I see, your argument is that like (for instance) LendingClub, the economies of scale always favor large investors, and that this platform simply cannot get large investors onboard. That may be due to a lack of connections, or due to some other potential fundamental issues with the business model. At the end of the day if the business is sound it makes more sense to target fewer large investors - not many, smaller one…
No one in their right mind wants to build a pseudo-investment company dealing with tons of small investors in the few hundreds of dollars to few thousands of dollars range. The only thing missing here is a crypto coin. If they really have a business model that can yield 8+% annual, assuming they get a cut, then they would raise real capital and not deal with randos. They don’t.
There's a "wallet". They keep your returns until you ask for them and get them to pay out.
If you're really buying a solar panel, you're buying a depreciating asset. Someday the solar panel will wear out and your investment is gone. So the return has to cover the amount invested. An annual percentage rate is not the way to evaluate this.
What you buy does not seem to be resellable. It looks like you're stuck with it for the life of the hardware.
Who audits this thing?
This is almost exactly the classic situation in SEC vs. Howey, where investors bought trees in an orange grove. So this is probably an unregistered public offering.
