Saves $38–$130 a year, depending on the state you are in. Your state, your rate →
A panel hanging upright on a south-facing railing, unshaded, at your state's average power rate (NREL and EIA data).
In the box: 2 × 200 W DC flexible panels, Hoymiles 391 W AC microinverter, AC cord, stainless zip ties, quick-start guide. Space for two 57 × 27 in panels.
Free shipping in the US, except NY, ME and VT. Arrives in two boxes.
30-day returns: 10% restocking fee, return shipping paid by you.
Grid-connected solar offsets electricity while the sun shines. It does not supply backup power during an outage.

Before installation, check your state, utility and property requirements.
Pick this one if your home uses more during the day: a second fridge, a home office, an aquarium. Two panels on one inverter means more power on cloudy days and in winter too.
Hanging on a south-facing railing, the 400 makes 290 to 460 kWh a year depending on your state. See what it saves where you live.
Nothing to buy separately. Nothing to wire.
Start with the sunny space you have: the difference is one panel or two. The 400 W kit's extra $200 buys a second 200 W DC panel, which needs its own space. Both kits share the 391 W AC inverter, so the output limit is the same.

Panel wattage is the DC rating; inverter output is AC. Actual generation depends on sunlight, orientation and shade. Estimate savings for your home.
A railing, deck, patio, fence or sunny wall. Measure space for each panel, check for shade and plan a secure mounting position near a suitable outdoor GFCI outlet. No extension cord or power strip.
Choose a sunny position. Before mounting, complete any required utility notification, approvals and property permissions.
Follow the quick-start guide to secure the panels and connect the inverter and cord.
Once the required local steps are complete, connect to the suitable outlet and see generation in the Hoymiles app. The guide includes utility notification text where needed.
