Frequently Asked Questions
How accurate is this solar panel calculator?
Our calculator uses industry-standard formulas and average values to provide estimates. Results may vary based on actual conditions, local regulations, and installation specifics. We recommend consulting with local solar installers for precise quotes.
What factors affect solar panel savings?
Key factors include roof orientation, shading, local weather patterns, electricity rates, system size, panel efficiency, installation costs, and available incentives. Our calculator considers most of these variables.
How is the payback period calculated?
The payback period is calculated by dividing the net system cost (after tax credits) by the annual savings. This shows how many years it takes for the system to pay for itself through electricity savings.
What is included in the system cost?
The system cost includes solar panels, inverters, mounting hardware, installation labor, permits, and other necessary components. Financing costs and extended warranties may add to the total cost.
Are there other incentives besides federal tax credits?
Yes, many states, utilities, and local governments offer additional rebates, tax credits, or net metering programs. Check with your local authorities and utility company for available incentives in your area.
How long do solar panels last?
Most solar panels come with 20-25 year warranties and can continue producing electricity for 30+ years. Performance typically degrades by about 0.5-0.8% per year, which is factored into long-term savings calculations.
