US-based energy equipment supplier Ampt will deploy its DC optimisers in a 33MW photovoltaic (PV) system for power company Canadian Solar.
The Canadian firm will be using Ampt's direct current (DC) String Optimisers in one of the largest deployments in the world.
Canadian Solar's general manager Ken Rowbotham said: “Our initial work with Ampt surpassed expectations and laid the groundwork for the 33MW utility-scale installation.
“We chose Ampt for its clear technology advantages, which support our broader commitment to being the industry-leading provider of clean solar energy across the globe.”
Following the successful demonstration, Canadian Solar selected Ampt's String Optimiser as it consistently outperformed other designs while costing less. In comparison to other products, it delivered superior value and maximum power point tracking (MPPT) to mitigate losses due to mismatch. This allows the inverter to operate at both high and low-input voltage ranges to improve inverter performance.
Ampt's CEO Levent Gun said: “While the PV market is on track to experience significant growth, the need to lower system costs is paramount.
“Some large-scale solar developers are considering changing from 1,000v to 1,500v DC systems, while others are choosing to deploy String Optimisers.
“Both of these approaches reduce cost by eliminating electrical balance of system (BOS) components, but only Ampt increases MPPT resolution to improve lifetime system performance.
“As the industry works through the challenges of 1,500v component costs and availability, Ampt String Optimizers provide an immediate advantage using 1,000v components.”
According to research from Global Market Insights, DC power optimisers will continue to see a quick growth in the solar market.
