How Does Solar Energy Work
What Is Solar Power?
Solar Energy is when you obtain electricity from the sun, it is basically an inexhaustible resource because as long as we have the sun we are able to harness its energy. Also having a solar power system installed means you don’t have to worry about the cost of electricity increasing.
Solar power is also a clean alternative to fossil fuels. Fossil Fuels are an ever increasing threat to our public health and safety and is believed to play a prominent role in global warming.
What Are Solar Panels?
There is an abundance of energy flowing around us all day, every day. The sun generates an enormous amount of energy in the form of heat and light, and projects it at the earth. We mostly just use this energy to be able to stay warm, and see during the day, but it can be doing so much more. By using solar panels, we can capture the light waves, and convert it into electricity.
A solar panel is usually comprised of many cells that are all connected together. One of the most common types of solar cell is the photo-voltaic (PV) cells, which are made from specially designed semiconductor crystals.
The solar module or panel has a non-reflective glass front as well as a protective insulating back sheet with aluminum fame. This allows increased strength and mounting ability.
Usually, the more panels you have, the more electricity is generated. But placement of the panels is also a key factor. It’s important they receive as much sunlight as possible. Which is why they are installed on rooftops or other such open areas.
Because of their reliance on the sun, solar panels only generate energy during the day. But this does not make them useless to people who use the majority of their energy during the day. You are able to sell energy back to the grid during the day and actually make money while you’re out of the house. In addition, you can add a battery so your system, and store energy generated for later use.
What Is An Inverter?
The inverter functions as a transformer, it can take the direct current (DC) that is produced by the solar panels and transform it into the Alternating Current (AC) electricity that is used to power most standard equipment that can be found in the home or office. It can also automatically shutdown the solar electric system in the situation when there is a power failure.
There is an AC safety switch which is a manual disconnect switch that can be used when there is a need to disconnect a building’s electrical system from the solar electricity system.
The solar power systems performance can be monitored by accessed through the inverter or alternatively by reading your electricity meter.
