Structural gutter system for solar panel array
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Solar panel arrays installed in urban areas face challenges in managing rain, snow, and ice accumulation, which can lead to structural loading issues and safety concerns, particularly when installed over parking lots, requiring effective drainage systems to prevent damage and injury.
Innovation Solution
The implementation of a solar canopy system with angled solar panels and a gutter system that collects and directs precipitation away from the structure, utilizing gutters at both lower and upper meeting points of the panels, and a pipe system to discharge water to the ground, reducing wind loads and supporting the structure with lighter materials like cold-rolled steel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If solar panels are installed at an angle to generate energy, then energy generation is improved, but precipitation accumulation and structural loading issues worsen
Solution Approach 1:
The gutter system is divided into multiple segments including upper gutters at the apex, lower gutters at the eaves, and intermediate gutters, allowing precipitation to be collected at different locations along the panel array and redirected to appropriate discharge points
Solution Approach 2:
Gutters serve as intermediary components that intercept precipitation running off the solar panels and redirect it through downspouts to ground-level discharge points, preventing ice and snow from falling directly onto vehicles or pedestrians below
2Strength
If traditional support structures are used, then structural strength is improved, but construction costs and weight increase
Solution Approach 1:
The gutter system performs multiple functions: it collects precipitation, provides structural support for the solar panels, and acts as a roofing element, eliminating the need for separate purlins and reducing overall construction costs
Solution Approach 2:
The system integrates gutters made from materials like aluminum, vinyl, copper, or stainless steel with the solar panel mounting structure, creating a composite system that reduces weight while maintaining structural integrity
3Adaptability or versatility
If solar panels are installed over parking lots, then land use efficiency is improved, but safety concerns from falling ice and snow worsen
Solution Approach 1:
Gutters and downspouts act as intermediary structures that capture precipitation before it can fall from the solar panels, channeling it safely to ground-level discharge points away from vehicles and pedestrians
Solution Approach 2:
The harmful precipitation is extracted from the system by capturing it in gutters and removing it through downspouts to ground-level discharge points, preventing it from falling onto the parking area below

AI summary
A system for collecting precipitation falling on a solar canopy structure. The solar panels arranged in rows. Each row is tilted increasing sun exposure for solar energy collection. The rows are arranged such that two rows face each other forming a V-shape. Pairs of rows tilted towards each other are arranged together. A gutter is installed at the bottom of each “V” formed by two rows. The gutters collect precipitation, such as rain, snow, and ice that runs off of the solar panels. The gutter system collects the precipitation from each gutter and delivers the precipitation to the ground system. Various means are used for preventing precipitation from falling between the upper meeting point of two rows that meet on the higher side, including gaskets and additional gutters.
