[Rocklin, CA] In April 2016, SMA Technology acquired a 27% stake in module-level power electronics (MLPE) manufacturer Tigo Energy. SMA’s recently launched Power+ Solution leverages this partnership by combining its single-phase Sunny Boy-US inverters, available in six power classes ranging from 3 kWac to 7.7 kWac, with Tigo’s TS4-R platform. The Tigo TS4-R is a modular MLPE retrofit system that integrates up to four features into interchangeable covers that are compatible with the product’s standardized base. Available features include module-level monitoring, NEC 2014 rapid shutdown and NEC 2017 module-level shutdown-compliant functionality, optimization and a long-string functionality that increases allowable PV source-circuit lengths. A unique characteristic of the TS4-R system is that installers can selectively deploy MLPE to meet specific system requirements. For example, installers can equip two modules in close proximity to a rooftop chimney with optimization MLPE to minimize the impact of localized shading. This selective deployment option can be a streamlined, cost-effective approach to increasing PV system functionality and performance.

[Livermore, CA] Balance of system product developer SolarBOS has launched fused ac combiner and recombiner solutions for commercial, industrial and utility-scale PV plants. SolarBOS designed the products to facilitate the aggregation of the ac output for multiple-string inverters. Fuse-based combiners offer some distinct advantages over breaker-based products. Fused products can offer better performance at elevated temperatures, thereby reducing nuisance trips. Current-limiting fuses reduce arc flash energy by a factor of 5–10 and the level of PPE required during equipment servicing. Additionally, many string inverters include load-break–disconnecting means. This allows the use of non–load-break fuseholders to isolate inverters, which can result in significant cost savings.

[Hillsboro, OR] SolarWorld recently announced that it has doubled the workmanship warranty on its portfolio of solar modules to 20 years. The extended product warranty, which protects against defects attributable to production flaws, applies to all SolarWorld modules shipped after January 1, 2017. SolarWorld’s current module lineup includes its Sunmodule Bisun SW 290 Duo, a 290 W STC glass-on-glass bifacial module rated for 1,000 Vdc applications.

[Newark, NJ] Panasonic Eco Solutions North America has added three high-efficiency models to its HIT module lineup for residential applications. Panasonic’s hetero-junction type (HIT) cells are composed of monocrystalline and amorphous silicon layers. The amorphous silicon layers minimize electron recombination, which in turn minimizes power loss and increases overall module efficiency. The 96-cell N320K, N315K and N310K modules have a rated STC power output of 320 W, 315 W and 310 W, and module efficiencies of 19.1%, 18.8% and 18.5%, respectively. The highest-power module in the line has a maximum power voltage of 58.7 V and an open-circuit voltage of 70.5 V. The module’s black cells, backsheet and frame create a uniform appearance that blends with many residential rooftops. Panasonic backs the N320K, N315K and N310K modules with a 25-year linear power output and a 15-year workmanship warranty.

[Oakland, CA] PVComplete, a solar design software provider, has introduced PVCAD. Powered by Autodesk technology, PVCAD enables solar designers and engineers to create comprehensive project designs for ground-mounted, rooftop and carport PV installations. PVCAD leverages the benefits of AutoCAD, plus PVComplete’s layout, energy modeling, electrical diagrams and equipment library. The software allows users to efficiently compare and contrast array layout iterations. The designer can quantify each design choice through a built-in energy production model and estimate project costs through the generation of an automatic bill of materials. In addition, PVCAD performs the electrical calculations necessary for PV project design and generates single-line drawings.

[Lawrence, MA] Yaskawa–Solectria Solar has announced the introduction of its Commercial Rapid Shutdown Combiner for 3-phase string inverter systems. The combiner meets the requirements of Article 690.12 of the 2014 and 2017 NEC, which requires the ability to de-energize dc conductors located outside the array boundary upon loss of ac power to the service. The Commercial Rapid Shutdown Combiner is compatible with Yaskawa’s lineup of seven 3-phase inverter models with power classes ranging from 14 kWac to 60 kWac. The combiner allows operation of one- or two-MPPT zone configurations with up to five strings per MPPT zone.

[San Francisco] Spruce is expanding its national network of solar integrators, building contractors and other channel partners to provide consumer financing for residential PV systems and home efficiency improvements. The firm was founded in 2015 with the merger of Clean Power Finance and Kilowatt Financial. Spruce offers white-label products that include solar leases and power purchase agreements as well as solar loans. It currently offers its Spruce Solar Loan product in 25 states and makes it available for single-family residences as well as townhomes, condos and duplexes. The online SpruceFlow portal is designed for mobile devices and allows outside sales teams to generate a proposal, run e-credit and get an e-signature from the homeowner on-site. To further support residential solar integrators, Spruce offers its SourceDirect equipment-purchasing program, which provides integrators with an alternative to carrying the up-front equipment cost for financed projects.

[Fort Collins, CO] In 2012, REFUsol brought one of the early UL-listed 3-phase string inverter product lines to the US market. US-based Advanced Energy acquired REFUsol’s US product line in 2013, before exiting the inverter market altogether in 2015. REFUsol is currently a REFU Elektronik GmbH division under parent company German Prettl Group. Prettl Energy North America operates a US sales office in Fort Collins, Colorado. Two REFUsol 3-phase inverter models are available in the US, the 24 kW 24K-UL-USA and the 48 kW 48K-UL-USA.

[Hayward, CA] Designed and certified for composition shingle roofs, IronRidge’s FlashFoot2 array mounting and flashing system uses a stack of components to elevate the three-tier water seal an inch above the roof plane. The design eliminates life-limited materials, such as EPDM rubber, from the water-shedding plane of the flashing. In addition, FlashFoot2’s twist-on cap fully encapsulates the elevated water seal, obviating the need for a separate L-foot bracket. The product’s design eliminates any offset between the rail and lag bolt, resulting in a concentric load path that transfers forces directly to the lag bolt. As a result, the unit achieves an allowable uplift capacity of more than 1,000 pounds. IronRidge’s FlashFoot2 has passed the UL 441 Section 27 “Rain Test” and TAS 100-95 “Wind Driven Rain” test. It is electrically and structurally certified to UL 2703 and IBC 2016, respectively.
