Short answer: Put every quote on one written scope, then compare the same seven things: system size in DC kW, annual kWh, equipment models, total cost on one page, price per watt, warranties, and payment terms. If a quote cannot answer one of those in writing, mark it "unknown," not zero, and do not choose it on price alone.
Below is the exact process, in plain language, with Las Vegas specifics.
Why are Las Vegas solar quotes so hard to compare?
Because every company bundles different things. One quote includes a battery and a roof repair. Another leaves out electrical panel work. A third quotes a bigger system with a smaller production number. The totals look comparable and are not.
On top of that, NV Energy starts Daily Demand billing on January 1, 2027, so a savings number built on the old rate structure may not hold. Ask every company which rate structure its estimate uses. You can read the details in our guide: NV Energy 2027 Billing Change: What It Means for Solar.
Step 1: Write one scope and give it to every company
One scope, in writing, sent to all of them. List what you want: roof type and condition, system size range, battery yes or no (and its purpose), EV charger plans, and panel upgrade if needed. When every company prices the same job, the numbers become comparable.
Step 2: Check the license before you check the price
Verify each contractor with the Nevada State Contractors Board. An unlicensed or problem contractor makes a low price meaningless. Use the Board's contractor license search. You can search by license number, company name, or the name of a principal or qualified individual. Do this before you read the quote.
The Board notes that its search results are provided as a courtesy and may not reflect recent changes, so treat the lookup as a first check, not a guarantee.
Step 3: Put size and production on separate lines
Ask for three numbers, each on its own line:
- DC array size in kW (the panels)
- AC inverter size in kW
- Estimated annual production in kWh
Do not accept a quote that mixes DC and AC, or annual and monthly, without conversion. Mixed units are how a smaller system gets dressed up as a bigger one.
Step 4: Calculate price per watt
Divide the total system price by DC watts. Example: a 7,000 watt (7 kW) DC system priced at $21,000 is $3.00 per watt. That example is only to show the math, not a price you should expect.
Price per watt is a comparison tool between your own quotes. It only works if the scope is the same. A quote with a battery will look expensive per watt, so strip the battery out or compare it separately.
Step 5: Put every cost on one page
Add everything on a single sheet: equipment, labor, permits, electrical upgrades, roof work, battery, financing fees, and any dealer fee built into a loan. If the net price depends on a tax benefit, write down the benefit's name, the legal basis, who is eligible, and when it applies, then verify it yourself against official sources. If you cannot verify it, mark it "unknown."
Step 6: Compare cash price to financed price
Financing can hide a lot. Compare the total you will pay over the loan or lease, including fees, against the cash price. If a payment has an escalator, calculate what year ten and year twenty look like. Then stress-test it: what happens if you sell the house in five years, or production comes in lower than promised?
Step 7: Read the signed documents, not the sales illustration
The installation agreement and finance agreement control, not the slideshow. Check them against the proposal for system size, equipment, warranties, and payment schedule. Pause or walk away if you see blank spaces, inconsistent schedules, unsigned copies, or numbers that disagree between the proposal and the contract. Keep digital copies of everything.
What do the red flags look like?
| Red flag | Why it matters |
|---|---|
| Price good only if you sign today | Real deals survive a night of sleep |
| Savings number with no source or assumptions | You cannot test what you cannot see |
| Proposal and contract disagree | The contract is what binds you |
| Blank fields in the agreement | Someone can fill them in later |
| Missing equipment model numbers | You cannot check warranty or specs |
| Net cost depends on a benefit nobody can name | Eligibility is your risk, not theirs |
| Battery included with no stated purpose | One battery cannot do every job |
FAQ
How many solar quotes should I get in Las Vegas?
Three is a practical number. Fewer gives you little to compare, and many more gets hard to normalize. Give every company the same written scope so the quotes line up, and verify each contractor's license before you compare price.
What is a fair price per watt for solar in Las Vegas?
There is no single right number, and prices change over time. Calculate price per watt for each of your own quotes, using the same scope, and see which ones stand out. Batteries, roof work, and electrical upgrades all change the result, so strip them out or compare them separately.
Is the lowest solar quote the best one?
Not automatically. A low quote can leave out equipment, roof work, electrical upgrades, or warranty coverage. Explain every missing item before choosing the lowest price. The best quote is the one whose written scope, production, and terms hold up line by line.
How do I check a solar contractor's license in Nevada?
Use the Nevada State Contractors Board's online license search. Enter the license number from the proposal, or search by company name, and confirm the license is active and covers the work being done. Do this before reviewing price.
Does the new NV Energy billing change affect solar quotes?
Yes, it can. NV Energy's Daily Demand billing starts January 1, 2027 for residential and small commercial customers in Southern Nevada. Estimates built only on annual kWh offset may not reflect it. Ask each company to show your estimated bill under the current rate structure, line by line, and to state its assumptions in writing.
