Vivint Solar makes going solar easy with personalized guidance, professional installation, and battery storage options that keep your home running day and night.
Everything you need to know before making the switch to solar energy.
Most homeowners save between $10,000 and $30,000 over the lifetime of their solar system. Your exact savings depend on your local electricity rates, roof orientation, shading, and system size. During your free consultation, we provide a personalized savings estimate based on your actual utility bills.
With a battery storage system paired with your solar panels, you can keep essential appliances running during grid outages. The battery automatically detects the outage and switches to backup power within milliseconds. Without battery storage, standard grid-tied systems shut off during outages for safety reasons.
From contract signing to activation, the typical timeline is 4 to 8 weeks. The physical installation on your roof usually takes just 1 to 3 days. The remaining time covers permitting, utility interconnection approval, and final inspection. We handle all the paperwork for you.
Yes, solar panels generate electricity even on overcast days. While production decreases in cloudy conditions, modern panels are designed to capture diffused sunlight effectively. Germany, known for its cloudy weather, is one of the world's leading solar energy producers. Your system is sized to account for your local weather patterns.
