Steps

1
Evaluate your home's annual energy usage, the wattage of available panels, and the number of sunny days in your area to determine the system size needed.
2
Inspect the current electrical panel; if it uses fuses, lacks amperage, or has no space for new circuits, plan for an upgrade costing between $1,000 and $4,000.
3
Assess roof orientation and potential shade from trees or buildings, as southern-facing roofs are ideal for capturing maximum sunlight.
4
Research and vet various solar providers to obtain quotes and determine if buying or leasing the equipment is more financially viable.
5
Apply for available financial incentives, such as the federal 30 percent tax credit offered through 2033 or utility company rebates.
6
Hire a qualified solar professional to install the panels and electrical components to ensure the system is operating safely.
7
Contact your utility company to establish a net metering program, which allows you to sell excess energy back to the grid.

Pro Tips

  • Homes with solar energy systems sell for an average of 4.1 percent more.
  • Solar shingles can be a more cost-effective alternative to traditional panels and blend better with the roof.
  • Annual professional cleaning of panels ensures they stay in top working condition.
