All About Solar-Calories by MOEI
As the United Arab Emirates advances its clean energy transition, digital tools help residents make informed decisions. One such initiative is Solar-Calories, a mobile application developed by the UAE Ministry of Energy & Infrastructure.
The app is designed to simplify solar energy planning by translating a homeowner’s current electricity usage into a structured solar system estimate. Rather than replacing professional consultation, Solar-Calories by MOEI serves as a preparatory tool that helps users understand their potential solar requirements before engaging with installers.
What is Solar-Calories by MOEI?

The primary objective of Solar-Calories by MOEI is to determine the appropriate solar system size based on a household’s actual electricity consumption.
This feature is particularly useful for homeowners considering buying a house with solar panels. To achieve this, the app breaks down the calculation into four key components:
PV Module Sizing
The app calculates how many solar panels are required and determines their combined wattage output based on the user’s daily energy consumption.
Inverter Sizing
It estimates the inverter capacity necessary to convert direct current (DC) electricity generated by solar panels into alternating current (AC) electricity used in homes.
Battery Sizing
For users considering energy storage, the app calculates the required battery capacity to provide electricity during nighttime hours or periods of low sunlight.
Solar Charge Controller Selection
The app identifies the appropriate charge controller size to regulate energy flow and prevent battery overcharging, thereby protecting system longevity.
How Solar Calories App Works

The application follows a clear and structured three-step workflow.
Step 1: Appliance Inventory (Home Tab)
Users begin by selecting household appliances from a predefined list, such as lighting, air conditioners or small electronics. For each appliance, they enter:
- Power rating (in watts)
- Number of hours used per day
The app then calculates the total daily energy demand in kilowatt-hours (kWh/day). This figure forms the foundation of the entire system estimate.
Step 2: Custom Configuration (Settings Tab)
To guarantee realistic projections, the app allows users to adjust key technical parameters:
System Losses
Accounts for energy losses during conversion and transmission. A default value is typically provided but can be modified.
Solar Conditions
Incorporates average daily solar irradiation specific to the user’s location, reflecting local sunlight availability.
Battery Specifications
Users can define:
- Days of Autonomy – the number of days the battery system should operate without sunlight
- Depth of Discharge (DoD) – limits on battery usage to preserve long-term performance
This customisation allows the system recommendations to align with practical operating conditions.
Step 3: Final Recommendation (Solar PV System Tab)
After entering all required information, the app generates a summarised system recommendation. This may include:
- Total number of solar panels required
- Total panel capacity (kW)
- Recommended inverter size
- Suggested battery capacity (e.g., ampere-hours)
The app may also provide access to regional solar mapping tools such as Shuaa (Emirates Solar Calculator) for more detailed location-based analysis.
Benefits of Solar-Calories Application
Solar Calories is particularly useful during the pre-consultation phase. It equips users with:
- A clearer understanding of their energy consumption
- Familiarity with technical terminology such as kWh, inverter capacity and depth of discharge
- Realistic expectations regarding system scale
