Should they sell this product to another firm that will get it done? Or is there a lower cost, safer, more sustainable product? With a compatible part stream?
Best solution for a residential setting is a standing seam metal roof with friction mounted racking and panels. 40-50 year lifetime, minimum, with no chances of leaks due to no need for penetration through the decking. Commercial and industrial use cases usually use ballast solutions without roof penetrations.
The other day on YouTube I saw a solar shingled roof that pointed down into a rainwater cistern; a roof with circular curved negative pitch for rainwater collection.
Apparently metal roofs (and copper gutters) are best for rainwater collection but not for WiFi or cell reception.
Heating pool water with attic heat and a relief tray is a thing already.
Direct Immersion of thermally-inefficient electronic GPUs/ASICs/FPGAs in a thermofluid in a closed loop with an exchanger coil is an efficient way to heat (pool) water.
There's also an article on HN today about a new residential R-744 (CO2) heat pump.
A greenhouse in the attic under TPV Thermophotovoltaic agrivoltaic-like translucent panels would be useful.
Attics can dry things out; clothes, food.
I watched a different video on YouTube about how old houses were built to manage seasonal thermal variance before electric AC compressors ruined life; OTOH: double-sashed windows, above-door vents, vault ceiling, covered shaded wraparound porch, upstairs screened-in sleeping porch, oculus tower, widow's porch, window awnings, roof overhangs, attic fan, chimneys, the stack effect.
By varying the color of the chimney, you can maximize the stack effect through the days and nights and the seasons.
An rGO Lignin-Vitrimer active metamaterial works like an ePaper device: the rGO (reduced Graphene Oxide) particles change phase (flip over) when charge is applied and then hold position without applied voltage for months. This part, rGO Vitrimer an metamaterial, has a high degree of centrality amongst the product manufacturing processes I've modeled in my sustainablefactory project: communications, nanolithography, imaging, and also building materials; siding, chimney siding, roof tiles.
A few materials also from the sustainablefactory project; AKA Lignolux instead of "ACME Corp":
LVP: Lignin-Vitrimer Perovskite would be a durable, fully-recyclable product. LVCF (Carbon Fiber) or LVH (Hemp) are also probably ideal materials for solar panels.
A solar panel mount could harvest energy from wind using TENG and piezoelectrics with Laser-Induced Graphene; similar to how bladeless wind turbines harvest wind energy. With safe batteries there would be energy to defrost and ultrasonically clean panels.
A motorless tracking solar mount could pulse electricity through LIG graphene traces in the LV/LVCF/LVH to use the material reset (Todo terminology) to keep the solar panels pointed at the sun.
Flower-shaped solar arrays are smart because flower petals are self-cleaning.
Aluminum Ion Omni Carbon batteries would last for 10-50K cycles without risk of thermal runaway.
Sonic fire suppression is commercially available now FWIU.
Carbon-based fuses originally designed for in-ocean coastal fortification might also be good for solar applications.
Carbon-based capacitors and transformers originally designed for fusion plants can be immersed in a sustainable thermofluid alternative to castor oil like LBGPC (Lignin, BioPG, Graphene, Phytic acid, Citric acid) or modified Farnesene-Isoparrafin.
Farnesene-Isoparrafin for direct immersion of unmodified electronics.
Lignin melts in the sun, but Lignin-Vitrimer (which you can make with a low-cost Zinc catalyst) can have a glass temperature from like 85-180C.
Lignin is UV resistant and can be used as a sunscreen.
To make Lignin-Vitrimer fire-resistant, add Phytic acid and optionally Carbon Nanospheres or just non-crystalline amorphous sol-gel silica: SiO2.
Are there yet TPV panels for a standard friction-mounted rack?
Does anyone round or bevel the corners of rooftop panels to cut the shearing force and racking? Round homes on pylons fare best in costal storms FWICS.
PV farms in the Carolinas have a way to batten panels down to the ground to weather storms.
LVP Lignin-Vitrimer Perovskite could also be used for medical imaging. So scaling production of LVP panels from would also benefit clinical medicine and patients.
I made myself write all of this up without looking at a lot of pages of AI chat sessions.

Through sheathing, wrap that ruins sheathing FWIU, Zip tape.
According to YouTube, aluminum-coated foam sheet insulation tacked to risers with a gap like an interior ridge vent is an efficient roof insulation method.
Glauber's salt (Sodium Sulfate) is a PCM Phase-Change Material that melts at 90F and starts absorbing energy; but it has to be mixed with at least Borax and water to make a 5gal DIY AC system FWIU.
Home Renovision DIY has a video on new deck attachment codes in Canada that might be relevant for this.
