Now a lot of the kind of solar energy hanging on the balcony, a board, that kind of effect is good,

The balcony should be wall-mounted, it has built-in electric heating.

The thermal collector element used in flat panel solar energy is not a vacuum tube, but a collector plate that also has a thermal collection effect is used to absorb heat, and conducts heat indirectly for water through heat transfer oil, so that there is no water passing through the entire collector part, and the part with water has the necessary thermal insulation treatment in addition to the thermal insulation part, and there is an electric heat trace on the outside of the water pipe to heat the water in the water pipe at a temperature of about 4 degrees under natural conditions, so as to avoid the water pipe freezing and cracking. The thermal collector panels of split solar energy are the same as ordinary solar water heaters, which are outdoorsThe difference is that the split solar tank can be placed anywhere you specify instead of being placed on the roof of the building, such as: >>>More

Wall-mounted, whether you need electric heating depends on your local climate. Of course, it is good, but it also costs electricity, so it is recommended to connect a small electric water heater.

The answer, of course, is yes. Balcony wall-mounted solar energy is a new energy-saving and environmentally friendly equipment with many advantages. Balcony wall-mounted solar energy has broad development prospects, especially favored by urban high-rise buildings, and has great potential in the field of household hot water and heating, and more and more families will choose balcony wall-mounted solar water heaters.

No, because the glass blocks some of the solar radiation, resulting in less heat exchange.
