Grid-tie solar is, by far, the most cost-effective way to go solar. Because batteries are the most expensive component of any solar system, but grid-tie solar owners can skip them completely! So how do grid-tie solar power systems work? First, let’s define what we mean by the “grid”. The grid is the utility company’s network of equipment that brings electricity from the power plant to your home or commercial building. If a building is getting electricity from the power company, it is connected to the grid. Grid-tie solar systems send the energy they generate into the grid, where it is stored for later use. Under a net metering agreement, the system owner receives credit for anything they generate, and they can make use of that energy at any time. It’s kind of like a bank account: sending energy into the grid is like making a deposit, and using electricity is like withdrawing against your account balance.

Off-grid solar is best for delivering power to remote locations where there is no access to a utility line. Folks who live off the grid are solely responsible for generating their own electricity. This is usually accomplished by building an off-grid solar system that can cover a day’s worth of electricity usage, with a backup generator to supplement production during long stretches of bad weather.

If you live on the grid, but you want protection from power outages, your best bet is a battery backup system. Backup power systems connect to the grid, and function like a normal grid-tie system on a day-to-day basis. However, they also feature a backup battery bank that takes over in case of outages. When grid power goes out, your inverter automatically disconnects from the grid and draws on energy stored in your battery bank, which will keep your appliances running when the grid goes down.

A solar annual maintenance contract (AMC) is a service that helps ensure your solar panels and system are working properly. It includes regular inspections, cleaning, and repairs. Preventative maintenance: Helps identify and fix problems before they become bigger issues. Prolongs system life: Helps maximize energy output and reduce unexpected repair costs. Peace of mind: Ensures your investment continues to perform well.
