The Shelly, a tiny house attributed to Tiny Solar Homes, combines a reported usable length of about 7 m (nearly 23 ft) with a triple-axle trailer and a roof-mounted solar array connected to a battery in an exterior storage box. That makes it trailer-based and solar-equipped; it does not, by itself, establish that the home is certified for road use or can operate indefinitely without utility hookups.
What the Shelly’s reported setup includes
New Atlas reported the Shelly as a tiny house designed for two, built on a triple-axle trailer with about 7 m (nearly 23 ft) of usable length. Its account also describes roof-based solar panels connected to a battery unit housed in an exterior storage box. An outdoor deck is mentioned as an optional extra, not as a confirmed standard inclusion. New Atlas’s March 22, 2025 article is the source for these details.
Those details sketch the concept, but do not amount to a complete construction or operating specification. The available report does not state the floor plan, usable floor area, solar array wattage, battery capacity, expected runtime, water storage, or wastewater system. It also does not give a current price.
What “off-grid” can—and cannot—tell you
Off-grid describes how a dwelling is intended to access utilities; the term alone does not tell you how much energy or water it can supply, or for how long. For the Shelly, the reported solar panels and battery establish a basic power arrangement, but without panel and battery capacities or an estimate of the home’s loads, its practical autonomy cannot be assessed.

#1 Best Overall
System sizing is specific to a home and its site. As general context—not a Shelly specification—KYRAX Homes says its full off-grid packages are sized at design time according to the site and loads. That is a useful reminder to request a system design tied to actual appliances, occupancy, climate, and expected use rather than assuming that “solar-powered” means uninterrupted power in every condition. KYRAX Homes’ off-grid tiny homes information describes its own offerings.
Does the trailer make it road-ready?
A triple-axle trailer is a reported physical feature, not proof of road certification, legal registration, or permission to tow in a particular place. The Shelly report does not provide a loaded weight, axle or trailer ratings, braking details, certification, or tow-vehicle requirements. Those figures and documents matter because a buyer needs to know whether the completed home can be towed safely and lawfully on the intended route.
Rank #2
Rules vary by jurisdiction, and a trailer’s legal status can also differ from rules governing where a tiny house may be parked or occupied. Confirm the requirements with the relevant transport and local authorities for the intended location; do not infer compliance from the phrase “road-ready.”
What to verify before committing
Ask Tiny Solar Homes for a current specification sheet and written quote covering the exact configuration being offered. In particular, establish:
- Price and inclusions: whether the quote includes the complete solar and battery system, and whether the deck is an extra.
- Power: solar panel wattage, battery chemistry and usable capacity, inverter details, and an estimate of runtime for the proposed loads.
- Trailer and towing: loaded weight, axle ratings, trailer rating, brakes, certification or inspection documents, and the required tow vehicle.
- Water and waste: water storage and supply arrangements, wastewater handling, and any other utility systems included.
- Location: where the home can be registered and towed, and the rules for placing and occupying it at the intended site.
These details determine whether the Shelly fits a particular project; they are not established by the published description.

Specifications from another builder can show what a more detailed listing looks like, but they cannot fill gaps in the Shelly’s description. For example, Tiny House Building Company lists a separate Croft model with a 2,000-watt solar system, a battery bank, propane appliances, and a 42-gallon water tank. Those figures belong to the Croft, not the Shelly. Tiny House Building Company’s Croft Model page identifies that separate offering.
For a meaningful comparison, seek matching details for each home: usable floor area and total length; loaded weight and trailer capacity; certification and registration; tow-vehicle needs; solar and usable battery capacity; water and wastewater systems; sleeping layout; included versus optional equipment; and delivered price. The Shelly’s available description supports only a subset of those points, so a feature-by-feature judgment would require additional specifications.
