We asked a group of solar experts

For the sake of information gathering, we have made a poll in one of the most active Facebook Group for solar experts called Quality Solar. They were asked with the question: “What are your top 10 string inverters for 10kWac installation?”.

A big thanks to all the people in this community who voted and shared their thoughts, so here is the result of the poll as seen below.

Conclusion

The quest for improving solar PV inverter quality is a never-ending journey. As the global demand for solar energy increases, it is essential that the overall performance of the solar PV devices also get better.

For solar string inverters, the competition for increasing maximum efficiency, better build quality, cost-effectiveness, and more safety features will bring a brighter future to the renewable energy industry, particularly the solar PV.
