In recent years there has been an outburst of interest in the use of renewable energy sources to reduce greenhouse gas emissions. These renewable energy sources are generally putting out dc power and hence some intermediate energy conversion to ac is essential for its use. Unfortunately, this much needed conversion yields not only extra cost to the system but also introduces power loss which consequently reduces system's efficiency. This DC House project aims to utilize the dc energy directly from renewable energy sources without the need for dc to ac conversion. Besides enhancing system's efficiency while reducing cost, the DC House's main use will be in locations where utility grid is out of reach or geographically inaccessible; hence, the opportunity to promote the use of renewable energy sources while providing electricity to those people who are less fortunate.
