Want a superior solar company in Southern Nevada?
Did an analysis and comparison of several solar companies in May, 2020, before choosing Sol-up. My choice centered on their data analysis of my needs, the sales staff professionalism, their ability to do what they said when they set out a calendar, and of course, the overall warranty, quality, and cost of the system. Their service staff is top-notch. For example, today(9.10.24), I had a service call from Emmanuel Salcido because of a data communication issue. He analyzed the problem, discovered an unrelated potential issue(fixed it), and updated the system, while providing me with a complete explanation of the "what and why" of his work. Emmanuel was efficient, friendly, on time, and professional. One could not ask for a better technician who takes extreme pride in his work and his company. One can learn so much about a company by looking closely at those they train to service their product and interact with the public. Sol-up is to be congratulated for employing professionals like Emmanuel.

Good and Bad
The good is that the solar panels were installed and now I have my electricty is $19/month. Another good and bad is that the system was late to be installed by a couple months but I was credited a month's worth of utility expense by Sol-Up and my sales rep. The bad is Sol-Up recommended and does business with a local family owned company called Ariat Roofing. Ariat was very misleading in their bidding process and what they said in person didn't match the fine print. Even worse is they labled the attachments in a way that was further misleading to hide what you think you are paying for. Basically in person they said they would give me two bids one for entire roof and another for just the areas where the solar panels would be. They gave me two prices via email one to redo the entire roof and another to just do the areas where the solar panels would be. On their bids attached it also said entire roof and solar areas also. When you open up the fine print and read it, it's different than what they said in person. It turns out the fine print said they would replace the "entire upper roof" not the "entire roof" which makes no sense considering they advised me that the underlayment has expired and I needed to replace the entire roof not just the entire upper roof. Why would they not provide me a bid for the "entire" roof after telling me it all needed to be replaced? After calling them out on it they agreed that it was misleading and apologized and said they would replace the lower roof as well at their material cost only and would cover all the labor costs. That cost would have been around $500 as underlayment and some battons just don't cost that much for such a small section of roof. They came out and said another $3000 is what I have to pay. It's a joke. I paid for an entire roof and they didn't finish the job. Thankfully my father in law noticed they didn't do the lower section so when I called to confirm they in fact said they only did the upper section. After reaching out to my rep Brian Grinn at Sol-Up he kept saying hes going to ask a Mr. Sweet and make it right, but that never happened and now it's been 4 months and now my communications are being ignored. My experience with Sol-Up was ok but I would not do business with people they recommend especially Ariat Roofing as they are very deceiving. Now I have have warranties with these companies and very nervous about their practices.

A fine new roof
Max Sigua has been my very capable and attentive project lead. The price for the project is fair. The end results are a professionally done roof. Max chose capable roofers and a capable solar panel installer to complete my project. I already have solar. So in this project it was remove the panels then replace the roof and the. Reinstall the solar. It’s a beautiful roof now! It’s also a very cool (temp) roof. I expect big things of this energy saving roof! Attached are pics of the roof. I highly recommend AMECO. Max Sigua communicates with me all the way through the project.

Incompetent
Incompetent is too nice a word to describe Ameco. They delayed my project by weeks because their surveyor could not get the correct measurements the TWO times he came. I had to finish the measurements my self to not delay the project further. They then decided not to follow their own plan when installing the panels which caused inspection to fail and having to resubmit plans again causing another delay.

Sunriver Did a Great Job
Six months ago, in the fall of 2023 I had a solar energy system installed on my home. The installation company was Sunriver Solar, out of Auburn, CA. From all aspects of design, consultation, estimation, to installation, Sunriver did an excellent job.

Not a good experience
Long story short, this company messed up our contract by moving the project up by 3 months, then telling us we couldn't add a battery because it was too 'last minute" even though we told them multiple times through the whole process that's what we wanted. Overall, we ended up having to pay over $800 to not be sued in court??? Because we wanted out of a $70k contract that THEY messed up.

Best solar companies for home battery installations in California
Batteries have become increasingly popular because they take an intermittent energy source like solar and turn it into a reliable and consistent supply of electricity. We recommend getting a solar battery quote if you want a backup power source or if your utility company doesn’t have a net metering program that buys excess solar energy at the full price of power, as you could save a little extra on your electric bill.
California is one of the best places in the country for installing a solar battery. First, the state’s Self Generation Incentive Program (SGIP) provides rebates to homeowners that directly reduce the cost of energy storage installation. California also enacted NEM 3.0 in April 2023, which changed how major utilities bill solar customers and has made installing a battery an excellent financial investment. Plus, power blackouts have become more common across California, making the backup power home batteries can provide is valuable.
Here are some California companies that install panels and solar battery storage systems:

How to find the best solar panel company near you
Picking a solar company is the most important decision you make when going solar. You need to trust them to drill holes in your roof, help you navigate financing and incentives and provide you with 25+ years of customer service.
Check out this video where our founder, who also founded a successful solar installation company, explains what to look for when choosing the best solar company near you.
Top things to consider when choosing a solar company in California:
Years in business
One of the first things to look at when finding a company is how long they have been in business. We suggest looking for companies that have been around for at least five years, as the longer it has been in business, the more likely it is you’ll have a positive installation experience.
Companies with five or more years of experience will probably have established after-sales service and warranty support. It signals that they aren’t a company in it to make a quick buck; they’re in it for the long haul.
Of course, there are exceptions to this rule, which is why you should also keep a few other factors in mind.
Licenses, insurance and certifications
Solar companies that are licensed, insured and hold certifications take their business seriously. Look for companies that have NABCEP Certified professionals or certified electricians on staff and are properly insured, so their workers, and you, are protected.
In California, installers are required to have either a general contractors license or a C-46 Solar Contractors License. This license covers installations for photovoltaic systems, solar water and space heating, and solar pool heating. Additional requirements include written examinations and four years of experience in the form of technical training, apprenticeship, or practical experience.
Financing options
Not everyone has thousands of dollars to spend on a solar panel installation. So, you’ll want to find a company with solar financing options that work for you. Ask for quotes for various types of financing plans to see which one will work best for your budget. Solar loans are often your next best choice if you can’t pay in cash. But, if you don’t pay federal income taxes or can’t qualify for a loan, finding a company that offers solar leases or power purchase agreements might be the right move.
Services and products offered
Don’t choose a company that can’t complete the job that you want to be done. If you need an energy storage system, get quotes from companies that install batteries! Maybe you want a particular brand of panels or an electric vehicle charger installation. Ask the company if they provide those services or carry those brands so you don’t have to settle for less.
Customer review scores
Customer ratings give valuable insight into how a solar company actually operates and treats its customers. Read SolarReviews, Google and Yelp reviews to understand the company’s installation process, sales practices and overall customer service. But remember that some companies incentivize customers to leave positive reviews, so make sure you read reviews with some scrutiny.
Warranty
Any reputable solar installation company will offer a workmanship or labor warranty that covers any damages that may occur during the installation process. We recommend using an installer with at least a ten-year labor warranty.
Some installation companies, like SunPower, include a system performance guarantee. This promises you’ll get a certain amount of electricity from your solar panels and is an excellent added protection.
California incentives and rebates
Solar incentives and rebates can cut the cost of installing solar in California by thousands of dollars. The most significant incentive is the 30% federal solar tax credit, available to any taxpayer in the country when they purchase solar panels or battery storage.
Some states and utility companies offer additional solar incentives, saving homeowners even more money. Here are the solar incentives available in California:
Incentive | Eligibility | Type |
---|---|---|
Residential Clean Energy Tax Credit | Federal | Personal Tax Credit |
Self-Generation Incentive Program | State | Battery Rebate |
Property Tax Exclusion for Solar Energy Systems | State | Property Tax Incentive |
Net Billing (NEM 3.0) | State | Net Metering |
How much can you save with solar incentives?
What to look for in solar quotes in California
Once you’ve found a few companies you like, you can start getting solar quotes. You can get a better deal when you get quotes from multiple solar installers; we suggest getting at least three quotes. Here are a few of my favorite tips and tricks for comparing quotes and what questions you should ask installers.
System size and energy production
All solar quotes should include the size of the system and how much energy it is projected to produce. Most of the quotes you get will probably be in the same ballpark. But, if one is drastically larger or smaller than the others — ask about it! Maybe one installer included shading from a tree, while another based its estimates on having that tree removed.
California is one of the sunniest states in the country, with an average of 284 sunny days each year and between 5 and 7.5 peak sun hours each day. The more sunlight available to the panels, the more electricity the system can produce. But, all this sun also leads to hotter temperatures. This may lead to increased energy usage to keep homes cool, meaning you might need some extra solar panels to support all that electricity consumption.
If you choose reliable installers, you can trust that these estimates will be as accurate as possible. But you can always double-check using the SolarReviews solar calculator and enter the information received in your quotes.
Pricing
You should know as much as possible about how much the solar panels cost. Make sure you know both the total cost of the system and the price per watt of solar installed. The cost per watt makes it easier to compare prices between quotes and gives you a better idea of how fairly the system is priced. The average price of solar is about $2.14 to $3.22 per watt in California, so anything in that range is a fair price.
Financing
Financing is one of the most important things to look for in your solar quote. There are a few different things to keep an eye out for, depending on what type of solar financing you’re using.
If you’re looking to use a solar loan, you should ask the company for both a cash quote and the financed quote. Solar loans include something called dealer fees, which can sometimes add 20% or more to the total cost of your system in exchange for a lower interest rate. It’s worth comparing what dealer fees and interest rates you’re quoted from different companies to get the best deal possible.
If you want a solar lease or power purchase agreement (PPA), you’ll want to look for an escalator clause in the contract. The escalator clause outlines how much your payments will go up every year. Ideally, this should be lower than the rate at which electric prices increase in your area, typically about 3% annually. If the escalator rate is higher than this, you could end up paying more than if you hadn’t gone solar at all!
Payback period
Some quotes may include when you’ll break even, meaning when your panels have saved as much as you spent on them. If it’s not explicitly listed on the quote, you can compare any savings estimates they provide to the system’s total price and get a rough estimate of when your panels will pay themselves off. The shorter the payback period, the better.
Equipment
Good quality solar installers will carry good quality equipment. So if you pick an installer you trust, you can expect reliable products. But, it can’t hurt to research and ask the installer questions about what would be going on your roof.
Most solar panels installed today are about 400 watts in size and have efficiency ratings above 19%. Higher wattage and efficiency panels can produce slightly more electricity but may add a price premium. You’ll want to make sure the solar panels have the industry standard 25-year product and performance warranties.
