Paper Abstract

We describe optical test methods for indoor and outdoor assessment of concentrating photovoltaic (CPV) and concentrating solar power (CSP) plants and modules. Testing may be done in active mode, where the cell is driven in forward-bias mode, and passive mode, where the system or parts of it are illuminated do measure performance and detect errors. An update on the design and development of the concentrating solar simulator is given. A camera may be used to verify optical alignment and tracking sensitivity of the concentrator system. Indoor testing is required for quality assurance. It is a condition for performance guarantees and performance-based pricing.
