Solar Installation Quote Template
System size in kW DC, module and inverter models, production estimate, interconnection. Free PDF, no sign-up.
A solar quote is the most-compared document in home improvement: the buyer will put three of them side by side and look for the price per watt. That comparison only works if the document says what it is comparing — module model, inverter type, system size in kW DC and a production estimate with its assumptions. All of that is known before installation, which is why the price can bind, and why vagueness in a solar quote reads as evasion rather than as brevity.

What this quote commits you to
- How long it stands
- 30 days, at the module and inverter models named; a supply change after that window is re-quoted at the new equipment cost.
- What it does not cover
- Main panel upgrades, roof repair or re-covering before mount, charges the utility levies for interconnection, HOA applications, and tree trimming for shade.
- What would change the price
- A structural review that calls for rafter reinforcement, or a condition the utility adds while reviewing the interconnection application.
- How the client accepts it
- Sign the quote and the interconnection authorisation together; the utility application cannot be filed without both of them.

What to put on a solar installation quote
- System size in kW DC and the resulting price per watt, stated rather than left to arithmetic
- Module and inverter by manufacturer and model, with the microinverter or optimiser named
- Annual production estimate in kWh, and the tool and shading assumptions behind it
- Racking and attachment method, and the flashing used at each penetration
- Roof condition assessment, and the remaining life the design assumes
- Interconnection application, permitting and inspection as their own lines
- Which incentives are applied on this document and which the buyer claims themselves
Questions
Should an incentive the buyer claims be shown as a discount?
No. A rebate or credit the buyer applies for themselves is not money you are taking off your price, and netting it off makes your quote look cheaper while promising a benefit you do not control. Show the gross price, and name the programme and who files it separately.
What makes a production estimate credible?
Naming the tool, the tilt and azimuth, and the shading survey it used. A number with no method behind it is a marketing figure, and a buyer comparing three quotes will treat it that way.
Who is responsible if the utility adds an interconnection condition?
Say so on the quote. Utilities do add requirements during review — a transformer upgrade, a specific disconnect — and that is a price change nobody can foresee, which is exactly why it belongs in the terms rather than in a phone call later.
About the free quote generator
Is this quote generator really free?
Yes. There is no fee, no trial period and no watermark on the PDF. Nothing on this page requires a credit card.
What is the difference between a quote and an estimate?
A quote is a fixed price you are offering to hold, and it is binding on you once the client accepts it. An estimate is your best projection of the cost and can move if the job does. If the scope is not settled yet, send an estimate instead.
Is a quote legally binding?
Once a client accepts it within the period it stands, a quote generally forms a contract at that price — the details depend on your jurisdiction and on what the document itself says. That is why the price, the scope and the exclusions all belong in writing, and why the document prints the date the offer expires.
How long should a quote be valid until?
Thirty days is the common default, and two weeks is sensible when materials prices are moving. Whatever you choose, state it on the quote: an offer with no expiry is an offer you have made for ever.
Can I raise the price after the client accepts?
Not unilaterally, which is the point of quoting rather than estimating. What you can do is price the variations the client asks for afterwards, provided the quote said what was and was not included.
Do I need to create an account?
No. Fill in the form and download the PDF directly — there is no sign-up and no login for this tool.
Can the client accept the quote online?
Not from a downloaded PDF. Saving the quote to an account gives it a link the client opens and answers on, and the acceptance is recorded against the document rather than living in an email thread.
Can I use this for any currency or country?
Yes. Choose any currency and country for either party — the totals and formatting follow your selection.
