Photovoltaic water heater

The new generation of photovoltaic water heaters is a product that can be directly used without grid connection. It is not only suitable for single-family applications of the majority of residents, but also perfect for the renovation of newly developed buildings and old residential areas. At the same time, photovoltaic water heaters can replace traditional solar water heaters and no longer use media. Developers will have simpler designs and more convenient construction, which completely solves the drawbacks of traditional water heaters.

Photovoltaic water heater

Principle of photovoltaic water heater

Photovoltaic transmission line photovoltaic water heater, is to use sunlight to irradiate semiconductor material photovoltaic panels to form electromotive force, thereby generating unstable DC power supply (light-to-electric conversion), and then through the connecting wire to the DC heating device to convert into heat energy (electric-to-heat conversion). Because the heat capacity of water is relatively high, and the water tank has good thermal insulation performance, the water tank can store thermal energy.

Therefore, the "photovoltaic water heater" that directly heats the water tank with photovoltaic electricity does not need to be connected to the grid, does not need to be stored, and does not need to be inverted. Because there is no intermediate conversion loss, it has the characteristics of no fossil energy consumption and high photovoltaic power utilization.

Photovoltaic water heaters only need to cooperate with a small amount of auxiliary electric heating on cloudy days, rainy and snowy weather, so it is both environmentally friendly and energy-saving. Compared with traditional solar vacuum tube water heaters, balcony wall-mounted solar collector water heaters, air source water heaters, electric water heaters, and gas water heaters, they all have unique advantages.

Current status of photovoltaic water heaters

The basic working principle of photovoltaic water heaters is simple, and its advantages are also very obvious. Therefore, many companies have been researching and developing them many years ago. However, due to the instability of photovoltaic power supply, the regionality of light intensity, and DC arcing, etc., there has never been a very perfect product launched on the market.

The "Jieyang" water heater solves the problem of maximizing the efficiency of electric heat conversion through big data analysis technology, solves the problem of DC arcing through contactless control technology, and develops and produces a truly practical photovoltaic water heater with dual temperature and dual control, photovoltaic panel boosting, and total power distribution algorithm.

Features of household photovoltaic water heaters

Split structure design, photovoltaic modules are installed on the roof or outside the balcony, without the need to install circulation pipes, insulation and heating tape, which makes installation easier, location more flexible and maintenance simpler.

No circulation pump is required for forced circulation, no buffer water tank, water filtration, antifreeze and other systems are required, and the operation mode is simple. The photovoltaic hot water system is connected by cables, without the risk of water leakage, and the failure rate of wires is low, so the later maintenance cost is less and it is safer to use.

The efficiency of photovoltaic conversion to electricity is higher in winter, and there is no heat source outside the water tank, so the heating advantage in winter is obvious.

Photovoltaic electricity and mains electricity dual temperature and dual control, with appointment function, mains electricity complementary function, and remote control function. The normal service life of photovoltaic modules can reach more than 20 years.
