of filling it with something that would look identical to a verified figure. Start with the Saudi Arabia guides if you want the reasoning behind a rate before you use it.
