Earlier generations of Si-PV last longer, for example the original Si-PV cell (1 cm thick), 70 years old, is still operational.
"The thickness of the solar cells has been decreased... These changes have rendered the cells more brittle and susceptible to fracture while handling, storage and lamination of the module."

Newer PV is thinner, cracking easier, shortening lifespans, causing concern that multiple PV product generations will expire at the same time.
"Due to silicon cell cracking, Photovoltaic (PV) module reliability issues are gaining great attention due to the increasing demand for solar power and the reduction of cell thickness to reduce cost."

Uneven American demand for #housing limits #Modular #Construction in the US:
"'Factory-built housing has the potential to reduce hard (labor, material and equipment) costs by 10 to 25%'... Factories are hugely expensive to set up and run. Off-site construction companies only stand to make up those costs if they can run continuously and at full capacity."
Building homes inside a factory has long been seen as a way to revolutionize the American housing industry, ushering in a new era of higher quality homes at lower price. That dream has never quite panned out. Can California finally make it happen?
