Abstract
Renewable energy is becoming an essential element when it comes to climate change greenhouse issues. To aid in reducing the CO2 emission into the environment, numerous governments support individual investments in solar system on their residential rooftop. A set of regulations were established by the local utilities to control and manage the input energy power into the grid from the rooftop-installed solar system. One of the main regulation is the maximum allowable size of the single-phase solar inverter. The solar inverter size has direct impact on the maximum PV panels installed on the house rooftop, which control the house maximum electrical output power. In addition, the solar panels are solidly fixed on the house roof, which doesn’t allow to track the sun energy during the day. This also reduces the house output power during a nominal period throughout the day. The study in this paper introduces the maximum power point box that allow the house owner to maximize the output energy during the morning, midday and afternoon period without the need to upgrade the inverter or the single phase system for the house. Also the proposal allows for more efficient building integration between solar panels and building design, which reduces the cost of the proposed system. Case study is also included.
