Options allow performance and efficiency

The system must be measured under all operating conditions. A compass and an adjustable level indicator are supplied to allow on-site adjustment of the panel.

Thermocouple switches

An instrumentation and water circulating console is attached to the panel under test via flexible hoses and this displays the circulating water flow, flow and return temperatures, ambient temperature and incident solar radiation.

The operating temperature of the system is adjusted by a flow of cooling water and this allows investigation of performance over a range of operating conditions.

The incident solar energy is measured using a solarimeter and this together with the other measured parameters allows the performance and efficiency of the system to be measured under all operating conditions. A compass and adjustable level indicator are supplied to allow adjustment of the panel on site.
