The problem is it’s very expensive. Solar installers charge tens of thousands of dollars and has a long history of scams. They take the place of the old trope about scammy used car salesmen. They’ve created leases and PPAs in an attempt to make the initial cost easier but only succeeded in being scammy
It doesn’t help that we have tariffs and other barriers to low cost solar panel imports, yet insufficient support for domestic manufacturing to be competitive.
The math is hard. Everyone wants to know the payback threshold from the huge install cost up front but it’s not straightforward.
When I looked into solar I found
- lots of scammers, poor service
- I calculated a payback of 12 years from install cost given free energy, which is longer than I’m likely to own this house. But they claim 7?
- I only have sufficient unshaded roof for half my usage
- is it poor service or scamminess that it’s so difficult to get them to explain that?


I disagree. Most of them are shit because they’re designed to serve the manufacturer, provide additional profit streams.
However there’s no reason they couldn’t provide useful functionality to the customer.
The most frustrating part is makers of smart appliances can save money by making them cheaper. Instead of a WiFi chip and vendor portal, just embed a dirt cheap Thread radio that simply exposes whatever is useful and let the customer take it from there, or not. Most smart appliances stuff people would find useful is monitoring and alerting, locally
