South-facing solar panel systems almost always generate the most electricity, but east-west roofs can work well for solar, too. The direction is more important than the angle. Angle is rarely a make-or-break factor, and most roof tilts will work fine—though there are some exceptions. [pdf]
[FAQS about Solar PV panels by direction]
A grid-tie inverter, often called a grid-tied solar PV inverter, is the go-to for straightforward solar setups. It takes the direct current (DC) from solar panels, converts it to alternating current (AC), and sends it to the grid. [pdf]
