Temperature Probe for Photovoltaics – Temmeter

Last update

Temmeter is a highly resistant temperature Probe for photovoltaic modules (solar panels), based on a PT100 temperature sensor. It has strong adhesive fixing for quick and easy installation.

Adhesive fixing makes it more economical than Temmeter PRO, without sacrificing efficiency.

Temmeter is an easy-to-install PT100 thermal sensor that does not require a mounting system, as it has a powerful adhesive surface.

The white non-hygroscopic plastic casing is resistant up to 130°C; shows neutral behavior in temperature measurement even in the presence of direct radiation on the sensor.

Note: Solar modules exposed to high temperature produces less power than same module at 25°C. Correct Performance Ratio (P/R) calculation requires the correct formula. In Southern Europe PV module temperatures can reach 85°C during Summer; in those cases the loss of output power are lower of around 25%!

Soluzione Solare temperature probes are designed for outdoor use and quick response to temperature variations (from several milliseconds to a few seconds) in order to ensure precise Performance Ratio calculations.

Key features

  • Fast speed of response to temperature variation (under 5 seconds, high thermal transmittance).
  • Strong adhesion even to surfaces with low surface tension such as Tedlar.
  • Measurement precision is above the required standards (PT100 class A sensor).
  • Protected cable.

Note: please remember that for accurate temperature measurements of your solar panels, ensure your are measuring the temperature of a representative module of the plant.
