Quality and Efficiency
Look for panels with efficiency ratings of 18% or higher. Higher efficiency means better space utilization and long-term savings.
Warranty Terms
Most quality manufacturers offer 25-30 year product warranties. Check the terms carefully, especially degradation guarantees.
Local Support
Choose companies with service centers in your area. Installation, maintenance, and troubleshooting become easier with local support.
Track Record
Research installation data and customer reviews. Companies with thousands of happy customers show their reliability.
Price and Value
Don’t just look at upfront costs. Calculate the cost per watt and consider the total cost of ownership including installation and maintenance.
