Seaward Solar Survey 100 Irradiance Meter

The Seaward Solar Survey 100 is ideal for people doing a Solar Survey or solar site assessment. Not only is this a high quality irradiance meter but it includes a digital compass, tilt meter and dual channel temperature measurement for ambient and PV panel temperature. The low cost Survey 100, 5 in 1 meter means you don't have to carry around four separate solar surveying instruments. If you need a 6 in 1 meter with datalogging as well take a look at the Seaward Solar Survey 200.

The Solar Survey 100 uses a photovoltaic reference cell, rather than a photo-diode, to more accurately measure solar irradiance in either Wm² or BTU/h/ft². In addition this solar surveying tool also has a built-in digital compass, digital inclinometer and dual channel thermometer. These extended functions enable solar surveyors to measure roof orientation, roof pitch, ambient temperature and PV module temperature for a fully comprehensive overview of potential solar sites.

The Seaward Solar Irradiance Meter is suitable for use on both solar photovoltaic and solar thermal installations, making it possible to identify the optimum location and best angle of inclination to achieve maximum efficiency from the sun’s energy.
