Frequently Asked Questions
How accurate is this solar panel calculator?
The calculator provides estimates based on standard solar panel performance. Actual results may vary due to weather, shading, panel orientation, and local utility policies.
What factors affect solar panel electricity generation?
Key factors include peak sun hours, panel efficiency, system size, orientation, tilt angle, shading, temperature, and seasonal variations.
How long do solar panels typically last?
Most solar panels come with 25-year warranties and can produce electricity for 30+ years with gradual efficiency decline of about 0.5% annually.
Are maintenance costs included in this calculation?
This calculator focuses on electricity savings and payback period. Consider adding 1-2% of system cost annually for maintenance and inverter replacement.
What about net metering and selling excess electricity?
The calculator assumes basic grid-tied system. Net metering policies vary by location and can provide additional savings for excess electricity production.
How do I determine peak sun hours for my location?
Peak sun hours vary by geographic location and season. Check local solar irradiance data or consult with solar installers for accurate regional values.
Should I consider battery storage in this calculation?
This calculator covers grid-tied systems. Battery storage adds costs but provides energy independence during outages and can optimize self-consumption.
What government incentives are available for solar panels?
Incentives vary by location and time. Common options include federal tax credits, state rebates, and local utility programs that can reduce effective installation costs.
