If there are solar cells, mount the cells on a sturdy surface, 3mm cold-rolled stainless steel.The joke is the rear glass roof will be the solar panel, so you can't get a metal option of that anyway.
Well what on top of the solar cells you think? Glass maybe?If there are solar cells, mount the cells on a sturdy surface, 3mm cold-rolled stainless steel.
Just so I understand, you are asking for a high/not high flag on topics Elon talks about in his Twitter feedā¦The most innovative twitter feature Elon could introduce would be a high/not high flag. Then we could sort what he says into two categories.
Itās pretty straight forward.Just so I understand, you are asking for a high/not high flag on topics Elon talks about in his Twitter feedā¦
Glass is common surface for solar panels but glass is not required and there are other materials besides glass used in production solar panels.The joke is the rear glass roof will be the solar panel, so you can't get a metal option of that anyway.
I thought you wanted SS roof so you don't damage the glass roof? If so a polymer coated solar panel is likely to be easier to scratch.Glass is common surface for solar panels but glass is not required and there are other materials besides glass used in production solar panels.
I don't think the solar powered cars like Aptera, Sono Sion use glass faced cells.
There are already some solar cells in production with stainless steel as the backing surface.

Sono uses a polymer-based solar technology that it developed. ā³We have several patents, over 30 patents on that,ā said Hahn. āAnd itās a big difference because all other companies who try to integrate solar are using most mostly glass. Glass is heavy, slow in production and very cost expensive.ā

Every Sunflare panel is made of our SUN2 cell starting with high-quality stainless steel, then layered with semiconductor materials only a few micrometers thick. The result is thin, lightweight and flexible solar. How thin is thin solar? Sunflare solar panels are 1.7 mm thick vs 100.0 mm for a traditional silicon solar panel.

Rugged TOugh
Our individual solar cells arenāt made from brittle silicon solar cells, which are prone to micro-cracking during transport, install, and long term wear. Micro-cracking can cause shorts within the solar panel itself and can lead to hotspots, burns, and even fires at its worse. Thatās not what you want in a solar panel.

SunPower Maxeon Walkable Marine Solar Panel
1. Highest energy yield (power output) of any solar cell commercially available.
2. Electric conversion efficiency of up to 24.4%
3. There is no glass and no aluminum frame so these panels are considerably lighter
4. Popular solar panels for boat roofs, docks, camper vans/RVs roofs and roof racks.

What solar panels does Aptera use?
Aptera is working with Maxeon Solar Technologies (formerly a division of Sun Power) as the cell supplier for its solar production program, and the carmaker's solar engineers have used the cells to create ultra-lightweight, curved solar panels. Aptera selected Maxeon Gen 3 solar cells because they are durable, lightweight and have minimal energy loss.

Sunman eARC SMF modules use an organic polymer composite to replace the typical glass front sheet as a laminant. The polymer composite material used is extremely durable, capable of withstanding extreme temperatures and climate conditions.
https://www.sunman-energy.com/eArc-lightweight-solar-product/details/15/
The weight of F series sits at 3.3 kg/ć” with a minimum bending radius of 0.5 m. The frameless design also removes the need of earthing a frame.
SMF modules can be glued directly to the roofs by "Quick-bonding." Quick-bonding involves no screw penetrations or mounting hardware, which simplifies the installation process greatly.
Applications
1. Curved Roofs
2. Low Load-Bearing Roofs
3. Waterproof Membrane Roofs

Abstract/Summary: We propose a new integrated photovoltaic module technology and manufacturing process for the seamless integration into box body roofs of commercial trucks to unlock a 90.2 GW potential in the EU. Our approach is to laminate c-Si photovoltaic cells with an ETFE-top cover onto conventional GFRP-hard-foam sandwich elements, which can be directly installed with conventional box body profiles. We find that VIPV modules must be lead-free and report results of Hot-Spot, Wet-leakage test and insulation tests to prove the electrical safety of the new concept. We perform UV, DH and accelerated TC testing on minimodules and find a mean PMPP drop of 3.6% for PERC, ribbon soldered half-cell modules after accelerated TC200 due to finger failure and partial ribbon disconnections. We conclude that conventional soldered ribbon based interconnection in combination with polymer based cover materials lead to unfavorable thermomechanical stresses in TC. We propose the usage of interconnection technologies that are less sensitive to thermomechanical stresses like Multiwire or shingling as we find that the mean drop in PMPP of shingle modules to be 1%. PERC Solar cells encapsulated using the proposed module design remain stable after DH1000 and UV 60 kWh/mĀ². We equipped a Mega electronics e-Worker with a photovoltaic active box body featuring the first generation of proposed module technology and reported initial monitoring results after 10 months of outdoor operation.

Yeah I saw that, but electro-mechanically slated solar panels that move up and down, and roll around a tube, as well as have to compete with dust and grime, doesn't seem like an effective way to do solar for me. I'd rather have a fixed solar roof in the glass, low cost and can be standard accross the range. Semi transparent cells would be great to give you that sunroof feel.The patent shows slats of individual solar panels forming the Vault roll-top. 15 miles added per day in good sunlight.
