Summary: Rooftop solar panels in Paraguay face unique challenges due to high temperatures. This article explains how heat impacts photovoltaic (PV) performance, shares local case studies, and provides actionable cooling strategies for homeowners and businesses.

Why Paraguayan Rooftops Are Ideal – Yet Challenging – for Solar Panels

Paraguay's photovoltaic panel installations have grown by 42% since 2020, driven by abundant sunshine averaging 300 days annually. But here's the catch: those same panels that thrive on sunlight can lose efficiency when roof temperatures exceed 45°C – a common occurrence in Asunción summers.

The Science Behind Solar Panel Heating

Three main factors cause photovoltaic panels on Paraguayan roofs to heat up:

• Tropical UV Intensity: Paraguay's UV index regularly hits 11+ (extreme level)
• Roof Material Matters: Zinc-aluminum roofs reach 65°C vs. clay tiles' 58°C
• Airflow Restrictions: 70% of residential installations lack proper ventilation gaps
