How Residential Solar Systems Generate Electricity
We all want to use the sun as a renewable energy source to benefit the planet – and we all like the idea of lower electric bills! Minnesota Solar energy systems can dramatically reduce home energy use and create a source of income for many homeowners. If your roof, yard or garage has a year-round sunny spot, it has the potential to generate electricity from a solar energy system. Solar energy can be an affordable way to move toward energy independence.
How Residential Solar Systems Generate Electricity – Lets save money
Once solar panels are installed on your roof and begin to create energy, there are a few steps required to turn it into energy your home can use. As the sun hits the solar panels, they generate direct current (DC) electricity, where the electrons flow around a circuit in one direction. In order for your home to use this energy, it must be converted from DC electricity to alternating current (AC) electricity, where the electrons are pushed and pulled. When you have solar panels installed on your home, you will also have a solar inverter installed. The solar inverter changes the DC output of the solar panels into AC electricity that your home can use.
How Residential Solar Systems Generate Electricity – Net Metering
When your solar panels produce more energy than your home needs at any one time, you may wonder where that energy goes. That energy is sent back to the power grid and you get credit for it on your utility bill. This process is called net metering, and it’s one of the great things about solar. In essence, your roof is producing energy and sending the excess back into the utility grid through the meter on your home. This allows you to benefit from all the energy your home produces. When your home needs more energy than your solar panels are producing, you can use the energy credits from your excess energy to reduce your energy bill.

Here’s how solar power production works: Sunlight strikes the PV cells on the solar panels, which causes the electrons to flow, creating an electric current, or a photovoltaic effect. The electric current produced by solar panels is direct current, or DC
There are a variety of solar monitoring systems, and most are associated with solar inverters. Common brands of solar inverters include Fronius, SolarEdge, SMA America, Enphase Energy, and Tigo Energy. Each of these companies typically offers proprietary monitoring software that integrates with their inverters.
Solar panel systems are measured in terms of kW. A common size solar panel array is usually around 5kW and takes up around 400 square feet of space. An array of this size can produce an average of 350-850 kWh of AC energy per month. To put that into perspective, a typical household uses about 897 kWh per month.
Benefits of Residential Solar Systems
A solar electric system provides an opportunity for anyone who is looking to reduce monthly utility bills and make a long-term, low-risk investment
