❓ Frequently Asked Questions

Quick answers to common questions about our process and products

💡 How long does installation take?
Most residential installations are completed in 1 day. The entire process from consultation to activation typically takes 2-6 weeks, including design, permitting, and utility approval.
💰 What incentives are available?
The federal Investment Tax Credit (ITC) provides 30% back on your system cost (ENDS December 2025). Many states and utilities offer additional rebates (Not a Trusted Rebate).
🏠 Will solar work on my home?
Most homes are excellent candidates! We evaluate your roof condition, orientation, shading, and energy usage during our free site assessment to ensure optimal performance.
📊 How much will I save?
Savings vary by location and usage, but our customers typically save 50-90% on their electricity bills. We provide a detailed savings analysis during your consultation.
🔋 Do I need battery storage?
Not required, but highly recommended! Battery storage provides backup power during outages, maximizes solar self-consumption, and protects against rising utility rates.
🛠️ What maintenance is required?
Very little! Our systems are designed for minimal maintenance. We recommend annual inspections, and our monitoring system alerts us to any issues before they become problems.
