Is It Possible To Use Solar Energy Year-Round In Snow Country?

Choosing the Right Equipment

When selecting solar panels for snow country, consider using panels with a high snow load capacity, typically above 5,000 Pa (0.5 kPa). This ensures that the panels can withstand the weight of snow and ice without damage. Look for panels with a high maximum power point tracking (MPPT) efficiency, which helps to recover lost power during cold and cloudy conditions. A typical snow load capacity for off-grid solar panels is 10,000 Pa (1 kPa).

Mounting and Angle Techniques

To ensure maximum energy production in snowy conditions, install solar panels at a steeper angle, typically between 30° and 45°. This helps to shed snow more easily and reduces the risk of snow accumulation. Use a secure and adjustable mounting system to ensure the panels can be tilted and leveled according to seasonal changes. Consider using a tracking system that can adjust the panel angle to optimize energy production throughout the year.

Maintenance and Cleaning

Regular maintenance is crucial to ensure optimal performance of solar panels in snow country. Clean the panels at least twice a year, ideally after snowmelt in spring and before winter snowfall. Use a soft-bristled brush or a snow brush with a long handle to gently remove snow and debris. Avoid using high-pressure washes or harsh chemicals that can damage the panels or compromise their warranty. Consider installing a snow removal system, such as a roof rake or a snow-melt mat, to reduce the risk of snow accumulation and improve energy production.
