If you're planning to install a solar panel system in India, one of the most important design choices you'll make is the orientation—which direction should your panels face? For most homes and businesses, the choice boils down to two options: East-facing or South-facing. Let's break down the difference—and what works best in Gujarat’s climate. 📍 South-Facing Solar Panels – The Optimal Choice ✅ Maximum Sunlight Exposure In India, the sun is mostly in the southern part of the sky throughout the day. South-facing panels get direct sunlight for the longest duration, especially from 9 AM to 4 PM. ✅ Higher Energy Output South-facing systems typically generate 10–25% more electricity compared to east- or west-facing systems. ✅ Best ROI for Residential & Commercial Use More energy = more savings = faster return on investment. Perfect for homes, shops, factories, and offices aiming to reduce grid dependence. 🌅 East-Facing Solar Panels – A Good Alternative in Some Cases ✅ Better for Morning Usage Patterns If your energy usage is heaviest in the morning (e.g., restaurants, bakeries, or homes with early routines), east-facing panels may align better with your demand. ✅ Site Constraints Not all rooftops allow perfect south-facing installation. If your roof orientation or space is limited, east-facing panels are still a viable and productive option. ✅ Slightly Lower Output – But Still Efficient You may see around 10–15% less output compared to a south-facing setup. But with proper panel tilt and a high-efficiency system, the gap can be minimized. 📐 What About Tilt Angle? Regardless of the direction, tilt angle matters a lot. In Gujarat, the ideal tilt is roughly 15° to 25°, depending on the roof type and seasonality. 🧠 Pro Tip from Reliable Solar At Reliable Solar, we always perform a site-specific shadow analysis and ROI projection before recommending a layout.
