Basics about solar panel battery charging.
Panels
Monocrystalline panels are regarded as being the most efficient panel technology. Second to Polycrystalline panels.
Common configurations of individual panels:
- 100W - common
- 120W
- 150W - common
- 160W
Arrays are usually build by parallel installation of multiple of the same panel type, e.g. 10x150W panels is a 1500W or 1.5kW array.
Some cheap flexible panels:
- 100W 18V Mono panel - 137USD
Solar controllers
There are two kinds of controllers; MPPT and PWM charging mode, with the former being the preferred one on larger (>50W) setups.
A reasonable decent solar controller starts at 50USD, for a 10 to 30A 12V setup.
- Solar controller 30A 12V - 44USD
Batteries
Using regular 12V or 24V batteries makes it simple to get locally.
