They will advise you on the best equipment for your location and home. Your solar installer should be able to guide you through the interconnection process as part of their installation service. When applying for interconnection, you will need to make sure that your solar power system meets safety and regulatory standards. Homeowners should review their utility company’s interconnection standards to determine what permits, insurance and limits there might be on the power you can sell back.īefore you can sell back solar power to the grid, you will need to apply for what is called interconnection with your local utility company. Do I Need Additional Equipment To Add Power Back To The Grid?īesides your solar panels and battery backup power, you are likely to need additional equipment to send power back to the grid. They can either be sold directly to the utility company or to specific SREC brokers. These SRECs are separate from the actual electricity that is provided from your solar system. SRECs are performance-based solar incentives that “count” toward a state’s percentage of renewable energy in other words, homeowners can get credit for contributing renewable energy back to their state’s grid and helping their state rely less on nonrenewable sources. If you live in an eligible area, you may get one Solar Renewable Energy Certificate ( SREC) for each 1,000 kWh (or 1 megawatt hour) of energy production by a solar energy system. To prove that they are meeting the requirement, utility companies can use their own renewable power plants or purchase renewable energy credits. Many states and other jurisdictions have passed legislation requiring utility providers to source a specific percentage of their power from renewable energy sources like solar energy to reduce fossil fuel emissions. Solar Renewable Energy Certificates (SRECs) Check with your local utility company to see what types of programs they offer in your area. Where net billing is different is that the rates for selling and buying power may be different. Net purchase and sale, sometimes called net billing, is similar to net metering in that you might both sell and purchase power from the grid. This can make solar power a cost-effective way to reduce your monthly utility bills. You are only charged for the difference between power you use from the grid and the power you sell to the grid. With net metering, any excess power that you generate is sold back to the utility grid. If you have solar panels generating electricity at your home, you may generate extra electricity during peak daylight hours. Many utilities offer a way to sell solar power back to the grid called net metering. Which option works best for you will depend on your particular solar setup as well as the utility company in your area. If you want to sell solar power back to the grid, you have a couple of different options. Selling Back Solar Power To The Grid: The Options Off-grid systems are responsible for all of your energy usage with no backup, and no way to sell solar power back to the grid. When you have a stand-alone or off-grid system, that means that you are self-sufficient and have no connection to any electric grid. In the case of energy and grid independence, you could still choose to remain connected to the utility grid, either as a backup or to sell excess power. Grid independence means that you no longer rely on utility companies to supply your power. Being energy independent just means that you generate enough power for your own needs. These three terms all relate to generating your own power, but they have slightly different meanings. Advancements to energy distribution systems mean that you can also sell any excess power that you generate back to the utility grid. This can allow you to buy power from the grid if you use more power than you generate.
Grid-connected energy refers to having your own solar energy system at your home while still being connected to the main power grid. This interconnected apparatus is collectively known as "the grid."
#Connecting independent solar grids to grid series#
Solar, hydroelectric, nuclear, wind turbines and other forms of power generation are connected to homes and businesses across the nation through a series of power poles, transformers and substations. The electrical grid is simply the system that connects energy users to the electric generation and distribution system. Remaining connected to the utility grid allows you to generate your own energy while selling your extra solar electricity back to your local utility company. Grid independence, or being completely off the grid, may be feasible if you live in a remote area, but for many residential homeowners with solar energy systems, it still may make sense to remain connected to the existing utility grid.
