How Do Home Solar Battery Banks Work?

Home solar battery banks allow you to become fully independent of the grid, giving you your own electricity-creating property.

Home solar battery banks allow you to become fully independent of the grid, giving you your own electricity-creating property. When storms or grid failures hit, your home will still have its lights on.

Come rain or shine, home battery banks keep your home juiced. Here’s how they work and why our are the best:

1 – Steal the Solar Power

It all begins on the roof. Those shiny solar panels absorb sunlight and use a solar inverter to convert the sun’s energy to electrical current. Magic. Then that energy gets fed throughout the home or to the home solar battery bank.

2 – Time to Feed the Home Solar Battery Banks

The electricity produced by the solar panels then powers everything in your home. From the TV to the lights, the power goes to those appliances first.

But on sunny days or low energy consumption days, there’s plenty of excess power. That electricity goes to the home solar battery banks!

Here, batteries charge up by using inverters and store electricity for future use. The speed of charging depends on the amount of solar energy being produced and the current demand in the home.

Without a battery, that extra electricity would head back to the grid (if connected). That process is called net metering and can actually earn you money, but for many people, that isn’t as appealing as having those game-changing home solar battery banks!

3 – Converting the Energy

Time to get slightly geeky. All homes run on AC (alternating current). That’s the power you get from your wall outlets. But batteries require DC (direct current to charge) – that’s why your laptop has that big box on it, or why your phone charger has a big adapter at the end.

Solar batteries work the same. They require DC. Using solar inverters, they convert AC into DC to charge and then back to AC to power the home.

Some modern home solar battery banks, such as Tesla Powerwalls, use AC. That can make them versatile for any solar power system but make them susceptible to storms and harsh conditions. DC batteries also have higher efficiency.

4 – Deploy the Battery!

Once that home solar battery bank is nicely charged up, it sits there until it’s time to use it.

There are various reasons for calling up your home solar battery bank’s extra power.

Firstly, a power outage. If the grid goes down, the battery system will kick in and immediately provide power to the home. Your fridge, AC, TV, internet and lights will all keep running.

Secondly, home solar battery banks can be used to reduce your energy bill. If your utility company uses a ‘time-of-use’ (TOU) rate plan, then you may find that certain periods of the day are more expensive than others.

If you’ve got a solar battery bank, though, you can use it during those peak utility charge periods to make savings!

Finally, batteries can be used for homes independent of the grid. So if the sun has been hidden for too long and your home is low on fresh solar energy, you can rely on your home solar battery banks to kick in and save the day.

The Science Behind Home Solar Battery Banks

Ok, you’ve read this far, so let’s get into the details. Now you know how a home solar battery bank works, let’s look at the science behind it.

Most modern home solar battery banks use a lithium-ion battery. These are seen in many appliances, from your cell phone to cars.

They operate by moving lithium ions through an electrolyte located inside the battery. Ions are particles that have either gained or lost an electron, so when they move from an anode to a cathode within the battery, free electrons are produced.

These free electrons build up, charging the battery and storing electricity. When it’s time to discharge the electricity, the flow is reversed.

You can take off your lab coat now.

How Much Solar Do I Need?

How much solar do I need? How many solar panels do I need? These are common questions for anyone looking to install solar power in Florida.

How much solar do I need? How many solar panels do I need? These are common questions for anyone looking to install solar power in Florida. The answer lies in your current energy usage. So, dig out your recent energy bills. Here’s how to work out how much solar you need:

Use Our Solar System Sizer Tool

We’ve got you covered with a handy tool that will calculate how much solar you need. Here’s how it works:

Step 1

  • Get out your energy bills.
  • Take note of the highest, middle and the lowest daily kWh usage. Or, if you have 12 months of bills to view, you can take the highest, middle, and lowest monthly power bills and use those instead. (If you don’t have this information available, your energy company should be happy to provide it to you).

Step 2

  • Use our calculator to calculate your average kWh usage or monthly cost.

Step 3

  • View our chart on our solar sizer calculator to see how much solar you need.

Example Calculation – How Much Can I save?

Here’s a quick example of how much you could save. We’ve used our system size calculator:

  • Highest daily kWh usage: 53 kWh
  • Middle daily kWh usage: 42 kWh
  • Lowest kWh usage: 28 kWh
  • Calculated Annual Kilowatt Usage: 14,965

Using this calculation, our suggested solar system size would be an 11.59 kW system (Florida Power Company’s top seller). With an estimated production of 17,458 kWh per year and 1,455 kWh per month, here are the savings we could make: $2,254 yr / $187.83 a month!

How Many Solar Panels Do I Need?

Don’t worry; we’ll take care of calculating how many solar panels you need based on the optimal setup for your roof, location and how much you need based on your kWh demands.

Why Install Solar Panels?

So, you’ve worked out much solar energy you need. But, what next? It’s time to install your solar system. Here’s why:

Solar PV Reduces Electric Bills

As you’ve seen in our calculations, you’re going to save a lot through energy bill reductions. Using our example, over 20 years, you would save over $45,000! Regardless of your solar system size, you’ll save money. That’s a fact.

It’s a tested and proven method. Take those sun rays and convert them to electricity on your own property. Power your lights, appliances, TVs, computers and more – with your very own solar panels.

Net Metering

Better still, you can get money back through net metering. Net metering is when you feed your excess solar power generation back into the grid. You get rewarded for it by your energy company. Even more savings!

Solar PV is Better than Hybrid Heaters

As the price of solar installations in Florida has dropped in recent years, the benefits of heating your water with solar electricity have gone up. Water heaters are notoriously energy thirsty and a primary cause of high electricity bills.

With solar panels, you’ll be powering your water heater with consistent free energy—no need to worry about those long showers as much anymore. If you’re producing enough electricity, you can have them as long as you want – because you’re not paying bills!

Sunlight Hours for Your Location in Florida:

Worried about whether you’ll get enough sunlight hitting your solar panels in Florida? Fear not, it’s called the ‘sunshine state’ for a reason:

  • January: 6.9 hours
  • February: 8.2 hours
  • March: 8.4 hours
  • April: 9.3 hours
  • May: 10.9 hours
  • June: 10.7 hours
  • July: 10.8 hours
  • August: 9.5 hours
  • September: 8.9 hours
  • October: 7.6 hours
  • November: 6.5 hours
  • December: 6.3 hours

Average daylight hours source.

Average Appliance kWh Consumption

If you want to go deeper into how much solar you need, you can analyze your appliances. On average, annual appliance energy consumption looks like this:

  • Refrigerator: 600 kWh
  • Air Conditioning Unit: 215 kWh
  • Central Air Conditioning:1,000 kWh
  • Electric Vehicle: 3,000 kWh
  • Heated Swimming Pool: 2,500 kWh
  • Hot Tub (outdoor): 3,300 kWh
  • LED TV: 432 kWh
  • Desktop computer: 194 kWh
  • Laptop: 150 kWh

What Affects Solar Panel Efficiency?

Many factors come into play here—for instance, the angle of your roof or shade from nearby trees. At Florida Power Services, we always design solar systems to provide optimal year-round energy production.

The quality of the panels also matters. Some companies use cheaper materials than we do, which results in poor absorption of those sun rays. Be wary of entire solar roofs made of solar tiles, too; their aesthetic qualities come at the price of less being efficient than regular solar panels.

What About Battery Size?

Solar batteries capture the unused solar power generated during the day, saving it for when you need it at night or during low-sunlight days. When planning battery setup, we consider:

  • Your average kWh demands.
  • How long you’ll need the battery to provide power for during the night or cloudy days.
  • The best return on investment for your plans, so you can begin to make a profit ASAP.

Grid or Off-Grid?

A significant factor in decking your solar power system setup and size is whether you want to be connected to the electricity grid or not. If you’re grid-tied, you have the space to rely on the grid’s energy at all times, including during the night.

But if you go off-grid, you need to be sure you’ll have enough energy throughout the day – so usually, more space is given for extra kWh demands.

Off-grid solar systems are completely disconnected from the main grid. They’re often used by people looking to live in rural areas with a 360 green vision. Solar batteries are a must in off-grid solar systems and usually require more solar capacity than grid-tied systems.

Act Now to Save Thousands of Dollars in 2021!

How to Size Your Solar Battery System for 24/7 Day and Night Energy

If you’re looking to install a solar with battery backup system in Florida, sizing it correctly is essential to meet your performance expectations. If you underestimate the needed kWh to power your loads through the night and you could wake up sweating in the dark – you’d rather have more battery capacity than not enough. Another key parameter to calculate is the AC output (or Amps) needed when your solar system functions in “Standalone Mode”, all batteries have different outputs with/without the grid. Proper sizing is step one of our solar consultation, next is a quality design using reputable equipment, and finally the best way to purchase.

The question many new solar owners ask, “What size solar battery system do I need?”. Here’s the answer:

What Size Solar Battery Do I Need?

The best way to get all your questions answered is to schedule a consultation, during the consultation we will evaluate your usage and match a custom solar battery solution to your home.

Taking into consideration weather conditions, temperature and peak power demand are 3 important factors we account for in our custom solar battery hybrid systems. You need enough runtime in your battery bank to power your loads through low light conditions/at night and also proper AC Output to the loads. Undersizing your AC Output may cause your battery inverter to cycle on overload and/or trigger an overcurrent issue resulting in loss of power with possible damage to your equipment. A lot of “out of the box batteries” have output limitations that fail to meet the demand required when the battery cycles. Our consultation evaluates your needs sizing your solar and battery bank to provide the proper runtime matched to amps to power your loads when you need them the most.

Step One: Size the Solar

The solar array needs to be large enough to offset your utility usage and charge the battery bank, upsizing the solar a little is recommended for optimal performance in low light conditions. We always say “you’d rather have more than not enough”.

Check Your Energy Bill

If your home is grid-tied, finding your daily kWh usage is pretty simple and can be done using a power bill and our sizing tool. Sizing your solar array by kWh is much more accurate than going off the dollar amount of the monthly bill.

Use Our Solar System Sizing Tool

Our Solar System Sizing Tool
Off Grid Solar

Off-grid location? Our engineers can design a solar micro grid when utility power is too expensive or non existent, there are many variables to consider when looking at these types of systems and may be costs involved to accurately size and quote. We have extensive experience working on the outlying islands surrounding Florida with dozens of our solar offgrid designs providing power to homes in some of the most beautiful remote locations around. When you need reliable solar power make sure you’re dealing with an experienced contractor with a NABCEP certification and Solar license.

Step Two: Calculate the Battery Capacity You Need

Sizing the needed kWh in your battery bank is easy with our Battery Sizing Tool!
Battery Sizing Tool
There are 3 main parameters you’ll want to carefully compare when you’re shopping solar with battery backup;

  • kWh = Runtime or energy stored in the battery.
  • AC Output = Amps or peak power needed to start and run loads.
  • D.O.D. = Depth Of Discharge which is the usable energy in the battery bank
BATTERY BANKS AC Output
(Peak & Continuous)
D.O.D.
(Depth Of Discharge)
16 kWh 66 A @240V (10 Sec) | 33A @ 240V 100%
22 kWh 66 A @240V (10 Sec) | 33A @ 240V 100%
32 kWh 132 A @240V (10 Sec) | 66A @ 240V 100%
48 kWh 156 A @240V (60 Sec) | 84.99A @ 240V 100%

How Many Kwh Do I Need in My Battery Bank?

More than less! The kWh in a battery bank are used at night or in lowlight conditions when the solar production may not be enough to power the loads. An easy way to calculate this if you have a utility company is take your peak kWh usage and calculate 66%.

AC Output?

This parameter is often overlooked by off the shelf solutions and is just as important as the kWh in your bank. The peak power is the battery inverters ability to start and run your loads. Since all batteries are DC voltage (24-400V) we need to invert to usable AC voltage (120V-240V) to be compatible with the US grid and/or power loads. Our consultation is the best way to be sure your AC Output on your solar with battery backup is sized properly.

D.O.D. (Depth of Discharge)?

The depth of discharge indicates at what level the battery can discharge before recharging. With today’s lithium battery chemistry this range is usually between 80-100%. Some of the biggest names in batteries are on the lower end of this number while our custom battery banks have 100% D.O.D giving you more usable energy when you need it.

Safety Buffer (Days of Autonomy)

We always suggest making a safety buffer. By adding some reserve storage space, you’ll gain access to energy during cloudy days, the night, power outages, storms and other situations where your panels are struggling to generate enough energy.

You wouldn’t drive your car for hours with the gas light on, so why is your home any different?

Decide how many days of autonomy you want your solar system to be able to provide. Between one and two is usually wise. Don’t sell yourself short!

Can I Add a Battery to My Existing Solar System in Florida?

Yes! We can design an AC Coupled battery bank to retrofit your existing grid tied solar with battery backup. Our grid tied battery backup will cycle when the grid fails keeping your loads on through unexpected power interruptions. Here at Florida Power Services “The Solar Power Company” we make adding solar batteries to existing solar panels easy using no money out of pocket loans with rates between .99% – 2.99%.

  • No more paranoia about running out of electricity!
  • Full power, day and night!
  • Protection for storms, cloudy days and grid blackouts.
  • Low monthly payments!

How Long Will Solar With Batteries Last?

Solar battery technology has come a long way from Lead Acid batteries with short 3-4 year life expectancy and low depth of discharge (around 50%) to powerful Lithium Ion batteries with life expectancies of 20+ years and 100% depth of discharge. Lithium Ion batteries are extremely durable and require no maintenance giving them some of the longest lifespans of the batteries commercially available today.

Can Solar Battery Back-Ups Save Money?

Solar battery banks vs generators do save money in Florida! After factoring in the cost of fuel, maintenance, and life expectancy of a generator the solar with battery backup lasts twice as long with virtually no maintenance or costs after installed. You’ll also be significantly boosting your property value, not to mention solar with battery backup makes your home more attractive to prospective buyers should you decide to sell in the future.

2020 Is the Time to Act to Save Money!

As 2020 heads towards its conclusion, there is still time to save thousands of dollars. But act fast! After this year, you’ll no longer be able to get the massive 26% reductions through Federal Tax Credits.

For example, if your solar power installation in Florida costs $38,000, you can receive Solar Tax Credits of $9,880 in 2020. Don’t miss out on this great opportunity, we have limited installation availability due to demand. Contact us now for a solar consultation and beat the deadline.

FAQS About Florida Solar Battery Banks

Solar battery banks can ensure your home or business functions normally in the event of a hurricane, utility outage or grid failure. Whether you’re looking to add battery storage to your existing Florida solar system or you’re a newcomer to self-sustainability looking for guaranteed power when the grid fails – we’ve got you covered.

What is a Solar Battery Bank?

A solar system equipped with a backup battery provides you with the ability to use electricity even when the grid is down. With a solar battery storage and backup inverter, your home or business won’t suffer a blackout during hurricane seasons or any other cause of power loss.

Frequently Asked Questions about Solar Battery Storage

Now let’s field some questions from our followers in the Florida area, who are shopping for Florida Solar Battery Banks.

Will my solar system power my home or business when the grid fails?

~Janice in Clearwater

A: Only if you have a battery bank in your system. Without that, solar systems shut down along with the grid to avoid back feeding power and potentially shocking a utility worker. So, solar battery storage is what you need! It must fit your existing system properly.

I had another company quote me and they told me one battery was enough to run my entire house in an outage, I’m wondering if this is true?

~Jimmy, S. Tampa

A: Great question, Jimmy. The two biggest variables you need to consider when shopping for a solar battery bank systems are:

1. How many kWh a day does your home/business consume mid-summer?

  • Example = July bill 1,200 kWh / 31 = Daily usage 38.7 kWh
  • This would bring your recommended battery bank size to roughly 40 kWh at 95% Depth Of Discharge.
  • This would 4 – 10 kWh Enphase Encharge Batteries

2. What is the peak amp draw of the loads?

  • This can be determined with an amp clamp at your load center or if you have an energy monitor like Sense.
  • You’ll be able to pull up this data online.
  • Match the peak amp draw to the peak AC output of the battery bank.
  • In this example, the peak output of 4 – 10 kWh Charges is 95A for 10 seconds.

How do I make sure my solar contractor is reputable and experienced?

~Bill in St Petersburg

A popular question here and a very important one given the failure rate of Florida solar companies. We’ve been in the industry long enough to know the obvious signs of a legit company and those that let you down. Here’s what we suggest:

  • Look up the company on SunBiz.org, check how long they’ve been in business.
  • Confirm the owner of the business is also the license holder, you can check the license number on the DBPR website.
  • There’s always the Better Business Bureau, look for complaints and ratings.
  • See what people are saying on Google reviews and social media.
  • Check certifications, look for the Florida solar license “CV” and or NABCEP certification – it should be listed on their website. Don’t use uncertified companies.
  • Be wary of other home improvements being bundled into the solar package with unquantifiable savings promises.
  • Check their experience level. At least 10 years of experience is needed to prove they’re not going to collapse at any moment like Brevard Solar did.

How long can Solar Battery Bank systems run when the grid fails?

~Richard in Bradenton

A properly sized solar battery bank system, with adequate sunlight and a healthy life expectancy, should keep you running with independent electricity for 10-15 years. That should be more than enough to keep you safe during any disastrous events.

Can a Solar Battery Bank be installed anywhere on my property?

~Tom in Palm Harbor

Solar battery banks can be installed inside and outside. Still, they’re quite large and require some decision making for practicality, protection and aesthetics. We can help advise you with this.

Can I add solar battery storage to my existing solar system?

~Lucy in East Tampa

Yes, we frequently add solar battery banks to existing solar systems.

Why would I need solar battery storage?

~Phoebe in Riverview

There are three answers to this question – a reduced energy bill, a reduced carbon footprint and protection for electricity outages.

Solar battery storage allows you to use the sun’s light even at night, as it’s been stored up in the battery all day, waiting to be used for FREE. That results in a far cheaper energy bill and far less fossil fuel energy

If the hurricane season hits badly and destroys power lines, a solar battery bank will keep your lights on, your food fresh and your family safe.

In terms of long term threats, sadly, we have more than a global pandemic to prepare for – we have the climate crisis. That is likely to cripple the fossil fuel industry and cause electricity prices to skyrocket, or even bring the nation’s energy to a grinding halt. With a solar battery bank, you’re protecting yourself from these scenarios by ensuring you have power at all times.

Is it true that after 2020, Florida solar installation costs will rise?

~Pete in Citrus Park

Yes! In 2020, you can save 26% on solar installation costs thanks to Solar Tax credits. However, over the next two years that figure will hit 0% (20% in 2021, 0% in 2022). In fact, we might be looking at the cheapest price for solar installation for decades. 2020 is the time to act!

Will a solar battery work on a cloudy day?

~Daniel in Highpoint

Yes! In fact, this is when they can be most useful. Without a solar battery storage you could be using grid energy on cloudy days. But with a battery, you can get a decent amount of energy to reduce your bills and carbon footprint.
