01 Why We Focus on Old-Model Solar Panels

As the solar industry evolves, many panels go out of production faster than systems reach their end of life.
But for installers, even one damaged or degraded panel can affect the entire system’s output.

That’s where GBP Direct comes in.

We specialize in replacement solar panels that faithfully reproduce the same:

Output Capacity
Dimensions and thickness
Mounting hole positions and inner diameters

This means you can replace old panels without modifying the structure of your array — saving both time and cost.

And the best part? Our replacement panels have already reached over 300,000 units sold (as of July 2025) to satisfied installers across Japan and beyond.

02 Now Supporting 300 Models from 80 Manufacturers

From major international brands to niche makers, our lineup now includes panels from:
Trina Solar, Canadian Solar, LONGi Solar, Jinko Solar, JA Solar, Panasonic, Sharp, Mitsubishi Electric, Hanwha, Risen Solar , and more.

So whether you’re maintaining a large commercial project or replacing a single rooftop panel, you’ll have more options to choose from than ever before.

03 How to Find the Right Replacement Panel

Ordering from GBP Direct is simple:

1.Enter your model number in the search bar.

2.Check the spec sheet and technical drawing for compatibility.

3.Add to cart — orders start from just 1 panel.
(For bulk orders over 40 panels, we’ll provide a separate quotation.)

4.Once payment is confirmed, panels are produced to order — delivery time is around 3 months.

💡 Even if the dimensions differ slightly, your panel might still fit depending on your racking setup.
