A solar installer will conduct a site assessment to accurately determine the optimal system size for your home.
Common Mistakes to Avoid When Going Solar
Navigating the solar landscape can be complex. Avoiding common pitfalls can save you time, money, and frustration.
- Failing to Get Multiple Quotes: Compare quotes from several solar installers to ensure you’re getting a competitive price.
- Ignoring System Performance Guarantees: Ensure the solar installer offers a performance guarantee that covers a certain percentage of energy production over time.
- Neglecting Roof Condition: Address any roof repairs or replacements before installing solar panels.
- Overlooking Local Incentives: Research and take advantage of all available federal, state, and local tax credits and rebates.
- Choosing the Cheapest Option Without Considering Quality: Prioritize quality and reliability over the lowest price.
- Not Understanding Net Metering Policies: Understand how your utility company credits you for excess energy sent back to the grid.
Understanding Net Metering and Solar Incentives
Net metering allows you to receive credits on your electricity bill for any excess solar energy that you send back to the grid. Federal and state tax incentives, along with rebates, can significantly reduce the upfront cost of a solar system, making it more affordable. The federal Investment Tax Credit (ITC) currently provides a significant percentage back on the cost of the system.
Financing Options for Solar
Several financing options are available to help homeowners afford solar panels.
- Cash Purchase: Paying for the system upfront can save you money on interest charges in the long run.
- Solar Loan: Securing a solar loan allows you to finance the system over time, with fixed monthly payments.
- Solar Lease: Leasing solar panels involves paying a fixed monthly fee to use the system, but you don’t own it.
- Power Purchase Agreement (PPA): A PPA allows you to purchase solar energy from a third party at a fixed rate, typically lower than your current utility rate.
