Advantages Of Using A Grid
The grid-tied solar system features several benefits, including
It is economical
With the grid-tied system, you will save more money since it is very efficient, has net metering, and requires low-cost equipment to install. This system omits the use of a battery, which tends to be very expensive. The best part is that its maintenance cost is very affordable since there are no batteries required.
The grid works as a virtual battery.
There is no doubt that electricity needs to be utilized in real-time. However, this is often not the case thus, you will need to store the extra power. When using the grid system, the grid will act as a virtual battery allowing excess electricity to be kept temporarily as a result, you omit the use of a battery.

Why Do Power Outages Happen
Sure power outages are pretty inconvenient for your lifestyle, but have you ever wondered why power outages happen?
Lightning is one of the most damaging causes of outages, but other weather related occurrences like heavy winds, rain, snow or ice also could wipe out your power.
Car accidents can also lead to power outages if poles or power lines are damaged.
If natural causes werent enough, your utility company regularly plans routine outages for maintenance.
And to top it all off, even one tiny squirrel could wipe out energy for an entire neighborhood!
All these reasons are just regular things that could cause outages. If you live in an area prone to hurricanes or other natural disasters, you know the damage that is caused by being out of power for days, weeks or months. And in the recent years, power outages have been on the rise.

If you own and use a solar panel, then chances are you will feel a certain level of independence regarding the energy situation in your area.
So maybe you are wondering what occurs to solar panels when the power goes out. Does it affect you as well? Or does the presence of your sun-powered knight in shining armor exclude you from unprecedented situations like blackouts? Lets see!
How Long Can A Battery Keep My Home Running
“An EverVolt battery system can provide power to select backed-up loads for about 6 to 9 hours, without solar charging the battery during this time,” says Kumar. “You can prolong this with additional batteries and if you have solar panels you can expect battery charge to increase about 10 percent in a span of 30-40 minutes.”
In an outage, it’s your essential loads that automatically receive power. And while you can turn these appliances on and off to conserve electricity, you can’t change which devices are backed-up unless you have a smart panel, which can be installed alongside your battery storage system.
A smart panel is controlled from a mobile app and gives you visibility on which appliances are being powered and how much power they are consuming. You can turn appliances on and off from the app too. This means you don’t have to decide upfront which devices you want in your essential load.
Batteries powered by solar panels can keep your home running even when an outage lasts for several days. And while it is possible to back-up your whole home, just one or two batteries can easily give you what you need to stay comfortable and keep working with minimum interruption.

If I Have Solar Panels And A Battery Will I Have Power During A Blackout
If you have a home solar + battery storage system, you can use your battery to power your most needed lights, outlets, and appliances during a power outage.
When the power is out:
- A battery can power your most needed lights and appliances. If youre a Sunnova customer, when your battery is installed, you may be asked to choose critical loads that are important to power during a blackout i.e., a fridge/freezer, select outlets, a garage door opener, a fish tank, etc. Your battery will power your critical loads.
- During the day, if the sun is out, your solar panels can keep producing power from the sun and excess energy can charge your battery.
Even if the power is out for several days, your battery can continue to charge and power your home:
- During the day, if the sun is out, your solar panels can continue to power your most needed lights and appliances and charge your battery like usual.
- When the sun is down, you will only be able to power your most needed lights and appliances with the energy stored in your battery until your battery is depleted.
Will Solar Panels Work In A Blackout
Most solar panels won’t work in a blackout. This isn’t because they are no longer capable of converting sunlight into electricity, but because of how most solar systems work.
The majority of solar systems are grid-tied systems, meaning they’re still attached to the standard utility grid. This is so solar panel users can still receive electricity from their utility company if the solar panels fail to generate enough to meet demand and so they can sell excess solar energy to the utility company.
Most solar systems are connected to the grid via a solar inverter. This is a meter that measures and tracks the amount of energy generated and used by your home. Most solar inverters tie you to the grid, so if the grid shuts down during a blackout, your solar panels also stop generating and providing electricity to your home.
This is in part for the safety of repair workers, who need to know that busted electric lines are not carrying electricity from solar panels.

Use A Solar Powered Generator
Because of the extremely high price tag of solar battery storage, most people cannot entertain that sort of backup option. However, there are other environmentally friendly backup options for solar panels, such as solar generators for energy storage.
Many solar generators work the same way as regular gas generators, but they are mainly used for single plug-ins. For example, you can use them to make sure your refrigerator keeps running, plug in a space heater, keep medical equipment running, or startup emergency lighting.
These options are portable and are charged with your solar panel system whenever the electric grid is working. The solar generator will stop charging whenever the power goes off since it is not a fully equipped solar storage system, but you can use it to power other small items.
One of the biggest benefits of solar-powered generators is that they are super affordable. Several companies offer these sorts of devices that only cost a couple hundred. So, they are a great way to save money!
Drawbacks
Because this is a portable option, solar generators cannot support your whole home like the previous two options. Instead, they can only support one or two items. This can be a major drawback if you are specifically looking for a backup option to support your entire home.
Our Verdict
If you are looking for an affordable yet environmentally friendly backup option, solar generators are the best option.
Why Dont My Solar Panels Generate Power During A Blackout
One of the key parts of a solar energy system is the inverter – or inverters, if you have microinverters or a large system with multiple strings. In a grid-tied system , the inverter must synchronize the timing of its alternating current frequency to the frequency of the electric grid AC power.
It does this by âlisteningâ to the signal from the electric grid and adjusting its frequency to match. If an inverter canât detect a signal from the grid, it will shut down automatically. If it didnât, it would send power into the grid and potentially electrocute utility workers who are repairing the grid and expect the electricity to be off.
Because of this feature, when grid power goes down, your power shuts down, even if thereâs plenty of sunlight for your solar panels.

Can I Use Solar Panels During Power Outages
Since a grid-tied solar system must turn off when the grid goes down, installing rooftop solar panels doesn’t guarantee that you will have power during a grid outage. However, if you combine your solar system with battery storage you can tap into stored solar power during a power failure. Some home battery systems, such as the Panasonic EverVoltTM, enable you to keep your solar panels running throughout a grid failure so they can maintain a charge.
Power Outages Make Solar Batteries A Necessity In California
A solar panel system alone isnt enough to ensure that your home can stay powered on during a blackout. There are some inverters that have extra power outlets that arent tied to the utility grid, allowing a home to draw power from those outlets during a blackout. But this can only occur while the sun is shining and because the power is highly dependent on the amount of sunlight the solar panels system is currently receiving, leading to power output that may vary throughout the day. This is why a solar battery makes more sense for most homeowners in California.
Adding a solar battery to your solar panel system will provide consistent power to your home during the event of a blackout. As long as your solar battery is properly charged, you can power your home even when the sun isnt shining, at a consistent throughput. The amount of power your Energy Storage System will provide to your home during a blackout is less than the amount of power that your home receives when powered by the grid. Therefore, until the size of batteries dramatically increase at an affordable rate, you will have to decide which circuits in your home should be powered during a blackout. Your highest priority household circuits being powered is known as your Critical Load, . You need to manage that power carefully since you need to ensure that you have enough electricity to power your home adequately until the next sunny day, where your solar panels can recharge your solar battery system.

Can Solar Power Be Used During Power Outage
Unfortunately, solar power on its own cannot be used during power outages simply because most solar energy systems are considered grid-tied solar systems. Therefore, you will need backup options to keep your home working as it should. That being said, off-grid solar systems can work during a power outage, but these systems are costly.
Still In Limited Supply
I had heard about the new 3000TL-US, 4000TL-US, and 5000TL-US inverters late last year, and heard that they would be shipping in the first half of 2013, but it turns out that we got one of the very first to be installed in the U.S. or at least in the Northeast. Demand is very high for these systems.
I suspect that within a few years, most grid-tie inverters will include this emergency-power option. I havent had to test it out yet, but will be ready for that ice storm this coming winter!

Bay Area Solar Power: Blackout Backup
There are generally three types of solar energy systems: on-grid, off-grid, and hybrid systems. Depending on the system you choose, your solar power can work during a blackout.
On-grid, or grid-tied systems, depend on a power company to work. Solar customers with a grid-tied system generally find that their system generates more energy than their home actually needs, and that they can sell their electricity back to the electric company. However, theres a catch: the surplus energy going from your home back to the power company keeps the power lines live even if there is a blackout. This would create a serious safety hazard for line technicians. For this reason, grid-tied solar energy systems will not generate electricity during a blackout.
Off-grid systems are not at all dependent on the power company, so if the power goes out for everyone else, your lights stay on. Generated power is stored in a battery system connected to your home. A backup generator is a good thing to have in case of inclement weather that prevents your system from generating and storing enough energy. Off-grid solar energy systems will generate electricity during a blackout since they are completely independent of a power company.
Battery Storage During A Blackout
If you want to know how to use solar panels during a power outage in the most cost-efficient way, consider solar backup battery storage.
A solar energy storage system collects energy from the panels and stores the unused portion in a battery. At the very least, you can use the solar battery during blackouts to:
- Light up your home
- Keep the fridge running
- Power up medical devices
However, battery backups dont provide enough juice for the average HVAC system, since that requires a lot to keep going.
How long your battery lasts depends on its storage capacity. The higher it is, the longer you can weather an outage, given conservative energy consumption. Most solar batteries have apps that let you monitor real-time usage.

Option : Solar Battery System
A solar battery bank consists of lead acid or lithium batteries that are used to store your excess solar electricity. The system includes a charge controller that monitors your batteries and charges them at the correct rate, preventing them from overcharging.
If your batteries are full, the excess electricity will be sent into the grid .
For a long time, lead acid batteries were the preferred choice of solar homeowners because the technology of lead acid is mature and the products are widely available, which helps to bring down the cost. Itâs used in many applications, such as car batteries, deep cycle marine and RV batteries, and golf carts.
However, the price of lithium batteries has plummeted in the past decade. Lithium ion batteries are used in laptops, cell phones, electric cars, and are now being deployed in massive battery banks by electric utilities. These utility-scale batteries are cost-effective enough that they are now competitive with natural gas, and are starting to displace gas turbine peaker plants.
Because of these market forces, lithium ion is now often lower cost and the preferred technology for home solar batteries. Still, lead acid batteries remain popular, especially among the DIY crowd who often seek out cheap deals for golf cart batteries and other types of deep-cycle batteries.
One reason that lead acid is still attractive is because the upfront cost is lower than lithium-ion. However, lead acid has a number of disadvantages:
