Small Solar Electric Systems

A small solar electric or photovoltaic (PV) system can be a reliable and pollution-free producer of electricity for your home or office. Small PV systems also provide a cost-effective power supply in locations where it is expensive or impossible to send electricity through conventional power lines.

Because PV technologies use both direct and scattered sunlight to create electricity, the solar resource across the United States is ample for home solar electric systems. However, the amount of power generated by a solar system at a particular site depends on how much of the sun's energy reaches it. Thus, PV systems, like all solar technologies, function most efficiently in the southwestern United States, which receives the greatest amount of solar energy.

Because of their modularity, PV systems can be designed to meet any electrical requirement, no matter how large or how small. You can connect them to an electric distribution system (grid-connected), or they can stand alone (off-grid). You can also use PV technology to provide outdoor lighting.

FACT SHEET: President Obama Announces Commitments and Executive Actions to Advance Solar Deployment and Energy Efficiency

Private and Public Sector Commitments and Executive Actions Will Create Jobs and Cut Carbon Pollution

Today, President Obama announced more than 300 private and public sector commitments to create jobs and cut carbon pollution by advancing solar deployment and energy efficiency. The commitments represent more than 850 megawatts of solar deployed – enough to power nearly 130,000 homes – as well as energy efficiency investments that will lower bills for more than 1 billion square feet of buildings.  Additionally, the President announced new executive actions that will lead to $2 billion in energy efficiency investments in Federal buildings; smarter appliances that will cut carbon pollution by more than 380 million metric tons – equivalent to taking 80 million cars off the road for one year – and will save businesses nearly $26 billion on their energy bills; and training programs at community colleges across the country that will assist 50,000 workers to enter the solar industry by 2020. 

President Obama is committed to making 2014 a year of action and has pledged to use the power of his phone and his pen to expand opportunity for all Americans. Last month, the White House hosted a Solar Summit celebrating cross-sector leadership on solar and calling for commitments to support solar deployment and jobs through the expand use of solar in our homes, businesses, and schools.   The President has also called on private and public sector leaders to join the Better Buildings Challenge and continue improving the efficiency of American commercial, institutional, and multifamily buildings and industrial plants by 20 percent or more over ten years.

Today, leaders from the private and public sectors are answering the call. Altogether, more than 300 multifamily housing, homebuilder and home improvement, rural electric cooperative, commercial sector (including retailers, food service, and hospitality), and public sector (including states, cities, school districts) organizations are announcing commitments.
