The cost of a Solar Energy System for a residence or business depends on the size of the solar array, the type of system, and the design factors affecting the site.
The size of the solar array depends on the available sun in your area and the amount of energy that you need for your home or business. GreenLife Technologies can determine the amount of available sun at your site by evaluating the location, orientation, and shading of the Solar PV array.
The size of the system also depends on your electricity needs. The electricity needs can be determined by evaluating past electricity bills. If you have a new house, GreenLife Technologies can determine your probable needs by analysis and experience from other projects.
Costs for typical Solar Systems depending on type of system:
Grid-tie Systems: $4 to $6 per watt.
Grid-tie with backup Systems: $5 to $8 per watt.
Off-grid Systems: $6 to $10 per watt.
Example: Typical Residence in the Southern United States
A typical house in the southern United States uses approximately 12,000 Kwh/year or about 1,000 Kwh/month. A 5,000 watt PV System would typically offset more than half of the power required by this house. Grid-tie systems cost between $4 and $6 per watt.
This system would cost approximately $5.2 * 5,000 watts = $26,000.
This is installed cost without tax credits or incentives. For this residence, there is a $2.00 per watt incentive from the electricity provider, and a 30% tax credit.
-$10,000 - $2.0 * 5,000 watts
-$4,800 - 30% * $16,000 (tax credit) (this assumes that the incentive payment is taxable
check with your accountant)
$11,200 - Price after incentives and tax credits. This system will pay for itself more than twice in its lifetime.
