The answer's provided by Naveen is all great talking points and especially covering safety and installation. Being in the utility industry with Entergy Louisiana, the guidance is to make sure to follow all NEC codes for the installation. Make sure that the solar panels are rated for the size service you plan to provide to the home or business. On Entergy's system it is not allowable to have a battery backup system with solar panels to make sure of no potential of back feed to the lineman during emergency outages.
Complete a verification that the structure that the panels are being mounted on can support the weight of the solar system.
Correct wiring of the panels in the system.
Look over the site to make sure the professionals installing with a have safe entry and exit to the solar panel locations.

You want to make sure they the panels are covered if you are installing during the day. As the sunlight hits the panels they will continue to produce electricity and could be a shock hazard.
Environmental considerations need to be taken as well; you would want to inspect the terrain and direction of the sun to maximize daily exposure. Environmental obstructions could have an impact on the duration of the rising sun versus the setting of the sun. Placement could also make an impact on the effectiveness and longevity of a panel. As efficiency of panels depend on temperature, when applicable - optimal placement can take advantage of natural cooling devices such as winds or periodic shade.

Safety Precautions while handling Solar panels.
• Use proper protective gear –Glasses, Gloves, etc. to reduce the risk of electric shock.
• Do not wear metallic jewelry while working with any electrical circuits.
• Hold solar panels with two hands while transporting. Do not hold by the junction box or wires.
•Keep the solar panel covered until after you’ve mounted and made all electrical connections.
•Be careful not to touch any live positive wire with a live negative wire.
Fundamental steps followed in installation process.
Step 1 –Plan your Installation.
Step 2 –Route the Wire.
Step 3 –Mount & Wire Solar Charge Controller.
Step 5 –Connect the Battery Wires.
