What Are the Differences Between Residential Solar Design in India and the US From a Design Perspective?

As solar energy adoption continues to rise worldwide, understanding the differences in residential solar design across various countries is essential. India and the United States are two of the largest solar markets, yet their residential solar designs differ significantly due to variations in climate, government policies, energy needs, and building structures. Here’s a closer look at the key design differences between residential solar systems in India and the US. 1. Climate and Sunlight Availability India benefits from high solar irradiation, receiving 4–7 kWh per square meter per day, while the US experiences varying sunlight exposure depending on location. Southern US states like Arizona and California receive abundant sunlight, similar to India, whereas northern states receive comparatively less. This difference affects panel efficiency and placement strategies. In India, solar panel systems are designed to withstand extreme heat, while in the US, they must account for diverse ...
