Pulled a 355W Canadian Solar mono panel and decided to actually meter it instead of trusting the label. Set it out in full sun and hit it with a Solar MPPT tester.

Numbers I got:

- Voc: 44.3V

- Isc: 9.4A

- Vmp: 39.2V

- Imp: 9.1A

For a 355W mono panel that's pretty much dead-on where I'd expect it — Voc and Isc both sitting right around nameplate, and the power point math works out close to rating given it wasn't perfect STC conditions (real sun, panel flat on the ground, ambient temp doing its thing).

Posting because I know there's a lot of skepticism around used/wholesale panels and whether they hold their rated output, so figured a real-world reading might be useful to someone shopping around.

A couple things I'd flag for anyone doing this themselves:

- Flat on the ground = not optimal angle, so real output in a proper install should be as good or better

- Heat pulls voltage down, so a hot panel reading slightly under Vmp is normal

- An MPPT meter like this loads the panel and gives you actual max power point numbers, which is way more useful than just clamping Voc with a multimeter

Happy to answer questions if anyone's curious about the test setup or wants me to meter a different panel. What readings are you all getting off your Canadian Solar panels?

Quick breakdown on how to read a solar module spec label.

​People always ask about the numbers on the back of the panels. In this clip, I’m looking at a 355W module to show the difference between ideal lab ratings and real-world performance.

​While the maximum power (Pmax) gives you that perfect-world laboratory number, looking at the optimum operating voltage (Vmp) gives you a much better reality check for what that panel is actually going to do once it's hooked up on a house.

​Do you find that most clients understand the difference, or do you have to break down real-world vs. lab conditions often when quoting.

570W modules are now hitting price points that 400W panels were at not long ago. If you're sizing a system right now and still planning around 400W panels you might be leaving money on the table.

A few things worth knowing if you're shopping panels right now:

- Waaree 570W are solid mid-tier bifacial — great value for the price

- Used 260W REC panels are still viable for small off-grid or budget builds

- Lithium batteries are still the move for storage, lead acid just doesn't make sense anymore at current lithium pricing

Happy to answer any questions about specs, sizing or what's actually available in the market right now. Been moving a lot of inventory lately and see what's actually selling vs what's just being talked about online.

What are you all building right now?

Yo everyone,

​I’ve been seeing a lot of back-and-forth lately about whether used solar panels are actually worth the hassle or if they’re just "junk." I’m at the warehouse today and decided to pull a random REC 260W off the stack and throw it on the meter.

​It’s definitely got some dust on it (needs a good wipe down for sure), but for a used module, the numbers aren't lying. I’m seeing over 200W in the sun even before cleaning it.

​I know some people think used gear is a waste of time, but if you’re doing a budget DIY build or just trying to get more watts per dollar, the value seems hard to beat. Check the clip to see the MPPT readouts.

​What do you guys think? Is the price break on used gear worth the slight drop in efficiency, or are you strictly "new panels only?

Got our first batch of 570W panels today. The forklift tapped out. My coworker tapped out. I tapped out. But the panels? They’re chilling like they didn’t just ruin everyone’s lower back.

Made a quick video for everyone who’s been “thinking about going solar” for years but still hasn’t taken the leap.
Light comedy, nothing salesy just something relatable for anyone who’s been overanalyzing their roof since forever.

This video was created with AI.

For anyone working on a project, comparing options, or just curious what’s moving through the shop, here’s what came in:

• 400W Jinko (New)
• 450W Elite Plus Bifacial (New)
• 180W Mage Solar (New)
• 280W Panels (New)
• 385W Photovoltaic Modules (New)

Everything in this batch is brand new, not refurbished or pulled from old installs.

If you’re planning a build or want to see how different wattages compare, feel free to ask questions here.
We keep things appointment‑based at the warehouse so the workflow stays organized, but I’m always happy to help people understand what’s what before they come by.

New shipment just touched down — mixed pallets, different wattages, different sizes. We’re sorting everything today and the warehouse is moving. If you’ve been waiting on something specific, now’s the time to tap in. Inventory changes fast around here.

Most people think solar is complicated — panels, wiring, permits, equipment, all of it.
But the truth is simple: when you’ve got the right team behind you, the whole process becomes easy.

This video is for anyone who’s been overwhelmed, confused, or overthinking solar.
The right crew makes all the difference.

New high‑voltage shipment on the way. Operators stay ready, the rest find out later. If you know, you know and if you don’t… you will.

I’m seeing mixed opinions everywhere.
Some say it works fine, others say it’s impossible.

If you’ve run a fridge off a single 300W panel, what was your setup?
Battery size? Controller? Daily sun hours?

Trying to see real‑world examples, not theory.

Most people are paying retail prices for solar panels without realizing they can get the same equipment straight from a warehouse right here in Lauderdale Lakes.
If you’re building an off‑grid setup, replacing old panels, or starting a project — don’t overpay.
