Why Battery Storage Systems Work For Condominium Owners

Let’s explore the potential investment benefits a battery storage system offers condominium owners in California.

The Potential for Double-Digit ROI

Solar batteries aren’t just about saving on electricity costs; they’re also about smart financial planning.

Battery storage systems can be a game-changing investment for Condo owners with a potential double-digit Return on Investment (ROI).

The name “solar batteries” is misleading because you don’t need a solar panel system on your roof to take advantage of the financial benefits battery storage systems offer.

Using Battery Storage Systems In Condos Without Solar

Peak shaving is a crucial strategy that battery storage systems can effectively utilize, especially in states like California, where electricity costs are high.

It involves charging your battery storage system with electricity from the utility grid during off-peak hours when electricity rates are low. This stored energy is then used during peak hours when electricity prices surge.

The beauty of this strategy lies in the significant cost difference between off-peak and peak rates.

By using stored energy during peak hours instead of drawing from the grid, you avoid the higher utility rates, effectively ‘shaving’ off the peaks in your electricity costs.

In states with high-cost electricity, like California, this differential pricing strategy can generate double-digit returns on investment.

With peak shaving, you can make the most of the varying utility rates, turning them into an opportunity for substantial savings.

Peak-shaving makes battery storage systems an energy-efficient choice and a wise financial investment.

Condo Peak Shaving: No Solar Energy System Required

It’s important to note that peak shaving doesn’t require a solar energy system. While solar panels can provide additional benefits, the practice of peak shaving can be accomplished solely with a battery storage system. 

As stated, when rates are low, you charge the battery with electricity from the utility grid during off-peak hours. This stored energy is then available during peak hours, allowing you to avoid the high costs of peak times.

Most battery storage systems can be programmed to perform this “peak shaving” automatically.

This stand-alone strategy makes battery storage systems a versatile and valuable asset in managing your energy usage and costs, irrespective of whether you have a solar energy system installed.

How Batteries Help Condos That Have Solar Panels & NEM 3.0

California has mandated installing solar energy systems in all residential dwellings built after Jan 2022. This regulation provides an excellent opportunity for condo owners to reap financial benefits.

It’s worth noting that this mandate wasn’t just about installing solar panels; it included new requirements for HVAC, lighting systems, the building envelope, and more.

It’s about reducing the total electric load on the state’s electricity grid and encouraging a more self-sufficient residential energy model.

New Condo owners save money on electricity, and the state gradually reduces its electric load; it’s a win-win.

That worked out great for most Condo owners until Dec 2022, when California’s Net Energy Metering (NEM) 3.0 was enacted.

NEM 3.0 greatly reduced the credits homeowners receive when their solar energy systems send excess energy into the utility grid (also known as feed-in rates).

Under the previous versions, NEM 1.0 and 2.0, those credits were near the Utility’s retail price, but under NEM 3.0, the credits dropped by more than 80 percent.

If you purchased a Condo with a solar energy system after Dec 15, 2022, or are about to, you will be on NEM 3.0.

As a result, you will have a higher electric utility bill than those who purchased before you because you’re losing tremendous value for any solar electricity you send into the grid.

You’re now paying for off-peak power previously offset by feed-in credits (under NEM 1.0 and 2.0).

The solution in many cases, is a battery storage system, to save that excess electricity and use it when your solar energy system is not generating power. That saves you the difference in costs between high utility rates and your low-cost solar energy.

When a solar energy system is coupled with battery storage, you can maximize your savings by storing the excess solar energy rather than feeding it back into the grid at a lower rate.

Ease of Battery Installation in Condos

One might assume that installing such advanced technology might involve complex procedures. However, that’s not the case. Particularly if your Condo’s electrical panel is located in a garage, installation can be straightforward and hassle-free.

With the help of skilled and licensed professionals, setting up your solar battery storage system can be seamless. (Contact us for a free consultation if you’re in San Diego County, CA)

Solar For Condominiums Built Before Dec 15, 2022

If your Condominium doesn’t have a solar energy system installed, you may wish to investigate if you own space on the roof and can install solar panels if desired. Check with your CCRs and condo association.

If you don’t own the roof of your Condominium, then installing solar panels is not a feasible way to save electricity.

You could speak with the Condo management and see if they would be willing to explore investing in solar energy for the entire complex. Here’s a non-profit guide to converting your HOA to solar.

Otherwise, a stand-alone battery backup system is your best bet for electricity savings and the potential for a very good return on investment.

Additional Benefits of Battery Storage Systems for Condos

There are several other compelling reasons to invest in batteries for your Condo.

They provide a reliable backup power source during grid outages, ensuring continuous power supply.

Suppose you own an electric vehicle (EV) and can plug it into your Condo for electricity consumption. In that case, you’d also be eligible for the utility company’s Electric Vehicle Time-of-Use rate plan (SDG&E’s EV05 in San Diego), which could save you additional money.

Moreover, solar batteries enhance your energy independence, reducing your reliance on the grid. Utilizing clean, renewable energy also contributes to environmental sustainability, aligning with California’s green initiatives.


In conclusion, solar batteries represent not just a commitment to energy autonomy and environmental responsibility but also a smart financial investment for condo owners in California.

Solar batteries can maximize your energy savings, protect against outages, and positively contribute to the environment.
