The TPL M-48 Series of photovoltaic panels is a solution designed to maximize energy yields on surfaces with limited space. The use of advanced PERC cell technology allows for significantly more efficient conversion of solar radiation, which translates into stable system operation even in poor lighting conditions. What particularly distinguishes these modules from the competition is their compact dimensions, resulting from the use of 48 high-efficiency monocrystalline cells. Thanks to the smaller format, installation designers gain great freedom in arranging panels on complex roof surfaces with numerous obstacles, such as chimneys or roof windows. The TPL M-48 series guarantees high resistance to mechanical loads, which ensures many years of trouble-free operation in variable weather conditions. This product perfectly meets the needs of single-family homeowners and small commercial facilities, where optimizing roof space utilization while maintaining the aesthetic appearance of the entire installation is key. By choosing this series, the user receives a product combining modern materials engineering with a practical approach to installation, which effectively shortens the return on investment by eliminating surface losses occurring with standard, larger modules.

About the TPL M-48 Series series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What is the maximum power output of the TPL M-48 Series panels?
The TPL M-48 Series panels reach a maximum power output of up to 225 Wp. This is lower than standard 60- or 72-cell modules, but it results from the compact dimensions of a panel built on 48 monocrystalline cells. This gives the module a higher power density relative to its surface area compared to older designs of similar format.
Are TPL M-48 panels suitable for roofs with many obstacles, such as chimneys or roof windows?
Yes, this is the main purpose of this series. The smaller format, resulting from the use of 48 cells, makes it easier to arrange modules on complex roof slopes, where standard, larger panels would create significant surface losses. This allows better use of available space on single-family home roofs.
What is the warranty on the TPL M-48 Series panels?
Manufacturer TPL Solar provides a 12-year product warranty and a 30-year power output warranty. This means protection against both material and workmanship defects, as well as a guarantee of maintaining a specified energy production level over the long term, typical of modern PERC modules.
How does the PERC technology used in the TPL M-48 differ from standard silicon cells?
PERC (Passivated Emitter and Rear Cell) technology adds a passivation layer on the back of the cell that reflects unused photons back into the cell. This increases solar energy conversion efficiency, especially under weaker light conditions such as morning, evening, or cloudy days, resulting in higher energy yields compared to standard cells.
Are the TPL M-48 panels bifacial?
No, the TPL M-48 Series uses monofacial monocrystalline modules based on PERC technology. The panel captures sunlight only from the front side, which is a standard and proven solution for typical roof installations where the rear side of the module has no access to additional reflected light.
Who manufactures the TPL M-48 Series panels and is it a Tier 1 manufacturer?
The TPL M-48 Series panels are manufactured by TPL Solar, headquartered in Pakistan. The manufacturer is not listed as Tier 1 under the Bloomberg NEF classification, which is worth considering when comparing with brands with a longer track record and larger production scale, though this does not by itself determine the technical quality of the modules.
