Using Solar Panel To Charge a 12 Volt 100ah Battery Standard Size Solar Panel is 58 inches by 27 inches, 2 Solar Panel for 150 watts 12 Volt each for 5 sunshine light hour takes to recharge 100ah 12 volt Battery. Generally, a fully discharged 12 Volt 100ah battery needs 1200 watts of energy to be 100% recharged. So the calculation is 1200 / 300 = 4 hours of sunlight. 15% less efficiency, about 5 hour’s sunlight.

What is Needed for a Solar System?

  1. Connecting Cables, put the solar system, charger controller, battery together.
  2. Mounting Sets, you’ll need them to install the panel in full sunshine place and angle.
  3. Power Inverter (optional), convert the DC to AC power for AC devices.
  4. Solar Panel(s), connecting more by series or parallel to urge 12v, 24v or 200w 300w…etc.

How to Charge 12 volt Battery With Solar Panel?

3 Step to Charge Battery With Solar Panel

Wiring Sequence: Solar Panel to Charge Controller (to DC Load) to Battery to Inverter to AC Load.
Step 1: Connect the battery cable to the charge controller.
Step 2: Check the charge controller.
Step 3: Connect the solar panel to the charge controller.
Note: Solar Panel Converting DC Electricity, for Charge or Run AC Device Use inverter.

What voltage do solar panels produce at maximum sunlight to charge an acid battery connected by a charge controller?

Typical maximum system voltage in a photovoltaic solar panel gives about 18.5 to 20.8 volts peak output (Array cell voltage 0.58v). This volt comes from a standard photovoltaic array system connected with 32 or 36 individual solar cells. This is enough to charge a standard 12v acid or lithium battery.

The technical specifications of the modules indicate a nominal voltage of 12V, but for a regular operation of the battery charger required about 16-17V.

Voltage at the operating point of the solar module with 36 elements to gather 1000 W / m2 and a temperature of 25°With about 17 In.

When the temperature rises, the voltage decreases, and when it decreases, it increases.

Modules with 72 elements have a rated voltage of 24V, at the point of maximum power — about 34V Suitable for charging 24V AB via PWM controller.

Modules with 60 or 48 elements are modules for MPPT controllers or network photovoltaic inverters (which always have an MPPT controller).

How many solar panels does it take to charge a 100ah battery?

 In general calculation, a fully discharged 100 amp hour battery can be recharged by a 300w solar panel or 3 X 100w parallel connected solar panel in a full sunlight day (5 hours).

In physical working mode, any size of solar panel will recharge your battery when the photovoltaic cells only have to be at higher voltage than your battery.

It all depends on how fast you want the battery to recharge and what load is placed upon it.

The Calculation is:

100 Ah/5-hrs = 20A

(this means charging your battery at 12V and 20A will take 5-hrs to fully charge a 100Ah battery)

20A x 12V = 240 watts

So, I suggest you get a 300W solar panel or higher to do this if you want to recover in a day.

I also suggest you get a MPPT solar charge controller capable of at least 300W of input power (usually 48V) and output 13.8V to charge the battery (if it’s lead acid).

When choosing a solar charger, it is important to pay attention to the price, the quality and the desired uses. The material of the solar modules is of less importance in this case.

The higher the output of the solar charger, the faster your mobile devices charge, because the USB ports have a higher capacity to meet the power demands of each connected device.

There are two key aspects to consider:
Which mobile devices will you charge with the solar charger?

That’s the first question you should ask yourself: Which and how many mobile devices will I charge with my solar charger?

The question is important because the prices of the solar charger vary greatly depending on the power provided.

If you want to charge two or three mobile devices with your solar charger at the same time, you’ll need more power. If you only want to use the solar charger from time to time for a mobile device, a solar charger with 15-20W is sufficient.
How do the sunbeams hit the solar modules?

Suppose it is a sunny day. For good performance and faster charging of your mobile device, the solar modules must be aligned so that the sun’s rays are perpendicular to the solar collectors.

solar charging sequence

How long to Charge 12v Battery with Solar Panel

Without knowing the charging state, its impossible to tell you what it takes to charge a 12v battery with a particular solar charger.

How fast a solar panel could charge a battery depends on its current sourcing ability also.

So, we are assuming a fixed charging efficiency of a solar charger so determine what it takes to complete the charging. So,

Our solar charger offers 85% charging efficiency. So, panel’s output power will be 85w if it’s putting out 100w. If our charger output is 12v, its average output current will be,

85W/12V = 7.083A.

So, to charge a 200A-hr battery the calculation would take,

=200A-hr/7.083A

=28 hrs.

That is means a wholly discharged battery would take this time in direct sunlight to fully charge up.

This may be possible in some countries around the globe but initially not practical for most of the places. It’s an optimistic calculation that assumes proper panel ventilation and deducts few other inefficiencies, however, its decent beginner’s point calculation.

How to Charge a 12V Battery with a Solar Panel?

 

To charge a battery solar energy is a free and easy option to get. It requires a few types of equipment which are safe, easy to understand and affordable.

You need items like battery, converter and of course, a solar panel. Many local hardware shops and online stores serve thousand of brand items at different price point including warranty, customer service, etc.

A decent size quality solar panel for 12v batteries could be mount in your yard, near a cabin/ tent, on the boat and anywhere you need with direct sunlight. Here is a simple discussion about what you required to build a solar power system to charge a 12v battery.

Solar Panel Battery Charger: 25 yrs Power Output

A Solar Panel Battery Charger is a device contains a Photovoltaic Solar Panels, Solar Charge Controller and a Solar Battery, generally portable, that allows the photovoltaic solar energy to be converted into electrical energy that can be used by many electrical devices.

1. Solar Panel

Choose a solar panel that offers the highest amount of features and power at your budget point. Also, make sure its easy to carry and operate single-handedly.

But that does not mean you have to get a flimsy one that neither has stability nor quality. Other than that your panel should be well rugged and able to produce more power even in low light condition.

You can choose a portable solar panel instead of a fixed one. Portable solar panels are best for transportation. But the power capacity and durability is exceptionally low. However, portable solar panels are cheap and flexible to use.

Solar panels that offer 12 volts are more or less inexpensive for better performance you can have 16v panel to get more faster performance.

You can buy a customized solar panel with the help of an expert also. This type of panels gives scopes to add or remove multiple panels and other items to get 100% service that you ask for, well in most cases.

2. Charge Controller

In current days. Most of the solar panel especially the portable panels comes with a charge controller. If your system does not come with a charge controller, then you should get one.

It’s for added performance and protection. This affordable piece of tool automatically disconnects the battery from the solar panel when it’s fully charged. Besides, the unit with max energy power point tracking (MPPT) circuit maximizes the energy from the system.

Remember one thing, get a controller that can handle more than peak amount of energy from the panel. If there is more than one panel make sure these can deal with the total amount of power from the cells.

3. Solar Battery

There are different size and capacity of batteries available, but hence we are talking to 12v let’s stick on that. 12v batteries are useful for numerous charge and recharge cycle. A deep period 12v battery is designed to be discharged fully and later replenished without changing the electrolytes or internal plates.

If you are thinking of using car batteries (except the deep cycle one) with a solar panel, then skip that plan.

Typical car batteries are not made for continuous drain and soon after it may fall to hold any charge correctly. So, get a specific type of battery that could handle constant charge and discharge and be alright.

4. Solar Inverter

A battery’s DC voltage is 12, but maximum household gadgets run at 120 volts of AC. If you add an inverter like as the cigarette lighter of a car, the stored power in a battery will help to charge any household devices.

Just look for some little things before getting an inverter. Like, the current flow provided by an inverter should be accurate to accommodate the load. Also, select one with multiple sockets.

5. Solar tracker

A solar tracker is a maximizer. It works to turn a solar panel to the sun, so it gets full light always.

We all know its nearly impossible in some places to get 100% sunlight for at least 6 hours constant. Especially if you live in a location near mountain, jungle or anywhere, whither sunlight obstacles by shades of something.

So, increase the effectiveness by getting a solar tracker and it’s inexpensive also.

A calculation before having the right solar charger

An hour of sunshine is like one hour of music or 25 mins of talk. A battery of solar panel last years and could charge many gadgets like iPhone, game, Bluetooth, digital cameras, etc. A solar charger is relatively light and easy to move around or transport for travel purpose.

Fixed units that need to mount are slightly uncomfortable to shift due to its extensive body in most cases.

The rule for calculating the average charging time is,

Divide the amp/hour rating of the battery with charger rating (amp) and then add about 10% for the additional time to top off the battery.

Suppose you have a regular size of the auto battery and its about 30 amp hours. To calculate the time, a 12 watts solar charger, you need,

  1. Count the Ampere per hour of the charger: 12 Watts /12 Volts = 1 Amp.
  2. Count the division: 30 amp hours / 1 ampers= 30 Hours of direct sunlight.
  3. Add 10%: 3 hours.

Chargers in between 12- 15 watt is good for vehicles like cars, boats, RV’s, ATV’s including electric fences.

If you need to charge laptop and camcorders the 7 watts are good. For smaller cameras, cell phones, and smartphones 2 watts are perfect to have.

There is another formula to help describe how the solar energy works? The solar energy’s output is denoted by watts. It can be understood by multiplying the voltage by amperage.

So the calculation would be- Voltages X Amperes X Wattage

Assume, a 7-volt 30-watt solar panel with 10 by 22 inches size has a voltage around 7.65 and amp 2.75. The amount of wattage determines by how much an electronic device or device can turn out.

How Many Time Does the Solar Charge Give You?

The answer to the question is the size and number of the solar panels and the setup installed in your house or on the location you want to.

The weather condition of areas also a significant factor for solar charge.

During a rainy day, dark winter days or in snowfall can affect the actual capacity of a solar panel like energy absorbance and production. Also, the settings (wire, socket, etc.) depend on providing current flow to the battery good or bad manner.

The power radiation from the sun in mid-afternoon is generally at its peak point comparison to the early morning and late afternoon sunshine.

If the overall condition is excellent. Your solar panels could give the best performances if you live in a place with sunlight all year round. But some factors like blocking shadows from nearby things, unfit mounting of the solar system can deduct the energy output though.

Figuring the numbers of hours a solar charger depends on the mentioned factors explained earlier. Assume a 50 watts of solar panel in your house can receive min 6 hours of maximum sunlight and can generate 300 watts hours of power in a one-day average.

But it the solar panel gets 3 hours of daylight, then it will able to make 150 watts of power per day only.

How Is Big of a Solar Panel Needed to Charge a Deep Cycle 12 volt Battery?

Charging a 12 volt deep cycle battery its essential to consider factors like design, features and the cycle system, means the makeup of the deep cycle battery including the size.

This battery is the standard battery often use in cars, RV’s, troller boats, etc. this type of cell is designed to charge and recharged numerous times. They are rated according to amp hours.

  1. HS Hi there- I m installing a 36000BTU multi split inverter air condition system in my home. The specs I see from on the ac unit is that it will operate at 2600W at 220VAC. I m hoping to be able to run this unit completely off grid as energy prices are quite high. In my area, I get approximately 6 to 8 hours of good sunlight. I expect that my air condition will be in operation Mon to Fri for 6 hours per day and on Saturday and Sunday 14 hours per day for a total of 58 hours per week. I m looking to use deep cycle batteries which are rated at 1h. My hope is to use solar to recharge the batteries. My question My question is- how many batteries would I need to run this ac unit and how many solar panels would I need as well? Can you recommend which solar panels I should use? Thanks in advance.

  2. Dear friend!
    I’m new to this thing. I would like to know If it is possible to include a solar panels in a system which I already have. Vectron inverter and a battery 220Ah

    I want to run an incubator machine 220v 400watt.

    My idea is that, when there is a shortage of main power(electricity) in the area I can use this kind of power backup. If it is short time shortage I use inverter charger and battery
    If it’s long time shortage, I use solar panel.

    If possible, I would like to know which size and power of that panel is required
