1. Efficiency Ratings

   • Look for panels with higher efficiency ratings (15-22%) for maximum energy output in limited space.

2. Types of Solar Panels

   • Familiarize yourself with different types: Monocrystalline, Polycrystalline, and Thin-Film panels. Choose based on your needs and budget.

3. Durability and Warranty

   • Check the warranty period (typically 25 years) and durability of the panels. Look for panels that can withstand extreme weather conditions.

4. Reputation of the Manufacturer

   • Research manufacturers for their track record, customer service, and longevity in the solar industry.

5. Installation Considerations

   • Assess the complexity of installation. Choose an experienced installer for optimal performance and safety.

6. Inverter Type

   • Choose between string inverters, microinverters, or power optimizers, as they affect efficiency and monitoring capabilities.

7. Cost and Financing Options

   • Compare prices from various suppliers and explore financing options like loans, leases, or Power Purchase Agreements (PPAs).

8. Local Incentives and Rebates

   • Investigate local/state incentives to reduce upfront costs. Tax credits and rebates can significantly lower your investment.

9. Space and Orientation

   • Evaluate the available roof space and orientation to maximize sunlight exposure. Ideal angles and orientations can enhance efficiency.

10. Environmental Considerations

    • Look for panels made with sustainable practices and low environmental impact during manufacturing.

11. Performance in Shade

    • Research how the panels perform in shaded conditions, if applicable, and consider panel options that minimize efficiency loss.

12. Maintenance Requirements

    • Understand the maintenance needed to keep the panels operating at peak efficiency and factor these costs into your budget.

Following these tips can help you make an informed decision when choosing solar panels.
