Panama's tropical climate and abundant sunshine make it ideal for solar energy solutions. But how many watts of solar lights do you actually need here? This guide breaks down key factors like location, usage, and system design to help you choose the right solar lighting setup—whether for homes, businesses, or public projects.
Why Solar Lighting Works in Panama
With over 2,500 annual sunlight hours, Panama ranks among the top countries for solar energy potential. Solar lights here aren't just eco-friendly—they're cost-effective. Let's explore how to maximize this resource.
Key Factors Affecting Solar Light Wattage
- Daily Usage: A 10W light used 8 hours/day needs twice the battery capacity of one used 4 hours.
- Weather Patterns: Rainy seasons require 20-30% extra battery backup.
- Light Purpose: Security lights (15-30W) need more power than garden lights (5-10W).
- Panel Efficiency: Monocrystalline panels (18-22% efficiency) outperform polycrystalline in cloudy conditions.
"In Panama City, a 20W solar street light can illuminate 15 meters of roadway for 12 hours—perfect for residential areas." – EK SOLAR Case Study
Solar Wattage Recommendations by Application
| Application | Recommended Wattage | Daily Runtime |
|---|---|---|
| Residential Garden | 5-10W | 6-8 hours |
| Parking Lot | 30-50W | 10-12 hours |
| Highway Lighting | 80-120W | All night |
Real-World Example: Bocas del Toro Project
EK SOLAR's 2023 installation for a beach resort used:
- 40 × 15W pathway lights
- 12 × 60W floodlights
- Total system capacity: 1.32kW
This setup reduced the resort's energy costs by 35% in the first year.
5 Steps to Calculate Your Solar Needs
- List all lights and their wattages
- Calculate total daily consumption (Watt-hours)
- Add 25% buffer for Panama's microclimates
- Choose battery capacity (e.g., 100Ah battery = 1,200Wh)
- Size solar panels: Daily Wh / 5 sun hours × 1.3
Pro Tip: For Panama's 8.5°N latitude, tilt panels at 10-15° for optimal year-round performance.
Why Choose Professional Solar Solutions?
