The
Victron Energy Battery Monitoris one of the best you can buy. There are several models, depending on what "additional" bells and whistles you want.
On the panels them selves, the first thing you need to decide is what physical size. "Standard" home panels are 2m x 1m (over 6' by over 3') and 72 cells. These are difficult to handle it you are on a roof. You can easily find 1/2 size panels, 1m x 1m and 36 cells, easier to handle but more connections. The other consideration is monocrystalline vs. polycrystalline. Mono are more efficient but cost more. 200W per square meter is consider "good".
I do not have enough experience to recommend brands beyond the battery monitor. For the charge controller, you probably can not go wrong with any of the name brands.
At the moment, the Chinese built panels have a large tariff. Some distributors are getting around this by purchasing from suppliers in other parts of Asia. There are some solar panels being built in South Korea.
