4kW Solar Electric System
Innovative Power Systems installed this 4kW solar electric system in Minneapolis, Minnesota in two phases. The owner installed a 2kW system on the top roof in 2006 and added the second phase in 2009. IPS expects this system to produce about 5,000kWh of electricity on average per year. Producing 5,000kWh of electricity annually from coal emits about 10,000 pounds of carbon dioxide. Preventing this much carbon dioxide from being released to the atmosphere is equivalent to adding 500 trees to our forests. Over a 30-year span, IPS expects this system will offset 300,000 pounds or 150 tons of carbon dioxide.
