1. PV Solar System

Azimuth Angle

Position of Sun and Modules how many degree the sun or array from north

Irradiance

How intense the sunlight at Specific Time

Irradiation

Qty of power received for a given amount of time (A day is a typical time frame)

Tilt

The Angle (degree) Solar PV are of the Horizontal surface

Solar window

• Refers to the position of the sky were sunlight available on earth.
• Solar window based on latitude.

Survey for the site

• You have to survey the area were were the array will be located, Make sure nothing will block the path of sun
• You must predict and limit the shade with the best possible

Main Components of PV System

1. PV Module
2. Battery
• The Amount of Energy client need to store
• No of days the client need to go without recharging Battery
• The Amount of solar power available to charge the battery
• Temp @ which the battery stored/worked
3. Charge Controller
4. Inverter
• Grid Direct Inverter
• Battery Based Inverter (In battery based inverter you need to install ground fault protection.)
5. Conductor
• Conductor should be selected to expose high temperature.
• In AC voltage drop based on impedance and DC based on resistance.
6. Protection Devices

Permit and Other Details

• Installation Permit from Building Dept.
• Electricity Permit from Utility provider
• Should be match the Local codes and NEC codes.

Anti-Islanding Features
A Safety feature in grid tied inverter were the inverter recognize power outage in the Grid and Isolates the connection between grid and circuit

Battery
Sealed maintenance free batteries also release hydrogen when charging battery.
