Early-Stage
Overview
Explore expert BioSolar guidance covering design, installation, maintenance and best practice to help you deliver efficient, compliant and long-lasting commercial systems.
EARLY-STAGE DESIGN OVERVIEW
At concept stage, biosolar design is still flexible — early coordination helps the roof perform as one integrated system.
At concept stage, the layout, access routes, and structural strategy are still flexible, so it’s the best time to make key decisions. Early coordination helps integrate the green roof build-up, PV array, mounting approach, and drainage strategy so the roof works as one complete system.
This stage is where you should confirm the main “roof rules”, such as:
-
Where PV can sit without access or shading issues
-
Where planting needs to go for ecology and drainage
-
Where maintenance routes are needed for safe long-term access
-
How water will drain without ponding or blocked outlets
