IntroductionSunstar Panel

SUNSTAR solar collectors is one of the worlds most reliable collector used for solar water heating.


Sunstar Unique Features

Over-molding Injection Technology

One of a kind injection process connects riser tubes to the manifold header, creating a single polymer panel with no leaks.

Square Manifold Header

Unique square design that assures tight fastening and mounting of the panel on any roof type.

Innovative Engineering

A combination of special header and mounting features eliminates possible tile damage caused by constant contraction and expansion of the materials, while preserving flow characteristics with minimum pressure drop.

Sunstar Panel Module

Individual Tube Design

Minimizes wind effects on the panel and creates extreme mechanical stability.

Specially Formulated Polymer Material

As tested in authorised laboratories, a unique polymer formula stabalises against sustained ultraviolet radiation, extreme weather and aging.

Spacer Bars

Prevent warping of the panel over time, as well as prevents abrasion of the riser tubes due to thermal expansion of the panel.

Modular Structure

Enables fast and firm connection between panels, creating any size absorption area over any type of roof imaginable.

Parts & Fittings

All-Polymer parts, creating simple connection between panels and standard plumbing pipes.

chemical resistance

The polymer, polypropylene material is higly durable against:

  • Corrosion & lime scaling.
  • Chlorine, Bromine, Iodine, HCL and other swimming pool chemicals / disinfectants.
  • Salts & Sea Water.

Potable Water & foodstuffs contact certification

Polypropylene is certified for use with potable water, as specified in the US standard NSF-61, German standard DVGW-W270, and for foodstuffs contact as specifies in the Swiss standard KsV-817041 and the British Standard SI2000-3162.

SUnstar components

Every component of a Sunstar System is manufactured from the same polypropolene material used

Unlike other solar pool heating systems, Sunstar doesn't require metal clamps or rubber hoses, that will deteriorate eventualy with use or need tightening / adjustment each year, as part of its installation. Heliocol components require zero maintenace.
