Globally, over 300 GW of large-scale PV solar power plants have been installed since 2008 - with over 40 GW in the U.S. alone. The performance of these power plants naturally decreases over time as PV modules degrade and as inverters reach their end-of-life and fail. As a result, some systems become a liability while others perform within contractual obligations, though still not at full potential. Consequently, system owners and operators often look for inexpensive ways to repower their existing and aging systems.
Ampt and Rosendin Electric are using string optimizers to improve legacy system performance while achieving a rapid and high ROI. Ampt String Optimizers are DC/DC converters that use patented voltage and current limits as well as maximum power point tracking (MPPT) on each string of PV modules to improve the production of existing systems. Ampt optimizers are deployed within the existing DC infrastructure - as is - which allows for rapid deployment without rewiring or trenching for a significant cost savings.
In this webinar, you will learn how Ampt and Rosendin Electric’s Repowering Solution:
- Opens new opportunities to increase system revenue
- Recovers degradation related energy losses
- Avoids costly rewiring and trenching when replacing inverters
- Enables inverter upgrades now or in the future using the latest inverters at a reduced cost
- Allows the use of 1000-volt inverters at full rated output power in 600-volt systems or 1500-volt inverters in 1000-volt systems
- Allows PV arrays to be expanded to DC/AC ratios of 2:1 or more without overloading the existing inverters, combiners, or cables
- Leverages Rosendin Electric’s expertise and nation-wide service organization
- Includes an initial site evaluation and degradation analysis, electrical planning, installation, and recommissioning support to ensure success
A case study will also be provided.
You’re invited to join Ampt and Rosendin on November 16th, 2017 as we discuss how string-level optimization improves the output and ROI of PV systems.
