⚙️ Key Factors to Consider When Choosing Solar Panels
Efficiency: The Most Critical Metric
Higher efficiency = more power from less space. Maxeon currently leads this category, offering top-tier cell technology that performs better even in low sunlight. Panel efficiency refers to the percentage of sunlight that hits the panel and gets converted into electricity. While premium panels now exceed 22% efficiency, even mid-range panels typically offer 19-21% efficiency, which may be sufficient for many homeowners with adequate roof space.
It's important to understand that efficiency ratings are measured under Standard Test Conditions (STC) in laboratory environments. Real-world performance can vary based on temperature, shading, orientation, and other factors. The National Renewable Energy Laboratory (NREL) maintains a database of actual field performance for various panel models.
Power Output: Watts Matter
Measured in watts (W). A higher wattage panel — like VSUN's 490W — produces more energy, ideal for smaller rooftops. When comparing panels, look at both the rated power output and the actual expected generation based on your location. The PVWatts Calculator from NREL is an excellent tool for estimating production based on your specific location and system configuration.
Modern residential panels typically range from 350W to 500W, with commercial panels reaching up to 700W. Higher wattage panels can reduce balance-of-system costs (racking, wiring, labor) since you need fewer panels to achieve the same system size.
Warranty: Your Long-Term Protection
Choose at least 25 years of performance warranty. Maxeon's 40-year warranty is unmatched in 2025. Solar panel warranties typically include two components: a product warranty that covers manufacturing defects, and a performance warranty that guarantees a certain level of power output over time.
Most premium panels guarantee 92% of original output in year 1, degrading to about 85-88% by year 25. The degradation rate is a critical factor - premium panels typically degrade at 0.25-0.3% per year, while standard panels degrade at 0.5-0.7% annually.
Cost & Value: Looking Beyond the Price Tag
While Maxeon and REC cost more upfront, they deliver lower long-term cost per watt over time. When evaluating cost, consider the levelized cost of energy (LCOE), which accounts for the total cost of the system divided by the total energy produced over its lifetime. Premium panels often have a lower LCOE despite higher initial costs because they generate more electricity over time.
According to U.S. Department of Energy data, the average cost for residential solar installations has dropped by more than 70% over the past decade, making 2025 an excellent time to invest.
American-Made Preference: Supporting Domestic Manufacturing
If supporting local manufacturing matters, Qcells and First Solar are two strong U.S. options. The domestic solar manufacturing industry has received significant support through legislation like the Inflation Reduction Act, which includes incentives for American-made clean energy products.
American-made panels often have shorter supply chains, which can mean faster delivery and potentially better customer service. They may also qualify for additional incentives in some states or utility programs that prioritize domestic content.
Temperature Coefficient: Performance in Heat
The temperature coefficient indicates how much panel efficiency decreases as temperatures rise. This is particularly important in hot climates like Arizona, Texas, and Florida. Panels with better temperature coefficients (closer to zero) will maintain higher output during hot summer days.
Fire Rating and Building Code Compliance
Ensure your panels meet local building codes and fire safety standards. In the U.S., panels should have UL 1703 certification and appropriate fire ratings (Class A, B, or C) for roof installations.

🏠 Installation Considerations for American Homes
Roof Assessment and Preparation
Before installing solar panels, your roof should be in good condition with at least 10-15 years of remaining life. If your roof needs replacement soon, it's often more cost-effective to replace it before solar installation. The ideal roof for solar faces south with a pitch between 15-40 degrees, though east and west-facing roofs can also work well.
Local Regulations and Permitting
Solar installations require permits from your local building department and must comply with zoning regulations. Many areas also have homeowners association (HOA) rules that may restrict solar installations, though solar access laws in most states limit HOAs' ability to prohibit solar systems.
Financing Options
There are several ways to finance your solar installation:
- Cash Purchase: Highest long-term savings but requires significant upfront investment
- Solar Loans: Monthly payments similar to your current electric bill, with ownership after payoff
- Leases/PPAs: Little or no money down, but you don't own the system and savings are typically lower
- Home Equity Loans: May offer tax benefits and lower interest rates
Finding a Qualified Installer
Choose a installer certified by the North American Board of Certified Energy Practitioners (NABCEP). Get multiple quotes, check references, and verify that the company is properly licensed and insured. The Solar Energy Industries Association (SEIA) maintains a directory of reputable installers.
