We’ll Select the Right Solar Power System For:
- Garage cooperatives or individual garage units
- Private garages next to residential homes
- Workshops, warehouses, and collection points
Why Install a Solar Power System in a Garage
- Have lighting and powered outlets without a generator, even during blackouts
- Work off-grid: soldering iron, ventilation, and compressor operate on solar power
- Charge all portable devices in your garage: battery-powered tools, flashlights, power banks
- Keep your garage secure: electric gates, alarms, and cameras remain operational without interruptions
What a 3 kW Solar Power System Can Power in a Garage
- Lighting: Up to 10 LED fixtures (totaling 100-150 W)
- Wi-Fi and Security: Continuous operation of Wi-Fi, routers, alarm systems, and video cameras
- Tool and Device Charging: Ability to charge cordless drills, saws, soldering tools, flashlights, and power banks
- Small Appliances: Can power a refrigerator (up to 200 W), a fan, an air compressor, and a ventilation system
- Electric Garage Doors or Automation: Short-term operation
- Tools: Drill, angle grinder, and soldering station can be used one at a time
- This provides a clearer overview of the capabilities of a 3 kW solar power system in a garage environment.

FAQ
For systems up to 3 kW in a private garage, a permit is usually not required. However, in a garage cooperative, you may need approval from the management or neighbors for roof usage and cable routing.
A 1.5-3 kW system can power lighting, wall outlets, tool and e-bike chargers, alarm systems, and garage door automation. With a battery energy storage system (BESS), the system can operate fully during power outages.
Yes. During the day, the system operates on solar power, and at night, it switches to the grid. However, backup power during blackouts requires a BESS.
- Solar panels: up to 25 years
- Inverter: up to 10 years
- BESS: 6-10 years, depending on usage cycles
Yes, the system still works, but energy generation will be lower. That’s why we recommend having a BESS and/or using a night tariff for battery charging.
