These payments allow the homeowner to dramatically reduce, or even eliminate, their utility usage charges. Where available, net metering lets homeowners earn bill credits for every watt of excess solar energy they send back to the grid. Can grid-tied solar systems use net metering?Ī grid-tied system’s two-way relationship with the grid offers homeowners a major benefit: they can use it to take advantage of net metering. When the solar panels aren’t producing enough electricity, the system can import the shortfall from the grid. It also means that the house doesn’t run out of power. With grid-tied systems, this excess power is exported to the utility, which earns electric bill credits for the homeowner. This is also when solar panel production is at its peak, so power generation far exceeds energy use. In most households, energy usage during the day is relatively low as members tend to be out of the house. How grid-tied systems manage power surpluses and shortfalls What happens to excess solar power production? You can start by entering your details below. It’ll tell you everything you need to know about installing solar panels in your home. To see a live price for a solar panel system customized for your home, I recommend you use our advanced solar calculator. *Average cost after deducting the federal solar tax credit incentive as of 2023 In the table below, we take a look at how the average price of grid-tied solar panels varies by system size. However, solar system costs can vary a lot based on many factors, such as system size, the state you live in, the brand of solar panels you choose, and even the pitch of your roof. Most systems cost between $2.75 and $3.35, with a national average price of around $3.00 per watt as of 2023. The average cost of a typical grid-tied solar system is between $12,600 and $14,000 net of the federal solar tax credit. How much does a grid-tied solar system cost? This makes grid-tied solar systems both cheaper and simpler to install. No batteries needed: They don’t include any form of energy storage to store solar power.The grid-tie inverter can intelligently manage the solar panels so that their power is first sent to supply your home before exporting the excess to the grid. They use grid-tie inverters: Grid-tied solar systems require an inverter that can communicate with the grid these are known as grid-tie inverters.Here’s how grid-tied systems are different from other solar panel setups: The solar panels are installed at a location with suitable sun exposure – typically on the roof, but other sites like your backyard can also work – and require wiring to transport electricity between the solar equipment, the home, and the power grid.
