Given the high intensity of the sun in the UAE, and the ever increasing charges for electricity, now is the best time to change to solar hot water. As a developer, architect, MEP engineer or homeowner, it’s important for you to know how much you can be saving with solar thermal.
And that is where a solar water heater calculator can help. It’s a quick, data-driven method to estimate the financial and environmental value. We explain how our calculator functions, what it takes into account and why the tool is a crucial step in planning for sustainable energy in the UAE. Just scroll down to the section for our solar water heater calculator for the UAE.
What is the importance of Solar Hot Water in UAE
A typical villa can be a big energy guzzler, with hot water being one of the biggest loads and that applies to hotels and residential compounds too. Conventional electric heaters are energy vampires and its mileage may covary on the cost of the electricity resulting in increased energy hampers and high electricity bills.
Solar water heaters are a clean, renewable solution to this problem. They slashed electricity usage and provided consistent hot water all year long by capturing the sun’s energy.
The Perfect Place for Solar Thermal The United Arab Emirates is the perfect place for solar thermal technology.
Over 300 sunny days per year
Large averagely daily value of the solar power flux (5.5–6.5 kWh/m²/day)
Low Slope – Built Up Roofs Furnace Collector Installation Friendly
Enabling green building codes Estimating the carbon savings from the mandatory code vs the voluntary could not be established, since the code was too recent at the time of policy assessment.
What is a Solar Water Heater Calculator?
A solar water heating calculator is an online digital tool that you can use to determine:
Projected annual electricity savings
Solar fraction of the demand of hot water
Size of system (number of collectors and size of hot water storage tank required)
CO₂ emissions reduction
Approximate return on investment (ROI)
This calculator usually integrates on-the-ground solar data with technical system performance and water use benchmarks for fast custom insights on your project or home.
Who Could Benefit From a Solar Water Heater Calculator?
Whether you are trying to build one villa or a 100-unit block of residential apartments, by using a calculator you’ll get clarity that will help inform your decision early in the process.
Ideal for:
Developers Compare solar vs electric running costs at design stage
Architects Design roof space and building into plans carefully
MEP engineers Size and specify systems for optimum performance
Homeowners Know what you can save before you install
Utilizing solar calculator can also help in achieving green building codes and getting approval on investments for LEED, Estidama, or Al Sa’fat certifications.
How Does the Calculator Work?
Well-designed so-FHf’ digital & solar models take complex energy models and make them simpler to use. This is how our below solar water heater calculator for UAE works:
-
Hot water requirements
Daily hot water demand (litres)
-
Location
City or emirate
-
Instant Results
Our UAE focused calculator estimates:
Recommended collector size (m²)
Annual energy savings (kWh)
Percentage of hot water demands covered with solar energy (%)
CO₂ saved (kg/year)
Payback period in years.
Advantages of Using a Solar Water Heater Calculator
The biggest benefits are speed and clarity. Instead of doing a bunch of math or using a handful of rules of thumb to calculate a home’s energy savings, it gives you customized results in just a few seconds.
Key benefits include:
✅ Custom estimates for your home type and location
Visualise Your Return On Investment Based On Actuals
StrongAce / Enable cash flow for design decisions in the early stages of a project
✅ Factor in green building certification
✅ Increase client buy-in with transparent performance statistics
Solar Thermal vs Electric Heating: UAE Cost Comparison
To put things in perspective, consider this:
System Type |
Typical Annual Energy Use |
Estimated Cost (AED/year) |
CO₂ Emissions (kg/year) |
---|---|---|---|
Electric Water Heater |
4,500–6,000 kWh |
2,000–3,000 |
~2,000–2,700 |
Solar Water Heater |
<500 kWh (backup only) |
<300 |
<200 |
By allowing you to check whether a solar thermal system will be a good fit in the first place, it becomes a core component to your decision-making process. Sun-powered water heaters reduce electricity consumption by 90% at sun-soaked summers.
The initial investment may be slightly higher, but the payback is usually 3 – 5 years especially if combined with home made systems (like SolarisKit’s) which are locally manufacturable.
Why Use the SolarisKit UAE Solar Calculator?
At SolarisKit we designed our solar water heater calculator for homes and buildings in the UAE. It accounts for:
Local solar intensity
Water quality (hard/mineralised water compatibility)
Flat-roof installations
* Expandable modular to 200L to 1000L/day.
Our unique HelioFlow solar collector patented across the GCC not only arrives in a flat pack and is easy to install, it has been designed to perform to its maximum capacity in the GCC’s intense heat, which can be a problem with some such systems.
Sustainable Energy Made Simple
Each kilowatt-hour saved through solar water heating mitigates fossil fuel reliance and contributes to the UAE Net Zero 2050 plan.
- Here’s what a solar thermal system does:
- Reduces peak grid demand
- Lowers carbon footprint
- Saves water by eliminating cooling tower losses
- In line with green building goals (LEED, Estidama, Sa’fat)
- For new-builds and retrofits, it’s a smart, future-proofing decision.
Frequently Asked Questions
Is solar hot water worth it in UAE?
Absolutely. It’s one of the best value add-on energy upgrades, given the high solar potential and rising energy costs.
Do solar water heaters work when there is no sun?
Yes, they still work but less well. Electric backup is an option on most systems for complete reliability.
Is the calculator accurate?
We have our calculator based on conservative estimates as well as actual solar data to ensure accuracy. You will receive a system design when we visit to site.
What is the amount of roof space required?
Most Villa’s need 2-4 m² oF Roof per 200 liters of Hot Water. Our system is also space saving and is suited for flat roofs.
