Home / Evacuated Tube Solar Collectors / CPC Evacuated Tube Solar Collector
A modular solar thermal collector combining evacuated tubes, a heat-transfer manifold and compound parabolic reflectors to capture direct and diffuse solar radiation for hot-water and supplementary-heating systems.
This distinction matters for engineering, quotations and SEO. A CPC collector supplies captured thermal energy to a designed system; it does not store or deliver domestic hot water by itself.
A weather-resistant shaped reflector is positioned behind each evacuated tube to redirect solar radiation that would otherwise pass between tubes or arrive at less favourable angles.
Direct and diffuse sunlight reaches the collector across changing incidence angles.
The reflector geometry sends additional radiation toward the tube absorber surface.
The evacuated space insulates the selective absorber and reduces convective heat loss.
The selected heat-transfer architecture moves collected energy into the external solar circuit.
Double-wall borosilicate tubes protect the selective absorber within a vacuum-insulated space.
Reduced environmental heat lossShaped reflective surfaces recover radiation from the gaps and redirect it toward the absorber.
Improved use of collector footprintHeat-pipe, U-pipe or direct-flow architectures may be developed as separate configurations.
System-specific hydraulic designThe header gathers heat from the tube array and connects the module to the external circuit.
Centralized collector connectionA structural frame supports the tube, reflector and manifold assembly for roof or rack mounting.
Repeatable array installationSelected designs allow individual tube or reflector service without replacing the complete array.
Lower service-part burdenThe collector array must be hydraulically and thermally matched to the storage volume, load profile, climate, heat exchanger and backup source.

Technical and purchasing questions about CPC collector modules and their use in complete solar thermal systems.
No. It is a collector module. The storage tank, pump station, controller, heat exchanger and safety components are designed separately.
The compound parabolic reflector redirects additional direct and diffuse radiation toward the evacuated-tube absorber, including light that would otherwise fall between tubes.
Selection is based on aperture area and tested performance together with climate, load temperature, daily energy demand, storage, roof area and system losses—not tank litres.
Yes, subject to model-specific pressure drop, permitted series length, flow balancing, pipe sizing and control design. The final array must be engineered.
A suitable closed-loop water-glycol design may be considered, but freeze protection depends on the entire system, fluid concentration, controls and installation details.
No. They are different heat-transfer architectures with different hydraulic and service characteristics. The exact Cassky configuration must be identified in the model datasheet.
Potential options include module size, tube count, transfer architecture, reflector, manifold, connections, frame, labeling, manuals and packaging, subject to engineering and order terms.
