Background Information
The concept of combining container houses with solar power stems from two separate innovations in sustainable living. Shipping container homes gained popularity in the early 2000s as an affordable and eco-friendly housing alternative. Solar panels, first invented in 1954 by Bell Labs, have become increasingly efficient and affordable over the decades.
Key concepts and terminology:
- Photovoltaic (PV) Cells: The components within solar panels that convert sunlight into electricity.
- Inverter: A device that converts DC power from solar panels into AC power for home use.
- Charge Controller: Regulates the power flow from solar panels to batteries in off-grid systems.
- On-Grid System: A solar setup connected to the main power grid.
- Off-Grid System: A self-contained solar power system not connected to the main grid.
- Battery Bank: A collection of batteries used to store excess solar energy for later use.
Container houses provide an ideal platform for solar panel installation due to their flat, sturdy roofs. The combination of these two technologies creates a synergy of sustainability, offering energy independence and reduced environmental impact.
Planning and Assessment
Evaluating Your Energy Needs
Before installing solar panels, determine your energy requirements:
- Review past electricity bills to understand your average consumption.
- List all appliances and their wattage to calculate total energy needs.
- Consider future energy needs if planning to add more appliances.
Assessing Your Container Roof
Evaluate your container roof for solar panel suitability:
- Measure the available roof space.
- Check the roof’s structural integrity.
- Determine the optimal panel orientation (typically south-facing in the Northern Hemisphere).
- Identify any potential shading issues from nearby structures or trees.
Choosing the Right Solar Panels
Select solar panels based on:
- Efficiency ratings
- Size and weight
- Durability and weather resistance
- Cost and warranty
- Compatibility with your energy needs and available space
Preparing the Container Roof
Cleaning and Inspection
- Remove any debris from the roof surface.
- Inspect for rust, dents, or weak spots.
- Address any structural issues before proceeding.
Reinforcement (If Necessary)
- Consult a structural engineer to assess if reinforcement is needed.
- Add support beams or additional bracing if required.
- Ensure the roof can support the weight of the solar panels and mounting hardware.
Waterproofing
- Apply a waterproof sealant to the entire roof surface.
- Pay special attention to seams and joints.
- Allow the sealant to cure completely before proceeding.
Installing Mounting Hardware
Choosing the Right Mounting System
- Select a mounting system designed for flat roofs.
- Consider adjustable mounts for optimal panel tilt.
- Ensure the mounting system is compatible with your container roof and chosen solar panels.
Marking and Drilling
- Use a chalk line to mark the locations for mounting brackets.
- Ensure proper spacing and alignment for your chosen panel arrangement.
- Drill pilot holes at marked locations, using appropriate drill bits for metal.
Securing Mounts
- Apply weatherproof sealant to each pilot hole.
- Secure mounting brackets using stainless steel bolts and nuts.
- Ensure all mounts are level and firmly attached.
Placing and Securing Solar Panels
Panel Arrangement
- Plan the layout of your solar panels for maximum efficiency.
- Consider factors such as shading and ease of maintenance.
- Leave adequate space between panels for airflow and access.
Attaching Panels to Mounts
- Carefully lift each panel into position.
- Secure panels to the mounting brackets using the provided hardware.
- Ensure all panels are level and properly aligned.
Wiring Panels Together
- Connect panels in series or parallel, depending on your system design.
- Use MC4 connectors for secure and weatherproof connections.
- Secure all wiring to prevent movement or damage from wind.
Installing Electrical Components
Inverter Installation
- Choose a cool, dry location for the inverter, preferably inside the container.
- Mount the inverter securely to the wall.
- Ensure proper ventilation around the inverter.
Battery Bank Setup (for Off-Grid Systems)
- Select a well-ventilated area for battery placement.
- Install battery racks or secure batteries to prevent movement.
- Connect batteries in series or parallel as required by your system design.
Charge Controller Installation
- Mount the charge controller near the battery bank.
- Ensure easy access for monitoring and maintenance.
- Connect the charge controller to the battery bank following manufacturer instructions.
Connecting the System
Wiring to Inverter
- Run DC cables from the solar panels to the inverter.
- Use properly sized cables to minimize power loss.
- Install a DC disconnect switch between the panels and inverter for safety.
Connecting to Battery Bank (if applicable)
- Connect the inverter to the battery bank using appropriate cables.
- Install a battery disconnect switch for safety and maintenance.
- Ensure all connections are secure and properly insulated.
Grid Connection (for On-Grid Systems)
- Hire a licensed electrician for this step to ensure compliance with local regulations.
- Install a new circuit breaker in your main electrical panel for the solar system.
- Connect the inverter output to the new circuit breaker.
Testing and Commissioning
- Perform a visual inspection of all components and connections.
- Turn on the system gradually, starting with the DC disconnect.
- Monitor inverter display for proper functioning and power output.
- Conduct performance tests to ensure the system meets expected output.

Maintenance and Troubleshooting
- Clean solar panels regularly to maintain efficiency.
- Inspect wiring and connections annually for signs of wear or damage.
- Monitor system performance through inverter displays or monitoring apps.
- Address any issues promptly to prevent system downtime.
