Green Builder Innovation of the Year Awards 2021: Follow the Sun

This year’s greenest ideas bring us closer to harnessing the true potential of solar energy.

Samantha Carlin is co-author of this article.

It’s time again to honor an elite group of manufacturers and products that are making real progress in reducing the impact of construction upon our natural environment. They range from super-efficient solar energy management and heating equipment, to one-of-a-kind recycling projects and an indoor greenhouse. 

Products like these—along with help from a new, forward-thinking administration — will continue to steer us toward more sustainable lifestyles. 

Here’s a look at this year’s winners.

Solar Panels

Eagle TR G4 Solar Panel
Manufacturer: JinkoSolar

66-and-78-TR-V3-webJinkoSolar’s new Eagle TR G4 photovoltaic panel follows in the successful footsteps of its predecessors in the Eagle line but hosts a slew of new improvements. One of the most notable qualities of the panel is its Tiling Ribbon technology, which eliminates cell gaps— allowing the panel to have a higher efficiency, while reducing the size of its carbon footprint. 

Unlike its predecessor the Eagle G3, the TR G4 panel was specifically designed to be roof mounted. The unit’s smaller footprint decreases the amount of mounting and cabling materials necessary, saving time and money. 

The Eagle is durable, hosting the same back sheet as its predecessors. This makes it a good choice for structures in varied environments that may experience harsh weather, such as hail and extreme winds. The panel has an efficiency higher than 20.7 percent, with a maximum power output of 400W, packing a punch for its small footprint.

Because it uses a half-cell design, the panel can generate electricity even when partially shaded. The panel comes in the Eagle 66TR G4 and Eagle 78TR G4 sizes, as well as the Eagle 78TR G4b bifacial model with a 5 percent to 30 percent backside energy gain.

JinkoSolar’s latest evolution of its Eagle photovoltaic line offers all the effectiveness of its predecessors, but it’s also easy to mount on a roof or adjust the panel’s orientation to the sun.


NeON R ACe Solar Panel
Manufacturer: LG Electronics

LG Installer on Roof with ACe-webLG Electronics’ newest solar panel, the NeON R ACe, pushes the solar industry forward with new levels of convenience, both in installation and use. One of the panel’s most impressive features is its ability to house a direct current (DC) to alternating current (AC) 320W inverter right on the back of the panel. This makes the panel more convenient when installed and saves money for customers since they don’t have to buy a separate inverter. 

To improve convenience even further, the NeON R ACe panel plugs into a 240V circuit breaker and has only one cable accessory, drastically simplifying installation. This panel is also guaranteed to produce 90.8 percent of its labeled power in its 25th year. The NeON R ACe panel has a high efficiency of 21.7 percent, with a maximum power output of 380W, making it convenient and powerful. 

The panel has a high standard of performance in hot and cold conditions with a temperature coefficient of minus 0.3 percent/degrees Celsius.


Panasonic HIT+ N340 Solar Panel
Manufacturer: Panasonic Life Solutions

Panasonic N340 WBS 4-webEquipping a home with Panasonic HIT+ N340 solar panels brings further benefits beyond the increase in home value, attractiveness to buyers, and decreased energy costs of most solar panels on the market. The new benefits include efficiency, performance, dependability, and durability.

The HIT+ N340 Solar Panel delivers an advanced renewable energy source to power any home while issuing zero emissions. The high-efficiency photovoltaics feature a 20.3 module efficiency rating and 340 watts per panel. 

The N340 also delivers a zero emissions capability, being made of n-type crystalline cells combined with amorphous layers. In terms of extreme heat performance, the panels have a temperature coefficient of minus 0.258 percent/degrees Celsius. This technology decreases the annual degradation to 0.26 percent, compared to 0.70 percent in conventional panels, guaranteeing more power for the long haul.

With a smaller footprint and increased strength and durability, the HIT+ N340 Solar Panel allows for building flexibility and supports projects with higher voltage needs. The water drainage system helps to direct rain and snow off of the panel surface, reducing water stains and soiling, allowing more sunlight absorption, and ultimately increasing the lifespan of the panel.

By the numbers. Panasonic’s HIT+ N340 solar panels give homeowners an easy way to work toward having a house that is emissions-free.


Decks/Decking Related

MoistureShield Elevate Capped Composite Decking
Manufacturer: MoistureShield

LC Elevate Alpine Gray-webMoistureShield redefines decks entirely with its Elevate capped composite decking, which is among the most durable decking materials on the market, and 95 percent of which is made of recycled content. 

The solid core of MoistureShield’s composite decking is made from wood fibers, but to make it incredibly durable and water resistant, each wood fiber is encapsulated in a plastic barrier. This revolutionary design makes the decking so water resistant it can be used underwater. 

No exposed wood also means that there is no food source for insects, protecting the decking against typical damage from pests. With weathering and insect damage covered, this decking has no rotting or warping. This makes the decking much longer-lasting, and it even has a 50-year transferable structural warranty. 

On top of its durability, the deck is also affordable and sustainable, being made of recycled plastics and wood. This decking comes in a wide array of colors and finishes to perfectly match or complement an outdoor living space. Elevate is also slip-resistant and reduces heat by up to 35 percent, making the living space more comfortable and safer. 


AZEK Full-Circle PVC Recycling Program
Manufacturer: The AZEK Company

AZEK Beauty Timbertech-webTraditionally, when a piece of decking is trimmed off or siding is cut to fit, the scraps are thrown away. Now, The AZEK Company is changing all of that with its Full Circle PVC Recycling Program. Using an innovative product technology, an expansive network of professionals and its vertically integrated recycling capabilities, the company collects scraps directly from construction and job sites, and reprocess them into brand new decking, siding, cladding and trim. 

This on-the-ground program not only recycles more than 2.5 million pounds of PVC waste per year that would otherwise be disposed of in landfills, but also reduces contractors’ overhead waste disposal costs. More than 60 million PVC pounds are processed annually by AZEK partner Return Polymers.

And the environment isn’t the only one who benefits. The program makes it easier for contractors to advertise themselves as green builders, attract new clients, save money and reduce their environmental impact on the planet.

AZEK’s Full Circle PVC Recycling Program turns discarded decking and siding materials into born-again decking, siding, cladding and trim.
