Photovoltaic tile and sloped photovoltaic roof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high transportation and maintenance costs of photovoltaic tiles, along with issues of poor aesthetics and dust accumulation, arise from the differing structures and strengths of tile bases and photovoltaic components, as well as gaps between components during installation.
Innovation Solution
A photovoltaic tile design featuring a base plate with a raising portion and splicing area, allowing for detachable connection of photovoltaic components, which reduces transportation costs and prevents dust accumulation by ensuring flush panel alignment and easy disassembly for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If photovoltaic tiles are transported as assembled units, then installation quality is improved, but transportation costs increase due to special packaging requirements
Solution Approach 1:
The photovoltaic tile system is divided into separate components: a base plate that remains on the roof and a photovoltaic component that can be detached and transported separately. This segmentation allows the photovoltaic component to be transported without special packaging requirements while enabling quality installation through the standardized connecting parts.
2Quantity of substance
If photovoltaic tiles are assembled on-site, then transportation costs are reduced, but construction time increases
Solution Approach 1:
The base plate is prepared in advance and installed on the roof structure before the photovoltaic component arrives. The connecting parts are pre-configured on both the base plate and photovoltaic component, enabling rapid on-site assembly without requiring complex preparation or specialized equipment during installation.
3Shape
If photovoltaic components are tightly fitted to tile bases, then aesthetics are improved, but dust accumulation increases in gaps
Solution Approach 1:
A connecting part serves as an intermediary element between the base plate and photovoltaic component. This connecting part creates a controlled interface that maintains the aesthetic appearance of a tight fit while providing a gap structure that prevents dust accumulation through its design features.
4Stability of the object's composition
If photovoltaic components are permanently fixed to tile bases, then structural stability is improved, but maintenance difficulty increases
Solution Approach 1:
The connection between the base plate and photovoltaic component is made dynamic rather than permanent. The connecting parts enable the photovoltaic component to be securely fixed during operation for structural stability, while allowing for easy detachment and reattachment for maintenance purposes.

AI summary
The present application provides a photovoltaic tile and sloped photovoltaic roof, the tile base comprises a base plate, a raising portion, a splicing area and a first connecting part, the base plate has a first surface and a second surface opposite to each other, the tile base has a first side and a second side opposite to each other, the splicing area is close to the second side, the raising portion is located on the second surface and extends along the first direction, and the raising portion has a first end and a second end opposite to each other along the first direction; photovoltaic component, comprising a photovoltaic panel and a second connecting part, wherein the photovoltaic panel is arranged on the raising portion and is detachable from the tile base through the cooperation between the first connecting part and the second connecting part, wherein the height of the second end of the raising portion relative to the second surface is the same as the thickness of the tile base at the first side. The photovoltaic tiles and photovoltaic roofs of the present application use a raising portion to raise one end of the photovoltaic component so that adjacent photovoltaic panels are flush, which improves the aesthetics of the photovoltaic tiles and also has the effect of preventing dust accumulation.
