Simply put, photovoltaic solar panels convert sunlight into electricity. To do this, several steps are required, as you can imagine. These are the most expensive parts of the system and typically account for 60% of the cost of your system.
Solar panelssimply absorb sunlight and spit out electricity.
However, that electricity has a form that is not very useful to us: low voltage electricity and direct current. To make it compatible with our appliances, it travels through thick high-current cables to what is known as an inverter. Photovoltaic solar panels are made up of many small photovoltaic cells, which means that they can convert sunlight into electricity. These cells are made of semiconductor materials, usually silicon, a material that can conduct electricity while maintaining the electrical imbalance needed to create an electric field.
Because you're still connected to your traditional power company, you can get additional electricity automatically to supplement any solar power shortage off the grid. The current supplied by the solar panels flows into the house or into the grid through the house's electricity meter. This means that you simply plug one expansion pack into the inverter and then add additional photovoltaic panels instead of having to purchase and install an entirely new additional inverter. When light energy from the sun hits a photovoltaic solar cell, it energizes the cell and causes electrons to “let go” from the atoms inside the semiconductor wafer.
This is because photovoltaic panels work by releasing electrons from the semiconductor materials doped inside the cell that form a circuit and then return to the semiconductors inside the panel. While the details behind solar energy are very scientific, you don't need to be a scientist to convey the benefits that a solar installation can bring to a business or property owner. Once solar energy has been converted from DC to AC electricity, it passes through your electrical panel and is distributed inside the house to power your appliances. As heat is exchanged in the tank, water is pumped back to the solar collector (determined by a control unit).
A warning here; there is a specific shutdown procedure that must be followed when disconnecting the photovoltaic panels and/or the inverter: follow the instructions or, better yet, find a qualified installer to perform any maintenance work. Unless you have been completely disconnected from the grid via a storage solution, you will need to extract some power from the grid, especially at night, when your solar panel is not producing. This switch will simply prevent the solar system from supplying power to your inverter and the grid if there are any problems. Most homeowners don't know that residential solar panel systems are grid-connected, which means there is no battery backup system involved.
While solar panels generate direct current (DC) electricity, most electricity consumers need alternating current (AC) electricity to power their buildings. An experienced solar developer can guide you through these benefits and help you explore if a solar solution is right for your business. On cloudy days and at night, shingles or solar panels may not be able to capture enough sunlight to use as energy; conversely, in the middle of the day, when no one is home, they may collect more surplus energy than you need to operate your home.
