Solar Panel Cadgwith

Preparing a solar panel enquiry in Cadgwith

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: Cadgwith

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.

Roof photographs

Provide clear photographs of the roof faces you want assessed. Include visible chimneys and nearby obstructions, and ask what still needs checking during a site visit.

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.

Outbuildings

If panels on an outbuilding are an option, identify it clearly in the enquiry. Ask how the installer would assess the roof and the electrical connection to the main property.

Scaffolding access

Describe access around the building and any areas that need to remain usable. Confirm whether scaffolding is included and how its installation and removal will be coordinated.

Inverter location

Ask where the inverter would be installed and what access is needed around it. Discuss the proposed position during the survey rather than leaving the decision until installation day.

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.

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.
