        Major Tech MTPV33 | Solar Power Meter 1400 W/m²

        The Major Tech MTPV33 is a high-precision solar power meter designed for solar panel installers, researchers, and maintenance professionals. It measures photovoltaic irradiance from 50 to 1400 W/m² with ±5% accuracy, helping optimize solar panel efficiency. The large LCD screen displays real-time readings, while data hold and Min/Max memory functions make it easy to track performance over time.

        This meter also includes a built-in compass and inclination sensor to ensure precise panel alignment for maximum energy output. An integrated temperature sensor provides environmental readings to help assess site conditions. Compact and lightweight, the MTPV33 runs on four AA batteries, making it perfect for field use in solar energy assessments.
