Chinese company Hanergy have released the latest generation of their flagship Hantile flexible solar roof tiles. They’re lighter, thinner, more flexible, and have increased performance from the previous generation. Let’s have a look at how they stack up against some of the other solar roof tiles on the market.
Hantile Flexible Solar Roof Tiles
The new Hantile uses a single instead of a double layer of glass. This has lowered the weight of each tile down to 5.2kg. The glass is ultra-white tempered so it is extremely durable and is able to deliver a transmittance level of 91.5%. According to the PR News wire, the single glass Hantile can generate power at temperatures ranging from -40 Celsius to -85 degrees. Their life cycle is 30 years and each tile uses copper indium gallium selenide solar cell (CIGS) with 17.52% efficiency. In terms of environmental friendliness, each 100 square metres of Hantile is equivalent to planting 340 trees. The tiles are backed by a lifetime warranty (30 years) and a lifetime charged maintenance guarantee.
“We’re delighted to introduce the next generation of our innovative Hantile building solution,” said Hanergy founder Mr. Li Hejun. “With its industry leading energy generation capabilities and suitability for any building, I am confident that Hantile will set a new benchmark for new energy applications in building construction.”
Hanergy is, according to their press release, the world’s largest clean energy company. They work with hydro-power, wind power, and solar power. Since 2009 they’ve been researching thin-film solar power and with their updated technology will be releasing solar roof tiles, foldable solar-paper power banks, solar backpacks for solar camping, BIPV, solar roads, and more. They have more than 16,000 staff members and have been in a bit of financial trouble recently with the SFC ordering them to pay outstanding debts to its subsidiaries, with the stock currently ceased trading on the Hong Kong market. Hopefully this new technology can help Hanergy get back on track.
Hanergy Hantile vs Tesla Solar Roof
The Tesla Solar Roof has been talked about a lot over the past year, but there have been quite a few competitors sticking their hands up such as the Tractile solar roof tiles, which are a lot more price effective than Tesla’s offering. Hanergy’s new Hantile don’t currently have a price for Australian install, but it looks like the ‘c-type slot structure’ they used for manufacturing mean it will be quite easy to install them. The previous Hantiles, launched in 2017, had a conversion efficiency rate of 16.5% and it now boasts 17.52% conversion rate.
The price of last year’s triple arch solar tile was 130 yuan ($~285 AUD)/ m2 so it’ll be interesting to see what the new tile costs. We’ve reached out to Hanergy for comment and will let you know as soon as we have more information. We’ll be looking for reviews, price, release dates, and more!
