Design Your Solar System Smartly & Accurately
The Challenge
Solar sizing shouldn't be guesswork
Manual calculations lead to undersized or overpriced systems.
Designing an off-grid or hybrid solar system requires balancing irradiance data, temperature derating, battery cycles, and load profiles. Sizing systems without accurate climate data often leads to battery failures and wasted investments.
Inaccurate sizing leading to early battery degradation
Difficulty fetching local PVGIS and irradiance data
Lack of standardized quotation comparison tools
