Frequently Asked Questions
-
How long does a solar panel system last?
Quality solar panels can last 25-30 years or more with proper maintenance. The inverter may need to be replaced after 10-15 years.
-
Can I install solar panels myself?
While some DIY kits are available, professional installation is highly recommended for optimal performance and safety.
-
What happens during a power outage?
Most solar systems are designed to disconnect from the grid during outages for safety. Some systems include battery storage options for backup power.
-
How much space do I need for solar panels?
The required space depends on your system size and roof size. A general rule is 1 square foot of panel per 100 watts of capacity.
-
Is solar energy reliable in cloudy or snowy climates?
Solar panels can still generate electricity in cloudy conditions, although production may be lower. Snow accumulation can temporarily reduce efficiency, but panels are designed to shed snow.
