Hantile flexible solar tiles by Hanergy.

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.

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

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!

Tractile solar roof tiles global rollout!

Australian company Trac Group have released their Tractile solar roof tiles locally and are now preparing for a global rollout of their Building Integrated Photovoltaic (BIPV) product.

About Tractile Solar Roof Tiles

The Tractile solar tiles use the Roof Integrated Photovoltaic and Thermal (RIPV-T) system, which, according to the Tractile site, is an “exciting new technology which merges photovoltaic (PV) and thermal systems, simultaneously providing both electric and thermal energy”. This means the system is able to greatly increase performance in hot conditions due to the thermal energy generation cooling the PV cells – leading to more energy generated per square metre when compared with conventional PV panels and solar thermal collectors.

The solar roof tiles come in 4 different types:

  • Eclipse Roof Tile – a ‘normal’ superstrong roof tile you use in parts of the roof that aren’t north facing/receiving strong daily sunlight.
  • Eclipse Solar Roof Tile – electricity and solar boosted hot water generating tiles. Cost effective, lightweight, aesthetically pleasing and increased PV output (compared to conventional PV systems)
  • Eclipse Thermo Roof Tile – interlock with Eclipse roof tiles and Eclipse Solar roof tiles to maximise solar heated hot water output.
  • Horizon Roof Tile – electricity and solar boosted hot water generating tiles to merge into new or existing concrete tiled roof.

The tiles integrate four key elements into one product:

  • Roof system
  • Photovoltaic (PV) cells
  • Solar thermal collector
  • Insulation

Tractile vs. Tesla Solar Roof

Trac Group managing director Jason Perkins has been quoted on the impending release of the Tesla Solar Roof saying it will increase Tractile sales, saying: “It’s fair to say that when you compare the Tractile Solar Roof tiles with the Tesla products, the Tesla products are simply left in the shade”. “Regardless of whether it’s the price of the roof, the weight of the roof, the amount of electricity and hot water it produces per square metre or the options for the roof lines, our products compare very favourably.”

The Tractile site has this comparison image which shows the Tractile very competitively priced for what you get:

Tesla Solar Roof Alternatives

While we wait for the Australian release date for the Tesla Solar Roof, there are some alternatives.

German company Sonnen have partnered with Bristile Roofing to offer the Solartile, which is looking quite interesting.

Obviously we also have the Tractile Solar Roof Tile, which is available from their website by clicking here, or call their Australian support line on 1300 00TRAC. If you want to learn more about the Tractile they have a ‘downloads’ section on their website which as a Tractile Eclipse product specification, benefits, roof config options, introduction brochure, and much more.

Australian Tesla Powerwall 2 Installation Guide

Finally, after a litany of false starts and delays, Australians are beginning to enjoy installations of the Tesla Powerwall 2. Michael V, a user on the Australian based Whirlpool forum, documented the process of his install in a thread yesterday and it looks like the process went fairly smoothly, despite the fact that according to Michael it was the installers’ (Flashpoint Electrical and Solar at Punchbowl) first ‘actual’ install (i.e. they had practised on a prototype before but this was the first customer install). According to Tesla’s Facebook page, on April 28 they said that “Powerwall 2 installations have begun in Australia” but this is the first documented information we have on the process so please have a read and let us know if you have any questions or would like to share your experience with Australian Tesla Powerwall 2 Installation in the comments. We’d love to hear about it.

Tesla Powerwall 2 Installation and Ordering Process

The installations management team will help you with the Powerwall install process, which is, as far as we can tell, as follows  (please note this is after you’ve already pre-ordered a Tesla Powerwall 2 – there’s a ~2 month backlog in Australia right now so if you’re on the fence (wall?) about it then click here to visit Tesla’s site and order.

The Powerwall Install Process is as follows:

  1. A Tesla Certified Installer (from Downer Group, in Michael’s circumstance) visits your property to carry out a ‘site assessment’ – which will check:
    1. The suitability of your preferred location for Powerwall 2
    2. Site specific information for Tesla to provide a cost proposal for installation.
  2. A ‘proposal and sales agreement’ is prepared and sent within 7 days. Full payment is required 2 days prior to install.
  3. A Tesla Certified Installer visits your premises to install your brand new Powerwall 2!
  4. Powerwall 2 is connected via 3G (preferred) or Wifi so you can update the firmware and use the Tesla Powerwall App on your phone/tablet.

If you’d like to learn more about the actual install process, click here to view the full album of photos from Michael V on Whirlpool.
