How Does Solar Power Feed Back Into The Grid?

The solar power industry is growing and solar panels are becoming more affordable. Many homeowners want to make the switch but don’t know where to start. In this guide, we will answer some questions about solar power and how it feeds back into the grid!

The easiest way to explain how solar power feeds back into the grid is that it is sending excess energy you created from your solar panels. The solar panels store energy into the connected battery. When you don’t need it, excess solar power can be sent back to the grid for others to use!

How to Connect Solar Panels to The Grid

To connect solar panels to the grid, you need to install grid-tied solar panels. Grid-tied solar panels work in tandem with your local utility grid, which means that whenever there is an excess of energy generated by the system it will feed back into the grid for others to use.

The grid-tied system also includes a bi-directional meter. This allows you to draw power from the grid when necessary while making sure that your house is not using more energy than it’s producing at any given time.

To maximize solar panel efficiency and ensure net metering benefits, your grid-tied solar panels should be installed by a qualified installer.

Do Solar Panels Have to Be Connected to The Grid?

No, grid-tied solar panels are not the only option for homeowners who want to produce their own energy. For those who have a strong preference against being connected to the grid, there is another viable solution: stand-alone power systems.

Stand-alone power systems operate independently from your local utility grid and do not need any other type of connection. Stand-alone power systems tend to be simpler and less expensive than grid-tied solar power panels, but they do have some drawbacks.

If you use a stand-alone system, any excess energy produced by your solar panels will not feed into the grid for others to use. Instead, it stays in storage until you need it at home or on the go.

For grid-tied systems, the costs of installation and maintenance are typically offset by net metering benefits where you can earn money for excess energy fed back into the grid. 

Stand-alone power systems do not offer these types of returns on investment unless you decide to sell your excess electricity directly to others in your community.

What Is Net Metering?

Net metering allows residential and commercial customers who generate their own electricity from solar power to sell the excess they aren’t using back into the grid.

The great part about using net metering is if you happen to produce more electricity than what you used during a day/month/year, any extra solar power will be sent out onto the electric lines of utility companies in your area so everyone else can benefit from it!

You may even get paid by certain utilities for sending them solar energy (it all depends on where you live).

There are also some things homeowners should know when solar panels are feeding into the grid. First, you should make sure you have a solar inverter in your solar power system that converts DC current to AC voltage so it can be used by other people in your area (some homes run on DC energy).

It is also important to keep track of how much electricity was sent out onto the electric lines and how much solar energy you were using at home because this will determine if there’s any money owed for excess solar power usage.

Can You Make Money with Net Metering?

Every grid-tied system has what is known as a “feed-in rate” – the maximum amount of energy that can be fed back into the grid. This number varies depending on where you live, but it will typically fall between $0.15 and $0.25 per kWh (kilowatt-hour).

The feed-in rate can be a little complicated to understand, but it is the amount of money you will receive for every kWh fed back into the grid. For example:

If your feed-in rate is $0.20 per kWh and an average home sells 900kWh in a given month, then you would receive $180 from net metering at the end of that month.

How Much Solar Can I Feed Back Into the Grid?

The amount of solar that you can feed back into the grid depends on how much energy your local utility company allows. Some companies allow for 100% net metering while others only offer 50%.

As more people install grid-tied systems in their communities, grid operators are forced to carefully monitor grid capacity and prevent blackouts during peak hours when grid demand is high.

As this grid capacity decreases, solar owners may be limited to how much energy they can feed back into the grid.

In addition, some locations such as Hawaii and Arizona do not offer net metering benefits at all because of their abundant access to renewable resources like wind and geothermal power. In these areas, stand-alone power systems may be the only option.

The grid-tied system will calculate how much excess solar you can feed back into the grid based on your energy consumption and local utility regulations.

How Long Does It Take to Connect Solar to The Grid?

The grid-tied system will take approximately two weeks to connect your solar panels and have them fully operational. This includes the installation of a bi-directional meter, grid interconnection paperwork, inspection by a licensed electrician, etc…

During this time you will need to be connected to the grid from an alternate source such as solar battery backup or grid power.

If you are switching from grid-tied to stand-alone, it will also take approximately two weeks for your solar provider to complete the installation of a new system and have it fully operational.

Why Is My Solar Not Feeding Into the Grid?

If you are connected to the grid through net metering, it is unlikely that your solar will not feed into the grid. Net metering regulations vary by state but typically require grid-tied systems to send excess energy back into the grid first before using any of their own electricity.

If you are experiencing a problem then it is possible that your grid-tied system is not working properly or you are using too much energy to qualify for net metering.

If this problem persists, it may be helpful to contact your local utility provider and see what they can offer in terms of assistance. Grid operators make special allowances for customers with grid failure issues if their grid-tied system is no longer working.

If you are switching from grid-tied to stand-alone, it may be helpful to contact your solar provider and discuss the possibility of an upgrade if you want more energy independence or backup power options during grid failure.

Final Thoughts

Solar power is a renewable energy source that can be grid-tied or stand-alone.

If you want to make money with net metering, it’s important to understand your feed in rate and what percentage of solar power can be fed back into the grid in your area.

Connecting solar panels typically takes approximately two weeks but may take longer if you are switching from grid-tied to stand-alone systems because an electrician will need time for inspection and installation.

If grid-tied solar is not feeding into the grid, then there are two possibilities: either your grid-tied system is not working or you may need to upgrade if you want more independence. If any problems persist, contact your local utility provider for assistance.
