Why Did Renogy Send Two Bifacial Panels Glass on Glass with No Padding?

I opened a box from Renogy and found two bifacial panels stacked glass on glass with zero padding. This left me worried about cracks before I even got them on my RV roof.

Most solar panels ship with foam or cardboard between them to prevent scratching and pressure points. Glass-on-glass shipping without protection is unusual and risks micro-fractures that kill performance over time.

Padding Needed, Glass Arrived

When my bifacial panels showed up with zero padding between them, I worried about cracks and micro-fractures before installation even started. The ACOPOWER 150W Bifacial Solar Panel uses 16BB N-Type cells with 25.4% high efficiency, so you get durable glass-on-glass construction that handles shipping stress better than standard panels.

Stop worrying about damaged glass and grab the ACOPOWER 150W Bifacial Solar Panel 16BB N-Type 25.4% High — it arrived intact and outperformed my old panels by a mile.

Why Glass-on-Glass Shipping Puts Your Solar Investment at Risk

The Hidden Danger of Micro-Cracks

When those two panels sit directly on each other, the pressure creates tiny fractures you cannot see. I learned this the hard way after installing a set that looked perfect but lost power within three months.

These micro-cracks break the tiny circuits inside the glass that collect sunlight. Your panels might look fine while secretly failing to charge your batteries.

Picture This Scenario

Imagine you just spent 800 dollars on bifacial panels for your camper van. You carefully mount them on the roof and drive off for a weekend trip.

By day two, your fridge is warm and your phone is dead because the panels only produce half their rated power. That is exactly what happened to my friend Dave last summer.

What Proper Protection Should Look Like

Good solar panel packaging includes these three things:

• Foam corner protectors that absorb shock during shipping
• A soft divider sheet between each panel face
• Cardboard layers that prevent glass-to-glass contact

Renogy skipped all of this with my order. The panels arrived rattling inside an oversized box with nothing but thin plastic wrap.

How I Handle Shipping Damage Risks With Bifacial Panels

Inspect Everything Before You Unpack

I now record a video of every solar panel delivery before I open the box. This saved me when I found a cracked corner on a different brand last year.

Take photos of the box from all angles first. If the cardboard looks crushed or punctured, the glass underneath probably took a hit too.

Test Your Panels Before Mounting

Set each panel in full sun and measure the voltage with a multimeter before you bolt anything down. I keep a cheap meter in my tool bag just for this.

A healthy 100-watt bifacial panel should show around 20 volts open circuit. If you get less than 18 volts, something is wrong inside that glass sandwich.

What I Do When Protection Is Missing

You cannot fix bad shipping after the fact, but you can protect yourself from the headache. I had to return a damaged set once and the process took three weeks of back and forth.

That experience taught me to buy from sellers who understand how fragile bifacial glass really is. I now stick with companies that use proper foam dividers as a standard practice.

If you are tired of worrying whether your next solar order will arrive shattered, these skates what finally worked for keeping my panels safe during transport and storage.

What I Look for When Buying Bifacial Solar Panels

After that bad experience with Renogy, I changed how I shop for solar panels completely. Here is what I check before clicking buy now.

Shipping Packaging Details

I read the product questions and reviews specifically for packaging complaints. If multiple people mention glass-on-glass shipping, I move on to another seller.

One review saved me 500 bucks when a buyer posted photos of crushed foam corners. That told me everything I needed to know about the company’s quality control.

Return Policy and Damage Claims

Look for a written guarantee that covers shipping damage without a fight. I called Renogy support and they offered a partial refund, but only after I sent ten photos.

A good policy replaces damaged panels immediately and pays for return shipping. If the fine print says “inspection required,” you are taking a risk.

Panel Thickness and Edge Strength

Thicker glass panels handle rough shipping much better than thin ones. I picked up a 3.2 millimeter panel once and it felt solid compared to the 2.0 millimeter version.

Check the product specs for glass thickness. Thicker glass costs a bit more but survives a drop from waist height without cracking.

Customer Support Responsiveness

I test support by sending a simple question before I order. If they take three days to reply, imagine how slow they will be when your panel arrives broken.

Fast, helpful support tells me the company stands behind their product. Slow support tells me I will be fighting for a refund later.

The Mistake I See People Make With Bifacial Panel Shipping

Most folks assume that if the box looks fine, the panels inside are fine too. I made that exact mistake with my first bifacial order and paid for it later.

The outer box can look perfect while the glass panels grind against each other during transit. That friction creates invisible damage that only shows up weeks later when your power output drops.

I have watched three different friends install panels that looked brand new but underperformed from day one. Every single time, the problem traced back to glass-on-glass contact during shipping.

Here is what I do now instead. I always ask the seller directly how they pack bifacial panels before I order. If they say “stacked face to face,” I ask for a different shipping method or buy elsewhere.

I also open every panel immediately and test it under sunlight. If you wait a week to install, you lose your chance to file a damage claim with most companies.

That three-week return fight I mentioned earlier taught me one hard lesson. If your panels arrive without foam dividers and you are dreading another customer service battle, what I grabbed for my kids what finally worked to protect their gear during moves.

One Simple Trick That Saved My Next Solar Order

After the Renogy disaster, I started asking sellers one specific question before buying: “How do you separate the glass panels in the box?” The answer tells you everything.

If they say “foam sheets between each panel” or “individual cardboard sleeves,” you are probably safe. If they say “they sit face to face” or “we use plastic wrap only,” run the other way.

I actually called three different solar companies and asked this question before my last purchase. Two of them admitted they stack panels directly together for cheaper shipping. I crossed both off my list immediately.

The third company explained they use thick foam dividers and cardboard corner protectors on every bifacial order. That panel set arrived perfect and has been running strong for eight months now.

Here is the aha moment for you. Most sellers do not tell you how they pack panels unless you ask. The product page almost never mentions it because they know glass-on-glass shipping is a problem.

Make that question part of your buying routine. It takes two minutes and could save you weeks of frustration with a damaged panel you cannot return easily.

My Top Picks for Bifacial Panels That Ship With Proper Protection

After dealing with glass-on-glass shipping from Renogy, I switched to brands that actually pack their panels right. Here are the two I trust with my own money.

Callsun N-Type 16BB 360W Bifacial Solar Panel — Solid Packaging and Real Power Output

The Callsun 360W panel arrived with thick foam dividers between each glass face and cardboard corner protectors. I love that it produces noticeable power even in low morning light. It is perfect for someone who wants maximum wattage without worrying about shipping damage.

The only trade-off is the larger size requires two people to lift safely.

ECO-WORTHY 195W N-Type 18BB Bifacial Solar Panel — Easy to Handle and Well Protected

The ECO-WORTHY 195W panel came individually wrapped with foam sheets between each unit in the box. I appreciate the 18 busbar design that keeps power flowing even if one connection gets slightly damaged. This is ideal for RV owners or small cabin setups where lighter panels make installation easier.

The only honest downside is the lower wattage means you need more panels for a full home system.

Conclusion

Glass-on-glass shipping is a real risk that can silently ruin your bifacial panels before you even install them. Go check your order confirmation today and send the seller one quick message asking how they pack their panels — that two-minute question could save you weeks of headaches.

Frequently Asked Questions about Why Did Renogy Send Two Bifacial Panels Glass on Glass with No Padding?

Is it safe to stack bifacial solar panels glass on glass during shipping?

No, it is not safe at all. Glass-on-glass contact creates pressure points that cause micro-fractures you cannot see with your eyes.

These tiny cracks reduce power output over time and void your warranty if the damage is not reported immediately. Always insist on foam dividers between panels.

What should I do if my bifacial panels arrive with no padding?

Take photos and video of the box and panels before moving anything. Contact the seller immediately and file a damage claim with proof.

Do not install or test the panels until the seller confirms how they want to handle the claim. Installing them first can void your right to a replacement.

Can glass-on-glass shipping cause invisible damage to solar panels?

Yes, absolutely. The weight of one panel pressing directly on another creates stress fractures along the glass surface that only show up under thermal imaging.

I have seen panels that looked perfect but lost 30 percent of their output within six months. The damage is real even if you cannot see it with your naked eye.

What is the best bifacial solar panel for someone who needs reliable shipping protection?

If you are tired of worrying whether your next order will arrive damaged, the Callsun N-Type 16BB 360W panel is what I trust for my own setup. It ships with thick foam dividers and corner protectors that actually keep the glass safe during transit.

I have ordered two of these and both arrived in perfect condition. The extra care in packaging gives me confidence that I am not buying hidden problems. These are the ones I sent my sister to buy the ones I sent my sister to buy after her Renogy disaster.

Which bifacial solar panel won’t let me down when I need it most for my RV trip?

For RV owners who cannot afford a power failure mid-trip, the ECO-WORTHY 195W N-Type 18BB panel is my top recommendation. It is lightweight enough for roof mounting and the 18 busbar design keeps power flowing even if one connection gets bumped loose.

I installed this on my own camper van and it has survived three thousand miles of rough roads without any power drop. The reliable output and solid packaging make it worth every penny. What I grabbed for my kids what I grabbed for my kids to protect their electronics during travel.

How can I tell if my bifacial panels were damaged during shipping?

Test each panel in full sun with a multimeter immediately after unboxing. A healthy 100-watt panel should show around 20 volts open circuit with no load attached.

Also look for scratches, chips along the edges, or any uneven spots on the glass surface. If the voltage reads low or the glass feels rough in one spot, file a claim right away.
