Residential Solar Electric Power Generation
Introduction
A NW Wind & Solar residential solar electricity generating system provides you with your own supplemental electrical power source to work in concert with power from your electric utility provider. Power is produced when there is sufficient sunlight falling onto your solar panel cells which is then converted to alternating current (AC) and routed throughout your home. Because NW Wind & Solar installations are connected to the existing electricity grid, power is always available.
Solar power systems are installed with both a production meter, which monitors the total amount of electricity produced by your solar array, and a net meter, which both enables you to seamlessly reduce your demand from the electric utility and sell excess supply back when your system generates more than you are using.
Sample residential system
Assumed pre-solar use
♦ 17,166 kWh of electricity purchased from the utility per year
♦ Utility purchases cost approx $1,716.60/year
System size and cost
♦ 4.0 kW solar electric system
♦ System cost after incentives: $18,396
Energy and cost savings
♦ 23% of annual electricity usage — about 3,883 kWh a year — will be generated by the solar electric system
♦ Over its 25-year lifespan, the solar electric system will have generated 97,087 kWh and saved $7,314 over the purchase price — a 39% ROI!
Environmental impact
♦ Use of this solar electric system would result in a reduction of carbon emissions of 65 tons.
♦ This is equivalent to:
§ Planting 2,576 trees
§ Not flying 132,784 air miles
§ Not driving an SUV 82,040 miles
Site considerations
- The inverter is typically located as close as practical to the modules. In a residential application, the inverter is often mounted to the exterior sidewall of the home near electrical main or sub panels.
NW Wind & Solar will ensure your solar installation meets legal requirements and building code regulations and that it is correctly designed to maximize production for your site and conditions.
Is a residential solar electric power system right for you?
Trust an energy architect.
The best way to tell is through a free, no obligation preliminary site evaluation and proposal. A NW Wind & Solar expert will come to your home, survey the site, answer your questions, and prepare a proposal for the installation of a solar power system. Then the choice is up to you.
