I was worried about how these panels would perform in Texas heat, but they handle high temperatures well. No drop in efficiency, even when it’s scorching outside.
I run a small farm, and these solar panels help power my irrigation system. They handle the workload well, even during peak summer months.
I've been using for over a year already. no issues so far. In fact, I came back for another pallet for my vacation home and decided to drop a review
Choosing the right solar panels was challenging, but the staff made it much easier. Their expertise was invaluable, and I ended up making an informed decision that I'm very satisfied with. The panels are working great, and I couldn't be happier.

I've been using these panels for a year now in the Nevada desert and they've been working fantastic. I'm pulling power out of 27 of them (3 arrays of 9 panels) with two EG4 6000XP and getting better than expected efficiency.
Good customer service, but one of the solar panels arrived damaged. It was replaced without any issues

The panels are working fine so far , I run an 8 KW system
Very good service and panels
Everything LOOKS good, but while the spec sheet and web site list the load ratings at 5400 / 2400 pa, the actual sticker on the module says 3600 / 1600 pa. Be careful if you live in a high snow/wind load area!
These panels deliver outstanding performance. We used them for a commercial project, and the results have been fantastic. Highly recommend for anyone looking for a reliable solar solution!
The panels work well, but if they’re not installed over a reflective surface, the bifacial effect is minimal. Other than that, they are high-quality and efficient!
I appreciate your service. Your engineer was very skillful and Melanie on the phone is a sweetheart
These are great reliable panels, and 4 of them a a great match for EcoFlow Delta Pro power stations.
appears to be working to specifications. thanks A1 Solar!
The panels are great, but proper installation is key to maximizing the bifacial effect. Be sure to place them over a reflective surface to get the best results.

Instead of spending a fortune on LG NeON panels, you can get comparable performance from these Phono solar panels... Perform as intended...
Installed 10 of these panels on my roof, and they generate plenty of power even during winter. The bifacial technology really works – the backside also contributes to energy production. Highly recommend!

Lovely, modern-looking panels. A very good impression from the panels thus far. The panels themselves show about 5% production-related variation, but I guess this is normal

Hey guys, just wanted to leave a quick review for the Phono 400W solar panels I recently purchased from A1. I gotta say, I'm pretty impressed. The installation process was a bit of a pain, but that's just because I'm not really a DIY guy. Once the system was up and running though, it's been smooth sailing. I've noticed a significant decrease in my energy bills, and it feels great knowing that I'm doing my part for the environment.
A1Solar was recommended by a family member. Always great prices, fast deliveries, knowledgeable staff
The panels have been up and running for me for a little over a month without a hitch. They're the perfect color match for my roof's dark gray shingles, and they look great there.
To be honest, we did not choose these panels, just took the advice of our installer. So far Phono seems a very solid brand
Phono Solar is a huge, highly diversified company with solid financials. I opted for the all-black variety of solar panels, so they stand out visually. The energy output is in line with expectations. The item has exceeded my expectations.
They deliver exactly what was advertised in the datasheet. The contrast between the silver and the black looks very impressive.

A reliable workhorse. But what it has in reliability and affordability it lacks in aesthetics
Cheap and reliable
Hi, I'm Kim and I recently had the Phono 545 TwinPlus panels installed on our roof. I was looking for a solar panel that could produce enough energy for my small business, and this one exceeded my expectations. The 144 cells generate a lot of power even on cloudy days, and the panels blend in well with my roof. The installation and interconnection were quick and easy, and the panels seem durable and well-built.
I installed the Phono 400 W solar panels on my roof and I'm happy with how they're performing. The installation was straightforward and the modules look well-made. I like that it packs a lot of power in a compact size. I haven't had any issues with so far, and I get quite a bit of energy even on cloudy days. Overall, I would recommend this panel to anyone looking for a reliable, cheap and high-performing panels.
In reality, the panels are producing just a little bit more than their rating. A1 solar has the best service and fastest deliveries

Pickup is one thing that most of the other solar stores don't have and A1 does. No more worrying about getting broken panels or waiting for days, just make an order and pick it up the next day after work. But it is very disappointing to discover that a panel you need is not available at a nearby fulfillment center. I hope you fix this in the future

So far, everything appears okay. I believe we generate around 40 each day, but I'm not sure. The most generation happens from 10 am to 4 pm.
Need a few more months and bills before I can comment on our new system. But the store did a great job, we enjoyed working with you guys
Due to the configuration of our roof, the system had to be divided into three arrays, each having 16 panels facing west and 8 panels facing north. We generate 40 kWh on average daily and nearly 60 kWh on clear days. For our purposes, the micro inverters are wonderful. We couldn't produce anything close to these numbers using a string system.
