Confused about solar panel sizing? Learn how to calculate the right wattage for your devices, avoid underpowered systems, and discover why 80% of first-time buyers regret not reading this first.

Why Solar Wattage Matters More Than You Think

Solar charging isn''t a one-size-fits-all solution. Choosing the wrong wattage could leave your devices starving for power or waste money on oversized panels. Let''s crack the code.

Key Factors That Determine Your Solar Needs

• Device power consumption: A smartphone needs 10-20W daily, while an RV fridge guzzles 150W+.
• Sunlight hours: Arizona delivers 6 peak hours vs. Germany''s 2.5 – adjust accordingly.
• Battery storage: No battery? You''ll need panels to match instant power demands.

Real-World Scenarios: From Camping to Home Backup

Use Case	Devices	Recommended Watts
Weekend Camping	Phone, LED lights	50-100W
Van Life	Fridge, laptop, lights	300-400W
Home Office	Router, computer	200-250W

The Math Made Simple

1. List all devices: Phone (10W) + Laptop (60W) = 70W total
2. Multiply by daily usage hours: 70W x 5h = 350Wh
3. Divide by peak sunlight: 350Wh ÷ 4h = 87.5W system needed

When to Consider Professional Help

Large installations like off-grid homes require precise calculations. Companies like EK SOLAR use satellite data and AI tools to optimize panel layouts – crucial for complex setups.
