1. First of all, I personally think that flat panel solar energy cannot be chosen in areas north of the Yangtze River, because flat panel solar energy can only be applied to temperate and tropical areas . The solar energy of flat panels during the day is better than that of vacuum tubes. It is higher, but at night, the heat dissipation effect is almost the same as the heat collection effect. Therefore, it is recommended to choose vacuum tube solar power. You can consider Huangming Solar as your first choice.
2. For auxiliary energy, choose electricity. After all, it's much more convenient. Because, if we choose solar energy with evacuated tubes, electrical energy assistance will not be used too much.
Can underfloor heating and solar energy be used together?
1. Heating and comfort. Underfloor heating is the methodmost comfortable heating method. The effect of solar floor heating is the same as that of traditional floor heating. It follows the ergonomic principle of warm feet and cool head.
2. Solar underfloor heating has extremely low operating costs and requires almost no energy consumption. The ratio of solar panels to heating area is sufficient to meet the load requirements. In bad weather, only a small amount of auxiliary energy can be used to meet heating needs.
3. Clean, environmentally friendly and pollution-free. Solar energy is a clean, renewable resource that does not pollute the environment.
4. The constant temperature heat storage module also has the function of maintaining a constant indoor temperature in summer. There is no need to turn on the air conditioner or reduce the frequency of the air conditioningatization and energy consumption. The constant temperature heat storage module not only reduces the indoor temperature, but also prevents the feeling of cold wind and no power consumption.

It's possible, but there are many conditions.
First of all, it is necessary to insulate the house well, such as wall and window insulation, otherwise the heat dissipation will be too fast and the heating effect will not be good.
Second, there is enough surface area to deploy solar energy. If the surface area is too small, the heat collection effect will not be effective.
Third, a hot water storage tank is necessary to store water heated by the sun during the day for use at night or when the weather is bad. The water tankis large enough and the insulation effect is good. enough to store hot water heated by the sun in summer. Use it in winter.
The fourth solar energy is after all not stable, so it needs an auxiliary electric boiler or similar. Additionally, the system must be designed in such a way that the electric boiler cannot be used to heat water from the water tank.
The fifth problem is lifespan. It is best to use a black, porcelain, old or old heat-absorbing layer that will not decompose and can be used for more than fifty years, otherwise the investment will be too high.
