FlexWatt BP · Modular solar panels
Plan your solar setup, one panel at a time.
Choose 450W or 900W of rated solar-panel capacity for your planned installation. Each configuration uses 225W monocrystalline modules, with clearly defined per-panel dimensions and electrical ratings to help you check the available space and equipment compatibility.
Made for everyday use
A closer look.
Two panel configurations
The 450W option includes 2 × 225W panels; the 900W option includes 4 × 225W panels. These totals describe rated solar-panel capacity, not guaranteed AC output or daily energy production.
Check the space before you install
Each panel measures 1159 × 1009 × 20 mm and weighs 4.3 kg. Use the per-panel dimensions and the installation instructions to plan a suitable mounting layout and cable route.
Build around compatible equipment
These configurations include panels, solar cables, cable ties and a user manual. A microinverter is not included; choose compatible conversion or charge-control equipment for the planned system.
A planned balcony installation
Assess the available sunlight, mounting surface and panel layout before selecting a kit. Have the mounting and electrical design checked for your intended installation.
A modular solar project
Compare panel count, electrical ratings and the receiving equipment requirements to select a suitable configuration. Plan around actual available space and sunlight.
Panel ratings are not complete-system ratings
The electrical figures below apply to one 225W panel. System voltage and current depend on the configuration and connected equipment. Have a qualified installer confirm the mounting method, compatible equipment and electrical connection before use. The panel IP rating does not apply automatically to cables, connectors or other system components.
Contents by selected configuration
450W: two panels, two 2m solar cables, 24 cable ties and one user manual. 900W: four panels, four 2m solar cables, 48 cable ties and one user manual. A microinverter is not included.

Rated panel power is measured under standard test conditions. Actual output varies with sunlight, shade, panel angle, temperature and the connected equipment. Keep electrical connections and connected devices dry.
Before you get started
A few useful answers.
What do the two wattage options mean?
They describe the total rated panel capacity: 2 × 225W for 450W, or 4 × 225W for 900W.
Do the dimensions and electrical values describe the whole kit?
No. The specifications marked “per panel” apply to one module. Use the panel count for your selected option when planning the installation.
Is a microinverter included?
No. These panel configurations do not include a microinverter. Select compatible equipment for the planned system.
Will the system always produce its rated power?
No. Solar output depends on sunlight, shading, orientation and temperature. Actual system output also depends on the connected equipment and installation.
