SOLAR PANELS - GENERAL

Solar water heaters use solar energy as a means of heating to produce domestic hot water. It is an alternative option for the production of domestic hot water, which is completely environmentally friendly and is considered ideal for areas with great sunshine, such as Greece.

Our solar panels are manufactured according to international standards and carry all the certificates and test reports that confirm their quality. The water storage tank (boiler) has an internal coating of enamel (glass), which coats the tank internally at every point to protect it from rust, thus ensuring clean drinking water at all times. Their collector is selective, the type most commonly used in recent years in solar water heaters, as it has lower heat losses than a simple collector, and therefore higher efficiency.

SYSTEM FEATURES

Both the boiler and the collectors of the installation are manufactured on the basis of the following characteristics that serve the high requirements of the enterprise:

- Solar water heater solar boiler:

• Stainless steel outer lining for unlimited resistance to harsh weather conditions.

• Strong polyurethane (ecological) insulation up to 60mm thick and 40.5 kg/m3 for complete thermal insulation.

• Water tank (boiler) made of special steel 1204 V. E. 3mm thick special for glazing.

• Tightness check at test pressure up to 15 ATM.

• The boiler is protected internally by double successive layers of hard glass (DURO-GLASS) according to DIN4753 / 3-5-8 baked at 830°C.

• Horizontal welding of the container internally and externally (unique innovation).

- Solar panel:

• Certified energy efficiency - The collectors have superior energy efficiency levels and meet the EN 12975 standard. All of these have been rigorously tested in certified research centres. The new products have been awarded the Solar Key Mark and the P-ICIM quality certificate.

• Longer duration and safety - The collector's glass, 4mm thick, with special reinforcement, high transparency and resistance to sudden temperature changes, reflects poorly the incident sun rays, thus losing minimal energy. The solar energy captured is retained thanks to the prismatic surface and thus creates a "greenhouse effect" inside the collector.

• In addition, the collector, for full absorption of solar radiation, has a heat-absorbing surface made of specially shaped aluminium blades with semi-selective colour treatment and for full sealing and robustness a specially shaped frame made of aluminium profile and an additional special rubber profile above the crystal. It is also insulated with prepainted pressed hard glass wool up to 45mm thick.

These easy-to-use systems are manufactured by combining the most economical and efficient operation of a solar system with aesthetics. Thus, it is possible to place the collectors on the roof of your house and the boiler in the boiler room.

SYSTEM DESCRIPTION

As in heating systems, heat is transferred through a heat transfer liquid which runs between the solar collector and the cylinder. The liquid (a mixture of water and glycol) can flow spontaneously or move from a circulator. Based on this we can distinguish two types of solar systems:

- Physical Traffic System:

• Simple

• Reliable

• Financial

• Reduced maintenance

- Forced Traffic System:

• Efficient

• Flexible

• Architectural integration in combination with the boiler

Also, the water heater can work even in the absence of sun, heating the domestic water through an alternative source, saving energy. Based on this we can distinguish two types of solar systems:

- Dual energy:

They are the systems that have the ability to work in two ways: by solar or by electricity. This means that inside the water tank there is an electric element, so on days when there is little sunshine due to cloudy weather you can turn on your solar water heater with electricity, and always have hot water.

- Triple energy:

They are the systems that can work in three ways: with solar energy, with electricity or with hot water from the central heating of the house. This means that inside the water tank there is an electric element, as well as a coil in which the hot water of the radiators produced by the central heating boiler/pump circulates. So on cloudy days, you will be able to start your solar panel either with electricity or from the boiler, so that you always have hot water.

This function is controlled by a differential thermostat. Taking into account the climatic peculiarities of each place, differential solar thermostats are an ideal solution for maximum efficiency and fuel economy. They are doubly protected against lightning and electrostatic discharges. They can perform an anti-icing program to protect the collectors. They are fully digital and configurable with a built-in fault diagnosis mechanism. Equipped with an illuminated display they show the current sensor temperatures and any kind of warning messages. They are simply installed and adjusted to control the collector circulator or the boiler burner.
