The SunEnergyXT BK215 is a compact and powerful solar module system used for decentralized power generation on balconies, roofs, or commercial installations. It offers easy installation and high energy efficiency – ideal for users who want to reduce their electricity costs and optimize their self-consumption.

The BK215 was specifically designed to meet a wide range of energy profiles. It combines high-performance monocrystalline modules, an intelligent MPPT inverter, and the option for storage integration, making it suitable for both small and larger roof areas.

How can the SunEnergyXT BK215 be configured?

The SunEnergyXT BK215 offers a variety of configuration options that allow users to adapt the system to their individual requirements. From module type and orientation to inverter power and storage compatibility – all parameters can be flexibly adjusted with the BK215.

Typical Configuration Parameters:

Component Option Description
Number of modules 2–8 Adaptable to available area and energy demand
Inverter 300–800 W For different grid connections
Storage 0–5 kWh Optionally with DRBO Greenenergy SunLit system
Mounting angle 15°–45° Optimized for roof or balcony mounting

This flexibility guarantees optimal yield performance in various environments.

What power levels and components are available?

The system can be modularly expanded so that users can precisely adapt it to their energy needs. The BK215 uses high-quality monocrystalline PV modules with a power of approximately 215 Wp per unit.

Key Components:

  • High-performance module SunEnergyXT BK215

  • MPPT inverter (standard or hybrid)

  • DC cable and mounting kit

  • Optional: DRBO Greenenergy storage solution with 1–5 kWh

These modular options allow for gradual scaling of the system without the need for a complete reinvestment.

Why is the SunEnergyXT BK215 particularly efficient?

The efficiency of the BK215 is based on advanced cell technology and integrated power management. Thanks to half-cell technology, power losses are minimized, leading to an efficiency of up to 21.8%.

In addition, the intelligent MPPT inverter ensures stable operation, even with partial shading – an important advantage for use on balconies and flat roofs. The integration of DRBO Greenenergy SunLit storage units maximizes the self-consumption rate.

What storage options are compatible?

The SunEnergyXT BK215 is compatible with various energy storage systems, including DRBO Greenenergy's SunLit Energy Storage systems. These offer capacities from 1.5 to 5 kWh and are plug-and-play compatible.

Depending on requirements, storage can be retrofitted or expanded to increase self-consumption and independence from the electricity grid.

Can the SunEnergyXT BK215 be used as a balcony power plant?

Yes, the BK215 is ideally suited as a balcony power plant. With a suitable micro-inverter and secure plug connections, it can be mounted on almost any balcony or railing. DRBO Greenenergy offers ready-to-mount complete sets including adapter cables and brackets for this purpose.

These plug-and-play systems do not require professional electrical installation and can be connected directly via a Schuko plug.

What installation variants are there?

The BK215 can be installed on flat, pitched, or balcony roofs. Users can choose between fixed frame constructions or adjustable tilt angles to achieve the optimal solar radiation angle.

For example, a tilt angle of 30° to 35° is often recommended for south-facing roofs, while 15° to 25° is usually suitable for balcony systems.

How does the SunEnergyXT BK215 compare to similar systems?

The following comparison shows typical differences between the BK215 and other common PV systems:

Feature SunEnergyXT BK215 Comparison Model A Comparison Model B
Module power 215 Wp 200 Wp 230 Wp
Efficiency 21.8% 20.2% 21.0%
Storage compatibility DRBO SunLit limited full
Warranty 12 years product 10 years 10 years

The BK215 impresses with high efficiency, comprehensive storage compatibility, and a long warranty period.
