Which Solar Panel Should You Choose? Explore A2Z’s Range

Your roof, the appearance you want and the complete system matter as much as the wattage printed on a panel. A2Z’s selection includes 15 listed models from 415 to 640 W. Here is how to turn those options into a shortlist that fits your needs.

Start with the place where the panels will work

Black frame, Full Black or glass-glass?

Black frame describes the frame finish. Full Black describes a more uniform dark appearance across the module. The list includes 450 W black-frame options, a 415 W Full Black model and a 460 W Full Black glass-glass model.

G2G means glass-glass: glass on both sides of the module. It describes construction, while Full Black describes appearance. One panel can have both features, as the listed TT460-96TNB12R-G2G does. For your roof, we compare the exact module weight, mounting requirements and finish together.

Bifacial means a panel can also use light reaching its rear. It is a separate performance characteristic, not another word for glass-glass. For the confirmed bifacial version, rear shading, clearance and the surface underneath influence the benefit; a close-fitting roof installation should not be sold a fixed extra-yield percentage.

The complete 15-model selection

Use the exact code when requesting an offer. Models with the same wattage can have different finishes, construction or configuration. The -Y and G2G variants remain separate products.

Which options would we shortlist for you?

For a home where appearance matters: compare the 415 W Full Black, the 450 W black-frame models and the 460 W Full Black G2G. Then choose using the roof layout, desired finish and complete offer.

For a clear commercial roof: start with the 595–620 W choices. Compare the standard and G2G versions where listed. For example, CWT600-144TN10 and CWT600-144TNB10-G2G both carry a 600 W rating, but they are different module configurations.

For a larger site: include the 635 W and 640 W G2G models. Higher rated power per module can reduce module count for a target capacity, provided the physical layout and electrical design suit the selected product.

How much can panel count change?

For a simple target of at least 6 kWp of rated panel capacity, 14 × 450 W gives 6.30 kWp, 10 × 605 W gives 6.05 kWp, and 10 × 640 W gives 6.40 kWp. These totals are different; this comparison shows how module count changes across the selection.

These are arithmetic examples, not roof layouts or wiring plans. Fewer panels do not automatically mean less roof area or lower installed cost. Compare the usable layout, mounting and total offer. Rated kWp is also different from daily kWh production.

Will the chosen panel work with your inverter?

Check the exact panel’s voltage and current against the inverter’s inputs before deciding the connection arrangement. Series adds voltage; parallel strings add current. Matching total watts alone is not enough.

Let A2Z narrow the choice for you

Send your country, roof or ground dimensions, a few site photos, preferred appearance and intended use: on-grid, off-grid, hybrid or irrigation. If you have an inverter already, include its exact model. We can compare two or three relevant panel options and prepare a focused offer with the agreed specification and supply origin.

For installers and distributors, add your target quantity and preferred model codes. If Türkiye manufacture is part of your requirement, state it in the enquiry so the selected model and origin are explicit in the quotation.
