How does Energy Conversion work with a Solar Micro-grid

Solar panels are comprised of photovoltaic cells that react to UV rays and transform them into electricity. Each cell is made of silicon conduction materials, which are highly reactive to solar energy.

The gases and elements of the sun are highly reactive. Protons from these materials are constantly moving from the sun to Earth. When these protons come in contact with certain elements on Earth, such as silicon, a chemical reaction occurs.

The protons from the sun’s rays cause the electrons to escape from the atoms that make up silicon. This generates an electric current.

The energy of these moving atoms can be converted into a clean power source via wires threaded throughout the solar panel system. These wires convert the energy from the moving electrons of the silicon into electricity that can be used to power just about anything.

Energy Storage

Solar panels themselves do not store energy; electricity is merely created within the cells and then transported through conductors to an electric device, such as a lightbulb.

However, solar panel systems can be hooked up to special batteries which are able to store this energy for later use.

Since solar panels can only create energy when they are in contact with UV rays, the panels are not generating power during the night. This is why power storage units are often used in conjunction with a solar panel system.

These batteries can store extra electricity that is produced on sunny days so that it can either be used at a later time or sold back to the power company.

A solar micro-grid is an increasingly popular technology that’s giving homeowners, businesses, and entire communities access to cleaner and more reliable power. Depending on its size, a solar micro-grid can be used to power one or multiple homes or facilities.

Suninone manufactures and uses leading solar technologies, include them in our systems to create a micro-grid energy system for your business application or village or town.

Micro-grids vs Solar Micro-grids: What’s the Difference? 

A microgrid is a local, independently controlled power grid that can integrate distributed energy resources (DERs) into the main electric grid or you can make your own grid.

Microgrids can distribute all kinds of energy resources, including renewable energy to fossil fuels.

A solar micro-grid is a specific type of micro-grid that generates electricity using solar power. A solar panel system complete with battery storage and backup generation is a type of solar micro-grid.

How Does a Solar Micro-grid Work?

Solar micro-grids can be connected to the main electric grid and can integrate with it. They can also separate from the grid and operate independently.

A solar micro-grid maintains a connection to the main grid until it is necessary to switch to independent power generation or “island mode.”

This usually happens during a period of high electricity demand or during a power outage. The switch happens seamlessly, and you may not even notice that your system has gone into island mode.

You can also use the system in Island mode all the time. This allows you to run off-grid without depending on the grid or the rising cost of electricity from the grid.

How You’ll Benefit from a Solar Micro-grid 

There are many benefits to solar micro-grid technology, including:

  • Power during an outage.
  • Less reliance on fossil fuels.
  • Greater energy independence.
  • Lower electricity costs.
  • Improved grid resiliency.

Why are you doing a Micro Grid?

  • Configure and compare a variety of scenarios to analyze technical performance.
  • Validate micro-grid system design and logic incorporating historical, present, or forecasted conditions.

Operational Resiliency

  • Safeguard against power interruptions.
  • Proactively adapt to system changes, unexpected events and disturbances.

Decarbonization & Decentralization

  • Demand for effective energy sustainability and carbon footprint reduction.
  • Effective management and optimization of distributed generation and load assets.

Lower the Cost of Engineering, Operation & Maintenance

  • Reduce the total cost of ownership (TCO) by reducing the cost of electricity (COE).
  • Manage and decrease the Operations & Maintenance cost.
  • Ensuring that supply and demand are met and optimized at all times within the agreed and empowered electricity prices and programs.

The Benefits of Solar Microgrids

Implementing a microgrid provides facilities with clean energy at a lower cost than conventional power generation.

Cost savings and emergency backup power are two major advantages to solar microgrids. Still, the largest advantage is the control owners have over their facilities and the significant energy savings that can be achieved.

Here is a breakdown of the major benefits owners can expect from microgrid systems:

  1. Lower Electrical Utility Costs:

    A microgrid reduces utility costs by either disconnecting from the grid or using power from the grid at times of lower cost.

    While solar power may not be enough to supplement all energy costs completely, owners can secure long-term natural gas contracts. In ideal situations, heat recovery can also help reduce gas consumption as well.

    Solar microgrid systems are flexible. They allow different configurations to provide the most energy savings and protect against utility rate spikes and changes.

  2. Meet Payback Goals (Net Positive)

    Solar power today is now at grid parity.

    For owners whose utility rates are based on kWh consumption, solar power is equal to the cost of power from the grid. Therefore, owners will not pay higher rates for producing solar energy.

    With the ability to net meter, owners can see positive cash flows in the first year under these rate structures.

    Owners who buy power with lower kWh costs but high demand costs can use a micro-grid system to reduce demand costs. This can also lower the amount of kWh consumed from the grid.

    Depending on the cost of demand, micro-grids can show higher annual net savings than a renewable energy system alone.

  3. Stable Source of Energy:

    Energy independence should not be understated here. A micro-grid ensures that a building, plant, or application has backup energy storage.

    This local energy production can be adjusted to meet federal and state energy storage requirements.

  4. Reduce Environmentally Dangerous Emissions:

    Utilizing renewable energy is a major function of micro-grids.

    Reliable solar power systems offer favorable financing solutions while reducing fossil fuel emissions found in conventional power generators.

    Additionally, power production independence can help reduce reliance on conventional power sources.

  5. More Efficient Power Systems:

    Producing your power locally is more efficient than purchasing it from the utility company.

    There is a large amount of line loss due to the distance electrical energy must travel from the utility company to a facility.

    Solar micro-grids allow owners to take back control of their energy systems from the utility company and achieve energy savings.

    These systems are flexible, clean, efficient, and cost-effective energy options for facilities.

What the IRA Means for Utility and Remote Micro Grid Projects

Significant funding through the Inflation Reduction Act (IRA) for rural electrification and clean energy has significantly reduced the cost of Remote Grid Standalone Power Systems, enabling cheaper and scalable Remote Grid deployments for more utilities.

New grant and funding programs included within the IRA now make it easier for both large and small utilities to develop solar and storage systems in remote areas, as many of them are dedicated to rural and underserved communities. 

One of the largest components of the IRA is the extension of Clean Energy Investment Tax Credits (ITC), which now includes standalone battery storage.

Here are some core benefits:

  • Through 2035, utilities can save up to 30% of costs in the form of tax credits.
  • Utilities that qualify can earn stackable bonus credits if the respective project is under 5 MW.
  • Projects can earn an extra 10% in ITCs if they are located in a low-income community or Tribal land, or if it meets the IRAs domestic content requirements.
  • Reinstated Production Tax Credits (PTC) associated with energy generated from renewable sources like solar, in which case the credit rate is 2.6 cents per kWh.

As a part of the IRA and the Infrastructure Investment and Jobs Act (IIJA), the Grid Deployment Office has put forth several grants related to grid resilience that can be leveraged for Remote Grid projects:

Grid Resilience Formula Grants

  • Invests $2.5 billion in states and Tribes to modernize grid infrastructure and increase renewable generation and distributed energy resources.
  • Applicable uses under the program include a range of resiliency measures, which include the use or construction of microgrids and battery storage subcomponents, for enhancing system adaptive capacity during disruptive events.

    Grid Innovation Program

  • Provides $5 billion in financial assistance to one or multiple states, Tribes, local governments, and public utility commissions.
  • Supports collaboration with electric sector owners and operators to deploy projects using innovative approaches to transmission, storage, and distribution infrastructure.
  • Helps enhance grid resilience and reliability.

The IRA and IIJA also include funding programs dedicated to electrifying rural and remote areas with clean energy.

Similarly, these programs can subsidize the cost of deploying Remote Grids: 

Rural Renewable Energy Loan Program  

    • Provides $1 billion in guaranteed loan financing and grant funding to agricultural producers and rural small businesses for renewable energy systems or to make energy efficiency improvements.

The Energy Improvement in Rural or Remote Areas Program 

    • Provides another $1 billion to rural and remote areas.
    • Helps improve resilience, safety, reliability, and availability of energy.
    • Helps increase environmental protection from adverse impacts of energy use in coordination with the Department of Interior.

Rural Energy for America Program

 

    • Offers $2 billion in grants and guaranteed loans for developing clean energy systems.
    • Supports energy-efficient infrastructure such as lighting, insulation, cooling, and more for farmers, ranchers, and rural small businesses.

Rather than the traditional utility model of building and maintaining costly and sometimes risky distribution lines, utilities can leverage these funding sources to give rural regions clean and resilient solar standalone power systems.

These programs, combined with the fact that microgrids can already be more cost-effective than replacing or hardening rural distribution lines, make deploying Remote Grids in high fire-threat zones more financially attractive to utilities in the Western U.S.

The IRA and the IIJA are historic investments in the fight against climate change.

Remote microgrids already have a strong track record of providing clean and resilient energy. The financial incentives for solar plus storage deployment can allow both small and large utilities to take on more of these projects in the future.
