Three Steps. That's It.
No contractors, no permits, no electrical work. Plug-in solar is as simple as setting up a new appliance.
Place
Position solar panels on your balcony railing, patio, backyard, or any sunny spot. No roof access needed — no drilling, no mounting hardware on the structure.
Plug
Connect the system to any standard wall outlet. The built-in microinverter converts DC to AC and safely feeds clean energy into your home circuits — no electrician required.
Save
Start generating your own electricity immediately. Your meter slows down, your bill drops, and with battery storage you also get backup power during outages.
Solar & Energy Storage Solutions Compared
Understand the key differences between plug-in solar, portable power stations, and traditional rooftop systems. Each serves a different need — and a different budget.
Plug-in solar pushes power into your home circuits through standard wall outlets. Multiple plug-in solar units can mesh-network together for expanded capacity. The system reduces your utility meter in real-time and provides backup power during outages.
Why Plug-In Solar?
Four reasons millions of households are switching to plug-in solar energy systems.
Direct Energy Savings
Generate free electricity from sunlight. A typical 800W system produces 3–5 kWh/day, saving $200–$600/year depending on your state's electricity rate. Most systems pay for themselves in 2–4 years — then save for 25+ more.
Backup Power & Resilience
With battery storage, keep your essentials running during outages — refrigerator, Wi-Fi, phone chargers, medical devices. The average US household faces 7+ hours of outages per year. Plug-in solar is the only backup power option that also saves you money every day.
Environmental Impact
An 800W plug-in system offsets roughly 0.5–1.0 tons of CO₂ per year — equivalent to planting 15–25 trees. Clean energy with zero emissions, zero noise.
Portable & Flexible
Take it with you when you move. No permanent modifications to your home. Start with one panel, add more anytime. Scale from 400W to 3,000W as your needs grow.
Two Benefits. One System.
Plug-in solar delivers value in two distinct ways — every day savings on your electricity bill, and backup power when the grid goes down. Here's how each benefit works.
Bill Savings
Every watt of solar power your system generates is a watt you don't buy from the utility. Your electricity meter slows down in real time — reducing your monthly bill by $15–$50 depending on your system size and local rates.
- →Offsets the most expensive peak-rate electricity first
- →Typical savings: $200–$600 per year for a 400–800W system
- →Payback period: 5–8 years at average US rates
- →Works best in states with high utility rates (CA, NY, HI, MA)
Energy Resilience
Add a battery to your plug-in solar system and you have stored energy ready when the grid goes down. Unlike a generator, it's silent, requires no fuel, and recharges automatically from your solar panels during daylight.
- →1,000Wh battery powers a fridge for ~12 hours or a phone for 80+ charges
- →Recharges from solar panels during the day — no grid needed
- →Silent, zero-emission backup vs. noisy gas generators
- →Critical for renters who can't install whole-home backup systems

Who Is Plug-In Solar For?
Whether you rent, own, or manage property — there's a plug-in solar solution for you.
Industry Opportunities
Plug-in solar creates new business opportunities across the energy ecosystem.
Apartment Complexes & Property Managers
Offer plug-in solar as a building amenity. No structural modifications, no liability. Attract eco-conscious tenants, improve ESG scores, and differentiate your property.
Retail Energy Companies
Bundle plug-in solar + storage with electricity plans. Reduce peak demand on your grid, increase customer retention, and create a new revenue stream.
Electricians & Contractors
Add plug-in solar installation and consultation to your service offerings. No special license required — these are plug-and-play systems.
Solar Installers
Use plug-in solar as an entry-level product to build customer relationships. Convert balcony solar customers into full rooftop installations when they're ready.
Safety & Standards
Plug-in solar systems meet rigorous electrical safety standards. Here's what protects you.
UL 3700 is the definitive US safety standard for plug-in grid-interactive power systems. It covers anti-islanding, ground fault detection, overcurrent protection, and power quality. Utah's HB 340 requires UL 3700 certification, and virtually all pending state legislation references it. Always verify UL 3700 certification before purchasing any plug-in solar system.
All grid-connected microinverters must meet UL 1741 standards for utility-interactive inverters, ensuring safe grid integration and anti-islanding protection.
If the grid goes down, the microinverter automatically disconnects within 2 seconds — protecting utility workers and preventing back-feeding. This is required by both UL 3700 and UL 1741.
Plug-in solar systems fall under NEC Article 690 (Solar Photovoltaic Systems) and Article 705 (Interconnected Power Production Sources). Systems below utility interconnection thresholds with anti-islanding protection operate within existing NEC provisions without requiring utility approval.
While plug-in solar systems can operate on shared circuits, best practice is to use a dedicated 20A circuit for optimal performance and safety. A dedicated circuit ensures the full circuit capacity is available for solar input and avoids potential nuisance tripping from shared loads. Some state bills may require a dedicated circuit — check your state's specific requirements.
Built-in GFCI protection monitors for ground faults and shuts down the system instantly if any leakage current is detected.
Because plug-in solar requires no structural or electrical modifications, most homeowner and renter insurance policies cover them as personal property.
Outdoor-rated panels and inverters are sealed against rain, dust, and humidity. Designed to operate safely in all weather conditions year-round.
