Customer Story

PV Diagnostics (Mumbai, India) specializes in onsite testing services, providing quality control and diagnostics for solar power plants across India. The MP-11 I-V Checker is a portable, all-in-one measurement solution designed to deliver accurate on-site I-V performance measurements of PV modules and arrays.

In 2017, needing a new instrument for on-site measurement, PV Diagnostics decided to launch a comparative study of I-V Curve Checkers. EKO Instruments’ M-11 was chosen to face-off against two competitors, both similar devices, but with some key differences.

Each device was assessed independently, on-site, and in real working conditions. Features ranging from ‘accuracy’, through ‘robustness’, and ‘ergonomics’ were ranked from high to low. ‘Battery time’, ‘sensor range’, ‘sweep time’, and ‘wait time’ was also scored by the engineers testing each device.

The MP-11 scored high in each category. It was accurate; it was robust; it was fast and portable. It also had onboard memory, an in-built display, and supported integration with an external pyranometer; features not all shared by the competition.

“Three years ago, we had a tough choice to make. The volume of on-site tests that we conduct, plus the distances and geography we have to cover, we couldn’t afford to make a mistake” explained Pranav Maheshwari, an Engineer at PV Diagnostics. “Comparing different devices the way we did was a great way to establish beyond doubt that the MP-11 was the best option for us, and we haven’t been disappointed”.

Three years later and PV Diagnostics now operates seven MP-11 units, have measured more than 250k I-V curves, and describe the MP-11 as ‘the most effective device for on-site I-V curve measurement’ and ‘the easiest to use while conducting field measurements in large quantities’. 

The MP-11 is distributed in India by Meteoxperts Solutions (Delhi, India). Find out more about EKO I-V Measurement devices and request a quotation at eko-asia.com.
