A single quote says little as long as you have nothing to compare it with. Only the comparison of multiple quotes shows whether price, performance and components are right. This page explains what a good photovoltaic quote should contain, how to assess items and why quotes for the same roof can differ.
Key points at a glance
The key points of this section can be summarised compactly:
- A complete quote clearly lists technical specifications, cost items, warranties and services.
- Quotes differ because components, scope and service vary – price is not the only factor that matters.
- Mehrere Angebote schaffen den nötigen Vergleichsmassstab.
- Via solar-guide.ch you receive individual quotes from suitable specialist installers and compare them yourself.
- You conclude the contract directly with the chosen specialist partner.
The comparison is worthwhile because only multiple quotes show whether price, components and scope of services match.

Why is a single quote often not enough?
Without comparison, there is no benchmark. An offer may appear attractive at first glance, but only when placed alongside other quotes does it become clear whether components, warranties and included work are reasonable. Therefore, it is common and sensible to obtain several offers and compare them item by item.
What should a photovoltaic quote include?
The following table lists the key points for what should be included in a photovoltaic quote:
| Area | Content |
|---|---|
| Technical specifications | System output (kWp), number and type of modules, inverter, storage |
| Cost items | Modules, inverter, substructure, scaffolding, electrical work, planning |
| Additional components | Storage, energy management, wallbox |
| Services | Installation, connection, registration with the grid operator, commissioning |
| Warranties and service | Product and performance warranties, maintenance |
| Subsidies | Note on one-off payment and regional programmes |
| Price | Total price including VAT |
If this information is missing, it is difficult to assess whether the quote is complete or merely appears cheap at first glance.
Which technical details should be included in the quote?
Pay attention to the system output in kilowatt-peak, the number and type of modules, the inverter and – if planned – the capacity and power of the storage. These details determine yield and quality and are the basis for a fair comparison.
Which cost items should you understand?
A good quote presents costs in a comprehensible manner, rather than just naming a lump sum. This allows you to see whether scaffolding, electrical work and registration are included. These items are a frequent source of price differences:
| Position | What to look out for |
|---|---|
| Modules and inverter | Type, quality, warranty period |
| Mounting structure and scaffolding | Included or separate? |
| Electrical work | Scope, adjustments to the distribution board |
| Storage | Capacity, output, backup power option |
| Planning and application | Who covers what? |
| Total price | Including VAT and all services |
For a reliable assessment, these points should always be considered together with location, consumption and specific quote.
How are battery storage, wallbox and energy management offered?
If storage, a wallbox or an energy management system are part of the offer, they should be listed individually with their technical data and prices. For storage, it is important whether a backup power or emergency power function is included – this is not automatically provided. More on this on the Photovoltaic system with storage page.
Which guarantees, services and maintenance are important?
Compare not only prices, but also warranties and service offerings: How long do product and performance warranties last? Is maintenance included? Who is the point of contact in case of faults? Such points influence the value of a quote over the years.
How should subsidies and feed-in remuneration appear in the quote?
A serious quote refers to the one-off payment and any regional programmes. Details on the subsidy can be found on the page What does a solar system for a single-family home cost. How feed-in electricity is remunerated is relevant in the context of economic viability, but it is not a component guaranteed by the system itself.
Why do quotes vary?
Because every roof is different and providers calculate different components, scopes and warranties. A lower price may be due to a smaller scope of performance or simpler components. Therefore, the comparison position by position is more important than looking at the final sum.
What warning signs are there in quotes?
You should ask particularly detailed questions about these points before accepting a quote:
| Warning signal | Why critical |
|---|---|
| Only a lump sum, no line items | Comparison hardly possible |
| Scaffolding or electrical work not mentioned | Subsequent additional costs possible |
| No information on warranties | Value over the years unclear |
| Pressure for a quick conclusion | No room for a fair comparison |
| Unrealistic yield or savings promises | Unreliable assessment |
This makes it easier to see quickly whether a quote is complete, comparable and plausibly structured.
How do you recognise a good quote?
A good quote is specific, complete and structured in a way that allows it to remain comparable with other offers:
- System output, number of modules and module type are specified.
- The inverter and any battery storage are specified.
- Scaffolding, electrical work and registration are included or clearly specified.
- Warranties and service are described.
- The total price is stated inclusive of value added tax.
This makes it easier to see quickly whether a quote is complete, comparable and plausibly structured.
solar-guide.ch recommends: Obtain at least two to three quotes and ensure that they all cover the same scope of services – only then are they comparable. solar-guide.ch forwards your request to suitable specialist installers; you then check and compare the offers yourself, and conclude the contract directly with the chosen specialist partner.
How do you receive quotes via solar-guide.ch?
Instead of contacting multiple operators individually, submit a single request via solar-guide.ch. It will be forwarded to suitable specialist installers in your region. You will receive individual quotes and can compare prices, services, components, and warranties at your leisure. Further assistance can be found under Compare quotes and in the seven key points for comparing quotes. Find regional specialist installers via the page Photovoltaics nearby.
Conclusion
A good quote is transparent, complete and comparable. The real added value arises when comparing multiple quotes: only then can you determine which offer is suitable for your building.
With solar-guide.ch, you can submit your request for free and without obligation. Your request will be forwarded to a maximum of three suitable specialist installers in your region. This allows you to receive individual quotes and compare them at your leisure.

Frequently asked questions and answers
How do I get a quote for a photovoltaic system?
Via solar-guide.ch, you submit a free, non-binding request. This is forwarded to up to three suitable specialist installers from your region, who will create individual quotes for you.
What must be included in a PV quote?
System output, number and type of modules, inverter, any battery storage, included work (incl. scaffolding and electrical work), warranties, notes on subsidies, and the total price including value added tax.
Why should I compare multiple quotes?
Because quotes differ in components, scope, guarantees, and price. Only a comparison shows which quote is appropriate for your building.
Is a quote binding?
A quote is an offer; it becomes binding with the conditions stated therein and your consent. Clarify the validity period and included services before placing the order.
Who is my contractual partner?
You sign the contract directly with the specialist installer of your choice. solar-guide.ch facilitates the contact but is not a party to the installation contract.
