Optimizing solar asset performance

Soiling causes the greatest avoidable performance loss in PV systems. Without proper mitigation, an array can reach over 40% loss of its production output. The cost of washing a photovoltaic system can be between a third and a half of the total operating budget. With our toolset, your team can confidently manage soiling loss with real actionable data, telling you exactly when to clean. ARES INTELLIGENT SOILING LOSS MONITORING STATION ▸▸On-site soiling loss values ▸▸Clean irradiance measurement ▸▸PV spectral response ▸▸Automated self-cleaning ▸▸Self-powered and standalone ▸▸Easily deploy...

WEB PORTAL Fracsun’s custom software enables your team to access device data, view charts, and visualize optimal cleaning schedules. MEASUREMENT ARES generates a daily soiling loss value by comparing irradiance measurements of clean and soiled large-area reference cells. The Wash Extension hardware automatically washes the clean reference cell on a daily basis, eliminating the need for manual cleaning and measurement. ANALYSIS View and analyze ARES soiling station data through the web portal. Check charts, monitor device health, or download raw data for custom analysis. Easily import data...

SOLUTIONS FOR ALL STAGES OF THE SOLAR LIFECYCLE INTELLIGENT SOILING MANAGEMENT Soiling loss measurement and categorization can begin at any stage of a project’s lifecycle — at the early stages of development to improve bankability, or the sunset years of a PPA agreement to meet production guarantees. If you want to determine a new project’s viability, Fracsun can provide the country’s largest real-world soiling dataset. STAKEHOLDER BENEFITS ▸ Developers, Builders, and EPC Firms — Using local measurement data, improve confidence in production estimates, and forecast project performance with...
