What Other Situations Should I Consider Before Buying Solar Battery Storage
While cost and savings are important, different circumstances could make a battery more attractive. For example, if your state is prone to power outages like California, having a backup battery will help keep your lights on.
Or, if you are interested in only using renewable energy, a backup battery will help reduce your reliance on the grid.
How Much Will You Save
Once you know how much a solar power system will cost upfront, and how much energy it will produce, you can predict how much you can save in energy costs per year.
This is another tricky calculation, however, because a lot depends on how you pay for electricity at the moment. Utilities often charge residential consumers a flat rate for electricity, regardless of the time of consumption. This means that instead of offsetting the expensive cost of peak electricity production, homeowners’ solar power systems merely offset the price they are charged for electricity, which is much closer to the average cost of power production.
However, many utility companies in the U.S. have introduced pricing schemes that allow homeowners to be charged at different rates throughout the day in an attempt to mirror the actual cost of electricity production at different times: This means higher rates in the afternoon and lower rates at night. A PV solar array may be very beneficial in areas where this sort of time-varying rate is used since the solar power produced would offset the most costly electricity.
Exactly how beneficial this is for a given homeowner depends on the exact timing and magnitude of the rate changes under such a plan. Similarly, utilities in some locations have pricing schemes that vary over different times of the year due to regular seasonal demand fluctuations. Those with higher rates during the summer make solar power more valuable.
Are Solar Panels And Batteries Worth It
Solar panels are definitely worth it. Every year we conduct a full financial comparison, and domestic solar power currently works out at an average 10p/kWh lifetime cost. The equivalent expected average grid cost over the systems 25 year lifespan is 36p/kWh.
Batteries dont offer such a clear cost comparison, but give you the benefits of using more solar at home, insulating yourself against grid costs and power cut protection. Whether you want to invest in a battery alongside solar PV is a personal choice, but its worth making sure it is sized correctly for your PV system and usage requirements.

Home Resale Value Increase
Were often asked if solar panels increase property value. Since a solar energy system is an asset just like any other, it does add to the value of your home.
However, this is only true if you own the system, rather than lease it.
A well known Zillow study shows us that homes with solar installations tend to sell for about 4.1% more than homes without.3 The value added will depend on the system size, quality and age of the installation.
As a bonus, if your state offers a property tax exemption for a solar installation, you wont have to pay the additional property taxes on the boost in property value provided by solar.
Is Solar Power Worth It
Once you’ve worked through all of these calculations, you’ll likely end up with a single numberthe number of years it will take for a solar system to pay for itself in savings from your energy bills. If you live in a sunny part of the country and have high utility bills at the moment, you could be looking at a system that will reach this point in five years. Other homeowners may have to wait 10 or 20 years to reach this point.
In other words, most homeowners will eventually see a benefit from a solar power system it might just take decades for this to be realized. Whether it is worth installing such a system therefore often comes down to a number of much less technical factors than those we’ve listed above: how long you are going to stay in your home, the subsidies available in your area, and simply whether you want to do your bit for the environment.

Is It Worth Getting A Battery With Solar
Solar battery storage is useful in homes that depend on solar power for their daily needs. It can work as a battery backup system and allows you to have energy independence.
These battery systems allow homeowners to store energy during the day when solar panels can generate electricity and use it at night or other times when solar panels cannot produce enough energy.
However, if you dont have a lot of appliances that work at night then solar batteries may not be as useful and you might find it easier to just stick with regular grid-based electricity instead.
If your solar panels produce more electricity than you need, solar batteries can also help you sell this extra power back to the grid. This is done through a process called net metering, and it can give you some extra income while offsetting the cost of your solar battery system.
So is solar battery storage worth getting? Well, its important to be mindful of how much power solar batteries can provide for your home before deciding whether or not solar batteries make sense.
We recommend solar battery systems for anyone, even if it is just used to provide backup power.
What Is A Solar Battery
Want to go off-grid, have a solar battery backup system or merely increase your level of self-reliance? Well, your goal will impact the type of battery system you invest in. Energy Storage Systems arent for everyone though, so here we look at the pros and cons of investing in an ESS. Luckily there are probably more pros than cons to investing in energy storage, especially when it comes to solar power. The pros vary and depend on the type of system setup. i.e. grid-tied with battery backup vs off-grid mode. This can also be referred to as AC coupled or DC coupled battery systems.

How Do I Choose The Right Solar Panel Batteries
Searching for the right solar panel battery for your needs can be a little confusing, but there are four key features to take into consideration when looking to buy a solar battery for your system.
Capacity rating The capacity rating tells you how many kilowatt hours of electricity a solar panel battery can hold. This rating represents how much electricity you have stored in your battery
The capacity rating isnt very useful on its own, and the power rating needs to be considered alongside it.
Power rating The power rating tells you how much electricity a battery can deliver to your home at any one time, measured in kilowatts. From here you can determine how many appliances you can power in your home with a solar panel battery.
When looking for a battery, note that batteries with a high capacity and low power rating make useful backup generators, as they can power a few important appliances, like a refrigerator or freezer, for a longer period of time.
Conversely, a battery with a low capacity and high power rating can power the whole house but only for a short period of time, as there is less electricity stored within the battery.
Depth of discharge This is the percentage of a solar panel battery that has been discharged in comparison to the total capacity of the battery, Most solar panel batteries will have a specific depth of discharge to maintain the health and longevity of the battery.
How Much Does A Solar Battery Cost
A solar battery typically costs £4,500, though the exact amount depends on its size, its brand, and the materials its made from.
Batteries also require little to no maintenance, so your initial outlay will probably be the last time you have to spend money on them.
Youll usually pay 10% to 20% more for a solar battery that can take you completely off-grid, which typically works out to around £5,000.

Saving On Electricity Costs
If you have opted for net metering, your utility services will provide you with credit for energy you have exported to the electrical grid. The amount of credit will depend on the amount of energy you export. It is beneficial if your utility services offer time-of-use rates to provide a rebate on electricity bills.
Since the electricity rate varies depending on the time of the day, you can opt to use the stored solar battery energy during peak usage hours and save considerably in terms of electrical bill expenses.
Efficient solar power service providers provide custom-built solutions to suit the energy requirements of households or commercial facilities. They use historical consumption data from electricity bills and then discuss the consumption habits with the clients.
They also discuss feed-in tariff potential and system size that will cover all of the relevant aspects. A quality solar provider then works out a personalized solution that allows the customers to achieve the minimum or even zero electricity bills.
Australia is prone to extreme weather conditions now and then. It can get very hot at times and most of the houses arent built for the cold nights. In any instance, electricity expenses are expected to go up as you crank up the ACs in the heat or turn on heaters in the cold.

Price Arbitrage: Using A Battery To Avoid Time
One of reasons why you might want to have a storage battery is price arbitrage. This is a fancy way of saying that you charge your battery when electricity is cheap to avoid using grid electricity when its expensive.
Many solar homeowners have a time-of-use plan that causes the price of electricity to be low during off-peak hours and expensive at peak hours. This is especially true in California, where itâs now mandatory for new home solar installations to have a TOU plan.
Peak hours occur when electricity demand is highest. This is usually the early evening on weekdays, typically from about 4 pm to 9 pm. This also happens to be the time of day when solar power generation starts to drop off, which means that if you have solar panels without a battery, youâll probably be cooking your dinner at least partly with expensive peak-hour grid electricity.
How does a battery help in this situation? On a clear day, solar power generation is greatest for a few hours on either side of noon. This period usually isnt peak hours for utilities, and because the average homeowner is also often away at work or school during this time, their solar panels may be generating excess power that is sold into the grid.
Fortunately, if your battery was recharging earlier in the day, it can now discharge that electricity to power your home. If you have enough capacity, the battery could allow you to keep your home powered without using grid electricity until after peak rates end.

Why Do You Need A Solar Battery Storage System
Pairing solar batteries with solar arrays is a relatively new practice, but an effective one. You can benefit from solar battery storage in 4 key ways:
Firstly, a solar battery stores the energy generated during sunlight hours and makes it readily available for use during non-production hours, such as at night or on cloudy days. By making use of you can essentially run your home on 100% renewable solar energy around the clock, as long as electricity demand does not exceed the supply that the battery can provide.
In addition, solar battery backup power can lower your energy costs significantly. By charging the solar battery during off-peak hours and discharging it during peak hours, you can avoid paying a lot for electricity from your utility company. The savings from this can serve towards reducing your battery system costs.
What’s more, you can sometimes earn money by selling the energy stored in your solar battery back to the electrical grid when electricity prices are at their highestif your energy provider accepts the exporting of stored energy.

Should You Get A Solar Battery
At EnergySage, we want everybody to be able to take advantage of the benefits of clean energy, and there are few technologies better suited to increase the adoption of renewable energy than energy storage. At the same time, we recognize that solar plus storage isnt always the right solution for everyone.
This section is designed to help you answer the question: Should I get storage? Well run through the main things you need to consider when deciding whether to invest in storage for your home or business.
- There are several factors to consider when deciding if a battery is right for you. You’ll need to know if your property is a good fit, if you want standalone or solar-plus-storage, and what costs look like, to name a few.
- Complex electricity rate systems like time-of-use and demand charges make solar batteries more worth it.
- Just like solar, storage costs vary by geography . Make sure to know exactly what you’re eligible for and what your true cost of storage is.
Solar Batteries And The Federal Itc
Perhaps the best case to make for buying a battery now instead of later is the federal investment tax credit . If you install a battery with your solar panel system today, you can claim up to 26 percent of those costs as a credit on your federal taxes, which means a credit of around $4,000 for the average battery system. However, the ITC will step down to 22 percent in 2023, and expire for homeowners in 2024.
Waiting too long to install a battery will mean missing out on this lucrative incentive, and potentially paying more for your battery than you would have with the credit in place.
Also, when considering incentives, keep an eye out for more than just the ITC: many states or utility companies currently have limited-time incentive programs in place to promote solar-plus-storage adoption. Popular examples of this today include:
- Self-Generation Incentive Program in California
- Energy storage tax credit in Maryland
- Long Islands storage incentive
- And more!
So before you decide whether to install a battery now or later, make sure to learn more about the current incentive opportunities in your area and the date when theyll no longer be available.
