Frequently Asked Questions
Find answers to common questions about solar energy, installation, costs, and more.
General
What is solar PV and how does it work?
Solar PV (photovoltaic) systems convert sunlight directly into electricity using solar panels. When sunlight hits the solar cells, it creates an electric field that generates direct current (DC) electricity. An inverter then converts this DC power into alternating current (AC) electricity that can be used in your home or business.
How long do solar panels last?
Solar panels typically last 25-30 years or more. Most manufacturers offer 25-year performance warranties, guaranteeing at least 80% efficiency after 25 years. With proper maintenance, panels can continue producing electricity well beyond their warranty period.
Will solar panels work on cloudy days?
Yes, solar panels still generate electricity on cloudy days, though at reduced efficiency (typically 10-25% of their maximum output). Modern solar panels are designed to capture diffuse sunlight and can produce power even in overcast conditions.
How much can I save with solar energy?
Savings vary based on your location, energy usage, system size, and local electricity rates. On average, homeowners save $10,000-$30,000 over 20 years. Commercial installations can save hundreds of thousands of dollars annually.
Installation
How long does installation take?
Residential installations typically take 1-3 days once permits are approved. Commercial projects may take 1-4 weeks depending on size. The entire process from consultation to activation usually takes 2-3 months, including design, permitting, and utility approvals.
Do I need to replace my roof before installing solar?
If your roof is in good condition with 10+ years of life remaining, you can proceed with installation. If your roof needs replacement soon, we recommend doing it before solar installation to avoid the cost of removing and reinstalling panels later.
Will solar panels damage my roof?
No, when properly installed by certified professionals, solar panels actually protect your roof from weather elements. We use specialized mounting systems that seal penetrations and distribute weight evenly, preventing any damage to your roof structure.
What maintenance is required?
Solar systems require minimal maintenance. We recommend annual inspections and occasional cleaning (2-4 times per year depending on location). Most systems include monitoring to alert you of any performance issues. Our maintenance plans cover all necessary servicing.
Financial
What financing options are available?
We offer multiple financing options including cash purchase, solar loans, leases, and power purchase agreements (PPAs). We also help you access federal tax credits (30% ITC), state incentives, and local rebates to maximize your savings.
What is the payback period for solar?
The typical payback period is 5-7 years for residential systems and 3-5 years for commercial installations. After payback, you enjoy free electricity for the remaining 20+ years of the system’s life, resulting in significant long-term savings.
Are there tax incentives for solar?
Yes! The federal Investment Tax Credit (ITC) provides a 30% tax credit for solar installations. Many states offer additional incentives, rebates, and performance-based incentives. We help you navigate all available incentives to maximize your return.
Does solar increase property value?
Studies show that solar installations increase property values by an average of 4-6%. Homes with solar sell faster and for higher prices. The exact increase depends on your location, system size, and local real estate market conditions.
Technical
What happens during a power outage?
Grid-tied systems automatically shut down during outages for safety. However, if you have a battery backup system, you can continue using stored energy during outages. Hybrid systems provide the best of both worlds with grid connection and backup power.
Can I go completely off-grid?
Yes, with an off-grid system that includes sufficient battery storage. However, this requires careful sizing to meet your energy needs year-round and is typically more expensive. Most customers prefer grid-tied or hybrid systems for reliability and cost-effectiveness.
How do I monitor my system performance?
All our systems include smart monitoring via mobile apps and web portals. You can track real-time production, energy consumption, savings, and environmental impact. The system sends alerts if any issues are detected, ensuring optimal performance.
What size system do I need?
System size depends on your energy consumption, roof space, budget, and goals. We analyze your utility bills, conduct a site assessment, and design a custom system to meet your specific needs. Residential systems typically range from 3-10 kW, while commercial systems can be much larger.
