Features
- Bifacial Tech, Up to 15% Extra PowerDesigned with advanced bifacial technology, HQST 100W Solar Panels capture direct sunlight on the front and reflected sunlight (albedo) on the rear. The result? Up to 15% more energy output than traditional panels, delivering up to 115W of power from a 100W panel. Maximize your solar potential with HQST!
- Installation Tips for Maximum Power OutputMaximize energy output by installing bifacial solar panels on reflective surfaces or mounting them above the ground to capture more rear-side sunlight. For optimal results, set the solar panels at an angle between 20 and 45 in highly reflective areas like snow, cement, sand, grass, or white surfaces.
- Grade A+ Cells, Up to 25% EfficiencyHQST 100W 12V solar panels feature advanced Grade A+ 9-busbar solar cells, rigorously tested with EL technology to ensure zero cracks. With an outstanding conversion rate of up to 25%, they outperform traditional panels and deliver better performance.
- Enhanced Low-Light PerformanceHQST solar panels utilize advanced PERC solar cell technology to maximize energy conversion. By reflecting unused sunlight back into the cell, PERC cells capture more light, including low-energy infrared, making them highly efficient in cloudy or low-light conditions. Built-in bypass diodes prevent overheating and ensure the panels continue performing even when partially shaded.
- Built to Last, A Smart InvestmentRated IP68 for dust and water resistance, this 100W solar panel is built to withstand dirt, splashes, and rain with ease. Its anti-corrosion aluminum alloy frame ensures decades of outdoor reliability. Engineered to handle extreme conditions, it boasts 2400 Pa wind resistance and 5400 Pa snow load capacity. Delivering powerful energy output for up to 30 years, its a smart, long-lasting investment for sustainable power.

I bought these panels for two reasons: The price and the size. I have actually bought 16 of these panels - 4 different times I've purchased the 4-pack of 100 watt panels. They are nearly $100 cheaper for the 4-pack today than they were when I bought the first 4-pack. As of March 18, 2023 they are $274.99 for the 4-pack of 100 watt panels and there simply isn't a better deal for new panels than that anywhere. The other thing that steered me towards these was the size. I wanted to be able to take these with me - at least a few of them - on the road if I needed to and as someone who doesn't own a truck or a van, these panels were the perfect size for being able to toss them in my car. And they are rather light weight, too, on a single panel basis at just over 13 pounds. As for the panels themselves and how they work - they work great. During a clear day, at peak sun, I will get anywhere from 97% to 102% of the rated output of the panels. In order to get that kind of output you are going to need to dial in the angle of the panels, but if you do get it right you can get the full output with these. The only "con" to these panels is that the MC4 cables are a little bit short. You have plenty of room to connect one panel to the other when they are next to each other, but compared to some other brands they are a bit shorter cables with less wiggle room for your potential set up. As noted though - you shouldn't have any issues connecting one to the other if they are next to each other. This "con" is very nitpicky, but it felt worth mentioning as not every person purchasing them will be mounting multiple panels that are touching each other. If you are in the market for 100 watt panels then I would very highly recommend these.

Good value and quality. With the right Grid tie inverter or battery charger these panels will easily exceed their rated output

I was apprehensive to order these at first, but I'm glad I did. These are an amazing deal for the quality they are! The listing is accurate! My application was to mount 3 of them on my 36v golf cart and never have to plug it in to charge again. And I haven't had to plug it in for MONTHS! I used 3 on my golf cart roof and in full sun they are producing 45volts. On cloudy days it's 43volts. I often have to drape a towel over them because my golf cart won't let me drive it when it's recieving that high of a charge. My husband used the remaining one in his workshop to run some lights and keep batteries charged. Overall, amazing deal and quality product! Will definitely be converting more things to solar soon and will order these to do the job!

Received my panels and they were shipped with good packaging and it was secure, even for being 4 panels to one box and no outer shipping box. I didn’t unpack them for about a week as my project ran into things that prevented me from immediately examining the panels. I did an brief check and none were damaged. I did run into a problem where the junction box cover was missing on one. I contacted customer support, and though they are on a different time zone, their response was within about 12-14 hrs. They were very helpful in getting me a replacement cover so I could use the final panel. All panels tested between 19-21 volts in clear sky and noon time sun. For the price and quality, these panels look too be good choices. If anything goes on while I begin using them in my off-grid situation I will update. Otherwise, happy with the panels.
