The backbone utilizes ORPELAN and ReLA Block modules to create an efficient and lightweight structure. An auxiliary reversible branch mitigates semantic information loss, while the multi-branch ORPELAN enriches the feature space, improving recognition of complex fault shapes. The ADown module adaptively selects downsampling strategies to preserve detailed features and enhance small-scale fault perception.
The ARF-Encoder module integrates attention-scale sequence fusion with re-parameterization. This design tackles channel concatenation redundancy and leverages cross-scale information more effectively, improving multi-scale feature interaction and reducing inference costs. The TFE module specifically enhances detection of small, dense targets, while SSFF integrates multiscale features using a scale-aware mechanism.
The DySample module dynamically upsamples and downsamples features by merging max-pooling and average-pooling with convolution. This mechanism enhances the model's ability to perceive fine-grained features, crucial for small targets and complex backgrounds, preventing blurring and information loss typical of traditional upsampling.

Real-world Deployment Simulation (100 MWp Plant)
A simulation for a 100 MWp photovoltaic power plant (400,000 modules) in Hefei, Anhui Province, demonstrates significant gains. While initial equipment procurement cost is slightly higher, the model's 5% reduction in missed detection rate leads to annual fault loss reduction of 59.5% compared to single-modality. This translates to an overall cost reduction of 56.2% by the 6th year, making the total annual cost 920,000 yuan lower. Furthermore, dual-camera UAVs compatible with Photovoltaic-DETR shorten annual inspection time by 40% (from 20 to 12 days per inspection), streamlining O&M.
