Frequently Asked
How does the Solar Payback & ROI Calculator work?
Our Solar Payback Calculator models the estimated Return on Investment (ROI), payback period, and 25-year cumulative savings for solar photovoltaic (PV) systems in the UAE. It integrates local utility tariffs (e.g., DEWA slab tariffs for Dubai, ADDC for Abu Dhabi) and matches them against your monthly consumption. It also accounts for net-metering credits, annual degradation rates (typically 0.5% for Tier-1 panels), and local engineering design factor averages.
What variables are modeled in the EV Charger Cost & Load Calculator?
The EV Charger Calculator calculates both hardware deployment costs and panel load additions. It determines the required breaker size (Amps) based on the charger's kW output (e.g., 7.4 kW single-phase, 22 kW three-phase) and integrates safety margins (applying 125% continuous load rule per NEC/DEWA regulations) to prevent overloading your facility's main distribution board (MDB).
How does the Battery Storage (BESS) & UPS Simulator calculate autonomy?
The BESS simulator models backup battery runtime based on critical load profiles, battery capacity (kWh), depth of discharge (DoD, typical 80-90% for Lithium Iron Phosphate), and inverter conversion efficiency. It is optimized for sizing peak-shaving architectures and emergency backup for critical facilities like data centers, healthcare, and high-uptime commercial centers in the UAE.
What standards are used for the Lighting (Lumen) Planner?
The lighting planner calculates the total required Lumens for any room using the formulas from international lighting standards (CIBSE / IESNA) and local UAE green building regulations. By specifying the target Lux level (ranging from 100 Lux for warehouses to 500 Lux for corporate offices) and room dimensions, it maps the required number of LED fixtures to achieve uniform distribution.
