Waverly Light and Power harnesses the sun's energy with solar panels.
Energy from the Sun
Waverly Light and Power harnesses solar energy for our customers. During February 2010 we installed a solar array containing photovoltaic cells at our Service Center.
Solar energy complements the green power already in use - hydro and wind. Capitalizing on all of these renewable energy sources helps Waverly Light and Power continue to reduce carbon emissions in the environment.
In recent years, the manufacturing costs of photovoltaic cells have dropped as they became more common. On a cost per unit basis, a solar array is not for the faint at heart, which is why Waverly Light and Power embarked on this venture - to learn more about solar energy production in the Iowa climate. As the costs continue to drop, we want to be a customer resource with first-hand knowledge for Waverly businesses and residents considering utilizing solar energy for some of their electrical needs.
Solar Array Facts
3 arrays: 16 panels each
23,745 lbs CO2 saved a year, which is equivalent to a car using 1,188 gallons of gas
Generates about 12,630 kWhs a year
10 KW system; enough to cover 2 homes running at peak capacity (using air conditioners)
The rooftop array is two 21 feet x 8 feet strips
The two ground arrays are 22 feet x 11 feet each
9 foot deep, 30 inch diameter foundation
Solar Energy Generation
How is Solar Energy Generated?
Solar cells are made of semiconducting material similar to those used in computer chips. When they absorb sunlight, the solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity. This process of converting light (photons) to electricity (voltage) is called the photovoltaic effect.
Does Iowa have enough sun in the winter to produce Solar Energy?
Yes. The panels use light, not heat; so as long as there is light they are generating electricity. The snow also reflects light from the sun, which is why the panels point down to the ground during much of the winter season.
