What are the new solar panel designs and aesthetics? One of the most common criticisms of the solar panels available today is their appearance on a roof – many homeowners considering solar are looking for a product that will both generate energy and offer a stylish and aesthetic improvement for their property. In response, solar panel manufacturers are developing new solutions to give solar the makeover homeowners have been asking for.
Frameless solar panels A major factor in the critique of solar’s aesthetic is the solar panel frame, which many homeowners find to be the least attractive part of a PV panel. To so
SolarWorld, Canadian Solar, and Trina are producing frameless solar modules. The main hinderance for these aesthetic panels is the lack of suitable mounting equipment that can work without a frame. As a result, manufacturers are producing specialized mounting apparatus to match their frameless panels. One example of this is Lumos Solar, which offers the LSX Frameless Module as well as its own dynamic mounting solution.
Clear solar panels
Many frameless panel designs are entirely enclosed in one material, typically glass. Glass solar panels use the same silicon cell tchnology and materials of a standard panel, but rather than being mounted on an opaque backing material, the cells are sandwiched between two glass casings. In most scenarios, glass panels are bi-facial, but we will save that concept for later in the article.
Glass solar panels are an innovation in multiple ways because, in addition to being more visually attractive, glass panels are more durable than a typical silicon cell panel. These panels are known to be significantly more resistant to fire hazard and are also less prone to erosion. Prism Solar, DSM Advanced Surfaces, Topray Solar and Sunshine Solar are some of the leading solar glass manufacturers in the industry today. Though glass-on-glass panels are often integrated into a skylight or building window (as in the image below), they are not truly “building integrated photovoltaics” because they are attached to the building rather than incorporated into the building envelope.
Tesla solar tilesTesla’s new roof panels are a unique, distinct product and should be placed in their own category of panel innovation. The four PV shingle designs, announced at the end of October, offer a design promise entirely unique from any other product coming to the solar marke: they are unequivocally non-recognizable. The latest from Elon Musk allows homeowners to go solar without any noticeable difference on their roof. As demonstrated at Tesla’s launch event, these solar tiles are significantly more durable than the standard roof materials commonly used today. The solar roof product is designed to ble
d in with typical roof aesthetics and thus will come in the following product lines: Tuscan glass, slate glass, textured glass and smooth glass tiles.
Solar skin design Sistine Solar, a Boston-based design firm, is making big strides with the concept of rooftop solar panels with a customized look. The MIT startup has created a “solar skin” product that allows solar panels to have a distinguished look that c
New solar panel product improvements
ith well over 200,000 workers in the U.S. PV industry, it’s no surprise that new panel efficiencies and product improvements are announced practically every week. In some cases, it’s difficult to stay up to date on all of the developments in solar panel technlogy. In the past two years, the concept of “average solar efficiency” has risen from the 14-15 percent range up to 16-17 percent – a significant margin. In 2019, there are 60-cell solar panels that have comparable outputs to 72-cell panels. Efficiency is changing the affordability of solar and the residential market is set to reap the benefits.
One company to note is Panasonic, which is challenging the likes of SunPower with premium PV efficiencies (upwards of 20%) offered at mid-tier prices. A big reason for the success of this manufacturer and tech giant is their dynamic heterojunction panel product (HIT) that combines maximum efficiency and optimized temperature control to allow for top performance under extreme conditions of sunlight. And now for its next trick: Panasonic recently announced that it will manufacture the solar cells for Elon Musk’s illustrious solar roof. With aesthetic design, high efficiency and BIPV rising up as the next big trends in solar manufacturing, Panasonic is a company to keep an eye on. Other PV innovators have been LG and SolarWorld, which are both making major strides in the world of bi-facial panels, glass-on-glass, inverter integration and high capacity PV.
Double-sided solar panels Formally known as bi-facial solar panels, double-sided PV is a hot topic in solar and will continue to be an attractive product option for homeowners in 2019. Double-sided panels offer the value described in their name: they can harness sunlight through both surfaces of the panel. The simple premise is that double-sided panels can capture light as it reflects off of the roof or ground surface below the panel. Because the majority of roofs in the residential market are black, installers will typically paint a white border around the solar panel system before installation to maximize light reflection. In the case of ground mount solar, the light will naturally reflect off the ground (especially during winter, when the modules will benefit from a naturally white ground surface due to snowfall).
LG introduced its bifacial “Cello” technology in 2016 with the launch of the Neon2 panel, which boasts increased power output as well as an improved aesthetic thanks to its frameless apparatus and sleek black appearance. In tandem, manufacturer behemoth SolarWorld unveiled its Sunmodule XL bi-facial at Solar Power International in 2016. The high-wattage 72-cell module offers a 25 percent increase in power output due to its double-sided silicon technology. Another impressive feat by this new product is its improved solar capacity: a 330 watt SolarWorld panel will offer comparable output to that of a standard 410
