Thanks to Staff Member
Izzy138 for finding this deal.
Features:
- HPBC Technology
- ECO 200W panels use P-TYPE technology solar cells, with a maximum conversion rate of up to 25.2%,use a grid-free all-black design to absorb sunlight in all directions, making them ideal solar panels for home roof installation
- With busbar-free design, HPBC solar cells do not have busbars blocking the front, allowing the solar cells to absorb 100% sunlight and have a smaller surface area at the same power
- Suitable for most roof colors, black solar panels make your roof look more beautiful and display a technological atmosphere. Each solar panel generates an average of 800Wh of electricity per day, making it perfect for installation on the roof of your mansion
- ECO-WORTHY 200W panel size: 51.18 x 26.4 x 1.4 inches (1300 * 670 * 35mm), weight 21 pounds. The diode is pre installed in the junction box with a pair of pre installed 2.95-foot cables
- Equipped with IP68 protection rating, can withstand decades of rain and snow, and uses low-iron tempered glass and corrosion-resistant aluminum frame to ensure excellent performance in all weather conditions.

HPBC solar panels are a high-efficiency solar cell technology that moves all electrical contacts to the rear of the cell, which maximizes the front surface area for sunlight absorption and offers a clean, sleek aesthetic. This design increases power generation, enhances durability, and improves performance in various conditions, making it a competitive alternative to traditional technologies like PERC solar cells.

The installer grade panels DESTROYED performance of these, but for a smaller 200w panel I am still happy with the 195w bi-facials I had from them, these all black panels honestly I am probably just going to give away.
Here is a demo of the new battery setup

Its a much more complex topic than a simple answer though because it actually depends on how the shade falls on the panel more than how much shade. If you covered just one section it would trigger the internal bypass diode. But if a piece of shade went across all the seconds depending on the amount of shade it can bring the panel down to its knees.
The other main way to fight shade is more than one panel in parallel.
There are some new panels like Renogy that are specifically marketed to fight shade, but I have not tested on in person yet, probably just added some extra diodes and more bus bars th an you normally see on a small panel (more akin to what you see on a large installer grade panel, and one reason they do so much better in performance)
If your wiring in parallel they need the same voltage or close, if your wiring in series they need the same current or close.
This is one of the next topics I cover soon in my Solar 101 course (Free on YouTube) after I go over Over paneling in the next class.
There is exact math for this, its not guess work. You can know before you buy how well it fits and if its a perfect match, or calculate your losses.
I have two different panels on my roof, I am running them to separate MPPT to avoid any losses, but I did pick them so that in a worst case I only use 1.5% if I mix them.
