6 Frequently Asked Questions about “Drawings required for rooftop solar panel installation”

How do I design a photovoltaic and solar hot water system?

Provide an architectural drawing and riser diagram for the homeowner showing the planned location for future photovoltaic and solar hot water system components. Space requirements and layout for photovoltaic and solar water heating system components should be taken into account early in the design process.

Can solar panels be mounted on a flat roof?

For solar panels on a flat roof, mounting systems are slightly different and can include a triangle 'ballast' box to support the panels. For solar thermal panels (with cells that use the sun's heat to warm water in a house) things are a little different.

Can solar panels be installed on a roof?

"The solar panels will need to be mounted on the roof by installers who understand roofing and will need some scaffold decks to safely get the panels to the roof.

How to install solar panels?

Make space for the solar panel accessories (solar inverter, cables and solar batteries, if desired), for instance in a plant room 4. Plan a day for installation 5. Erect the scaffolding (this can be done by your supplier or by a company you organise) 6. The solar panel mounts will be installed 7. The professionals will install the solar panels 8.

Do you need a solar system diagram?

These drawings should accurately represent the installed elements of the system and should be provided to the homeowner (likely to be used by future solar installer for obtaining a building permit). In addition, the homeowner should be provided with a one-line electrical riser diagram of the PV system components.

What should be included in a PV system drawing?

The drawings should also contain information about the PV array mounting system and identify the specifications for the major equipment including manufacturer, model and installation details.
