What We Didnt Love

Our Verdict

What Size Solar Panel Will Charge A 12v Battery

Technically, all you need to charge a 12v battery is a solar panel with a 12v rating. This can be any sized solar panel, although the bigger it is the quicker your battery will charge.

Anything under 510 watts is not enough, though, as these will only trickle charge your battery very slowly. In general, 12v panels are only available up to a rating of around 200-watts, though, and from there up they are usually 24v or 48v.

There are various sizes of 12v batteries available, 100ah being the most common. For this reason, the amp hour rating of the 12v battery you have and how quickly you want it to fully charge will determine what size solar panel you need.

Different Types Of Solar Batteries

Learn which kind of battery is used for solar panels.

Lead Acid

For several years, lead-acid batteries have been used as a reliable energy supply for off-grid areas. They are typically deep-cycle and inexpensive. Lead-acid batteries are attributed to high power and discharge current but low energy. They take long to charge completely up to 14 hours.

These batteries must be disposed of correctly or they can be an issue to the environment due to their highly toxic nature.

Two types of lead-acid that are commonly used for solar panels: flooded and valve-regulated lead-acid batteries.

The flooded lead battery is a dependable option but requires watering and proper ventilation to function. The VRLA, which is equipped with valves for off-gassing regulation, comes as two types, gel and absorbed glass mat . These are suitable for cold and warm temperatures respectively. Although the VRLA batteries give enough flexibility for installation, their sensitivity to temperature may however pose a challenge to people looking for a permanent alternative to their grid supply.


Lithium-ion batteries have become a more popular choice for solar systems all over the world. The development of this type of battery has a lot to do with its application in the electric car industry. Its prismatic form allows for ventilation and benefits use in solar systems.

Battery Size/usable Storage Capacity

A batterys capacity is the amount of electricity that a battery is able to store and supply to your home. While power is expressed in kW, battery size is expressed in kilowatt-hours , which is power multiplied by time. As a result, a batterys storage capacity tells you how long your battery can power parts of your home. Be sure to look for the usable capacity of a battery, as that number represents the amount of stored electricity that you can actually access in a battery.

Since electricity usage is power multiplied by time, if you are using more power, then youll run out of stored electricity faster. Conversely, if youre only using your battery to backup a few appliances with relatively small power consumption, you can keep them running for a longer amount of time. This makes the size of a battery slightly misleading, because the length of time a battery’s charge will last is directly influenced by how much power it’s outputting.

Think about the example above of the difference between a light bulb and an AC unit. If you have a 5 kW, 10 kWh battery, you can only run your AC unit for two hours . However, that same battery would be able to keep 20 lightbulbs on for 2 full days .

What Is The Lifespan Of A Solar Battery

Types of Rechargeable Batteries Used for Solar Panels

Solar batteries can last between 5 and 15 years. The lifespan of a solar battery will be longer if you maintain it and protect it from extreme weather conditions. A batterys total lifespan is also impacted by the DoD. If you draw more energy out of the battery than is recommended, you may end up affecting your batterys efficiency.

Solar tubular batteries are fully tested deep cycle solar batteries that can be used in the off-grid solar system, hybrid solar system, solar home lighting system, and solar street lights for decades.

These solar batteries are specially designed as per solar application requirements. Tall tubular solar batteries are C-10 rated batteries with slow charging capabilities. For solar application, these batteries are required to be charge on low ampere. A lead-acid tall tubular solar battery requires to top-up with water every 3 to 6 months and can store more power than any other battery.

What Is Solar Battery

A solar battery is an energy storage device that can be paired with an off-grid and hybrid solar system. It is also known as a solar panel battery, solar power battery, or solar battery storage. Solar batteries are designed to connect with a solar charger controller or solar inverter for power backup. With a solar battery, you can store the extra power generated by your solar panels throughout the day and use it later as per your need.

Solar battery alters the way you use solar power. Installing a solar battery at your home allows you to use more of your solar power at home while purchasing less electricity from the grid. Your solar system will transmit power into the grid once your battery is fully charged. A solar battery might be worth considering if your grid electricity goes out frequently and you want backup power.

Can You Connect A Solar Panel Directly To A 12v Battery

Technically, you can connect a solar panel directly to a 12v battery as long as its not more than 5-watts, but connecting any higher-rated panels is not a good idea.

Solar panels will produce varying voltage outputs depending on the amount of sun hitting them, and this dipping and spiking of the voltage can quickly damage your battery.

Solar panels can generate up to 20v, which is much higher than the 12v required by a 12v battery. This can lead to overcharging, permanently damaging your battery.

The best course of action is to use a charge controller or regulator between the panel and battery, as this regulates the charge current and keeps your battery healthy.

This isnt a great sign, admittedly, so wed recommend returning on the lemon factor after trying for a few days if its charge and hold charge. Theres a 30-day return policy just for this reason, plus a one-year warranty.

Our Verdict

How Long Does It Take To Charge A 12v Battery With A Solar Panel

Typically, a 100-watt panel produces around 6ah per hour under ideal conditions or roughly 30ah40ah per day. If youre charging a 100ah battery from a flat, it will take about two days to fully charge the battery.

Its important to note that proper battery maintenance and care requires that your 12v battery never goes under 50%.

This is usually maintained by a charge controller, and so youll technically only need a panel that can produce 50ah per day to keep your battery fully charged.

Is Installing Large Hybrid Wind And Solarpanel Systems In The Burbs Just A Pipe Dream

Fitting larger wind and solar hybrid system to power your house in the Burbs is a long way off. Mainly because of local height and noise restrictions. You probably dont know those wind turbines can produce a bit of noise.

But if you live in a more remote area, you can go off-grid using a hybrid system. But for now, smaller systems are the way to go in towns and cities until the government says different.

The systems do cost a bit, and much bigger hybrid systems may be out of reach for the average pocket. But as the climate crisis deepens, governments around the world may start providing more monetary help.

Removing height restrictions may pave the way for the more affluent among us to take advantage. Many people say that giant windmills are an eyesore I can see it happening anytime soon.

But the people that say it may change their minds when it comes to having electricity or not. A few prolonged blackouts due to climate change might change opinions. It is only then the pipe dream will become a reality for the average person.
