Compare your two written quotes
Enter actual AED prices. No suggested market rate or automatic complexity multiplier.
One complete agreed project per quote. Quantities and unit rates must already be extended in the written amount.
Confirm the current DEWA-enrolled contractor, system specification, rated kWp, shading assumptions, roof ownership and connection responsibilities. Keep forecast kWh and financial assumptions outside this cost comparison. State who protects waterproofing and provides ongoing monitoring or maintenance. Use whole-project amounts, never unextended per-door, per-seat, per-kWp, per-square-metre or per-kilogram rates. Ask each provider to extend measured quantities, minimum charges and allowances into written totals first. Keep quantity 1. All provider amounts must share one confirmed VAT basis; normalize mixed tax bases before entry. Customer purchases use final receipt amounts. Deposits are not discounts or visit credits; refundable deposits and fees paid directly to an authority remain outside this result. Add only extras excluded from the main package.
Amounts: AED 0–1,000,000 without commas, up to two decimals. Blank remains unknown. These input limits catch mistakes; they are not market ranges.

Comparison pending. Complete both totals and all scope confirmations. An unconfirmed part, compatibility check or extra is not zero.
This tool does not approve a PV design, structural loading, roof works or grid connection, and it does not certify savings or payback. Use current DEWA requirements and an appropriately enrolled contractor. A service listing is not evidence of contractor enrolment or site eligibility.
