4 Frequently Asked Questions about “Requirements for installing photovoltaic panels on building surfaces - Inala Strategic Solar”
What are building codes for solar panel installation?
Building codes for solar panel installation are crucial for ensuring the safety, efficiency, and longevity of solar energy systems. These codes, which encompass structural, electrical, fire safety, and zoning regulations, provide a comprehensive framework for the proper design, installation, and maintenance of solar photovoltaic (PV) systems.
Should solar energy be included in New construction policies?
Governments around the world are increasingly incorporating solar energy requirements into building policies. In 2025, a growing number of jurisdictions mandate or incentivize the inclusion of solar photovoltaic (PV) systems in new construction.
How high can a PV system be installed on a roof?
PV system installed on roof should not exceed 2.5m high. PV system exceeding the height of 1.5m should be certified by an Authorized Person who is registered under the Buildings Ordinance for submission of a safety certificate to the Lands Department for record. The average imposed load should not exceed 150kg/m 2.
Does a new home need a solar PV system?
Under state Building Energy Efficiency Standards, any new residential construction up to three stories tall must include a solar PV system sized to meet a portion of the home's expected energy use. This rule took effect in 2020, making solar energy a standard feature of new single-family homes and low-rise apartments.
