The Road to Energy Independence: Maximizing Benefits
As the country is rapidly moving away from traditional methods of producing energy, such as fossil fuels, many are looking for ways to maximize and capture all the benefits when making the switch to solar. One popular way homeowners are ensuring that they get the most out of their solar system is pairing it with an Energy Storage System (ESS) to store excess energy generated.
Installation of ESS has increasingly been on the rise, with 21 percent of solar installation projects being paired with one in 2022 alone. Additionally, 81 percent of installers in the residential segment currently offer ESS installations alongside solar panels, making it the most popular service offered when installing a solar system.*
Why Consider an Energy Storage System?
There are many reasons why homeowners would want to opt for an ESS for their home when paired with a solar system, driving tremendous growth of these systems. Several of those key benefits include:
Energy Cost Savings: An ESS allows homeowners to store any excess energy generated from their solar panels during the day and utilize it when power generation is unavailable, during peak demand hours or when energy costs are high – all without pulling from the grid.
Peace of Mind: In the event of a power outage or natural disaster, an ESS can provide backup power to essential home devices and appliances. Like generators, an ESS can provide backup power in case of emergencies, but without the uncertainty of running out of an energy generating source.
Increased Home Value: Like solar panels, installing an ESS can increase the resale value of a home. As the demand for renewable energy increases, a turnkey solar plus storage system will make a home more attractive to potential buyers.
Government & State Incentives: Depending on local jurisdictions, homeowners may qualify for incentives when installing an ESS, reducing the overall investment cost and making it more affordable.
What Do Energy Storage Systems Do?
Energy storage is essential to the transition to clean energy. Energy storage maximizes the value of energy by saving the inexpensive excess power that is generated by renewable energy sources, and deploying them when solar is not available and power from the grid is expensive. Energy storage localizes Energy Storage Systems, so that less power is lost in transmission and distribution.
Distributed Energy Resources (DERs) such as ESS allow for users to be able to store and use their own power instead of drawing from the grid, reducing stress on the grid. Instead of a centralized power plant having to produce power at the same time it is being consumed, decentralized ESS allows for energy to be stored and then deployed when it is needed.
How Do Energy Storage Systems Work?
Energy Storage Systems store DC power and convert it to AC using an inverter so that it can be used. Lithium-ion batteries are the most popular form of ESS because they can hold a charge for longer, and are relatively efficient. Most Lithium-ion Energy Storage Systems utilize battery cells, a Battery Management System (BMS), and an Inverter. Increasingly, we see ESS paired with solar because they help make solar power more reliable by firming up any gaps that may arise between solar energy supply due to clouds or time of day.
The Rise in Demand of Energy Storage SystemsAs the demand for renewable energy rapidly grows, the need to store excess energy generated also increases. Here are a few reasons behind increase in demand of ESS:
Net Metering Restrictions: With the increase of net metering restrictions, such as the recent passing of NEM 3.0 in California, homeowners are being compensated at a much lower rate than before for the energy they are sending back to the grid. An ESS allows the homeowner to retain the full value of their excess energy generated.
Increase in Grid Outages: An increase in grid outages in recent years are prompting homeowners to find a way to retain power in the event of an outage. Several factors for outages include an aging infrastructure, increased demand and natural disasters.
Rise in Utility Costs: As utility costs constantly rise and fluctuate, homeowners are looking to decrease their reliance on the grid as much as possible. A solar+storage solution will reduce, if not eliminate reliance on the grid.
