Frequently asked questions

Selection depends on consumption, appliance power, grid availability and backup needs.

Hybrid solar works with panels, the grid and batteries to generate electricity, store energy and provide backup.

Grid-connected solar operates alongside the grid, primarily to generate electricity and reduce grid consumption.

Off-grid solar works independently of the external grid for sites requiring autonomous supply.

Monthly consumption alone is not enough. We consider monthly and daily usage, maximum load, main appliances, daytime and nighttime consumption, required backup duration, available panel area and roof characteristics. This determines appropriate panel, inverter and battery sizing.

Yes. Panels generate electricity year-round. Winter output is usually lower because of shorter days, weather and the lower sun angle. Modern panels still generate in cold and cloudy conditions.

Output depends on panel capacity, orientation, tilt, shading, weather, season and site conditions. Before installation, we can estimate generation and select a suitable configuration.

Space depends on panel quantity and power. A modern panel of approximately 580 W occupies around 2.8–2.9 m². Design also accounts for clearances, access routes, roof characteristics and mounting hardware.

Yes. Panels can be fitted to different roofs, façades and ground-mounted structures. Before installation, we assess roof type and condition, available area, orientation and suitable panel placement.

Time depends on system power, panel quantity, roof type and project complexity. A standard residential installation usually takes several working days. The exact schedule is agreed after the configuration and site assessment.

Contents depend on the project, but usually include panels, a grid or hybrid inverter, battery storage for hybrid systems, mounting hardware, solar cable and connectors, protective devices, surge protection, earthing, electrical accessories, installation, commissioning and configuration.

The DESTAR team handles equipment selection, design, installation, configuration and commissioning. After installation, customers receive operating guidance and further technical support.

Yes. Panels, inverters, batteries, mounting hardware, cables, protection devices and other components can be purchased without a complete installation service.

Yes. Terms depend on the order and purchase method. PrivatBank instalments and other financing options may be available. Confirm current terms with the DESTAR manager before ordering.

Yes. We deliver equipment within Ukraine. For solar system orders, installation and commissioning can also be arranged.

Yes. DESTAR helps determine equipment requirements and an appropriate configuration. For solar systems we select panels, inverter, batteries, mounts and protection. For battery packs we determine voltage, capacity, current, cell configuration, BMS and connectors.

Yes. Alongside standard solutions, DESTAR works to individual technical specifications. We can select equipment or a battery pack for the requirements of a particular site or device.

Tell our manager what the battery will power and provide known specifications. If you do not have a technical brief, send battery photos, markings or the device, controller or motor model. We help determine parameters and propose a configuration.

Yes. We manufacture custom packs for e-bikes, scooters, motorcycles, tricycles, quad bikes, light electric vehicles, electric drives and custom electric transport systems. The configuration is matched to your technical requirements.

The main factors are system voltage, capacity and maximum load current. We also consider available space, enclosure shape, connector type and controller and motor specifications. The battery must support acceleration and heavy loads as well as normal use.

Yes. We can adapt length, width, height, cell arrangement, wiring, connector type and position, and mounting method to the available space. This is useful for electric vehicles, robotics and specialised equipment.

Depending on the requirements, we use modern 21700 Li-ion cells, including EVE and Samsung. Cell models differ in capacity, permitted discharge current and internal resistance, so selection is based on actual loads, not capacity alone.

Yes, with an appropriate cell configuration. Parallel connections increase capacity and available current. The controller, BMS, charger, wiring and motor limitations must also be considered.

Yes. Custom packs can power robotic platforms, autonomous equipment, mobile systems, electric drives and other machinery. Voltage, capacity, current, dimensions and connections can be matched to the device.

The BMS is selected for the battery configuration and application. We consider series groups, permitted current, charge and discharge parameters, balancing, equipment requirements and protection functions. For high-current systems, the BMS and power circuit are sized for actual loads.

Yes. Provide the device model or specifications. We consider system voltage, capacity, operating and peak current, battery compartment dimensions, connectors, cable length, charger type and BMS requirements.

Provide required voltage, desired capacity, maximum load current, equipment type, dimensions, photos or a wiring diagram, and connector type. If exact specifications are unavailable, send the device, controller or motor model; DESTAR can help determine suitable parameters.

Yes. We make individual custom packs and batches for equipment manufacturers, service companies and other customers. Batch orders can use an agreed cell configuration, BMS, connectors, cable lengths and other parameters.
