Solar engineering that starts from your bill
Systems for homes, farms, factories and commercial projects across Saudi Arabia, sized on official tariffs and your city's yield, and reviewed by an engineer before any offer.
Find your solar system size and how much you can save
Enter your bill. We work out consumption from the official slabs after separating the fixed charge and VAT.
How we reach the number
Dividing by one price gives the wrong consumption when there are slabs and fees. These are our steps, all stated and adjustable.
Unpack the bill
We remove VAT and the breaker based fixed charge, then reverse the official slabs to reach your consumption.
Spread use over the year
An August bill is unlike a January bill, so we build a seasonal curve and separate day and night load.
Calculate your city's output
PVGIS monthly data for thirty Saudi cities, after technical, soiling and shade losses.
Compare three sizes
Economy, balanced and highest possible coverage, within area, breaker and net billing limits.
Tariffs change on 1 January 2027
The Saudi Electricity Regulatory Authority announced a new tariff with a higher breaker based fixed charge. The calculator applies effective dates and shows your bill on both.
Read the detailsOur services
Design, supply and installation, according to the site and its connection or storage needs.
Grid-tied systems
Reduce daytime use from the grid. Surplus follows net billing rules.
DetailsWater pumping
Submersibles and vertical or horizontal electric heads, with a preliminary panel estimate the engineer checks against pump and well data.
DetailsOff-grid systems
For remote sites, sized on the worst month with batteries for the night.
DetailsHybrid LV and HV
Panels, batteries and grid together, with backup during outages.
DetailsBatteries, inverters, panels
What to check in each component. Availability is confirmed on request.
DetailsCommercial and industrial
Load study and design around operating pattern, contract capacity and connection rules.
DetailsWhat we commit to
- No zero bill promise. The fixed charge and night use remain, and we show them clearly.
- Facts apart from estimates. Every assumption is stated, and you can change it and see the effect.
- An engineer reviews before any offer. The calculator gives an estimate, not a final design.
- Documented figures only. No achievement, certificate or project photo is published before it is documented and approved.
Calculators
Seven independent calculators, each with its own inputs and stated assumptions.
