Residential Solar Panel Installation: Step-by-Step Timeline

Initial Consultation & Energy Assessment (1-2 Weeks)

The first step in your solar journey is a free consultation with our experts. We’ll evaluate your energy needs, roof condition, and sun exposure to design a system that maximizes efficiency.

Key Factors We Consider

  • Current energy usage (based on utility bills)
  • Roof type, angle, and shading (to optimize panel placement)
  • Local weather patterns (for maximum sunlight absorption)

Custom Solar System Design (1-2 Weeks)

Once we assess your property, our engineers create a custom solar design personalized to your home. This includes:

  • Panel placement (roof or ground-mounted)
  • Inverter selection (string vs. microinverters)
  • Battery storage options (if desired)

Permitting & Utility Approvals (2-6 Weeks)

Before installation, we handle all necessary permits from:

  • City or county building departments
  • Local utility companies (for net metering approval)

Permitting times vary by location (Fresno, Clovis, and Madera may have different processing speeds), but our team speed-up the process to avoid delays.

Solar Panel Installation (1-3 Days)

Once permits are secured, our certified solar panel installers begin the physical installation. For a typical 5-10 kW residential system, this takes 1-3 days, depending on:

  • Roof complexity (steep vs. flat roofs)
  • Weather conditions (rain or extreme heat may cause minor delays)

Inspection & Activation (1-2 Weeks)

After installation, a final inspection ensures compliance with local codes. Your utility company will then approve the system for activation, allowing you to start generating solar power.

We recommend commercial solar users to do a MINIMUM of two cleanings a year, but most recommended will be 3 to 4 times a year (based on size & environmental factors that their site deals with).

Birds nesting under your solar panels has became a huge problem with the new age of solar powered homes & building. We solve this by a combination of solar expertise & bird control expertise. We offer all forms of bird control solutions, but the most population solution is what it normally called as Solar Bird Netting or Solar Bird Guard or Wire mesh around solar panels.
How much does bird netting around solar panels cost?
Solar Bird Netting or oftenly called (Solar Wire Mesh, Bird Guard, Bird Netting, Bird Proofing) Cost depends on multiple variables.
