To troubleshoot these problems, it is important to:

• Visually inspect the system
• Use a multimeter to test for electrical faults
• Tighten loose connections
• Repair or replace damaged panels
• Contact a roofing contractor to fix roof leaks

5. What is the difference between AC and DC solar systems?

AC solar systems use alternating current (AC), while DC solar systems use direct current (DC). AC systems are more common in residential applications, while DC systems are more common in commercial applications. The main difference between AC and DC systems is the way in which the electricity is converted from sunlight. In an AC system, the electricity is converted from DC to AC using an inverter. In a DC system, the electricity is not converted to AC, and it is used directly by the appliances in the home or business.

The benefits of installing a solar system for a homeowner include:

• Reduced electricity bills
• Increased property value
• Environmental benefits
• Energy independence

7. What are the different types of solar mounting systems available, and what are their advantages and disadvantages?

Roof-mounted systems

• Advantages: Easy to install, can be used on most roofs
• Disadvantages: Can be unsightly, can be damaged by wind or hail

Ground-mounted systems

• Advantages: More durable than roof-mounted systems, can be installed on any type of land
• Disadvantages: More expensive to install, can take up a lot of space

8. What is the best way to size a solar system for a home?

The best way to size a solar system for a home is to:

• Calculate the average daily electricity consumption of the home
• Determine the amount of sunlight that the home receives
• Choose a solar panel system that will generate enough electricity to meet the home’s needs

9. What are the different types of solar incentives available, and how do you qualify for them?
