More solar panels can be installed on footbridges.

Solar panels have recently been found on many footbridges across the island, particularly the vast majority of pedestrian Bridges on the pan-island expressway.

What's interesting is that the footbridge is fitted with a solar panel one or two meters away. In fact, the entire flyover has been filled with an entire row of stents, and why not install solar panels on each bracket instead of installing them?

The solar panels installed in the footbridge belong to the grid-connected system and all the electricity generated is injected into the grid. The scale of the grid-connected system is more and more suitable for installing solar panels as long as there is enough space and not covered by trees.

Since the authorities have already spent money and manpower to install stents in the entire flyover, it is clearly not in line with the economic benefits. If it's a matter of weight, a solar panel battery weighs about 10 kilograms, which is not heavy.
