Monitoring photovoltaic panel string welding machine accessories

Which solar cells can be soldered with ecoprogetti Stringer machines?

Ecoprogetti’s stringer machines are designed to work with all the solar cells available on the market (from 166mm to 210 mm), full and half cut. The best soldering output with minimal stress given to the solar cells, realizing high-quality photovoltaic modules with minimized breakages during the transformation process.

How effective is string monitoring in detecting solar panel failures?

Regarding the monitoring at a string, a decrease in the power generation amount due to a solar panel failure, can be detected quickly. The unit can be introduced inexpen-sively, when compared with the system required for moni-toring at a panel. Consequently, string monitoring is highly effective in the detection of solar panel failures.

How many solar panels are in a string monitoring unit?

Each string consists of about 10–20 solar panels connected in series. Furthermore, the string monitoring unit can be retrofitted easily. This paper reports the characteristics and specifica-tions of the string monitoring unit, and the results of the analysis of power generation data obtained by the system. 2.

Why do solar power plants need a string monitoring unit?

While an increasing number of megawatt solar power plants have been constructed, some of them have already been facing problems with degradation in power output due to initial failures, aging solar panels, or external factors. We have developed a string monitoring unit that uses the power line communication (PLC) technology.

What is a solar Stringer machine?

The solar stringer machine is used to solder solar cells together with the use of bus bars into forming strings. This category of assembly equipment is one of the most sensitive since the soldering of the connections is what enables the photovoltaic module to transmit electricity.

What is a string monitoring unit?

We have developed a string monitoring unit that uses the power line communication (PLC) technology. These units monitor individual strings of hundreds of thousands of solar panels in real time without the need for wiring additional cables.
