Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If hybrid solar panels are used for co-generation of electricity and heat, then both electricity and heat can be produced, but the overall thermal efficiency and heat transfer characteristics are insufficient
Solution Approach 1:
The panel is divided into distinct functional zones: a photovoltaic layer for electricity generation and a thermal exchange layer with channels for fluid flow. This segmentation allows independent optimization of electrical and thermal performance, with the thermal layer specifically designed to capture and transfer heat efficiently through segmented channels.
Solution Approach 2:
A thermal exchange fluid acts as an intermediary between the solar panel and the heat storage or usage system. The fluid circulates through channels in the thermal layer, absorbing heat from the panel and transporting it to where it is needed, thereby improving overall heat transfer efficiency and reducing thermal losses.
2Reliability
If extensive plumbing is used for feeder pipes and evacuation pipes in hybrid panels, then fluid circulation is achieved, but installation cost and complexity increase significantly
Solution Approach 1:
The thermal exchange channels are integrated directly into the panel structure itself, merging the fluid circulation function with the panel body. This eliminates the need for separate external plumbing systems, as the channels are formed within the panel layers, significantly reducing installation complexity while maintaining reliable fluid circulation.
Solution Approach 2:
The panel structure serves multiple functions: the thermal layer with embedded channels simultaneously provides structural support, heat collection, and fluid circulation pathways. This multi-functionality reduces the need for additional dedicated plumbing components, simplifying the overall system while ensuring reliable fluid flow for heat exchange.
3Use of energy by moving object
If conventional PVT panels are used, then heat and electricity generation are achieved, but installation cost remains high due to extensive plumbing requirements

The panel is divided into distinct functional zones: a photovoltaic layer for electricity generation and a thermal exchange layer with channels for fluid flow. This segmentation allows independent optimization of electrical and thermal performance, with the thermal layer specifically designed to capture and transfer heat efficiently through segmented channels.
Solution Approach 2:
The thermal exchange channels are integrated directly into the panel structure itself, merging the fluid circulation function with the panel body. This eliminates the need for separate external plumbing systems, significantly reducing installation complexity while maintaining reliable fluid circulation.

AI summary
A modular, solar energy system comprising one or more modular solar panels. The solar panels include a pair of general planar, plates that are secured together to form a narrow channel therebetween for the circulation of a liquid. The solar panels have inlet and outlet fluid lines in fluid communication via manifolds with a cold fluid supply line and a warm fluid return line, respectively. The plates are preferably constructed of aluminum and one plate has a photovoltaic cell matrix affixed thereto to face the sun. The plates have dividers or partitions that enhance the heat transfer characteristics with respect to the liquid flowing though the channel between the plates.
