Benefits of Our Off-Grid Solar Calculator đđ
â Precise Sizing
Avoid the common mistake of oversized systems that cost more than necessary or undersized ones that fail to meet your needs. Our calculator uses advanced algorithms based on your real energy consumption to recommend the exact system size.
đ° Significant Savings
Users of our calculator save an average of 30% on installation costs by avoiding the common oversizing of off-grid solar projects. Proper system sizing ensures you invest only in what you truly need.
âī¸ Complete Customization
Unlike generic calculators, our tool allows you to input your specific appliances with exact power ratings and real usage patterns. The result is a truly personalized system tailored to your unique situation.
đ Data-Driven Decisions
Make informed decisions about your solar energy investment with clear data on the number of panels, battery storage capacity, inverter specifications, and return on investment.
đ Planning for Energy Autonomy
Define exactly how many days you need to operate without sunlight and size your battery bank accordingly. This ensures system reliability even in adverse weather conditions.
đŋ Environmental Impact Assessment
See the positive impact of your solar system on reducing COâ emissions and its equivalent in trees planted, helping you quantify your contribution to sustainability.
đ Scenario Simulation
Easily compare different system configurations by adjusting components or usage patterns, helping you find the perfect balance between investment and performance.

Calculator Usage Instructions
Add Your Appliances
What to do? List all electrical devices you will use in your off-grid system.
How to do it?
- Click on the buttons to quickly add common appliances (e.g., "Refrigerator 150W").
- If your appliance is not listed, click "+ Add Appliance" and enter:
- Name (e.g., "Laptop")
- Power (W) (Check the label on the device)
- Quantity (How many of this device you have)
- Hours per day (How many hours it runs daily)
Set Your Location (Sunlight Hours)
What to do? Enter the average daily sunlight hours your solar panels receive.
How to find this information?
- If unsure, check an online solar map or use this guide:
- đ Sunny areas (deserts, tropics) â 6 to 8 hours/day
- â Mild climates (temperate regions) â 4 to 5 hours/day
- đ§ Cloudy or winter conditions â 2 to 3 hours/day
Choose Your Components
What to do? Select the right components for your solar system:
- Solar Panel Power (More Watts = Fewer panels needed)
- Battery Type (Lithium lasts longer but costs more; Lead Acid is cheaper but bulkier)
- Battery Capacity (Ah) (Higher = More stored power for night use)
- Battery Voltage (Common values: 12V or 24V)
- Days of Autonomy (How many days should your system work without sunlight?)
Tip: If unsure, keep the default values.
