3-phase Array at Pennsylania’s Cleaveland/Price plant

When your customers are electrical utilities, you tend to think of power on a grand scale.

So no surprise the new solar array at Pennsylvania’s Cleaveland/Price switch manufacturing plant will take its place as one of the larger solar arrays on the local grid: 673kW.

Cleaveland/Price engineers designed the 2,245-module array themselves, and chose APsystems YC1000 microinverters were chosen for their true 3-phase power handling and multi-module design. Each unit will handle three modules, simplifying the installation.

The APsystems units also offer low-voltage startup, an advantage over string systems and boosting solar harvest.

“It only takes 22V to start up the microinverter to produce AC, so it is ideal for Pittsburgh’s cloudy and low-light days,” says Steve Cleaveland, principal in Cleaveland/Price.

Anacortes Residence, Fire Mountain Solar

An elongated floor plan, with two distinct solar roof spaces separated by a long distance, was no impediment to a great PV system at this new Anacortes home.

The system was wired in and installed during home construction, and Blue Frog YC500A-MIW microinverters allow precise performance monitoring of the separate arrays at each end of the long structure.

“Pre-wiring for the job was a breeze as we could run Romex (cable) through the open studs up to the roof J-Box,” says Tim Nelson of Fire Mountain Solar. “No EMT conduit was needed, because we ran AC up instead of DC down!”

Edmonds Waterfront Home

The GSG residential installation by Forecast Solar was part of a massive remodel of an old waterfront home in Edmonds.

The new roof structure incorporated an offset gable that allowed three-fourths of the roof to face south. The owner cashed out an IRA to fund the project, and because it used Washington-made solar products, the financial benefits from his new PV system far outpaced his returns from the old IRA.

With only 82 percent solar exposure and challenging, intermittent shadows during peak hours, the project would not have been financially feasible without Blue Frog/APsystems microinverters.
The project recently completed its first-year production cycle with 6,838 kWh, over 1,000 kWh hours more than expected. The owners are elated.

Inland Power & Light Community Solar

This 30 kW ground-mount array in Spokane, Wash., is the first significant venture into solar for Inland Power & Light, a member-owned utility serving 39,000 residential and commercial customers in 13 counties in eastern Washington and northern Idaho.

The system was funded by utility members who bought shares through a lottery sponsored by the utility. Shareholders now receive the benefit of net metering, that is, the positive difference between their own power consumption and what their portion of the community solar system provides. They will also see a pro rata rebate from Inland Power for each kilowatt hour of power produced.

Opportunity for such “community solar” projects was created by the Washington state Legislature, to encourage utilities and local governments to add clean energy arrays to their own production capacity.

“When a utility installs a system, it helps promote solar for their customers,” says John Harley, vice president of Brimma Solar, which installed the Inland Power array. “Customers with solar, or thinking about installing solar, feel comfort when they know their utility supports solar.”

The project is also a showcase for Washington’s solar manufacturing industry. The installation includes PV modules by itek Energy of Bellingham, APsystems YC500A-MIW microinverters by Blue Frog Solar of Poulsbo, and racking by SunModo of Vancouver.

Northernmost grid-tied solar Install, Canada

APsystems 3-phase microinverters now power the northernmost grid-tied solar installation in the Americas – the Community Hall at Pond Inlet, Nunavut, latitude 72N.

Vancouver Renewable Energy (VREC) powered up the 590kW system in Canada’s newest and northernmost province in September.

The 9.3kW community system features 32 SolarWorld 290-watt mono-crystalline modules and eight APsystems YC1000 true 3-phase microinverters.

In just three weeks the PV system had produced 590kWh of power, saving hundreds of dollars on the municipal power bill for the remote, 1,500-person hamlet. The community otherwise relies on a diesel “tank farm” and generator plant for its power needs – an expensive proposition now helped by clean, renewable solar and APsystems microinverter technology.

The new array will be paired with a mural celebrating light, both from the sun and from qulliqs, traditional Inuit lamps that use animal fat for fuel, according to the Vancouver Renewable Energy blog.

Sedro-Woolley Ground-Mount Array

The team at Banner Power Solutions faced several challenges while planning, designing and installing this 9.54 kW residential system in Sedro-Woolley, WA. Due to lack of desirable roof space and moderate shading issues, a ground-mount system was chosen to maximize array size and sun harvest potential. To accommodate an 8 percent grade, the 50-foot array was split in two, and the hillside slightly terraced to accommodate three dozen PV modules. Blue Frog/APsystems YC500A-MIW microinverters were selected for the easy monitoring system and 25-year warranty.

La Conner Residence

When designing a PV system for this stylish contemporary home in La Conner, Skagit County, the team from Whidbey Sun & Wind chose Blue Frog microinverters and itek PV panels.

A total of 18 Itek 260-watt modules and nine APsystems YC500A-MIW inverters were used in the 4.68 kW, tilt-rack system. The installation was completed in March.

“We chose itek and APsystems/Blue Frog equipment to take full advantage of the Made-In-Washington financial benefits,” says Mark Anderson, project manager and NABCEP Certified PV Installation Professional. “The APsystems inverters allowed us to avoid both string sizing and slight shading issues.”

Anderson’s team went through several designs before opting not to do a ballasted system, choosing instead to do a fully attached installation. A local company re-roofed the original torch-down roof with a TPO membrane and took care of flashing around the system attachment posts. Racking is by Snap-N-Rack.

“We expect this PV system to offset nearly all of the customers’ electrical needs,” Anderson says.

Founded in 2000, Whidbey Sun & Wind offers a full slate of renewable energy products and services including solar electric, solar water heating, wind power and micro-hydro.

Ellensburg PV Array

When homeowners wanted a PV system for this Ellensburg, Wash., ranch-style house, designers from Central Wind & Solar faced an unusual challenge.

The array had to mounted so as to leave an egress aisle between the PV modules and the upstairs bedroom windows, so residents would be able to exit across the roof in an emergency. Because the modules would be farther down on the roof, they would be more susceptible to snow buildup – the Eastern Washington equivalent of partial shading – on the roof above them during the winter months.

This challenge made the system a good candidate for APsystems YC500A-MIW microinverters, which provide independent output from each module to optimize the entire system.
