Solar panels for a tiny house – what you need to know
Every one of our models is pre-prepared for solar panel installation. But how many do you need, how big a battery, and what does it cost? We’ve calculated it for you.
How many solar panels does a tiny house need?
| Model | Max. panels | Max. output | Covers |
|---|---|---|---|
| Tiny house 5–7 | 5–6 pcs | 2.64–3.96 kW | 2–4 people, summer |
| Tiny house 8–9 | 6–7 pcs | 3.96–4.62 kW | 4–6 people, spring–autumn |
| Tiny house 11 (Titan, Prime) | 9 pcs | 5.94 kW | 6 people, year-round |
| Tiny house 48 (fixed) | 13 pcs | 8.58 kW | Family living |
How does the system work in practice?
- A summer day: The panels generate 20–40 kWh, the tiny house’s consumption is 3–8 kWh. The surplus charges the batteries.
- A winter day (overcast): The panels generate 1–5 kWh. Backup: a wood stove + batteries.
- Night: Power comes from the batteries (recommended capacity: at least 5 kWh = 2 EcoFlow Delta Pro batteries).
Recommended setup for year-round off-grid operation
- 9 × 660W panels (5.94 kWp) – for 11m models
- A 6 kW hybrid inverter/controller (Victron Energy or Huawei SUN2000)
- 3–4 LiFePO4 batteries, totaling 10–15 kWh (EcoFlow, BYD, Pylontech)
- A backup wood or pellet stove
Indicative installation price
- 6 panels + a hybrid inverter + a 5 kWh battery: ~CZK 120,000
- 9 panels + a hybrid inverter + a 10 kWh battery: ~CZK 200,000
- A full off-grid set for the Titan 11: ~CZK 300,000–400,000
Monitoring and managing the solar system
Modern hybrid inverters (Victron, Huawei, Deye) offer a mobile app for monitoring generation and consumption in real time. At a glance you can see: panel output, battery status, household consumption, and surplus. Our customers greatly appreciate the peace of mind this monitoring brings – you know exactly how much energy you have left for the night.
Solar panel maintenance
Solar panels are practically maintenance-free. We recommend:
- Rinsing with a hose twice a year (spring + autumn) to remove dust and bird droppings
- A visual check of the frame mounting after strong wind
- Checking cables and connectors every 2–3 years
Solar panel subsidies
A subsidy from the New Green Savings (Nová zelená úsporám) programme can be drawn for a solar installation on a tiny house (if the tiny house is a fixed structure). Subsidies generally aren’t available for vehicles – check current conditions at novazelenausporam.cz.
