Which new solar panel technologies could revolutionise energy production?
In this post, M+H Power New Zealand has taken a detailed look at six solar technologies that may impact on the solar industry over the coming years. M+H Power is currently in traditional mono and poly crystalline roof top or ground mounted solar panels for residential and commercial applications. These tried and tested technology dominate the New Zealand solar market.
M+H Power always review all new technologies in terms of reliability, performance, commercial viability.
2021 new solar technology — where are we headed?
There are several interesting new solar panel technologies either in the pipeline or just commercialising in the market. These promising technologies could potentially revolutionise the way we think about not just solar, but energy production in general.
1. Floating solar farms (‘floatovoltaics’)
“Floatovoltaics” are photovoltaic solar power systems created for floating on reservoirs, dams, and other water bodies. Currently, there is limited trialing occurring overseas with this technology.
Floating solar farms can generate huge amounts of electricity without using valuable land or real estate. The installation costs of floating photovoltaic panels are less than land-based photovoltaic panels. Besides producing clean solar power, floating solar farms can help with water management. They reduce the loss of water to evaporation as they limit air circulation and block sunlight from the surface of the water. Also, floating solar farms prevent noxious algae production, lowering water treatment costs. Furthermore, the water beneath keeps solar panels clean and minimizes energy waste.
2. Solar Roof Tiles
The concept of residential solar roof tiles was first announced in Australia nearly five years ago, and recently launched into the market. However, currently, it is not available in New Zealand at all. Although a lot of interest in the concept, the price on roof is prohibitive expensive versus other traditional installation methods. It’s currently over twice what you would pay here for a high-quality tile roof and an equivalent standard solar system.
The solar product looks like a normal roof tile, but it isn’t cheap!
3. Building-Integrated Photovoltaics (BIPV) Solar technology
Building-integrated photovoltaics seamlessly blend into building architecture in the form of roofs, canopies, curtain walls, facades, and skylight systems. Unlike traditional solar PV panels, BIPV can be aesthetically appealing rather than a compromise to a building’s design. BIPV technology, when used on the building's facades, atrium, terrace floor, and canopies, provides the following benefits:
Increased energy efficiency
High thermal and sound insulation
Clean and free power output from the sun
Decreased O&M costs
Zero carbon footprint
The photovoltaic PV glasses installed as building materials act as an energy-generating device, allowing natural light inside homes and offices, just as conventional architectural glass.
4. Solar Skins
Solar skins are a novel PV technology to integrate custom designs into solar panel systems. The solar skin technology is like the ad wraps displayed on bus windows. A manufacturer in the US is testing the concept of solar skins. At this stage, this technology is not in New Zealand, however, there are certainly commercial interest in the concept.
Solar thin-film skins maintain high efficiency due to its selective light filtration advancements. The sunlight falling on solar skins is filtered to reach the solar cells beneath it. Solar skin panels can also be beneficial for businesses or government offices. They can be customized to display business logos, business advertisements, a country’s flag, and so on.
Solar skins utilize rail-less racking systems, sit lower, have a sleek finish, and hide metal components, giving the panels a super cool look. An interesting aesthetic style product.
5. Solar Fabric
Solar radiation is available all over the planet, so why not generate your own energy, wherever required? Imagine that besides producing solar power at a fixed location, you could also do it while on the move through your own clothing.
Researchers are developing solar fabrics with a vision of including solar power in each fibre. These solar filaments can be embedded into your t-shirts, winter coats, or any other clothing to help you keep warmer, power your phone, and provide energy for other needs while you’re on the go.
There are several areas where researchers have attempted to combine solar fabric and solar panels, which include:
Building facades that provide both shade and power.
Awnings that lighten up streetlights, and
Curtains that eliminate power consumption from the grid
Solar fabricated household clothing can help you save on solar panel mounting and installation costs.
6. Photovoltaic solar noise barriers (PVNB)
Highway traffic noise has always been a concern for everyone impacted. To overcome this issue most states have adopted various formats of traffic noise barriers.
Noise barriers were always constructed with the single aim of designing cost-effective barriers that efficiently perform noise abatement functions. However, now overseas companies such as US Department of Energy are setting new goals such as merging noise abatement with sustainable power generation.
This also will be of interest to New Zealand Government bodes such as Ministry Of Transport and Department of Business, Innovation and Employment as the concept evolves.
