Green Power on a Green Roof


Blue Frog microinverters and iTek modules are key features of a forward-thinking green roof in Seattle’s Meridian neighborhood.

The 3.36kW array by installer Multifacet Group of Bellevue includes Blue Frog/APsystems YC500-MIW microinverters and iTek 280W modules.

The rooftop terrace and garden on this custom 3,800 sf. home features Etera’s lush Sedum Tile all-seasons mix.

Homebuilder is Green Canopy Homes of Seattle.

Nichols joins APsystems as VP Sales, USA


apsystems-andrew-nicolsSolar industry veteran Andrew Nichols has joined APsystems as Senior Vice President of Sales, USA.

Andrew comes to APsystems with over 30 years in high technology and alternative energy sales. He most recently served as Vice President of Worldwide Sales for SolarBridge Technologies through its successful acquisition by SunPower Corporation.

“APsystems is the emergent front-runner in solar microinverter technology, and I’m honored to join their team,” Nichols said. “Their commitment to innovation in module-level electronics is really showing the way forward in this fast-growing segment.”

Blue Frog/APsystems microinverters are LCOE champs


Levelized Cost of Energy – the total cost of a PV system’s installation and maintenance over its lifetime, divided by the amount of power produced – is the industry standard for measuring a PV system’s value.

APsystems-microinverterIndividual components like Blue Frog/APsystems microinverters are key to the formula.

In its new story “LCOE Heroes: How inverters drive down PV levelized cost of energy,” Solar Builder magazine considers how the proprietary APsystems chip-based design means better long-term value for installers and end buyers.

It all starts with the Field Programmable Gate Array chip, which does so much of the microinverter’s work that each APsystems unit can be built with about 30 percent fewer discrete components than other brands. That means savings at the supply and manufacturing level that cascade into real savings for customers.

FEATURED INSTALL: YC500 ground mount array, Sunergy Systems

Greg Williams of Sunergy Systems is committed to renewable energy, even driving a 2001 Corbin Sparrow that’s been retrofitted with lithium batteries from Manzanita Micro of Kingston, WA
How better to juice up the car than with other certified Made In Washington solar products from Blue Frog/APsystems and itek Energy?

Sunergy’s senior solar design consultant and Kitsap County and commercial representative, Greg recently completed a ground-mount installation in his own backyard. The array features twelve 290-watt Itek modules and six Blue Frog/APsystems YC500 inverters, with an APsystems Energy Communication Unit and EMA monitoring.

Because of tree shading, Greg’s site was measured at 77 percent annual solar access – so the superior efficiency of Blue Frog/APsystems microinverters (compared to a conventional string system) was key to the design. The powerful array is calculated to offset about 34 percent of the electrical use in Greg’s 3,600 square-foot home/office, complementing another solar array already in place.

“Because of my beautiful cedar trees, this was a perfect application for the efficiency and reliability of the YC500 microinverters,” Greg says.

Sunergy Systems, a leading employee-owned Solar Design/Build Solar Installation firm has completed more than 1,000 installations to date.

5 Reasons a String Inverter Won’t Cut It.

Microinverters or string? PV system designers fall into two camps, some favoring big inverters and others moving toward the powerful little boxes that meet each module where the real action is: on the roof.

Knowing the limitations of string inverters may tell you just why the Module Level Power Electronics segment – including Blue Frog/APsystems microinverters – is on the rise.


Not made in the shade.

A PV array only works as well as the lowest-performing module. That means intermittent shading from trees, flagpoles – even fallen leaves – can cripple a string of modules as even minor shadows pass across the array throughout the day.

By offering independent, module-level inversion, a Blue Frog/APsystems microinverter installation can outperform a conventional string array by up 20 percent. You’ll get the most out of every module, every hour of the day.

Want to add modules? Too bad.

A string inverter that’s right-sized for an array today may be too small if you want to add more modules tomorrow. That means buying a bigger inverter, too. Ouch.

Blue Frog/APsystems microinverters are the forward-thinking choice, letting you add on to your array at any time, easily and cost effectively.


Better value in the long run.

Startup costs of a string system might be lower on a per-watt basis, but what you save up front, you’ll lose over time in lower performance.

The key metric of Levelized Cost of Energy – that is, system cost measured over its lifetime – favors microinverters. The microinverters start generating power at lower light levels than string inverters, so the power curve raises and peaks earlier in the day and extends further into the afternoon and evening.

Thanks to module-level inversion at these lower light levels, Blue Frog/APsystems microinverters enjoy a superior output and higher rate of energy production.


Don’t forget safety.

Every module in a string adds more to the DC current flowing across the rooftop – quite a volt load by the time it reaches a inverter, up to 1,000 volts DC. Not very safe for installers or emergency responders who may have to cross the roof.

Blue Frog/APsystems microinverters take the jolts out of the volts. Module-level inversion means only low-voltage DC in each circuit, keeping you safe over the life of the system.


Module-level power is the future.

String inverters still have their niche, but module-level power inversion is tomorrow’s technology today. A leading analytics firm recently noted that sales of microinverters and related products should top 2 gigwatts by year’s end, and predicts microinverters’ share of the larger MLPE market could triple by 2018. That’s a product with a bright future. That’s a product with a bright future.
