Frequently Asked Questions
How many solar panels do I need?
The number of panels depends on your energy consumption, roof space, panel wattage, and sun exposure. Our calculator considers all these factors to provide accurate estimates.
What is solar panel ROI?
Solar ROI measures how long it takes to recover your initial investment through energy savings. Most residential systems pay for themselves in 5-10 years, then provide free electricity for 15+ years.
Can I reduce my carbon footprint with solar?
