The Sun has the potential to provide 89,300 tera Watts of power to our planet. Our ability to convert even a fraction of this energy for human use makes a significant impact on current energy generation and consumption trends. World- wide we now add more renewable energy capacity every year than (combined) fossil fuel energy capacity. Solar panels provide a reliable, renewable, non-polluting energy source by converting the Sun’s energy to electricity. The biggest challenge faced in this effort to ‘mainstream’ solar energy is system cost. The system presented in this paper addresses this by integrating readily available, low-to-moderately priced components into the inverter design. In order to reduce cost the system utilizes a motor control unit, in a novel way, as a switching device. Reliability of these systems is also an issue in the field and the system described in this paper addresses this issue by ensuring the use of components that have proven track records in industry and digital control allows for robustness, flexibility and scalability of the design. The cost-effective inverter system presented in this paper has the potential to help accelerate the growth of residential solar energy usage in developing nations as well as in developed countries.
