Solar generates electricity for the sun “radiation”.  As the sun gets closer to earth we have longer sun hours which create more electricity.  As the sun moves away from the earth we have shorter sun hours or less electricity.

 

Solar for a residence is designed to match and exceed the properties electricity usage.  The purpose is to generate extra electricity in the summer month to compensate for low sun hours in the fall and winter months.

 Electricity Basic:   Electricity is rated in kilo – meaning 1000 – watts. 

                                   Property uses kilowatts (kW) of electricity every hour.

                                   This is stated as kWh on the utility bill - Check your Bill

1. Determine Electricity Usage

1. How much electricity your home uses in kWh per each month? 
2. Calculate 1-years of usage.

4. Solar Incentives & Financing

2.  Determine Sun Exposure

1. Is the property in full sun or shade or shady location?
2. How many trees and location of trees to home?
3. Property direction; south, north,east and west

3. Determine Budgeting – Cost of Solar

Cost is priced based on the watts of electricity in the solar system, considering the solar panels and inverting equipment. 

Example: 

small usage 10,500 kWh a Year, 5000 W solar system

cost estimate; 5000 W x $ 3.05* a watt = $15,250.00

Subtract Incentives:  $3,000 or higher

Subtract 30% IRS deduction

Total Price: 15,250.00 - $3,000 - 3,675 = $8,575

Note: Solar price per watt in Texas is $3.00 to $3.48 

This is a cost analysis estimate only.   Your home usage will determine the solar system sizing.
