Five business days, by law
Act 278 requires a seller to provide a prospective customer with a minimum of five business days to evaluate a proposal.
That provision exists because pressure to sign quickly is a recurring feature of residential solar sales, and five days is enough to read the document properly, get a second quote and talk to someone who is not selling you anything.
So if you are being told an offer expires today, or that a price is only available if you sign now, that pressure sits against a statutory minimum you are entitled to.
Use the time for its intended purpose. Read the proposal against the required contents below, and treat anything missing as a question rather than an oversight.
What the proposal must actually contain
A description of the system and its placement, the nameplate generating capacity, and the expected monthly and annual output. That last item is the production estimate this site tells you to ask for everywhere; in Arkansas it is required.
Annual degradation estimates, which is the rate at which output falls over the system life. A projection holding production flat for twenty-five years is inconsistent with a stated degradation figure.
The installation timeline, the total cost, the payment schedule and the payback period, plus forecast monthly and annual bill savings expressed in dollars.
Warranty information and terms, and the results of an energy efficiency audit along with available efficiency measures. That last one is unusual and genuinely useful: efficiency work is often cheaper per dollar saved than generation.
What the seller has to demonstrate
Compliance with all applicable safety requirements and standards, and possession of the permits or certifications required for the work.
A bond or other acceptable financial security to ensure proper maintenance. That is a meaningful protection, because a warranty is only as good as the company standing behind it.
Notice that you may file a complaint with the Attorney General. Ask where that notice appears in your paperwork, since it is required to be given.
Ask to see evidence of the bond or financial security rather than a statement that one exists. That is a reasonable request and a straightforward company will meet it without difficulty.
What the number should be built from
The 30 percent federal Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025, so a cash or loan purchase in Fort Smith receives no federal tax credit, and Arkansas has no state solar tax credit.
Section 48E survives at 30 percent for third-party owners under leases and power purchase agreements, so ask what a provider claims and what reaches you in the rate.
What exists is full retail value for what you consume as it is generated and avoided cost for exports under the non-legacy schedule, since you would be interconnecting after September 30, 2024.
Use the five business days to check the proposal against the statutory list, and treat any missing item as something you are entitled to ask for rather than a favour.
