Choosing Between Grid-Connected and Off-Grid Solar Systems
For a normal house that uses 10,000 kWh each year, a grid-connected system might run $15,000 to $25,000 to set up. With net metering, you could save over $1,000 a year on bills.

As a rule of thumb, 25% of the cost is direct cost, while 75% is the requirement to fund network upgrades, per our note here. The cost of grid interconnection has increased substantially over time.
The cost of a grid-tied solar system can vary widely, depending on how big of a system you need, where you''re located, and what kind of solar tax credits are offered by your state.
A grid tie solar system''s cost can vary significantly based on the size and location, with the national average cost in the U.S. ranging from $15,000 to $25,000 before tax credits.
Learn everything about grid-tied solar systems: how they work, costs, installation, and benefits. Complete 2025 guide with real examples and expert insights.
All costs reported are represented two ways: Minimum Sustainable Price (MSP) and Modeled Market Price (MMP).
First, you''ll need a copy of your electric bill. Figure the average kW usage for a year and put the answer in the top box. Next use 100% in the “percent of bill to cover” field to get an idea of the proper size of
The average cost of grid-connected solar energy ranges from 3 to 5 dollars per watt, installation costs vary based on location and system size, financial incentives such as tax credits can
NLR''s Distribution Grid Integration Unit Cost Database contains unit cost information for different components that may be used to integrate distributed solar photovoltaics (PV) onto distribution systems.
With Unbound Solar''s pre-wired grid-tie systems you''ll be able to see what components are needed for your system and a ballpark figure of what you might expect to pay.
