KKT KOLBE High Performance Solar Module SP420-03BI

This bifacial premium PV module with 420 Wp output and a module efficiency of 21.51% offers a better energy yield than modules with lower efficiency even in low light conditions.

The back of the module is made of tempered glass, so both sides of the module can generate electricity. This is particularly advantageous when installed as a photovoltaic fence, carport or terrace roofing or noise barrier, etc.

Thanks to the high performance and efficiency, you save up to 178,- EUR electricity costs per panel per year.

High load capacity and minimal losses due to shading.

The solar module's low temperature coefficient of -0.25% guarantees optimum power output even on hot days.

The excellent anti-PID performance through optimised production processes and strict quality control prevents power losses in humid weather.

Due to the "Hot-Spot-Protect" quality assurance process, all cells of the module are guaranteed hot-spot free.

The PV panel is 172.2 cm long, 113.4 cm wide and 3 cm high. The front and rear panels made of tempered glass with anti-reflective coating and the robust anodised aluminium frame ensure best stability, even in strong winds (up to 2400 Pa) and heavy snow loads (up to 5400 Pa). The module can be securely mounted using standard mounting systems. The mounting system is not included in the scope of delivery.

Modules can be easily connected to each other with the MC4 connector system.

Delivery is by forwarding agent free kerbside (the modules are not carried into the home). The forwarding agent will contact you via e-mail to arrange a delivery date with you.

How do I compare prices of PV modules?

The purchase price of PV modules is calculated in watts.

Example PV module from KKT KOLBE:

Purchase price: 269 €
Power: 425 Wp
Calculation: 269 € / 425 Wp = 0,63 €/Wp Price per Watt: ~0,63 €Wp

Competitor module:

Purchase price: 259 €
Output: 400 Wp
Calculation: 259 € / 400 Wp = 0,64 €/Wp

Pay attention to the module efficiency. This should be at least 21%.

*The annual savings per panel were calculated on the basis of an output of up to 445 kWh per year and an energy price of 40 cents/kWh with optimal module orientation. With higher or rising electricity prices, the savings per photovoltaic module increase.
