The Seaward Solar Survey 100 is a high quality irradiance meter designed specifically for solar surveys and solar site assessments. It includes a tilt meter, digital compass and dual channel temperature measurement for ambient and PV panel temperature, making it effectively a “5 in 1” meter, eliminating the need to carry 4 other pieces of equipment around during surveys.

The Solar Survey 100 uses a photovoltaic reference cell over the conventional photo-diode, to generate more accurate solar irradiance readings in either Wm² or BTU/h/ft². The built-in digital compass, digital inclinometer and dual channel thermometer mean that surveyors can measure roof pitch and orientation, ambient temperature and PV module temperature, in order to gain all necessary information on potential solar sites.

The Seaward Solar 100 Irradiance Meter can be used on both solar photovoltaic and solar thermal installations, so the most suitable location and optimum angle of inclination can be determined, so that maximum efficiency can be achieved from solar energy.

This model features an automatic power-off after 2 minutes, to conserve battery life. It is powered simply by 2 x AA batteries, and the full battery life can last up to 20,000 readings. The Solar Survey 100 measures solar irradiance in compliance with IEC 62446, and is supplied with a durable carry case as standard.
