Solar panels on rental balconies mount with adjustable clamps to the railing, connect through a microinverter (included with most kits), and plug into any standard 120V outlet on or near your balcony. No drilling, no wiring, no electrician, and no building modifications needed. Setup takes 30-60 minutes.

Yes. Most renters run the solar cable through a slightly open sliding door or window. Flat solar cables (available for $10-15) are designed to fit under closed doors and windows without damage. Some kits include these flat cables. This is the most common setup for apartments without outdoor outlets.
Glass-panel balconies can't support clamped solar panels. Instead, use a freestanding frame (weighted with sandbags) to prop the panel on the balcony floor, or mount a flexible panel to the glass using suction cups. BougeRV's flexible panels are popular for glass balconies.
Yes, but with reduced output. Winter production is typically 40-60% of summer production due to shorter days and lower sun angle. However, snow reflection can actually boost output on clear winter days. Annual averages already account for seasonal variation in the savings estimates above.
