Frequently Asked Questions
Can I get free solar panels in Las Vegas?
No legitimate “free” solar programs exist in Las Vegas. Companies advertising “free solar” typically offer leases or PPAs where you don’t own the system. While these options require no upfront payment, you’ll make monthly payments and miss out on tax credits and full savings benefits. Cash purchases or solar loans provide the best long-term value.
How much can solar panels save on my electric bill?
Las Vegas homeowners typically save 85-95% on their electricity bills with properly sized solar systems. Average monthly savings range from $150-$400 depending on system size and energy usage. However, you’ll still pay a monthly connection fee ($10-$25) to NV Energy even with solar.
What size system do I need for my home?
System size depends on your annual electricity usage. Most Las Vegas homes need 6-8 kW systems due to high air conditioning usage. A professional assessment considers your past 12 months of usage, seasonal patterns, and future needs like electric vehicle charging. As a rough guide, divide your annual kWh usage by 1,400 to estimate system size needed.
How do solar panels perform in Las Vegas heat?
Solar panels actually lose efficiency in extreme heat, dropping about 0.4% per degree above 77°F. However, Las Vegas’s intense sunlight more than compensates for heat losses. High-quality panels with better temperature coefficients perform best in desert conditions. Proper installation with adequate airflow beneath panels helps minimize heat impact.
