Technical knowledge for better PV plant decisions.
Practical guidance and research interpretation for EPCs, plant owners, asset managers and O&M teams working with commercial and utility-scale PV.
Technical Guides
Evergreen answers to technical questions arising during handover, operation, underperformance investigation and cleaning strategy review.
When should a PV plant health assessment be commissioned?
Handover, acquisition and underperformance create different questions—and different evidence needs.
From low output to an actionable diagnosis
A structured way to separate availability, curtailment, equipment, environmental and data-quality pathways.
Why cleaning frequency should follow soiling loss
How weather, yield recovery and full operating cost fit into a defensible cleaning decision.
When should a solar farm be cleaned?
How rainfall, dust and plant data can support a cost-aware cleaning decision—and where model assumptions need local validation.
