Trumpâs order waives the tariff for the first 2,500 MW of panels, and then the tariff kicks in at 30% on any excess. Thatâs for the first year only; the tariff then steps down 5% over 4 years to 15%, and then goes away. This is also the same time horizon for which the solar Investment Tax Credit (ITC) disappears.
The International Astronomical Union (IAU) currently recognizes five dwarf planets: Ceres, Pluto, Haumea, Makemake, and Eris.
Some astronomers called Eris our Solar System's tenth planet when it was first discovered. After a lot of discussion, astronomers decided to make up a new category for objects like Eris. That is where the idea of dwarf planets came from. Eris was discovered by Michael Brown, Chad Trujillo, and David Rabinowitz.
