What goes into a system

The four components every system needs

Whether you buy a bundled kit or source your own, every plug-in solar setup has the same four pieces.

☀️
Solar Panels
Typically 250W–400W per panel

250W panels are easier to handle and ship cheaper. 400W panels generate more per unit but are larger. Panel prices vary significantly — check current market pricing before buying.

Price varies — check current listings before assuming any figure
⚡
Microinverter
Typically $150–$300; UL 1741 certified

Converts DC power from your panels into AC electricity your home can use. The APsystems EZ1-M is the most widely used US model (~$150–$180). The EcoFlow STREAM is a newer alternative at ~$299. Look for UL 1741 certification and built-in WiFi monitoring.

Est. cost: $150–$300 depending on model
🔗
MC4 DC Cables
10 AWG, weatherproof, pre-terminated

The cables that connect your panels to the microinverter. Pre-terminated with MC4 connectors — no splicing required. Rated for outdoor UV exposure.

Est. cost: $20–$30
🔌
Feed-In Safety Plug Cord
NEMA 5-15, with safety interlock

The cord that connects the microinverter output to your wall outlet. Uses a safety plug design with a physical interlock. Required by law in several states.

Est. cost: $25–$40
A note on pricing

What does a system actually cost?

The honest answer: it depends a lot on where you buy and when.

The real picture

$500–$1,500+
Typical all-in range · Varies widely by configuration
Panels (biggest variable)Check current market pricing
Microinverter (APsystems EZ1-M or EcoFlow STREAM)~$150–$300
Cables, plug cord, connectors~$40–$70
Mounting hardware~$30–$100+ (varies)
Bundled kits (all-in)$900–$2,500 from established sellers
Panel prices are the most volatile input. New 400W panels currently run $150–$200+; secondhand bifacial panels can be found for less on OfferUp and Facebook Marketplace.
How to buy

Bundled kit vs. sourcing your own

Two approaches, each with real tradeoffs.

✅ Bundled kit (e.g. PluggedSolar, Bright Saver)

  • Everything arrives together, designed to work as a system
  • Less research required — components are already matched
  • Usually includes some form of customer support
  • You know the total cost upfront, including shipping
  • Higher per-watt cost than self-sourcing in most cases

🧡 Self-sourced components

  • Potentially lower cost, especially if you find panels secondhand
  • More flexibility — choose panel size based on your space
  • Requires more research to ensure component compatibility
  • Shipping panels separately adds cost and complexity
  • No bundled support if something doesn't work
