Which Is Better Pwm Or Mppt
There are two main types of solar charge controller Pulse Width Modulation and Maximum Power Point Tracking .
The PWM is a dumb device and simply compares the voltage between the panel and the battery, and sets the output current by chopping up the output to achieve an average.
Its quite inefficient, but adequate for small applications where efficiency is not the prime concern.
Maximum power can only be drawn from a solar panel when the load resistance matches the panels Characteristic Resistance. This is what the MPPT controller does.
An MPPT charge controller adjusts its own internal resistance until the panels voltage and current are at optimum levels. MPPT type charge controllers are up to 40% more efficient than PWM.

Cloudy days likewise will cause your battery to charge more slowly than sunny days. This is because clouds filter out most of the UV light from sunlight before it even reaches your solar panel. While youre still collecting sunlight, the photons from a cloudy day dont have as much energy and therefore produce less electricity and heat in your 100W solar panel.

What Size Solar Panel For A 12v Battery
After calculating the battery capacity and its DOD limit which gives us the wattage capacity of the battery so now lets calculate what size of solar panel will do the job
Lets assume that youre using a 100Ah lithium battery so you need 1200 watts of total power to fully recharge the battery from 0-100%
Now, what size solar panel youll need to charge your battery in a single day? Use this formula to calculate the size of the solar panel for your 12v battery
+ 20% = 288 watts
So a 12v 300W solar panel will fully charge the 100Ah battery from 0-100% in 5 hours under ideal sunlight conditions or a 150W solar panel in 10 hours
use this website to see the average solar sun hours in your city. I live in Florida so here we receive about 5.8 peak sun hours.
This estimated time is based on if your battery is on rest mode means no appliances are connected to the battery while charging. But if youre running the appliance with a battery while charging then add up the watts of the appliance into the solar wattage required then calculate the size of the solar panel
What Is An Amp Hour Rating
If you are in the market for a new 12V battery, you will find an amp hour or an Ah rating on almost all of them. And this rating is one of the most important things to check since it essentially tells you about the capacity of a given battery. It tells you about the amperage that can be supplied within an hour from your 12V battery.
Apart from getting an idea of the capacity of your batteries, this rating can also be useful to get an idea of the amount of time needed to fully charge your 12V battery using your solar panel as you will see later on in this guide.

How To Set Up Your Solar Energy Station
Setting up your solar panel battery charging station isnt too difficult. Just connect the battery to the solar panel and set up the solar panel as usual.
Connect the Battery to the Panel
To begin, you need to connect your solar panel to a regulator. After that, connect the regulator to the battery.
Most of the time, there should be instructions about how to do this. However, if you are hesitant, you can contact professionals in your area who can hook up the system for you or give you pointers.
Solar Panel Placement
You must place the solar panel in a way to maximize sunlight exposure. For example, the panel should be placed at a 45-degree angle directly up at the sunlight on a flat surface in an ideal world.
Your roof will be the best option simply because it comes with fewer obstructions. However, if your roof is not strong enough to hold the solar panels, you can place solar panels on the ground, assuming that trees and other items dont cast shade over them.
If you do not have an area suitable for 45-degree angling, that is OK. Your solar panels will still produce energy, but they wont be as efficient.
Continue to hook the solar panels up as normal.
How Long Does It Take To Charge A 12v Battery With A Solar Panel
How long your battery charge takes to fill up will depend on many factors. For example, the efficiency of your solar system, quality of the battery, and sunlight exposure all affect charging time.
In the case that your battery has the same amp-hour rating as the amps produced by your solar system, it will typically take between five to eight hours to charge a totally drained battery to full capacity. Of course, this is assuming the weather out is an average sunny day.
If it is a sunny day out, the charging time will be on the lower end of this estimate, but rainy days result in a longer charging period. Old or inefficient items take longer to charge as well.

Connect The 12v Battery To The Charge Controller
Insert the stripped end of the negative battery cable into the negative battery terminal on the charge controller. Screw the terminal shut with a screwdriver. Repeat the process for the positive battery cable.
Connect the ring terminal on the negative battery cable to the negative terminal on the 12V battery. Repeat the process for the positive battery cable.
Your charge controller should turn on to indicate the battery and charge controller are properly connected. Mine has a battery indicator light that turned on.
Now you need to program your charge controller for your battery type. This lets the charge controller know which voltage to charge the battery to.
Consult your instruction manual for how to do this. In this example, Im using a sealed lead acid battery, so I programmed my charge controller for that battery type.

What Size Of Solar Panels Would You Need To Charge A 12v Battery
Now that you understand what type of battery you should be using with a solar power system, we can look into what sort of solar panels you will need and how long those panels would take to charge your battery.
The truth is, as long as you are using 12V solar panels, you can use any style of solar panels to charge a 12V battery however, it is not quite as simple as connecting your solar panels directly to your battery. For starters, you will need a charge controller, which is a device that regulates the flow of electricity from the power source, meaning the solar panels, to the battery. These devices make sure the battery does not overcharge, which can lead to permanent damage.
In most cases, you will also need to connect a power inverter, which will convert the DC power your solar panels generate into AC power, which is what most appliances and electronic devices require.
To connect everything together, you will need to use the appropriate types of cables and connectors. For more information, consider taking a look at our Solar Panel Connectors Guide, which will tell you everything you need to know about using solar panels connectors and extension wires.

How Many Watt Solar Panel To Charge A Deep Cycle Battery
Answering this question is hard, Id love to just through my hands up and declare it depends and leave it at that. But if I did that you would hate me, so lets see how to calculate the panel size.
Generally, the size of a solar panel to charge a battery is calculated using this simple formula:
For instance, lets assume we live in California where we get around 5.5 hours of peak sun hours per day and we have a 12 volt, 100 Ah battery that we need to charge using a solar panel.
Then how many solar panels to charge a 12 volt battery would be:
In other words, you need at least two 100-watt and one 20-watt solar panels to fully charge this 100Ah deep charge battery.
Thats all to it, right? I just need to buy those solar panels, connect them to my battery, and enjoy the off grid living.
Well, if you stopped reading and went right away to buy those three solar panels, then you will be wasting your money.
This is because all batteries including lithium iron phosphate batteries and car batteries have something called depth of discharge, which is simply the maximum amount of energy you can safely drain from the battery without risking permanently damaging it and reducing its lifespan.
Most high quality deep cycle batteries have around 80% DOD. This means that you should treat your 100Ah battery like an 80Ah one, as you dont want the charge to go below 20%, so keep that in mind when hunting for a new battery.
