The panels do not require any more maintenance than cleaning the glass periodically (quarterly recommended).

Yes, in fact, it is advisable to replace worn-out panels of simple technology, with hybrid ahtech‍ technology since the production of the installation, and therefore the savings obtained, will increase considerably. The combination of the two technologies, thermal and photovoltaic, in a single panel, also allows to optimize the available space in the roofs of the buildings.

Because the energy production of each technology is very different. A hybrid panel generates the same energy as 5 photovoltaic panels and costs less than 5 photovoltaic panels. Therefore, to generate the same energy, it is a more economical and, consequently, more cost-effective solution. By analysing the savings over the lifetime of the installation, hybrid panels achieve savings about three times higher than those achieved in photovoltaics. As an example: in a 4-star hotel with 200 beds, if 70 photovoltaic panels are installed the accumulated cash flow in 25 years (total economic savings) is 220,994 € and if hybrid panels are used, the savings achieved is 576,056 €. So, clearly with hybrid solar panels are not only the most profitable, but they are the ones that achieve the most economic savings, energy and emissions. In addition, it will be very important to take into account the temperature range to which the hydraulic circuit will work, since the performance of the photovoltaic part increases if the cell temperature is reduced. And in most applications, the temperatures at which cells work on a hybrid panel will be lower than those of a photovoltaic panel. For example, in low temperature applications such as swimming pools this "cooling" effect of cells can increase photovoltaic production by up to 12%.

The steps to follow for the installation of hybrid panels are indicated in the different manuals available in abora docs.

A solar installation requires a support system. There is no specific technology needed, you can use a gas boiler, electric thermos, heat pump, aerothermia...
