First: it's beautiful.
Secondly, the installation is convenient.
In terms of configuration, I think monocrystalline silicon is better than polycrystalline silicon, and the price difference between them is not big, but the conversion rate of monocrystalline silicon is higher. You can save electricity faster.
Light, led light is preferred.
Battery: Lithium battery will be better. Because lithium ferrous phosphate is more resistant to high temperature and has a good power storage effect, but it is more expensive and more cost-effective.
