Budmat photovoltaic roof structures are a system designed in cooperation between designers and contractors. The design assumptions were adopted based on applicable standards, ensuring quick installation that complies with module manufacturers’ recommendations to meet the highest requirements of the C&I sector.

The system components provide:

• an innovative approach enabling the collection of loads on the
• structure of a given facility
• the option of an individual solution dedicated to the project
• flexibility in the layout of the structure’s rows
• the possibility of preparing a ballast distribution report in the
• form of a design prepared by a Budmat designer
• high resistance class - up to C5
• technical documentation.
