Assessing Your Off-Grid Home’s Lighting Needs in Alaska

The first step when determining the best off-grid lighting setup is to assess your household’s specific lighting requirements and the ways different spaces will be utilized. Important factors to take into account include:

Calculate Total Number of Rooms Requiring Light
Make a comprehensive list of all rooms and spaces that will need lighting on a daily basis. This should include essential rooms like kitchens, bathrooms, living rooms, and bedrooms. But also factor in spaces like hallways, closets, basements, porches, and exterior outbuildings if they will be used routinely. Rigorously accounting for all areas that require light will give you an accurate overall picture of your lighting needs.

Consider Lighting Purpose Room-by-Room
Evaluate each room’s primary lighting purpose and lighting needs. Bright, focused task lighting is ideal for kitchen countertops where food prep will occur or work table areas. Ambient lighting may work better for bedrooms, hallways, and infrequently used storage closets. Think through how each room will be utilized and the lighting tone that would be most practical and comfortable.

Make a Room-by-Room Lighting Wattage Calculation
Add up the total wattage of lighting planned for each room based on its purpose. Average wattage guidelines per room:

  • Kitchen: 300-400 watts to provide bright work area task lighting
  • Living Spaces: 200-300 watts for reading or relaxed living
  • Bedrooms: 100-200 watts for low lighting to move around safely
  • Bathrooms: 50-100 watts for grooming tasks
  • Utility Spaces: 50-100 watts for intermittent use

Tabulating the wattage by room provides a baseline for what your renewable energy system may need to produce to power your lighting needs.

Account for Alaska’s Seasonal Daylight Variations
When determining your lighting requirements, it’s crucial to factor in Alaska’s seasonal variations in daylight hours. During the peak summer months, you may have 20+ hours of ample natural daylight even in far northern regions. This can dramatically decrease the need for electrically powered indoor lighting during late spring, summer, and early fall.

But the long nights of winter are a different story. Areas like Barrow only average 4 hours of daylight at the winter solstice. Even Anchorage averages less than 6 hours of daylight in December. The further north your off-grid home is located, the more extreme the seasonal daylight variation. In the winter, your renewable energy system will need to account for powering lights for potentially 20+ hours per day – a significant increase from summer’s extended daylight availability.

So the takeaway when estimating your lighting needs is to calculate based on powering all essential lights for Alaska’s longest nights during winter months. This ensures your system can keep your home adequately illuminated year-round. Supplement plentiful summer sun with backups like battery storage to accommodate the challenges of winter’s minimal daylight.
