Solar Panel Knockando

Preparing a solar panel enquiry in Knockando

Gather a recent electricity bill and think about when your household uses power. Daytime use, evening use and plans for an electric vehicle can lead to different discussions about system design. Tell the installer whether the enquiry is for panels alone or includes a battery, and distinguish current needs from possible future changes.

A roof-specific design matters

A solar proposal should be based on the roof available, its orientation, shading and condition. Ask how the proposed panel layout was chosen and whether the installer needs to inspect the roof before finalising the offer. Neighbouring trees, chimneys and other obstructions should be assessed at the property; a location name alone cannot establish the likely output.

Look beyond the number of panels

Compare the proposed panel capacity, inverter, mounting arrangement and any battery specification. Ask what is included for scaffolding, cabling and electrical work. If two offers recommend different system sizes, ask each installer to explain the reason before comparing their totals. Keep product warranties separate from the installation workmanship guarantee when reviewing the paperwork.

Understand the assumptions in an estimate

Ask for the assumptions behind predicted generation and household savings, including how much electricity the household is expected to use directly. A projection is not a guaranteed return. Discuss monitoring, handover documents and the point of contact if the system reports a fault. If a battery is proposed, ask how its usable capacity and controls relate to your actual pattern of electricity use.

Preparing your solar panel brief: Knockando

Use the points below where they apply to your project. They are questions to discuss with a company, not assumptions about your property or the local area.

Daytime electricity use

Tell the installer which appliances normally run during daylight hours. Ask how the proposed system relates to that usage instead of relying only on your annual electricity total.

Existing roof work

If roof repairs are already planned, tell the solar installer before agreeing an installation date. Discuss the sequence of work and which contractor is responsible for each stage.

Battery scope

If a battery is included, ask for its usable capacity and an explanation of the controls. Keep the battery price distinct so you can understand what it adds to the proposal.

Monitoring access

Ask how you will view generation and system status after handover. Confirm what equipment or internet connection is needed and who can help if the monitoring stops working.

Cabling routes

Discuss where cables would run and how visible routes will be finished. If there are rooms or external features you want to avoid disturbing, identify them before the final quotation.

Comparing projections

Request the assumptions behind each generation estimate. If the figures differ noticeably, ask whether the difference comes from system size, roof layout or the assumptions used in the calculation.

Aftercare contacts

Find out who handles a fault enquiry after installation. Ask how responsibility is divided between the installer and equipment manufacturer, and keep the relevant contact details with the handover documents.

Commissioning information

At handover, ask the installer to explain normal operation and the information shown by the monitoring system. Keep the final equipment list and installation documents together for future reference.
