Buying solar
Is solar worth it in Las Vegas?
The honest case and the honest case against, using the market payback figure, what the export credit pays, and the four things that decide it for your roof.
The sunshine is not the question. Las Vegas has plenty and everybody selling solar here says so. The question is whether the money works on your roof, and the answer moves a long way from house to house.
Start with the market number. EnergySage puts Las Vegas payback at 18.29 years as of September 2026, against $2.42 per watt installed. That is an average across many roofs and many sizes, and it is longer than most advertising implies. It is also not your number.
Four things move it, and one of them matters more than the rest.
1. What share you use rather than export
This is the big one, and most people have never heard of it.
Under NMR-405 Tier 4, the power you send back is credited at $0.08717 per kilowatt hour on the schedule effective July 1 2026. The power you buy costs $0.11935 all in on Schedule RS. So a kilowatt hour used inside your own house is worth about 37 percent more than the same kilowatt hour exported.
That turns a question about panels into a question about your day.
| Household | What it does with midday generation | Effect on payback |
|---|---|---|
| Someone home, cooling running, pool pump, EV charging in daylight | Uses most of it | Better than the average |
| Empty house 8 to 6, everything runs in the evening | Exports most of it | Worse than the average |
What "75% of retail" actually costs you works the difference through, and net metering in Nevada explains the monthly netting that decides which bucket a kilowatt hour lands in.
2. How big your bill is now
Solar replaces energy charges. It cannot touch the rest.
Credits cannot be applied to the basic service charge, which is $18.00 a month on Schedule RS, nor to additional meter charges or local government fees. So there is a floor under every bill, and the smaller your energy charge is to begin with, the smaller the thing solar is working on.
A household paying a large summer bill has more to displace and does better. A household with a genuinely small bill may find the arithmetic never gets there, and that is a legitimate answer.
What a Las Vegas home actually pays per kilowatt hour has the full rate picture, including the October 1 2026 reset.
3. What you pay for the system
Obvious, but it is the part people compare worst. Two quotes for the same house differ mostly by system size, and totals hide that. Price per watt is the only figure that compares. What solar costs in Las Vegas in 2026 covers what moves a quote and what to ask for in writing.
4. How the federal credit reaches you now
This changed under everyone's feet and a lot of published advice has not caught up.
The credit a household claimed on its own purchase is finished for property placed in service after December 31 2025. A credit still exists, but it belongs to the owner of the system, which means it now reaches a homeowner only through a structure where somebody else owns the array, and it arrives as price rather than as money back.
Any payback calculation that still assumes a household credit on a cash purchase is wrong by a large margin. What the federal solar tax credit is worth to you in 2026 sets out both sections and the dates.
The thing most calculations leave out
From January 1 2027, southern Nevada bills gain a daily demand charge priced on the highest 15 minutes of use in a day. It is scheduled for January 1 2027, under appeal, and net metering credits will not offset it.
It does not make solar not worth it. It does mean a calculation built only on today's bill structure is incomplete, and it is a fair question to put to anyone quoting you: how have you accounted for it? The daily demand charge tracks where it stands.
If you might move
Nevada requires the utility to let you continue net metering at the original location for 20 years, and the arrangement is attached to the address rather than to you. An owned system conveys with the house.
So a shorter stay does not automatically make it a bad idea, but it changes what you are buying: a lower bill while you are there, plus whatever the arrangement is worth to a buyer, rather than a full payback you personally see through. If the system is leased or on a power purchase agreement instead, the transfer clause becomes the thing that matters most.
Who it is probably not worth it for
We would rather say this than not.
- A genuinely small bill, where there is not enough energy charge to displace.
- A roof within a few years of replacement. Take the array off and put it back and you have paid twice.
- Heavy shading that no layout solves.
- A short expected stay combined with a lease or a power purchase agreement rather than ownership.
If any of those is your situation, the honest answer is probably not, or not yet.
How to get your own number rather than an average
- Pull twelve months of your own usage from NV Energy, including the interval data.
- Work out roughly what share of it happens in daylight. That is the self consumption question.
- Get quotes with the price per watt and the first year production estimate on the same page.
- Ask each company what happens to the arithmetic when the daily demand charge starts.
We will do that with your own bills and tell you what we find. If your roof is not a good candidate we will say so, which is a faster answer for both of us.
Questions people ask us
Is solar actually worth it in Las Vegas?
It depends on your bill and how you use power, not on the sunshine. EnergySage puts Las Vegas payback at 18.29 years as of September 2026. A household with a large summer bill that uses most of its own generation does considerably better than that average. A household with a small bill that exports most of it does worse.
What is the single biggest factor?
How much of what you generate you use inside the house. Under NMR-405 Tier 4 an exported kilowatt hour is credited at $0.08717 while a kilowatt hour you buy costs $0.11935 all in on Schedule RS. Self consumption is worth about 37 percent more than export, so a daytime household does better than an empty house.
Did the tax credit change make solar not worth it?
It changed the arithmetic, it did not end it. The credit a household claimed on its own purchase ended for property placed in service after December 31 2025. A credit still exists for the owner of a system, so it now reaches a homeowner through a structure where somebody else owns the array, and it arrives as price rather than money back.
Is it worth it if I might move in five years?
Possibly, but the question changes. Nevada locks the net metering arrangement to the address for 20 years, and an owned system conveys with the house. What you are buying then is a lower bill for five years plus whatever the arrangement is worth to a buyer, not a 20 year payback you will personally see through.
Does the new demand charge change the answer?
It is a new bill component scheduled for January 1 2027 and under appeal, and net metering credits will not offset it. It does not make solar not worth it, but it does mean any calculation built only on today's bill structure is incomplete. Ask any company quoting you how they have accounted for it.
Who should probably not buy solar?
A household with a genuinely small bill, a roof that needs replacing soon, a short expected stay combined with a lease or a power purchase agreement, or heavy shading. A good company will tell you that. If your roof is not a good candidate, hearing so is the faster answer for both of us.
