Solar 2020 Part 8: Underground Conduit and DC Wire Pulls
The worst part of the project, easily, was doing the conduit work. It was the middle of summer, the air was thick with smoke from the fires all over the west coast, and I was outside doing an awful lot of digging with a pickaxe and trenching shovel.
I have 6 stings of #10 thhn entering my basement. The amperage is 11 amps/string. My EG4 inverters are about 50 lineal ft away from the basement entrance. I''m thinking I should run the strings in pvc …
Buried-in interface with two-terminal functional groups for perovskite-based photovoltaic solar cells
Interface plays an important role in perovskite solar cells. Herein, a functional molecular with two-terminal donor groups was deposited between the tin oxide (SnO2) electron transport layer and halide perovskite to induce the perovskite crystal growth and passivate defects at the interface. It is found that isonicotinohydrazide (INHA) can …

Thin-Film PV Cells: The most versatile of the bunch, thin-film cells are made by layering photovoltaic material on a substrate. These cells are lighter and more flexible than crystalline-based solar cells, which makes them suitable for a variety of surfaces where traditional panels might not be ideal.
Typically, water lines are buried at a depth ranging from 18 inches to 5 feet, depending on various factors such as local climate, soil conditions, and the type of water system in place. In colder regions, where frost penetration is a concern, water lines are often buried deeper to prevent freezing and potential damage.
