City lease, tiny balcony, zero roof rights? You can still slash your power bill and charge laptops, ebikes, and backup batteries with the sun. Renewable-energy designer Lydia Carver turns complicated electrical jargon into a weekend DIY that slips past HOA rules and municipal inspectors alike.

• Gear that passes inspection - UL-listed folding panels, micro-inverters with NEC-2023-ready plug-locking cords, and fire-safe LiFePO₄ packs.
• Patio math, not roof math - calculate watt-hours for a 4×8-foot railing, pick the right tilt stand, and avoid wind-load fines.
• No-permit hookup - step-by-step photos for plugging into a dedicated GFCI outlet without hard-wiring the breaker box.
• Code cheatsheet - the six clauses that matter (NEC 210.8, 690.12, etc.) and the exact phrases to quote when your landlord balks.
• Performance hacks - shade-tolerant cell layouts, heat-gap mounting tricks, and the smartphone apps that boost daily harvest by up to 22 %.
• Budget paths - build it for $350 with big-box parts, or splurge $1 k for a suitcase unit that powers a fridge during blackouts.
• Scale-up options - daisy-chain neighbors' arrays into a legal micro-grid when the whole block loses power.

Success stories from Chicago high-rises, Miami hurricane zones, and Tokyo micro-apartments prove that solar freedom no longer requires a suburban roof-or a permit maze.
