If you live in Minnesota, Michigan, or Maine, you’ve probably wondered: “Are solar panels worth it in snowy climates?” The short answer: Yes! Modern solar panels are designed to thrive in cold, snowy regions—and even generate power as snow melts.
But not all panels are built for harsh winters. From snow buildup to sub-zero efficiency losses, choosing the right system matters. In this guide, we’ll break down:
- The 5 best solar panels for snowy climates (tested in -20°F).
- Key features to prioritize: snow load capacity, temperature coefficient, and durability.
- Pro tips to prevent snow accumulation and maximize winter ROI.
Let’s dive in!
Key Features to Look for in Snow-Proof Solar Panels
Not sure what makes a solar panel “snow-ready”? Focus on these three factors:
Snow Load Rating
Panels should handle 40-60 lbs/sq ft of snow (common in northern states).
- Top pick: SunPower Maxeon panels (rated for 113 lbs/sq ft). View SunPower Maxeon 6 Specs
Temperature Coefficient
Lower = better. Aim for -0.30%/°C or less to minimize efficiency loss in cold.
- Example: LG NeON 2 panels (-0.30%/°C).
Frame Durability
Look for anodized aluminum frames to resist corrosion from snowmelt and salt.
👉 Pro Tip: Pair panels with a ground-mounted system if heavy snow is common in your area. [Learn how to choose between roof vs. ground solar here.] (internal link)

How to Prevent Snow Buildup on Solar Panels
Even the best panels need smart maintenance. Try these tips:
Adjust the Panel Angle
Tilt panels at 30-45 degrees to help snow slide off naturally. [How to Calculate Solar ROI in Snowy States](internal link)
Install Heating Cables
Brands like EasyHeat offer solar-safe cables to melt ice.
Use a Soft Snow Rake
✅ Pro Tip: Never use metal tools—they scratch panels!
Trim Nearby Trees
Reduce shading to speed up snowmelt.

FAQs About Solar Panels in Snowy Climates
Do solar panels work in freezing temperatures?
Yes! Solar panels perform better in cold weather than extreme heat.
Can snow damage solar panels?
High-quality panels (like our top picks) are tested to withstand heavy snow. Avoid cheap, thin-film options.
How much sunlight do solar panels need in winter?
Even 2-4 hours of sunlight can generate power. Pair panels with a battery (like the Tesla Powerwall) for 24/7 energy. [Top 5 Solar Batteries for Winter Power Outages](internal link)
Final Checklist for Buying Snow-Ready Solar Panels
Before you commit, ask:
☑️ Is the snow load rating over 50 lbs/sq ft? ☑️ Does it have a low temperature coefficient (-0.30%/°C or less)? ☑️ Is the warranty at least 25 years?
