« The great experience of Janus Energy in the heat generation sector created high-quality, high-performance products like Sunnyday, the unglazed polypropylene solar panel, and Sundrop, the natural circulation system for sanitary hot water »

Operating in the field of alternative energies, Janus Energy has been designing, developing and installing sanitary hot water and swimming pool water production systems for over 25 years. Its range of products is very varied: from solar showers to photovoltaic and solar panels. In the solar heat sector, in particular, Janus Energy proposes the unglazed polypropylene solar panel Sunnyday, an extremely functional solution both in seasonal, from May to September included, and annual applications. The great experience of the company in the heat generation sector is based on the work of qualified professional installers, who can offer expert advice on the most appropriate solar thermal system for each situation and user requirement, always with the objective of ensuring top energy-efficiency and convenience. SUNNYDAY ‘ON THE ROCKS’: NO MORE FROST DAMAGE Non-glazed panels are solar collectors made with plastic materials (such as PVC, polypropylene, neoprene or synthetic rubbers), with no insulation and glass covers. For these features, they are also known as “plastic” or “unglazed” collectors. They are the ideal solution when slightly higher than ambient water temperatures are required. One of the most interesting applications for unglazed collectors is the heating of outdoor swimming pool water: here they provide a perfect solution to maintain a pleasant water temperature (25-28 °C) in small and large size swimming pools. These collectors can also be used to heat sanitary water (35-40 °C) in second homes that are used only in the summer or holiday accommodation facilities such as

hotels, camping sites and bathhouses, which are all mostly used in warm weather periods. The issues of winter maintenance to protect solar panels from winter frost are wellknown. However, this problem has been definitively resolved recently by our Sunnyday ‘On the rocks’ solar panel (Sunnyday SF), which ensures the same performance of the conventional panel (Sunnyday SD), but has a special flattened shape of the channels (5.5 mm wide) that allows them to absorb the expansion due to frozen water without breaking. Sunnyday is built with a particularly robust copolymer polypropylene mix, compatible with food uses and resistant to aggressive chemicals. These features allow water to be directly heated inside the panel, whether it is sanitary water or a swimming pool water, with considerable benefits in terms of simplicity, cost and efficiency of the system. Any support base is indicated for its installation, provided there is no roughness which would damage the panels, also due to the abrasion caused by the small movements due to thermal expansion and vibration induced by the wind. The new-profile Sunnyday SF series solar panel has been certified by Eurofins according to the UNI EN 12975-1 standard, which assesses its compliance with duSUNDROP, A NATURAL CIRCULATION KIT Sundrop is a natural circulation system for sanitary hot water, to be installed on terraces or roof terraces. It is an excellent solution for second homes and summer tourist facilities, and consists of: → A 200 l stainless steel corrosion-resistant tank that required no maintenance and no heat exchangers; → 3 Sunnyday SF Series 2000 solar panels that ensure no overheating, no scaling, no corrosion, no frost damage, no glass barriers. Moreover, these panels are more efficient than glass panels in the summer period. Sundrop is a synonym of simplicity, technology, and reliability. Having neither a thermal probe nor requiring any electronic adjustment, it only works based on the laws of physics, i.e. difference between the temperature of the water contained in the panels and that contained in the tank. Due to the properties of polypropylene, Sunnyday is a clean and efficient solar panel system: the sanitary water that passes through them remains clean, drinkable, and with no scale build up.
