Global warming is highlighting the need to urgently reduce our CO2 emissions. With FIT ending, and electricity prices continually increasing, installing rooftop PV to increase energy self- consumption is becoming more popular in Japan. We decided to install a SolarEdge system due to their advanced technology that maximizes our self-consumption and limits electricity grid export to zero. We are now able to save our electricity costs by about JPY150000 per month, which equals JPY1800000 a year. This means we will be able to pay back our investment within 6 years!

One reason Tsaruta Electric selected SolarEdge was for the export limitation option. Due to constant changes in energy consumption, when installing a PV system, utility regulations dictate that there should be no PV power export to the grid, in order to maintain grid stability. SolarEdge’s export limitation meter dynamically adjusts PV power production export when needed. It provides highly accurate readings for production and consumption monitoring, and supplies meter readings to the inverter.

In addition, SolarEdge’s module-level monitoring platform allows O&M providers to view and manage the system remotely and identify any defects or underperformance, such as bypass diode failures, potential induced degradation (PID), and micro cracks. This way, they can prepare the right course of action in advance, with fewer site visits, and less time spent on site.
