Solar Power International 2015 Equipment Preview

SPI 2015 This September, the Anaheim Convention Center will once again host the Solar Power International conference and expo. Borrego Solar Systems installed a 2.372 MWdc array of Yingli Solar modules that covers 300,000 square feet of the convention center’s rooftops.

After a 4-year absence, the Solar Power International conference and expo will be back in California September 14–17 this year. According to the conference’s organizers, the Solar Energy Industries Association and the Solar Electric Power Association, close to 600 exhibitors will be showcasing their equipment and services at SPI 2015 in Anaheim, California.

This equipment preview article is intended to serve as an overview of some of the particularly interesting vendors that will be exhibiting in Anaheim. This list includes equipment that SolarPro’s editorial team noted at Intersolar North America in July, as well as products that will be on display or launched at SPI 2015. This vendor list is by no means comprehensive, but it will help solar professionals narrow their research on the expo floor, or online if you are not attending the event.

For those of you reading this article at the conference, I have included booth numbers for each of the companies profiled. If a product or service described here looks like it could provide a solution for you, I encourage you to walk on over to the company’s booth and learn more about it.

ABB Booth 4507

ABB’s acquisition of Power-One in 2013 vaulted the vendor into the number two position for inverter market share in the US. Since then, the company has continued to expand and refine one of the most extensive power conditioning product lines in the industry. For the US residential market, ABB offers three microinverter models, including the 300 W high-voltage MICRO-0.3HV-I-OUTD with a maximum open-circuit dc voltage specification of 79 Voc. Its residential line also features four UNO 600 Vdc string inverters with power outputs from 2 kW to 8.6 kW. For commercial rooftop and decentralized power plant applications, ABB’s 3-phase string inverter lineup includes the 1,000 Vdc–rated TRIO 20.0-TL and 27.6-TL models with rated power outputs of 20 kW and 27.6 kW, respectively. Its recently released ABB Rapid Shutdown system offers an NEC 2014–compliant solution for the rooftop market. The vender’s central inverter family includes the recently released 1,500 Vdc PVS980 models, which are available from 1,818 kVA up to 2,000 kVA for multi-megawatt PV power plants.

APsystems Booth 4327

With its three microinverter models, monitoring platform and expanding distribution base, APsystems (formerly APS America) is making inroads into the US module-level power electronics market. In its design approach, APS diverges somewhat from most other manufacturers of available microinverters, as a single unit processes the power from two, three or four modules, depending on the model, while performing MPP tracking of each module independently. APS’ 500 W YC500A integrates with two modules and can interconnect with 240 Vac and 208 Vac services. At 240 Vac, you can install a maximum of seven microinverters (14 modules) per 20 A branch circuit. For commercial 3-phase installations, APS offers two 900 W models, the YC1000-3-480 and YC1000-3-208 for 277/480 Vac or 208 Vac services, both of which support 3- or 4-module configurations per unit. While the YC500A model uses power-line communication, the YC1000 models feature wireless ZigBee communication. APsystems rounds out its microinverter systems with the Energy Communication Unit (ECU) gateway and Energy Monitoring and Analysis (EMA) software, as well as array cabling systems.
