Why ground the module frame?

Prevents electric shock from insulation failure, not just lightning protection.

Do modules really last 25 years? What should I check in the warranty?

Yes, but with degradation. Product warranty: usually 10-12 years (defects). Power warranty: 25 years- compare linear power guarantee.

Does tilt/orientation matter a lot?

Yes. Optimal tilt equals to local latitude; true south (northern hemisphere) is best. North-facing kills output.

Why do some N-type modules (TOPCon, HJT) perform better in low light?

Higher internal resistance and better low-light response. They produce power earlier in the morning and later in the evening than P-type modules.

Product Q&A

Q:New modules lost power quickly - is it a defect?

Likely UVID (UV-induced degradation) or a metastable state.This is temporary - N-type modules often recover after more sunlight exposure. Not a permanent failure.

Q:What causes a hot spot (burning smell, local heating)?

Hot spotting - caused by shading (bird droppings, leaves) or a cracked cell. Can lead to glass cracking or fire. Clean the module; if still hot, replace the affected cell/module.

Q:Are microcracks (invisible cracks) dangerous?

Yes - they reduce power output and can develop into hot spots. Avoid stepping on modules during installation. Replace if severe cracks are found via EL testing.

Q:What are edge bubbles on glass-glass modules?

Edge delamination - poor lamination or material failure. It lets moisture and air in, which can cause arcing (fire risk). Ask for DH (damp heat) test reports before buying.

Q:Snow - leave it or remove it?

Remove it - snow blocks power and adds weight. Use a soft plastic shovel or brush. No metal tools.
