A solar shortlist should reduce irrelevant choice while keeping companies that could genuinely meet the brief. It should not reward a large panel bundle for a small plug-in request or reject a national service simply because its office is far away. These fictional examples show the questions to use when assessing your options.
A useful shortlist reflects the request. A famous supplier, nearby office or low headline price cannot make an unsuitable product fit.
Examples, not customer case studies
The households below are fictional decision exercises. They are not completed installations, live quotations or evidence of savings. Their purpose is to show what questions should separate a plausible offer from a poor match.
For each one, start with requirements that cannot be traded away, then compare price and service among plausible options. This is our suggested buying approach, not a promise that every unknown about a property can be resolved by an online form.
A tenant seeking a small balcony setup
This household wants a solar-only plug-in device, has limited usable space and has not yet obtained building permission. A plausible shortlist would focus on the correct connection route and a configuration that could fit, with permission unresolved before purchase.
A large hardwired roof bundle would not become a good match because it offers more watts per pound. The immediate next step is a specific permission request and mounting assessment, not increasing the panel count. Energy Saving Trust covers these building and installation checks.
An owner comparing garden options
This household wants a compact setup in a garden and values a low complete cost. One seller offers a lower kit price but leaves mounting and delivery unpriced. Another gives an itemised offer for the selected configuration. The first cannot yet be declared cheaper.
A national supplier should remain a candidate when it serves the address. A nearby office may be convenient, but it does not answer whether the company supplies this type of kit or will undertake the work. Ask about the actual service area and scope.
An owner who wants a managed installation
This household wants design, fitting and ongoing support through one contract. Supply-only offers should not be presented as equivalent to an installed proposal. The comparison should separate equipment, labour, connection responsibilities and after-sales cover.
RECC advises obtaining a written, itemised quotation and property-specific performance estimate for an installation. Use those documents to compare plausible suppliers, then confirm unresolved details before accepting. More names are not automatically more choice if none answers the brief.
A solar shortlist starts with the requirement, not the brand
Treat this matrix as a way to review the examples, not a live ranking or endorsement. After establishing a plausible fit, compare complete price and service evidence. Keep unresolved details visible and ask the supplier to settle them. A famous name does not fill a missing specification, just as a nearby address does not establish coverage.
| Household brief | Keep in consideration | Do not mistake for a match |
|---|---|---|
| Tenant with a small balcony | A fitting configuration, subject to permissions and safe mounting. | A large hardwired roof bundle. |
| Owner seeking a compact garden kit | Relevant kits delivered to the address with suitable mounting. | An office address without evidence of the offered service. |
| Owner wanting a managed project | A complete proposal with agreed design, fitting and support. | A supply-only headline price. |
Common questions
Should a nearby installer always come first?
No. Relevant services and coverage of the address matter before office proximity. A remote registered office can belong to a business with strong local operations, while a nearby company may not offer the requested route. Ask where the work is provided, not just where post is received. How to compare solar installation quotes fairly.
Should I discard every option with an unanswered question?
Not necessarily. An unanswered delivery date is different from a product that cannot meet an essential requirement. Keep a plausible candidate while you resolve material uncertainties, but do not commit money on an assumption. The comparison should make those differences easier to understand.
