You've probably already heard something about it. Photothermal basically consists of a hybrid system composed of a photovoltaic installation and a traditional electric heater . In this case, the photovoltaic installation supplies electricity to a single piece of equipment, the thermal accumulator. The electrical energy generated is used to produce heat. To do this, the electricity powers the electrical resistance of the thermal accumulator, heating the accumulated water. Easy, right?
At first glance it seems like a simple installation . It can be an alternative to thermal solar panels, although less complex because it requires fewer elements for its operation. It does not need circulation pumps, meters or pipes typical of a solar collector installation. The electrical energy generated is transformed into thermal energy that is accumulated by heating the water contained in the thermos . It also does not require as many elements as a photovoltaic installation. That is, photothermal does not require inverters or batteries to store the electricity generated.
Advantages of photothermal
In this link you can check with an image what photothermal consists of: PV Solar Boiler. Water heating using solar electric-photovoltaic-PV
The advantages of having such an installation compared to one with solar collectors can be:
Less maintenance than a more complex solar panel installation with more elements for its operation.
Longer useful life and warranty time. No risk of overheating.
Architectural integration. Photovoltaic modules are more easily integrated into the building envelope. Therefore they do not need as much inclination as solar panels.
DB HE justification. It allows justifying Phone Number List the current DB HE Minimum solar contribution to domestic hot water , as an alternative to the reference system.
Composition
The complete system is made up of :
Photovoltaic solar panels connected in series and support for their integration into the building roof. The number of panels will depend on the amount of hot water to be generated.
DC protection panel . This is a safety mechanism for both people and equipment. Ensures the proper functioning of the installation and prevents incidents.
Charge regulator and control . It consists of a device that directs and controls the amount of energy generated in the photovoltaic panels. Also the production of hot water.
Electric accumulator thermos of different capacities.

thoughts on “ Photothermal for DHW production. What does it consist of? ”
I have already carried out several DHW production projects with this photothermal system in different places with different climatological situations and I can assure that it is a system of great energy efficiency and use of solar radiation, making the water an energy accumulator and having reached temperatures of ºC. There is also an installation in operation to support underfloor heating since in the middle of winter temperatures are obtained in the inertia accumulator of up to ºC, which allows great savings in primary energy since the temperature of the underfloor circuits does not usually exceed ºC and in many seasons it remains below ºC so the boiler stops and only works with solar input.
