  7. Abstract:
  8. Solar panels are still rather expensive equipments. At current electricity prices, it takes several years to return the investment made to install them in a household. Smarter use of their produced energy can help reduce this break-even time, and hence, would motivate more households to be willing to install and use them which would finally result in a more sustainable society with less reliance on fossil fuels. Electricity prices usually differ at different times of day with the common, but unfortunate, property that the price is maximized at evenings when the solar energy production is minimal or non-existent while at the peak production of the solar panels, i.e., around noon, the price is usually much lower. We present the design of controllers that help more economically use the produced and stored solar electrical energy by forecasting future load of a few days ahead, and use that energy at the most economical times when the electricity fee is the highest. We implemented our technique in an educational building and showed that this scheme can improve financial advantage of solar panels by 41% compared to direct connection of solar panels production to the grid, and hence reduce the break-even time by the same amount. In another tariff structure where the price is increases in several steps based on total consumption, we show that our equipment and technique reduce the paid utility fee by over 65%
