Website Design in Utah: A Solar Savings Calculator That Agrees With the Disclosure Statement

Updated November 2026 · Written and maintained by the Progression Agency strategy team

A homeowner types a power bill into a solar retailer’s homepage and sees decades of savings. Then the paper disclosure statement arrives, and Utah Code 13-52 has capped its assumed rate increase at 3% a year and made it list every assumption behind the number. When the website promised more than the paper, the sale starts with a question. Website design in Utah for a solar retailer builds the calculator from the same assumptions the statute names, so both say the same thing. Progression is a New York team that builds for Utah retailers remotely, with on-site working sessions whenever a retailer asks.

A calculator that assumed 6% a year

A retailer’s homepage calculator sets power bills to rise 6% a year in a line of code nobody on the sales team has read. The visitor sees a long, rising savings line, and the sales representative never mentions the assumption.

Utah Code 13-52-202 caps an assumed annual electricity rate increase in the disclosure statement at 3%, and requires the retailer’s basis for it. A homeowner who runs the calculator and then reads the paper sees two different pictures inside a week.

• Read the calculator’s code for every default.
• Compare each default to the disclosure statement line by line.
• Change a default in one place so both documents change together.
• Keep a dated record of every assumption and where it came from.

Website design in Utah for residential solar retailers

The Residential Solar Energy Consumer Protection Act is Chapter 52 of Title 13 of the Utah Code. It covers residential solar energy systems installed in Utah that generate electricity primarily for on-site household use, sit on no more than four units of residential real property and have a delivery capacity over one kilowatt.

A solar retailer is a business that sells or proposes to sell such a system, owns a leased one, or sells its electricity under a power purchase agreement. A sales representative is an individual who sells or tries to sell systems through direct contact and is paid in whole or part by commission, or who sets appointments or discusses the benefits of solar energy with a potential customer for a retailer.

Under 13-52-201, the retailer gives the potential customer a separate written disclosure statement at the time of entering a solar agreement. It is in paper form, in at least 12-point font, with the contact details of the customer, the retailer and the expected installer, including the installer’s state contractor license number. The Division of Consumer Protection administers the chapter.

What do the 2026 amendments change for a website?

Chapters 95 and 415 of the 2026 General Session amended sections 102, 202 and 207, and the amended text took effect on May 6, 2026. The sections that matter most for a calculator are 202 and 207.

Does the statute mention websites?

It speaks of any written estimate of projected savings. Whether a web result is a written estimate is a question for counsel or the Division, and a calculator built on the same assumptions keeps the answer from mattering to the customer.

Eight assumptions, eight calculator inputs

Section 13-52-202(2)(b) lists the material assumptions a disclosure statement states whenever the retailer gives a written savings estimate. Web design in Utah for a calculator starts with one input for each, in the statute’s order.

Rate increase, incentives and net metering

These three lines move with the law and the utility, so the calculator carries a date for each and a visible note that they can change.

• Show the assumed rate increase as a figure no higher than the statute’s ceiling.
• Date every incentive input.
• Describe net metering in one reviewed sentence.
• Never import a figure from a utility’s marketing.

Production, degradation and the roof

Production and degradation come from the equipment’s own documents, not from a generic estimate.

• Take the degradation figure from the panel datasheet.
• Show estimated first-year production beside the result.
• Say which roof inputs the design tool used.
• Refresh the numbers when the equipment changes.

Bills, offset, escalator and replacement parts

The last four assumptions are about the customer’s bills and the agreement. The calculator asks for the first two and states the others.

• Ask for the customer’s own bills.
• Show the designed offset in plain words.
• State any payment escalator, with its start.
• State whether equipment replacement costs are assumed.

Pricing a solar retailer’s site and calculator

A site with a custom calculator, a customer portal and a scheduler sits in the ranges below. Pricing depends on scope and is set in the written proposal. Published prices are subject to change.

Progression’s listed prices for a retailer site

These are the fixed-scope prices on our website design and development page, shown as starting prices.

Utah website design for a retailer is usually a custom calculator inside a larger site. A single landing page rarely carries all the assumptions, so the proposal states what the calculator includes and what it leaves out.

Three capital-letter statements beside the result

Section 13-52-202(2)(c) calls for three separate statements in capital letters, in close proximity to any written estimate of projected savings, in substantially this form. The statute reads:

• “THIS IS AN ESTIMATE. UTILITY RATES MAY GO UP OR DOWN AND ACTUAL SAVINGS, IF ANY, MAY VARY. HISTORICAL DATA ARE NOT NECESSARILY REPRESENTATIVE OF FUTURE RESULTS. FOR FURTHER INFORMATION REGARDING RATES, CONTACT YOUR LOCAL UTILITY OR THE STATE PUBLIC SERVICE COMMISSION.”
• “ESTIMATES OF ENERGY PRODUCTION GENERATED BY A RESIDENTIAL SOLAR ENERGY SYSTEM MAY VARY. THE RESIDENTIAL SOLAR ENERGY SYSTEM MAY PRODUCE MORE OR LESS THAN THE ESTIMATED ENERGY PRODUCTION.”
• “TAX AND OTHER FEDERAL, STATE, AND LOCAL INCENTIVES VARY AS TO REFUNDABILITY AND ARE SUBJECT TO CHANGE OR TERMINATION BY LEGISLATIVE OR REGULATORY ACTION, WHICH MAY IMPACT SAVINGS ESTIMATES. CONSULT A TAX PROFESSIONAL FOR MORE INFORMATION.”

The statute places them beside written estimates in the disclosure statement. Whether a web result is a written estimate is a question for counsel or the Division. The plain advice is to place them beside the web result as well, which costs one line of layout and removes a contradiction.

Life of the agreement, or twenty years at most

Section 13-52-202(2)(a) asks for the estimated projected savings over the life of the solar agreement, and, at the retailer’s discretion, over any longer period not exceeding the anticipated 20-year useful life of the system.

The calculator’s horizon selector offers only those two. A longer slider invites a number the paper cannot repeat.

Who signs off on the horizon?

The retailer, with counsel. The web team builds the selector to offer only the two periods the statute names.

• Offer the life of the agreement as the default.
• Offer a longer period only up to 20 years.
• Remove sliders that go past the useful life.
• Print the chosen horizon beside the result.

No promise the paper does not make

The disclosure statement carries a statement in capital letters that no employee or representative of the retailer is authorized to make any promise concerning cost savings, tax benefits, or government or utility incentives that is not contained in the statement, and that the customer should not rely on any promise or estimate that is not included in it.

It also carries a statement that the retailer is not affiliated with any utility company or government agency, and that no employee or representative may claim such affiliation. The homepage, the ads and the landing pages follow the same rule: no utility or government look, and no saving the disclosure statement will not repeat.

Can an ad promise more than the statement?

No. An ad that promises a saving the disclosure statement will not repeat sets up the same contradiction the calculator can.

• Use the retailer’s own colors, not a utility’s.
• Leave out words that imply a government program.
• Repeat no figure that the disclosure statement does not state.
• Review every landing page against the statement before it runs.

Paper at signing, a copy in both forms after

Section 13-52-207 says the retailer gives the customer a copy of the signed agreement with its disclosures in electronic and paper form, unless the customer declines paper in writing, and in the language of the marketing when the retailer marketed in a language other than English. The agreement is not enforceable against the customer without it.

The plain advice: the customer portal stores the signed copy, the cancellation email address and the cancellation mailing address together, in the language the customer was marketed in.

Four business days on the install calendar

Section 13-52-202 requires a statement that the retailer may not begin installation until at least four business days after the day the retailer and customer enter into a contract, and section 13-52-207 sets the same four business day wait from the day the agreement is provided.

The online scheduler never offers an install date inside that window.

What if a customer wants an earlier date?

The scheduler still blocks it. The wait is set by the statute, not by the retailer or the customer.

• Block the first four business days in the scheduler.
• Count business days, not calendar days.
• Show the earliest date as a plain line beside the choices.
• Do not let a sales representative override the block.

Appointment setters on the payroll

Section 13-52-401 says a sales representative shall be an employee of the solar retailer. The definition counts individuals who set appointments or discuss the benefits of solar energy with a potential customer on behalf of a retailer.

The booking and team pages show employees. Any third-party lead form vendor is a question for counsel.

• List only employees on the team page.
• Check any lead form vendor with counsel before launch.
• Keep appointment setting scripts on the same assumptions as the calculator.
• Document who set each appointment.

Custom web design in Utah, not a stock solar widget

Off-the-shelf calculators carry their own default rate increase and incentive logic. A custom build exposes every default to the retailer, who then sets and owns each assumption. Another Utah consumer statute shapes advertising rather than websites; see our page on prize mailers under Utah Code 13-28.

A website builder in Utah or anywhere else can host the page, but the assumptions have to be set by the retailer and checked with counsel. For the marketing side, see our solar marketing agency and solar company SEO pages.

Is a stock widget enough?

Only if the retailer can see and set every default in it. A widget that hides its assumptions cannot be matched to the paper.

• Ask any widget vendor for the default rate increase.
• Reject widgets that hide their assumptions.
• Keep the calculator’s logic in a file the retailer can read.
• Record which version of the calculator ran on which date.

Calculator sign-off sheet

Ten items settle most of the work. The card lists them; the sign-off date is counsel’s, not the web team’s. For a Utah city view, see our web design in Salt Lake City page.
