Get two solar panels for the price of one! 460 W for the price of 230 W.
Meet the TESUP Flex Solar Panel — 230 W of monocrystalline output in a panel thin and flexible enough to mount on a vehicle roof, boat deck, motorhome, shed, balcony, tent, or any curved surface a rigid panel can't reach.
Every order ships as two panels in one carton — 460 W of combined solar capacity for the price of one delivery.
Key specs (per panel)
- Peak output: 230 W at STC (1000 W/m², AM1.5, 25 °C)
- Output density: 230 W per square metre — roughly 1 m² per panel
- Cell type: high-efficiency monocrystalline silicon
- Front sheet: ETFE — anti-reflective, self-cleaning, UV-stable
- Build: flexible laminate, no aluminium frame, no glass cover
- Mounting: corner eyelets at all four corners (for hooks, screws, rope, or zip-ties) plus pre-applied double-sided adhesive tape on the back — install on windows, walls, vehicle roofs, boat decks, or any flat or curved surface
- IP-rated waterproof — safe for permanent outdoor installation
Two panels for one delivery price — and here's the honest reason
A single 230 W flexible panel doesn't fill our standard shipping carton — there's free space left over. Instead of shipping air, we put a second 230 W panel in the same box. You pay one delivery, but you receive 460 W of combined solar capacity at your door. Wire the pair in series for a 24 V / 48 V battery bank, or in parallel for a 12 V system.
How solar output varies with the sky
Photovoltaic output is roughly linear with solar irradiance — the sunlight power reaching the panel surface, measured in watts per square metre. The chart below shows the output of a single 230 W panel across typical sky conditions, from full midday sun down to heavy overcast.
Flex Solar Output Curve
| Sun condition | Irradiance | Output | Visual | Note |
|---|---|---|---|---|
| Full midday sun (STC) | 1000 W/m² | 230 W | peak per panel | |
| Light cloud / hazy sun | 700 W/m² | 160 W | productive daylight | |
| Early or late sun | 500 W/m² | 115 W | morning / evening | |
| Bright overcast | 400 W/m² | 90 W | cloudy day | |
| Heavy overcast | 200 W/m² | 45 W | low-light yield |
Output measured per panel at 25 °C, Standard Test Conditions (STC). Every order ships as two panels in one carton — 460 W combined peak. Real-world yield depends on orientation, tilt, temperature and shading.
What 460 W of solar can power
- Power your home from windows or walls — mount the pair on south-facing windows or external walls and feed the household battery
- LED lighting + Wi-Fi router + laptop — full day, off-grid
- 12 V / 24 V fridge in a van or boat — continuous, with battery buffer
- Top-up charging for a household battery bank or e-bike fleet
- Pairs perfectly with a TESUP wind turbine for a solar + wind hybrid

Flex Solar Panels — Frequently Asked Questions
Honest answers on output, payback, mounting and grid connection.
It depends on your local sunshine, roof angle and shade. The 460 W Flex kit produces a few hundred kWh per year in cloudier climates and considerably more in sunny countries. Use the "Will they pay for themselves?" calculator on this page to estimate the output from your local daily sun-hours.
At your local electricity price of about $0.18/kWh and the $999 price, payback depends mainly on how sunny your location is — sooner in sunnier regions and with good roof orientation. After that the electricity the panels generate is effectively free, and rising prices shorten the payback. Use the calculator on this page for an estimate from your local sun-hours.
Almost anywhere a rigid panel cannot go. Flexible panels are thin, light and bend to a curve, so they suit caravans, motorhomes, boats, sheds, garden buildings and curved or weight-sensitive roofs. They glue or fix down flat with no heavy frame or roof penetrations.
Flexible panels are far lighter and thinner and can follow curved surfaces, making them ideal for vehicles, boats and roofs that cannot take a heavy framed panel. Rigid panels are a little more efficient per square metre, but flexible panels win wherever weight, height or a curved surface matters.
Yes. The Flex panels are designed for grid-tied (on-grid) use with a compatible inverter and cabling, so they offset the electricity your home draws and, where your supplier allows, export surplus. A charge controller and battery are not required for on-grid use.
They are built for years of outdoor use and need almost no maintenance — an occasional rinse to clear dust or leaves keeps them at their best. With no moving parts, there is nothing to wear out.
