Seaward Solar Survey 100 Irradiance Meter

The Seaward Solar Survey 100 is a fantastic solar survey tool which offers all you need to carry out solar efficiency surveys by measuring irradiance as required by IEC 62446.

Suitable for both solar thermal and solar pv (solar photovoltaic) applications, the Seaward Solar Survey 100 is capable of measuring irradiance up to 1250Wm-2 or BTU/hr/ftf2. The unit operates as a solar cell – rather than using photo-diodes – giving highly accurate readings as a result.

Modular and ambient air temperatures can also be read at the same time, letting you work more efficiently. And, to cap it all, the Solar Survey 100 even allows you to freeze the screen using a hold function – which means you won’t have to rush when recording measurements, even in tricky locations.

A built-in tilt meter and digital compass allow precise measurement of roof inclination and orientation. Combining a host of useful features within a solid, handheld unit, the Seaward Solar Survey 100 is a valuable tool for any installer of solar pv or thermal systems.
