Frequently Asked Questions
Your roof should have enough sunlight exposure, minimal shade, and be in good condition. Homes in states with net metering incentives or high electricity rates benefit the most from solar. A solar provider can conduct a site evaluation to check feasibility.
The average cost ranges from $10,000 to $30,000 after incentives. The price depends on panel type, energy needs, and local tax credits. Many companies offer financing or leasing options to lower upfront costs.
If your panels don’t meet your energy needs, you can:
- Add more panels if space allows
- Use battery storage for excess power
- Stay connected to the grid to supplement energy usage
To make sure this issue does not occur, ask the provider to properly size the system before installation.
Most panels last 25-30 years with minimal maintenance. Cleaning the panels 1-2 times a year and checking for debris or shading issues keeps them running efficiently. Some companies offer monitoring systems to track performance as well.
Yes! The federal solar tax credit (ITC) allows you to deduct 30% of installation costs from your taxes. Many states also offer rebates, net metering, and solar renewable energy credits (SRECs). We recommend checking local programs before investing.
