solar system no battery?No problem!

Apr. 10, 2024

In today's evolving energy landscape, you may be intrigued by the idea of storing solar energy at home. However, you might question the necessity of a solar battery bank for residential solar systems. Can solar panels be utilized to power your home without the involvement of battery storage? In summary, it's indeed feasible. While there are unique benefits for households to have a solar battery backup under certain circumstances, it's not a mandatory requirement for all.

Operating Solar Panels Directly Without a Battery
In case a battery storage system isn't part of your immediate plans, there's no need to stress! Your solar panels can still be utilised to energize your home without the inclusion of a battery storage system. In reality, the bulk of residential solar systems operate without being connected to battery storage.

Here's the process:
The early dawn and dusk periods are usually characterized by diminished solar energy production but elevated energy consumption. These are moments when you're kick-starting your day or preparing dinner and helping out with the kids' homework. During these intervals, the demand for power spikes, yet the solar panels are either just beginning to generate energy or are winding down its production.

During these periods (and particularly at nighttime), homeowners with solar panels but without a battery storage system draw electricity from the grid. Consider the grid as an immense backup energy reservoir. However, during daylight hours, your solar panels are probably generating an abundance of energy to supply your home. Any surplus energy is transported into the grid to help energize your local community.

In layman's terms, when sunlight is abundant, you utilize your personal solar power and contribute the surplus to the grid. In the absence of sunlight, you tap into the grid's energy. This arrangement is known as a grid-connected system. You essentially use the regional power grid as a form of "energy storage" negating the need for an in-house solar battery bank. If you have self-contained battery storage, your transfer of energy to and from the grid will be minimal. You store and draw from your own energy, and the grid acts as a contingency to your primary backup.

Net energy metering

In states with net energy metering, you earn credits for contributing excess solar energy to the grid. These credits can offset the cost of grid energy used across the year. This implies that rather than purchasing power from the grid, your only expense is for the solar machinery. Once the equipment costs have been fully covered, your usage of electricity is absolutely free!

Is a Battery Needed for My Solar System?
In many situations, having battery storage is considered a "luxury" when using solar panels for domestic purposes. Nevertheless, there are increasingly more circumstances where having a solar battery bank can be advantageous, if not entirely essential.


Firstly, if you reside in a location that is prone to one or more of the following conditions, having a battery backup would be a wise decision:

· Unstable power grid

· Regular natural disasters

· Public Safety Power Shutoff events (PSPS)

In particular, if you have crucial systems in your house, such as medical equipment or an electric well pump, that requires power when the grid fails, a home battery bank is indispensable. For Californians in these situations, the Self-Generation Incentive Program (SGIP) offers rebates that cover up to 100% of the cost of battery storage.Florida is another state where the utility of solar and battery is heightened due to frequent and prolonged power disruptions.

Having an unfavorable net metering policy also contributes to the need for a battery backup system. Besides providing backup power, battery storage can also serve as a pathway to enhanced energy savings. Energy providers in numerous states are striving to abolish or substitute net-metering policies. For instance, in California, the proposed NEM 3.0 policy aims to diminish the value of solar exports by approximately 75%. Hence, having a battery would allow homeowners to store and use the solar power themselves, bypassing the need to export the surplus power back to the grid at diminished rates.

In California, solar owners now earn near 30 cents/kWh for excess energy. With NEM 3.0, it drops to around 8 cents/kWh, making it financially beneficial to store and use solar electricity via a battery bank. In places with no net metering, self-storing and using energy exceeds returning it to the grid. Battery storage thus becomes key in optimizing solar energy usage.

Can solar panels and inverters operate without a battery?
Certainly, when tied into the main electrical grid, your solar panels and inverters can function without a battery. Just be aware that systems linked to the grid often get disconnected during blackouts. This is to avoid the risk of electrifying the grid, which could endanger technicians working to restore power.


No batteries, how does solar function?

Solar systems without battery storage function by essentially using the power grid as a kind of "virtual battery." When your solar panels are generating more electricity than your household is using, that surplus energy gets sent back to the grid. Conversely, when your solar panels aren't producing enough (such as at night or during heavy overcast), your home will draw the needed power from the grid. This system ensures a constant supply of electricity, despite the inherent intermittency of solar power.With the method of net metering, property owners accumulate credits from surplus energy, which compensates for the energy they draw from the power network. This system empowers individuals with solar installations to effectively substitute their standard electricity expenses with lesser costs for their solar equipment.


How can one conserve solar power without the use of batteries?

In the majority of domestic environments, surplus solar power is "saved" in the local energy network. "Saved" here suggests it's utilized to energize homes nearby. Therefore, if your solar production outpaces your household's requirements, the additional energy is fed into the grid and allocated to power adjacent systems. This not only alleviates burden on the primary utility, but also mitigates strain on the grid due to reduced distance of electrical current transmission.
