As of 13 August 2026, AI can compare solar panel installation quotes.
This still needs a person who signs their name to it.

What the alternative costsThe available tool data gives no price for a solar quote comparison service.
If this goes wrong: you choose a cheaper-looking quote that leaves out important work or equipment and pay to correct the decision later.
What to actually do
Hand it to a person
The route this page recommends
A person who owns the outcome does this end to end, worth it when the failure is dear.

The distant thirdA chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.
How to actually do it
- Open each quote and gather the full written offer, including attachments, equipment schedules, terms, exclusions, warranties, payment stages and any survey notes.
- Record your recent electricity usage, roof orientation if known, shading, any planned roof work, whether you want a battery and the outcome you care about, such as lower bills or backup power.
- Paste the property details and every quote into a chatbot using the comparison prompt, keeping each quote under a clearly labelled heading.
- Ask the chatbot to produce a like-for-like table and separate stated facts from items that are missing, assumed or unclear.
- Compare the table against the original quote documents, checking every price, item, warranty, exclusion and payment stage before relying on it.
- Send the chatbot's unanswered-question list to each installer and ask them to confirm the responses in writing, including equipment, structural or electrical work, warranties and what is excluded.
- Choose only after comparing the revised written offers and, where the technical suitability or installer credentials remain unclear, speak to an experienced solar installer.
Prompt
Compare the solar installation quotes pasted below for a UK home. Do not invent missing facts, prices, savings, generation figures or technical conclusions. First create a like-for-like table covering total price, VAT if stated, number and stated output of panels, panel brand and model, inverter brand and model, battery details, scaffolding, electrical work, roof work, monitoring, export-meter or grid work, warranties, installation timetable, payment stages, certification or accreditation claims, exclusions and aftercare. Mark every item as included, excluded, unclear or not mentioned, and quote the relevant wording from each offer where useful. Then identify which differences could materially affect value or suitability. List the exact questions I should send to each installer before choosing. Do not recommend a quote solely because it is cheapest, and do not decide whether my roof or electrical system is suitable. End with a comparison-based provisional view, clearly labelled as not professional advice, and state what an installer must confirm in writing. My home and requirements: [insert relevant property details, electricity use, roof information, battery preference and budget]. Quote A: [paste full quote]. Quote B: [paste full quote]. Quote C: [paste full quote].
Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.
What it gets wrong
- AI cannot inspect your roof, identify shading or assess the condition of the existing electrical installation.
- AI cannot prove that an installer's predicted generation, savings or payback is realistic for your property.
- AI cannot tell from a quote alone whether a warranty will be useful in practice or whether the installer will honour it.
- AI cannot negotiate missing work or obtain binding written commitments from installers.
- The final choice and the consequences of an unsuitable installation remain yours.
Even on a YES, the friction has a name: verification cost, stakes of error and context depth.
How we scored this
Five axes, each scored nought to two by hand: ten means AI carries the task cleanly, and the thresholds that turn a total into YES, PARTLY or NO are published in the methodology. Each axis name links to its definition.
| Axis | Score (0–2) |
|---|---|
| Output | 2 |
| Inputs | 2 |
| Verification | 1 |
| Liability | 1 |
| Effort delta | 2 |
| Total | 8 / 10 |

FAQ
- Can ChatGPT compare solar panel quotes?
- Yes. It can extract the main differences between quotes, flag exclusions and produce questions for the installers, provided you supply the complete documents. It cannot inspect your property or validate technical claims.
- What should I compare in solar panel quotes?
- Compare the full price and included work, panel and inverter models, battery details, warranties, payment stages, exclusions and aftercare. Also check which assumptions the installer has made about your roof, electricity use and expected output.
- Can AI tell me which solar quote is best?
- It can identify which offer appears more complete or better aligned with the information you provide. It cannot safely decide whether the design is suitable for your roof or electrical system, so get unresolved technical points confirmed by the installer.
- Is it safe to use AI to choose a solar installer?
- Use AI to organise the evidence and prepare questions, not as proof that an installer or design is suitable. This is not professional advice, and a serious or technically unclear case needs an experienced solar installer to check the proposal.
