Rooftop array installation

This rooftop solar installation shows an array mounted on a pitched roof and arranged around the existing roof lines. A roof layout should be planned for the structure and site, not forced into a standard panel pattern.

A rooftop installation photographed during mounting. The array is laid out to suit the roof, with fixing points and cable routes agreed before work begins.

Roof work is planned around the weather and around keeping the building usable. Access, fall protection and the route for cables are settled during the site assessment.

Plan the roof before placing panels

A rooftop array begins with a review of the roof shape, orientation, shade and available mounting area. These conditions affect where panels can be placed and how the array can be divided. Existing roof features and safe access need to remain part of the design, rather than being considered after the equipment arrives.

Mounting points and cable routes are agreed before work begins. The inverter and other equipment also need a suitable location with access for inspection and service. Keeping these details in the plan helps coordinate the panel layout with the rest of the electrical installation.

Connect the array to the system

Panel strings, inverter selection, isolation and protection are considered together. The final arrangement depends on the property’s loads and whether the system is intended for grid-tied, hybrid or off-grid use. This page shows the installation type; it does not state a project capacity, product model or performance result.

Panel placement should also leave a workable route for installation and future inspection. If roof repairs are planned, share that before work begins because the mounting plan should not obstruct maintenance. A site visit can confirm conditions that photographs cannot show, such as access restrictions or shade at different times of day. These checks turn an initial layout into a site-specific proposal rather than assuming every pitched roof is alike.

For your own rooftop solar installation, SIDAI can assess the roof and the loads you want to supply before preparing a written specification. Request a site assessment and share any known roof or shading constraints.
