Commercial & Industrial PV Adopts 1500V High-Power Solutions. What Do the Cost Savings Look Like?

For a long time, distributed solar pv plants have been an important part of the clean energy mix. Most solar projects are 1100V and 1000V, but with the adjustment of policies across the globe, grid parity, cost reduction and efficiency increase have become the primary considerations of developers of distributed power stations. Under this new green power ecology, the 1500V system is gradually becoming the mainstream in large-scale projects such as ground power stations. With its high-voltage array, low line loss, high efficiency, high power density, and easy installation and maintenance a 1500V system is a logical choice.

So, can C&I rooftop power projects that occupy an important position in distributed power stations also use 1500V systems? In this seminar, we will share with you the application challenges of the 1500V system in C&I projects with an actual green power project on the grid at a competitive price.

Project Overview

In order to actively respond to the national energy-saving and emission-reduction strategy and reduce the company’s electricity expenses, Hai Dexin Automotive Appliances, in China, chose Solis for a  PV solar power system on the company’s production site and office building roofs.

Through the preliminary survey of the site by the designers, it was determined that the overall capacity could reach 1.5MW. According to the comprehensive analysis of the project capacity and the company’s current power supply and consumption, the Power Supply Bureau recommended that the solar installation adopt a 10kV high-voltage grid-connected system, and classify it as a self-generated and self-use surplus electricity project, and issue a project grid connection report.

Plan & Design Comparison

The project is high-voltage grid-connected, and the roof environment is good, the space is large, and the orientation is single. The project capacity is expected to reach 1.5 MW. In summary, all the conditions are suitable for Solis high-power inverter solutions. Therefore, for the successful implementation of the project, the Solis design team has given two sets of solutions.
