>...This is why residential solar get such stiff propaganda against it by utilities, going as far to say that residential solar "freeloads" on the grid The problem with rooftop solar is that it is very expensive compared to utility grade solar: >…Rooftop solar photovoltaic installations on residential buildings have the highest unsubsidized levelized costs of energy generation in the United States. If not for federal and state subsidies, rooftop solar PV would come with a price tag between 147 and 221 U.S. dollars per megawatt hour. https://www.statista.com/statistics/493797/estimated-levelized-cost-of-energy-generation-in-the-us-by-technology/ https://www.statista.com/statistics/493797/estimated-leveliz... If we want to subsidize a renewable energy source, why should we subsidize rooftop solar when we could subsidize utility grade solar or wind? Money is fungible and not unlimited - a dollar that goes to subsidize residential rooftop solar is a dollar that would go much, much further if it was used to subsidize utility grade solar or wind. Rooftop solar subsidies are also unusual in that much of the subsidy is often paid by less well-off households to subsidize their wealthier neighbors - sort of a reverse Robinhood scheme.

Residential solar is very inexpensive if you install it yourself. 3kW solar panel is $195.90 [0]. 10kW battery is $2200. [0] https://www.aliexpress.us/item/3256806170563774.html https://www.aliexpress.us/item/3256806170563774.html

  Something's off there. From the product description: 3000WProduct Description Widely used: Under 4 hours of full sunlight, the daily production capacity is 400wh/day. It is very suitable for RVs, caravans, oceans, camping vehicles, electric scooters, golf carts, power wheels, fishing motors, tool trailers, and backup power sources for small sheds. 【 Excellent Performance 】: Single crystal solar panels are made of corrosion-resistant aluminum frames, which can be used for more than ten years and can withstand strong winds (2400Pa) and snow loads (5400Pa). IP65 rated terminal box and 21% high battery efficiency. [Easy to install]: Pre drilled holes on the back and plug and play cables allow for quick installation 【 Multi protection 】: 20A PWM controller: built-in short circuit, open circuit, and overload protection to ensure safety. And it supports three types of batteries: lithium batteries, lead-acid batteries, and colloidal batteries. Technical parameters: Rated power: 100W

    Single listing for multiple items. Second item is 100W panel 24x35cm for $22. The last item is supposed to be 3kW panel 98x54cm. I wouldn't buy from a seller with such messed description.
