Effective Strategies to Block Solar Sales Calls in the U.S.

Unwanted solar sales calls are a common nuisance in the United States, often employing aggressive tactics to secure business. These calls may claim you've won a free solar system or pose as utility companies to gain your trust. To protect yourself from these intrusions, consider implementing the following strategies:

How Can I Block Solar Sales Calls on My Smartphone?

Utilize Built-in Call Blocking Features

Modern smartphones come equipped with features to help manage unwanted calls:

  • iPhone: Navigate to Settings > Phone > Silence Unknown Callers to automatically silence calls from unknown numbers.

  • Android: Open the Phone app, tap the three-dot menu, select Settings > Blocked Numbers, and enable "Block Unknown Callers."

Install Third-Party Call Blocking Apps

Several apps are designed to identify and block spam calls:

  • Verizon's Call Filter: Provides spam detection and blocking.

How Can I Register to Reduce Unwanted Calls?

National Do Not Call Registry

Registering your number with the National Do Not Call Registry can reduce telemarketing calls:

  1. Visit donotcall.gov.

  2. Click "Register Your Phone."

  3. Enter your phone number and email address.

  4. Confirm your registration via email.

Note: While this can reduce calls from legitimate telemarketers, it may not stop all unwanted calls.

What Are Some Additional Tips to Prevent Solar Sales Calls?

Be Cautious with Your Information

Avoid sharing your phone number on public platforms or with untrusted sources.

Use a Secondary Number

Consider using a secondary number for online forms or subscriptions to keep your primary number private.

Report Unwanted Calls

If you receive a spam call, report it to the Federal Trade Commission (FTC) at reportfraud.ftc.gov.

By implementing these strategies, you can significantly reduce the number of unwanted solar sales calls and protect your privacy.
