![]() The output voltage is also adjusted slightly higher than the grid voltage in order for excess electricity to flow outwards to the grid. In addition to this, grid-tie inverters, also known as grid-interactive or synchronous inverters, synchronize the phase and frequency of the current to fit the utility grid (nominally 60Hz). Direct current (DC) from your solar panels is converted into alternating current (AC), which is the type of current that is utilized by the majority of electrical appliances. What is the job of a solar inverter? They regulate the voltage and current received from your solar panels. Grid-tie inverter (GTI) or microinverters.Standard grid-tied solar systems rely on the following components: There are a few key differences between the equipment needed for grid-tied, off-grid and hybrid solar systems. As a result, the efficiency of our electrical system as a whole goes up. At the same time, you help to mitigate the utility company`s peak load. In other words, more electricity (and more money) goes to waste with conventional battery systems.Īdditional perks of being grid-tied include access to backup power from the utility grid, in case your solar system stops generating electricity for one reason or another. Lead-acid batteries, which are commonly used with solar panels, are only 80-90% efficient at storing energy, and their performance degrades with time. The electric power grid is in many ways also a battery, without the need for maintenance or replacements, and with much better efficiency rates.Īccording to EIA data, national, annual electricity transmission and distribution losses average about 7% of the electricity that is transmitted in the United States. You can use the utility grid as a virtual battery ![]() This makes grid-tied systems cheaper and simpler to install, and also means there is less maintenance required. Grid-tied solar systems are the only type of solar system that don’t require a battery to function. Lower upfront costs and ease of installation Learn more: How does net metering work 2. Without it, residential solar systems would be much less feasible from a financial point of view. Net metering plays an important role in how solar power is incentivized. As a homeowner, you can use these payments from your utility to cancel out your electricity usage charges - by up to 100%. Many utility companies are committed to buying electricity from homeowners at the same rate as they sell it themselves. With net metering, homeowners can put this excess electricity onto the utility grid instead of storing it themselves with batteries. Your solar panels will often generate more electricity than what you are capable of consuming. Benefits of grid-tied systemsĪ grid connection will allow you to save more money with solar panels through net metering, lower equipment and installation costs, and better efficiency rates. This electricity is first used to service the home loads, while all surplus energy is exported to the grid in return for electric bill credits. We highly recommend getting professional installation by a certified solar installer and/or master electrician and should plan on potential costs associated with this as well.Grid-tied, on-grid, utility-interactive, grid intertie, and grid backfeeding are all terms used to describe the same concept – a solar system that is connected to the utility power grid.ĭC electricity generated by the solar panels is sent to the inverter, which converts the power into AC electricity. You will also be responsible for optional components like current surge limiters and additional parts you may want to add. *Please note: You will need your own installation tools along with grounding rods and copper grounding wire as well as solar panel racking if necessary.
