Use our solar cost calculator to learn why grid-tied solar is a sound investment. Let’s take a look at how this plays out for a typical home throughout the year: In summer, when the days are long and sunshine plentiful, homes with on-grid systems export more power than they import. Solar panels harness the energy of the sun by using photovoltaic cells to generate direct current (DC) electricity. Panels are rated by power output (in watts). Based on the scenario laid out above, a home with grid-tied solar panels will generate lots of excess solar power during the summer. The homeowner can then carry these credits over and use them during the winter, when their grid imports are higher than solar power exports. The biggest advantage of grid-tied solar systems is that they are much cheaper than other types of solar systems. Adjustable pole mounts make sense if you live in an area that gets heavy snow.

New to solar? If a grid connect system is producing more power than the home consumes, the surplus is fed into the power grid. But the sun isn’t very strong yet, so solar production will be limited, and the home still has to import from the grid. This is important because solar energy is intermittent: it stops working when the sun goes down. Evening: No more solar, so the system goes back to importing from the grid. Most Americans who have solar panels installed on their roofs have a grid-tied solar system; and despite recent improvements in battery technology, grid-tied remains the most popular option for homeowners going solar today. A quick note: This type of system is also known by many other names, such as ‘on-grid,’ ‘grid-connect(ed),’ ‘grid-intertied’ and ‘grid-direct’ solar systems. As sunlight hits the panels, they start generating power. A typical solar system consists of solar panels (which absorb sunlight), inverter (which converts DC into AC), mounting structure (that hold the panels in place), batteries (to store the extra power generated), … $6,291.07.
