01 / YOUR HOME

A few choices.
A clearer picture.

Choose a roof to explore. These choices change this guide only—not your order or approved design.

What is your main roof?

Not sure, or have a mixed roof? Your site survey confirms each roof area.

What is included in your system?

Solar panels and an inverter are shown throughout. Optional equipment is not included unless it is in your signed proposal.

04 / HOW THE PANELS ARE FIXED

A tiled roof.
Carefully lifted. Carefully refitted.

The fixing depends on the roof. We refit tiles around the mounts, choose fixings to suit the metal roof profile, or use supports designed for a flat concrete roof.

ROOF DETAIL / INDICATIVE · NOT FOR CONSTRUCTION
What happens if the roof needs repair?

Before installation: Please document and tell us about known leaks, cracked or worn tiles, and other existing roof issues. Share dated photos or notes where available. Please don’t climb onto the roof.

Existing roof repairs: You arrange and pay for repairs to pre-existing roof issues. These repairs are not part of Sunollo’s solar installation. If repairs are needed for safe installation, we’ll wait until they’re complete before working on that part of the roof.

Installation cover: Sunollo’s installation cover does not extend to leaks or damage caused by pre-existing roof issues. Our responsibilities for damage caused by our work are unchanged.

05 / THE ROUTE THROUGH YOUR HOME

Follow one route.
Understand the whole system.

Solar wiring leaves the roof in protective casing, reaches the inverter, then connects to your home’s electrical board through the required protection.

01 / ROOF TO INVERTER

Protected DC cabling

Cables are supported and protected from weather and damage. Roof and wall entries are finished with the appropriate sealing details.

02 / INVERTER TO HOME

A dedicated AC connection

The electrician provides the required cables, isolators, breakers and protection, then connects to the approved point at your board.

03 / SAFE AND IDENTIFIABLE

Earthing, separation and labels

Metalwork is bonded as designed. DC, AC and communication routes are separated appropriately and labelled for future servicing.

06 / THE EQUIPMENT YOU WILL SEE

Considered locations.
A considered finish.

Equipment belongs in an accessible, suitable place—not wherever a cable happens to end. The exact model sets the mounting method, clearances and appearance.

IN EVERY SOLAR SYSTEM

The inverter

Converts solar DC power into AC power for your home. It may be wall-mounted or part of an integrated energy system.

  • Location agreed before drilling or fixing
  • Ventilation and service access kept clear
  • Protective devices and cable casing finished neatly
  • Monitoring connected and demonstrated where included

Generic outline—not a product photograph. Final size, colour and layout follow your selected model.

YOUR INSTALLATION VISITS

How the visits usually unfold.

Estimated on-site work: 2 days to 1 week.*

  1. Confirm the plan

    We discuss tentative dates and agree the panel layout, cable route, equipment locations and safe access during your sales visit or later, before installation.

  2. Set up and install

    Please clear the agreed access area. The crew sets up safely, then fits the panels, cables and equipment.

  3. Test before switch-on

    The assigned LEW (Licensed Electrical Worker) coordinates testing and any required SP inspection.

  4. Show you how it works

    We explain how to use the system and share your documents and support contacts.

07 / THE PEOPLE AT YOUR HOME

One coordinated team.

Sunollo coordinates the work from planning to handover.

Project Manager

Your main point of contact. Confirms the plan, dates and next steps.

Installer Supervisor

Leads the crew on site and checks that the work follows the agreed plan.

Delivery Head

Oversees delivery and steps in when an issue needs more than one team to resolve.

Licensed Electrical Worker

Tests the system and coordinates any required SP inspection and switch-on.

One shared project record.

Sunollo keeps project updates, decisions and support requests in one shared system. The team can pick up where things left off, so you don’t have to chase individual WhatsApp threads or repeat yourself.

Submit a support request or view your open tickets at support.sunollo.com.

08 / BEFORE WE CALL IT COMPLETE

Installed is not the same
as ready to use.

Physical installation, electrical checks, SP clearance and export payments are different steps. Your team explains which are complete and what remains.

01

The work is checked

Roof finish, fixing, visible sealing, cable support, equipment and labels are inspected. Electrical tests are recorded by the responsible professionals.

02

The system is authorised

The assigned LEW coordinates the applicable SP inspection and turn-on process. Do not switch on the system yourself.

03

You are shown how it works

Understand the app where included, normal operation, safe shutdown instructions and who to contact. Do not open equipment or electrical covers.

04

You receive the handover pack

Keep the as-built layout and wiring drawings, model / serial details, test records, approval records, operating guides and warranty contacts.

Keep the permit dates separate.

Use the permit guide for CS1, PV1, CS5, SP inspection and the separate MOC / NER steps.
