Solar & EV calculators for UAE
Five calculators, one page each, with AED 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.
5 inputs across these calculators ship blank on purpose. No source we can cite publishes them for UAE — 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: UAE 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.
Solar system size calculator
Turn your DEWA units into a kW figure and a battery size. The generation field is yours to fill — DEWA publishes irradiation, not output.
EV vs petrol running-cost calculator
Petrol against electricity per month, at August 2026 UAE pump prices and DEWA’s published tariff.
Panels needed to charge an EV or e-bike
How many panels cover your car’s daily charge in the UAE — once you supply the per-panel yield nobody publishes.
Solar battery payback calculator
What a battery saves under Shams Dubai — and why, at a 1:1 export credit, the honest answer is nothing.
Net metering vs net billing calculator
What a Shams Dubai system is worth a month, split between the units you use and the units you bank as credit.
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 UAE 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 UAE guides if you want the reasoning behind a rate before you use it.
