quiet power house. summer bill tanked. love em
installed 12 of these myself. mounting holes lined up perfect.
The 25-year product warranty gave us confidence in our purchase. The panels have been through a few storms already and have held up perfectly. Great product from Silfab!
The half-cell technology in these panels really makes a difference. Even during partial shading, the energy production remains consistent. Highly recommend for anyone looking to invest in reliable solar panels.
love the warranty time will tell but they’re cranking out power now
Installer said “top tier.” My bill dropped fast.
I really appreciate how you simplified the process of purchasing such advanced equipment. The experience was seamless—thank you!
The service you provided was crucial in helping me confidently choose the Silfab 530W solar panel. The detailed side-by-side comparison of technical specifications and pricing made the decision-making process so much easier. I would definitely recommend your service to anyone looking to make an informed choice about solar products.
They look real nice all black n slick. Had em hooked up in a day.
you do have the prices among the lowest ones around, i'm gonna give it to you. The service is also pretty nice and i'm thankful to melanie for her advice
These panels are built to last. We’ve had them for over a year, and they have endured tornadoes without any issues. Highly recommended.

5 stars for such excellent service and good pickup instructions. I really felt cared for.
so far - working very well. Thanks for the timely delivery and i'll come back for a battery later
Got the package, thanks! The installation started, everything goes as it should so far. My installer (a really nice guy) approved my choice and said that Silfab panels always pay for themselves and not just once here in California, but two or three times.
Five months in, and solar panel is working perfectly. Thank you!

The build quality is really good. really makes you think about how much American-made solar panels are better than Chinese ones. asia panels break all the time but these ones don't. they make them in washington if i'm correct on this.
I've had my panels installed for a few months now, and they're exceeding my expectations. The quality is evident, and the energy production is impressive. Great investment!
Great Warranty. really gives me peace of mind.
I had a few questions about the installation process, and A1Solar's customer support team was incredibly helpful. The panels arrived on time and were easy to install

Choosing the right solar panels was a daunting task for me. i was lost in all the technical details and didn't know where to start. your knowledgeable staff helped me understand the important factors to consider and guided me through the selection process. with their help, I made an informed decision, and the panels are working great. i'm very happy with the support I received.
We bought 100 of those for a project in Texas. Even though it was a big order, A1 team handled the order very professionally. Thanks!
I was impressed by A1's knowledgeable and friendly staff. They helped me choose the perfect solar panel system for my home. Installation was smooth, and the panels have been generating more electricity than expected. Highly recommend!

I ordered from another shop before and it was a complete mess. they didn't handle my order properly and i felt like they didn't care about their customers. luckily, i found your site. your delivery was prompt, the panels were exactly as described, and your team was very supportive. thank you for making this such a wonderful experience. i'll definitely be a repeat customer!

This was a VERY easy purchase! The panels were picked up at the Seattle (Kent) WA location and it literally took less than ten minutes from arrival to departure with panels safely loaded by the staff. They were a rooftop installation on my friend's RV and have worked flawlessly.
hi A1 SolarStore, just wanted to thank you again for fulfilling the order. it was hard for us to find these panels offered by someone who we could trust. You didn't let us down and we're very grateful for that. Burtons
I had no idea which solar panels would be best for my home and felt completely overwhelmed. thankfully, your team stepped in and provided expert recommendations. they helped me weigh the pros and cons of each option and guided me to these in the end.
Great Warranty. really gives me peace of mind.
High price but best suitable for my solar system
We (me and my wife) purchased these panels five months ago for our flower shop in Phoenix. Our electric bills diminished by, i’d say, 80%. Even though I had my doubts in the beginning, now I really know that it was a good decision to go solar. Thank you
grabbed my order at the warehouse. everything is in order. going to store them in the garage until the installation
Chose Silfab for their reliability and efficiency. A1 SolarStore's managers were very professional.

A1Solar team went above and beyond to help me choose the right solar system for my home and they made the entire process stress-free. I'm very satisfied with my purchase
High price but best suitable for my solar system
I purchased these panels mainly because the warranty caught my eye. Never saw a 30 year performance warranty before and decided that these guys probably think highly of their product. Hope to live long enough to see these panels age.

Snap! That was so seamless a process. Normally solar supply stores want to sell pallet loads of panels. Just wanted one over my boat cockpit. Still treated me like it was a big order. Tatiana was awesome. Thanks so much!

Delivery was on time, met expectations.
I looked into it, and Silfab is really one of the best solar panel brands in the world. Excellent for my purposes, competitively priced, and expanding when other businesses are contracting. Btw, all black panels look awesome!

These panels powering my home. Reliable, eco-friendly choice. thanks a1solarstore
The experience of the purchase of the 2 Silfab 490W Solar Panels was a very positive experience. We purchased online of course, then the great communications from A1 Solar started to streamline the product pickup procedure. At the warehouse facility, we were guided to the pickup area and assisted in loaded the panels securely into the back of our truck. We then tested the panels for a week connected to our Bluetti AC200Max with 2 B300 solar backup system. I highly recommend the A1 SolarStore.
One of the reasons I like A1 so much is that they sell so many American-made products. This superb Silfab panel is no exception. I would even go as far as saying that this model is the most technologically advanced of all made on the US territory
Ordered a pallet of 410W Elite panels. Manager, Ivan, deserves applause. Aesthetic and efficient, just wish for clearer installment incstructions
Hi, I'm John, a tech enthusiast and homeowner. We recently bought these Silfab 400W panels, and I have to say I'm pretty impressed. As someone who's into cutting-edge technology, I was drawn to the high efficiency and advanced PERC technology, which I can tell the panels are delivering on the promises even on partly cloudy days. The panel's sleek black design was also a plus, and it blended in nicely with the aesthetics of our home. Highly recommended!
We recently purchased these panels for our home and couldn't be happier with the performance. As someone who cares deeply about the environment, I think going solar was a step long overdue. Installation was a breeze and now the panels are generating even more energy than we expected. Overall, I would highly recommend Silfab to anyone looking for a reliable and efficient solar panel for their home.

A panel like you've never seen before - in a good way. Obsidian-black surface, interesting cell layout, super thin. A piece of art

The panels have performed admirably and effectively. An attractive option for a large system. The cells are not checkerboard blue, but black, it's a pro for me.
My solar panels have been up and running for 8 days as of this review. Someone I trust strongly suggested them, so I went with it. The installation process and obtaining the necessary municipal permissions was the part I was most afraid of. But my installer did all the work and it was a breeze.

The actual power output is comparable to what was stated. There hasn't passed enough time to say much else about the system. As for A1, I can honestly say that I have seldom had such a positive experience dealing with a firm in any industry. Authentic experts!
I support Silfab Solar because it is a local business that produces precisely crafted and highly effective solar panels of the finest quality. And I like A1 store because they treat their customers well and work fast
Because the Silfab panels come with a 25/30 year warranty, we decided to opt for them. The greatest value we found on the market
Outstanding performance across various dimensions. Could not be happier that they are made in North America! I want more Silfab panels in this store
This will be a great choice for anyone who understands the importance of customer support. Silfab has a numerous team in North America and they have helped me a number of times.
good price and looks awesome!
The service and delivery were great, thank you. The panel I found to be quite average, to be honest. The 30-year performance warranty is good though.
grabbed my order at the warehouse. everything is in order. going to store them in the garage until the installation
Silfab is one of the very few brands that designs and manufactures solar panels in North America. That’s what made me consider it in the first place. This 360w model is very light and compact for its power output and I’m glad I made this choice
Panels received and installed! it’s funny, it’s almost like i don’t need commercial electricity at all anymore. Tnx to a1solarstore for the help, their calculation actually helped a lot in sizing the system.

Honestly, i just bought these panels for their warranty. 30 years is no joke. so far they don’t dissapoint, some quality panels right here.

Great solar panels and made in the USA. Very durable and efficient. I highly recommend them.
Very efficient and aesthetically pleasing.
I like that the panels are all black, it was an important consideration for me. They are also American made and come with a great warranty.
These are very light-weight so it was easy to install and they do not add a lot of weight to the roof. They look good too. Come with a fully loaded 25 years warranty. So far, working great!
Very nice fit and finish. They are black with a black frame. They simply disappear into the roof. Also, very efficient.
These panels were very cost-effective compared to other options. They also come with a 25-year warranty that nobody can't beat. I think the quality and performance to date are excellent. We've had our system up and running just under a month and everything is functioning perfectly, as expected.

FAQ
How much is shipping and how long is delivery?
Our standard shipping charge is $250 for up to 11 panels and it is increased by $25 for every 4 additional panels. In the event, the product is only available on East or West coast custom quote will be sent to you before the order is processed. Normally, we are able to deliver solar panels within 7 business days.
What is the difference between low price panels and top price panels?
With top tier solar panels, you pay for the brand name, proprietary new technology, higher energy output, and better warranty support.
What are the dimensions of the panel?
Please refer to the product datasheet on the product page. We have a datasheet for every product we sell.
How long is the warranty on the panel?
In general, manufacturers provide a 25 year-long performance warranty and a 10 year-long equipment guarantee. Some manufacturers offer 12-15 years of warranty. More information is available in our warranty support section.
Which panels do you recommend for RV, marine?
We recommend Panasonic and Mission Solar panels for smaller systems as their high energy output and excellent craftsmanship guarantee years of service.
Can this panel be used with a 12v system?
Any of our panels can be used for a 12v system with a properly selected inverter and charge controller.
Can I pick up this panel from your fulfillment center to save on shipping?
Yes, we can set up a pick up at a local distributor. Please call to discuss options and stock availability.
How do I connect these panels?
To achieve the best system efficiency, panels should be connected in series to create higher voltage.
How many panels do I need?
This number is determined by your average energy needs. Depending on the type of panels and energy consumption, you might need anywhere from 12 to 45 solar panels. Remember, the more panels you install the more energy you will get.Please use our solar calculator to estimate your energy consumption and plan on building a solar system that will exceed your energy needs by 25%.
How do I build a solar system?
Please use our solar calculator to estimate what equipment you need. Choose your panels, microinverters, inverters, and solar batteries if necessary.Please note that we do not offer solar system design or installation.
How do solar panels compare?
Solar panels differ by power output, voltage, connection type, size, efficiency, and weight. Some solar panels might be sold together with microinverters as a set.
Can I build a solar system by myself as a Do It Yourself project?
Yes, it is possible if you understand what solar equipment you need and how to connect it together. However, please be mindful that handling your own electrical work without having proper experience might cause life-threatening injuries. Please contact a certified electrician if you do not possess appropriate electrical skills.
Can I connect and charge my solar panel battery directly with the solar panel?
We do not recommend using the solar panel without the charge controller. Using solar panels without the charge controller might damage the batteries.
Can I drill holes into the aluminum frame for mounting?
We do not recommend drilling any new holes to the aluminum frame of the panel as it could damage the internal circuit and solar cells. (Also, any modification to the panel will void the warranty). We recommend only using the pre-drilled holes for mounting.
Do solar panels require maintenance? Can I wash my solar panel?
Solar panels generally require very little maintenance. We recommend cleaning the solar panel with water, glass cleaner (Windex) and microfiber cloth.
Will my panel produce power in an overcast condition?
While solar panels require sunlight to generate solar energy, they will still work in cloudy weather. Even on a cloudy day, solar panels will produce energy just not as much.
Will my panels produce power if covered with snow?
Solar panels cannot produce electricity if covered with snow.
What is the best direction for a solar panel to face?
The best direction for a solar panel to face is the South
