For similar products, it is worth asking:

1. Is it equipped with heat-treated safety solar glass? Smooth glass breaks easily and into shards, danger of accidents!
Is it microprism? It absorbs light better than frosted glass!
Does it have a low metal content, i.e. does it have increased transmittance?

2. On the material of the collector pipes, because the collector with aluminum connecting pipe must not be installed with copper pipes due to corrosion, and plastic five-layer pipes can only withstand heat up to 95 degrees and that is not enough! Copper is really good!

3. Size: each one is around 2.5 m², but it doesn't matter if it's 2.3 or 2.5!

4. The absorber surface: chemically applied, e.g. black chrome selective coating or just plain painted matte black?

Packaging size of the solar collector: 205 x 135 x 12 cm 34 kg

Don't forget to choose a support frame! SID support frames can be selected for these flat collectors.
With copper collector pipe, heat-treated safety microprism blue glass (Blue Chrome), aluminum housing, thick insulation for solar energy utilization.
Harp system COPPER collector tube design, with 22 mm connection sockets.
It has a CE certificate and SOLAR KEYMARK certification.
Reliability, operational safety and longevity are guaranteed by high-quality, corrosion-resistant raw materials and sophisticated Italian production. Among others, safety microprism solar glass with a low metal content (it has excellent heat resistance and a high degree of chemical resistance) and copper.

The solar collector support frame accessory is not included in the price, it can also be ordered for pitched and flat roofs, see our products.
