This is Very good product. It generates enough solar electricity I want。
Great product. Also easy and systematic pickup. Very very pleased. Bought 9 panels and saving to buy another 10.
Works perfectly and generates more power than I expected. Fast shipping too. Very happy with my purchase!
Installed these on our roof and they’re doing great. No issues so far, good quality for the price.

The panels represent a great $/watt price point. Ordering and pickup from A1 SolarStore was quick and painless
As a business owner, switching to solar reduced my operating costs significantly. Highly recommended
We installed solar panels on our warehouse, and the tax credits alone made it worth it
some were broken but a1 replaced them quite fast

Hi Melanie,
thanks a lot for your help. our order arrived safely and I'm currently looking for an installer. I had a lot of pleasure dealing with A1 and I might come back if I decide to add something
Fantastic solar panels! I’ve seen a huge drop in my electricity bill, and they work great even on partially cloudy days.
Very efficient and durable. We had a hailstorm recently, and they weren’t damaged at all. Highly recommend!
Bought a full pallet for my solar project. Easy to install and working well. Would buy again!

Panels are good, but a few were broken during delivery, the company replaced them quickly
The solar panels are working well for us. They provide a steady amount of energy but not as much as the datasheet says. i'm told it's normal. Overall, I’m happy with the purchase and would recommend these panels to others.

The moment I contacted the firm, everyone I spoke with went above and beyond to assist me. They did excellent job, were courteous and helpful even when I asked dumb questions. It took less than five days to deliver everything. This is a customer-centric business that values its customers and strives to provide them with the highest quality service.
These panels are of excellent quality and look identical to expensive ones made in the USA. They have a 25-year performance guarantee in addition to the 20-year manufacturer's warranty. It was a great decision to go with JA solar panels.
Picked up my order from their warehouse, super convenient. Highly recommend!

Chose these panels at last. The guys at A1 made the process of going solar stress-free - friendly and always available to answer all my questions. Would definitely recommend them
Panels are good, but a few were broken during delivery, the company replaced them quickly
Nice-looking panels. It's still early on, but so far everything appears to function as expected. A1 did a great job delivering them on time and uncracked
The panels seem to be doing their job effectively. Installation was pretty simple, and since we’ve had them, they’ve been helping to cut down our electricity costs. The performance has been consistent, and we have no complaints so far.
Deciding which solar panels to buy was quite challenging for me. there were too many choices, and I didn't understand the technical details. your team was amazing – they guided me through the selection process and made sure I understood the benefits of each option. with their help, I chose the perfect panels for my home. they are working great, and I couldn't be more satisfied.
Decents panels. feel a bit thin and flimsy. the service was very good though. they really care for you

Nice-looking panels. It's still early on, but so far everything appears to function as expected. A1 did a great job delivering them on time and uncracked
The installer suggested these panels due to their reasonable price, long warranty period, and high reliability. So far we can say that the installer was right
I was a little confused by QC4 connectors but called the store and got a great explanation. Everyone was so nice, I really liked the service. The equipment arrived on time and in one piece too

Great for my farm! Using solar panels to power irrigation has saved me a fortune
Wow, 410w at a little over 45 lbs! Even more surprising if you take the price into account. Definitely recommend!
Unbeatable price per watt, good warranty. The store allows you to pick up the panels at one of their fulfillment centers, very convenient. You’re the best, guys

Unfortunately, Jinko is no longer an option, so we had to settle for JA Solar. What we are after is the highest quality at the lowest price. Our clients are happy.

I recently purchased this JA Solar 385 W model for my home, and I am extremely pleased with the results. As an environmental consultant, I prioritize using sustainable energy sources, and this panel provides an excellent option for anyone looking to reduce their carbon footprint. The panel is efficient and reliable, producing a high output of electricity with minimal maintenance required. I only wish there were more pickup centers nearby, I hope you work on that in the future

I'm a construction worker and we've been using these panels for a few weeks now. These are solid panels that get the job done. They're durable and can withstand the weather conditions at my worksite. It's not the cheapest option out there, but you get what you pay for. I've noticed a significant decrease in our electricity bills since installing these panels.

The service is very good. The calculator I found to be very helpful. plus the map with fullment centers. I feel like everything just flows right here.
Well, everybody knows JA Solar, they’ve been around forever. a good brand imo. Panels are cheap, but they are quality enough. The production is fine. The service here impressed me and for that i give 5 stars.
cheap and powerful — all i was looking for.

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.
