Choosing the Best Solar Panels
Not all panels are created equal. From sleek all-black monocrystalline to budget-friendly polycrystalline, find the perfect match for your roof and budget.
The 3 Main Panel Technologies
The trade-off between efficiency, aesthetics, and price point.
Monocrystalline
Made from single-crystal silicon. They offer the highest efficiency and a sleek black aesthetic that blends into modern roofs.
- Highest Efficiency (20%+)
- Space Efficient
- Sleek Black Look
Polycrystalline
Made from melted silicon fragments. Instantly recognizable by their blue hue. Lower efficiency but significantly cheaper.
- Lowest Cost Per Watt
- Blue "Marble" Look
- Requires More Roof Space
Thin-Film
Lightweight and flexible. While generally less efficient, they perform better in high heat and partial shade conditions.
- Best Heat Tolerance
- Flexible Installation
- Lower Efficiency (15-17%)

Frequently Asked Questions
Expert answers on durability, weather, and maintenance.
Do solar panels work on cloudy days?
Yes, but efficiency drops. Solar panels use visible light, not heat, to generate electricity. On a heavily overcast day, production might drop to 10-25% of peak capacity. However, the "edge of cloud" effect can sometimes cause temporary spikes in production.
Can panels withstand hail?
Most Tier-1 solar panels are tested to withstand golf-ball-sized hail (1 inch diameter) traveling at 50 mph. They are built with tempered glass designed for impact. While extreme storms can cause damage, standard panels are incredibly durable.
What is panel "Degradation Rate"?
All electronics degrade over time. Solar panels typically lose about 0.5% efficiency per year. This means after 25 years, your panels should still be producing about 85-90% of their original power output.
