Efficiency (18-22%)

Higher efficiency means more power from limited balcony space

Durability (25-year warranty)

Weather resistance and long-term performance guarantees

Size & Weight

Compact panels that fit balcony railings without overloading

Price per Watt ($0.50-$1.00)

Balance between quality and affordability for ROI

Pro Tip

For balcony systems, always choose monocrystalline panels. The higher efficiency is crucial when space is limited. Calculate your exact ROI with our free calculator to see which panel size works best for your location.

Frequently Asked Questions

Q: How many panels do I need for a balcony system?

A: Typically 2-4 panels (400W-800W total). Most balconies can fit 2-4 × 200W panels. Use our calculator to determine the optimal size based on your energy needs and balcony space.

Q: Do I need to match panel brands?

A: Not necessarily, but it's recommended. Panels with similar voltage and current ratings work together. Mixing brands is possible but may reduce overall efficiency slightly.

Q: What's the difference between 200W and 400W panels?

A: 200W panels are standard for balcony systems (smaller, lighter). 400W panels are larger and heavier, making them harder to mount on balconies. Most balcony systems use 2-4 × 200W panels instead.
