How and where to dispose of batteries in a sustainable way?

The battery technology just like solar PV technology continues to advance and today there are various types of batteries being used to help power equipment or store energy for electricity. As the solar PV sector continues to grow whether with on-grid or off-grid solar applications; the battery technology will help to accelerate the increased adoption of solar PV in domestic, commercial and utility sectors and other renewable energy technologies that are intermittent in nature like the wind energy.
Similarly, with the rapid development of electric cars in various countries, it means that we will see the demand for battery technology continue to grow exponentially. Solar PV and electric vehicles(EV) will definitely demand increased usage of the battery technology among other sectors that require batteries such as agricultural, commercial or even the household sector where batteries are used for TV remotes, flashlights, children’s toys and small electronics like cellphones.

However, even with these technological developments; how and where to dispose of batteries after their useful life is completed is one aspect of sustainability that will need to be tackled from a system thinking perspective. At the development stage of these batteries, it calls for implementing sustainable design to make it easy to recycle most of the components of the battery technology in question. For instance, researchers at the IBM research unveiled recently a new battery technology that will eliminate the need for heavy metals in battery production hence improving sustainable design.

As such, before looking into proper ways of disposing batteries, it is good to know what batteries are, the different types of batteries, and what they are made up of, making them something that requires proper disposal. Well, batteries are a collection of one or a group of cells that undergo various chemical reactions to create a continuous flow of electrons in a circuit.

Battery cells are generally classified into three components that is the anode, also known as the negative electrode, cathode, also known as the positive electrode, and finally, the electrolytes. For sustainability, the battery chemical composition will matter as it will guide how a battery will be disposed of after its useful life. For instance, in the USA, when it comes to lead-acid batteries, 99% of these batteries are collected and recycled.

However, according to the World Economic Forum, recycling lithium-ion batteries is a bit challenging due to the diversity of cell types and the broad range of materials such as an alloy of cobalt, nickel, and copper that may require manual sorting and handling or even smelting (pyrometallurgy) to recover individual metals or battery raw materials such as cobalt carbonate.

Types of batteries

There are many types of batteries classified according to their chemical composition, formation factor, size, and the purpose they serve. They include:

Primary batteries: These are a kind of batteries that cannot be recharged once fully used. These batteries are made up of electrochemical cells that their electrochemical reactions can also not be reversed. This kind of battery is usually used in devices that require no charging. Primary batteries are made up in a way that they provide high specific energy, and whenever used, the devices consume little power to ensure the battery has a long life span. The most common kind of primary batteries is alkaline batteries. They have higher specific energy levels, are environmentally friendly, and are cheaper to purchase.
Secondary batteries are the direct opposite of primary batteries. Secondary batteries can be recharged, and their electrochemical cells and electrochemical reactions can be reversed when all the energy has been fully used up. The secondary batteries are commonly known as the rechargeable batteries. Secondary batteries can be classified into different groups depending on their chemistry or chemical composition.
1. Lithium-ion: they are also known as Li-ion batteries. They are used in smart devices such as mobile phones and other battery home appliances. It has Lithium electrodes on it.
2. Nickel Cadmium: Also known as Ni-Cd batteries. They are made up of nickel oxide hydroxide chemical and the metallic cadmium as the electrodes.
3. Nickel-Metal hydride. This kind of batteries has the same chemical reaction to Ni-Cd batteries, which is nickel oxide hydroxide. Although, a negative electrode uses hydrogen-absorbing alloy, but not cadmium like the Ni-Cd batteries.
4. Lead-acid batteries: Lead-acid batteries are cheaper efficient power batteries that are used in heavy-duty applications. They are usually used in instances where they are non-portable because of their weight. Lead-acid batteries are used in an application that includes vehicle batteries for ignition and lighting and also as solar-panel energy stores. Lead-acid batteries are made up of acid that is used to ensure proper current flow in the circuit. Lead-acid batteries are the oldest form of secondary batteries and are relatively cheap compared to the other secondary batteries.

Where to dispose of batteries

Batteries are disposed of depending on the type which determines their chemical composition.

a) Household batteries: Household batteries can be classified into two groups, either rechargeable or non-rechargeable batteries. Disposing of the household batteries is not as complicated as disposing of the vehicle and industrial batteries.

According to battery solutions, alkaline batteries (AAA, AA, C, D, 9V, etc.) can be recycled using a specialized “room temperature,” mechanical separation process to recycle alkaline batteries.

The alkaline battery components are separated into three end products, that is, a zinc and manganese concentrate, steel, and paper, plastic and brass fractions. All of these products are put back into the market place for reuse in new products to offset the cost of the recycling process.

However, when it comes to rechargeable batteries, for example, lithium batteries are recyclable. They can, therefore, be disposed of at the battery recycling centers, electronic retailers who recycle batteries, or a waste collection site for hazardous materials. Therefore, ensuring you dispose of batteries properly.

b) Industrial batteries.

Industrial batteries can also be referred to as forklift or traction batteries. Industrial batteries can normally be drained to about 20% of the maximum charging capacity before a recharge.

Industrial batteries are manufactured with lead plates making them not disposable in the trash. Lead is considered to be a hazardous waste that is highly toxic to the environment. So when it comes to the industrial batteries, an estimated 60 to 80 percent of the used battery is normally reclaimed. More than 95 percent of the industrial lead-acid batteries are recycled.

The outer plastic shell is recycled to make some new plastic items, whereas the metal plates undergo purification to manufacture new batteries. In most states, there is a law that accepts the return of the industrial batteries to the retailer for disposal purposes. In case one cannot trace the retailer, they can contact the government officials for the information on the directions to follow to ensure proper disposal of the industrial batteries, industrial batteries maybe containing sulphuric acid that is harmful.

Safety precaution is normally advised when transporting the batteries for disposal. One should also avoid exposing the batteries to open flames or incidental devices like the cigarette lighters just for precaution measures.

c) Vehicle batteries: Car batteries are made out of lead-acid which is hazardous. It is, therefore, essential to dispose of it carefully just to avoid harmful side effects that can be life-threatening to human beings. There are many ways to dispose of vehicle batteries.

Returning the battery to a retailer. When purchasing the battery, there is normally a core charge fee certain retailers usually add in the receipts. This charge means that the battery is essential to the retailer. It can either be recycled or be rebuilt. Meaning that you can return the battery to the retailers, and they refund back your money with the same amount you paid as a core charge fee.
Taking the car battery to a recycling depot: You can check on the closest designated recycling depots near you on the internet and dispose of your car battery there for disposals.
Taking the car battery to an auto parts store: You can make your take battery to an auto parts store as you go buy another one.
Selling the car battery to scrap metal depot: One can decide to sell their batteries off to the scrap metal depot near them at a fee.
Taking the car batteries to battery recycling centers where they can recycle them and make something good out of them.

Each state has its own recycling program while resources such as Earth911 have a comprehensive online platform for helping online users decide on how to dispose of old batteries. Earth911 provides a recycling locator for all types of batteries where you just enter your zip code and it pulls the details for your specific battery and how or where to recycle them.

Call2Recycle is another online resource that offers a network of over 34,000 local recycling centers and drop-off locations for rechargeable batteries such as local municipalities and local retailers like Best Buy.

What are Portable solar panels for RV?

Portable solar panels for RV are solar panel kits that are off-grid and hence not connected to the grid and can be used to generate solar power for a recreational vehicle (RV).

Portable solar panels for RV are a great solution and an alternative to diesel generators providing clean power to your RV and saving you money at the same time. Portable solar panels for RV come with portable solar panels, adapter kits, battery, charge controller, and an optional power inverter.

How do RV solar panels work

An RV PV system requires solar panels connected to a charge controller to ensure that your batteries don’t overcharge and using the batteries to store energy charged from sunlight. The inverter is connected and is used to convert DC electricity to AC electricity. Proper cables are used to connect all the components together and after proper installation is done according to your RV roof size, you can start enjoying the benefits of solar power in your RV.

Advantages of portable solar panels for RV

RV solar panels help you to save money because once you have bought the solar panel kits, you don’t need to worry about fuel costs. It is a great alternative to diesel-powered generators. RV solar systems are almost maintenance-free because there are no moving parts in the RV PV system
RV solar panels give you the freedom to travel even to the most remote areas where there is no electric grid.
RV solar panels generate clean and quiet renewable energy as they do not burn fossil fuels hence they are good for sustainability.

Disadvantages of portable solar panels for RV

RV solar panels will need extra space on your RV and for RVs with limited space, this might be cumbersome.
Because there is no sunlight at night, and depending on the size of your RV solar panel system, you might need extra batteries which means more space is needed.

How much do solar panels for RVs cost?

Most portable solar panels for RV will have a power wattage of between 100 watts to 400 watts and depending on your power needs, that is, how many appliances you have in your RV and whether you are using your system for refrigeration; the ideal PV system is about 800 watts. Thus, assuming your 800 watts RV PV system has five (5) hours of direct sunlight, you’ll produce about 4,000Wh of solar power per day. Hence, the cost of your portable solar panels for RV will depend on your electrical load or appliances in your RV.

There are various brands of RV solar panels that you can buy online at Amazon, including but not limited to Renogy, Eco Worthy, HQST, and many others.

Why off-grid photovoltaics (PV)systems?

How has solar PV technology advanced?

With the decreasing cost of photovoltaics (PV), going solar is becoming more cost-effective and adoption rates continue to increase for both on-grid and off-grid applications. The solar PV technology continues to advance to provide power solutions for both businesses and individuals. From a very massive utility-scale power plant providing over 2GW (2000 MW) of generating capacity to a 4 or 5-watt panel for charging your cellphone or mp3 player, it is proof that solar PV technology has advanced and has very many applications. Research and development (R&D) efforts for photovoltaics continue with the aim of determining the right combination of materials to enhance or increase solar panel efficiency to generate more electricity per unit area of the solar panel.

When it comes to off-grid solar, more solar applications are developed with the aim of powering rural areas. Rural electrification, especially in developing countries, has been made more cost-effective since grid extension is still very expensive in rural areas. Scattered households and lack of a critical mass of households to make grid extension more cost-effective are one of the major reasons why the private sector does not find incentive in developing many rural grid electrification projects without subsidies from the government.

Many rural electrification projects using grid extension has remained a project for governments and non-governmental organizations. However, because of the reducing solar panel cost, the private sector is increasingly getting involved in many rural electrification projects that use innovative business models such as pay-as-you-go (PAYGO) and other off-grid solar projects to provide electricity to rural communities in developing countries.

Solar PV and rural electrification

With the right mix of technologies, off-grid solar PV systems can help to overcome the barrier to rural electrification without grid-extension. This can also take the form of off-grid solar PV combined with other sources of energy including, but not limited to wind power, bioenergy, geothermal, and small hydro resources. However, apart from solar energy, many of these other forms of renewable energy resources are site-specific and would work well where such resources are available and from a sustainable source.

Off-grid solar has numerous applications and solar is in abundance in most rural areas where it is needed because of its wider applications. A lot of food is grown in rural areas and off-grid solar would play a vital role in providing water from the wells through solar water pumping irrigation as well as other productive uses, especially in agriculture. Also, since many people have cellphones today, charging cellphones using solar power would be ideal, especially in areas not connected to the grid.

Off-grid solar also means portable solar solutions providing emergency power or standby power where there are many power outages. Some of these portable solar solutions include solar generators, solar battery chargers, and other portable solar gadgets. Solar lighting options for homes or street lighting are also applicable in rural areas.

Of all the above off-grid solar applications, solar water pumping for irrigation would provide many sustainability benefits in both short-term and long-term, creating jobs in the agricultural sector, especially in dry areas that can be transformed for growing food crops. On the other hand, off-grid solar would also provide a huge sustainability impact for homes through improving livelihoods with solar electrification.

Off-grid solar water pumping for irrigation:

For dry off-grid areas, solar photovoltaics can provide water for irrigation using solar water pumps and is more cost-effective compared to diesel-powered water pumps considering the long-term costs. The life-cycle cost of a solar water pump used for irrigation will be lower because once the solar water pump has been bought, there will be no lifetime fuel costs associated with the solar water pump.

However, a diesel-powered solar water pump will continue to rely on diesel over its lifespan. The solar water pump to be used will depend on many factors including the size of the farm, power rating (voltage rating), flow rates, and so on. There are two major types of solar water pumps: surface and submersible solar water pumps. Learn more about solar water pumps in this article.

Off-grid solar for rural electrification:

Rural electrification comes in many ways including, but not limited to grid extension, microgrids powered with renewable energy, or powered with fossil fuels. Powering rural areas using solar is increasingly being applied in many developing countries because of the reducing cost of solar panels. As such, solar PV is used as a clean technology to mitigate climate change with the right combination of technologies and with the right financial instruments.

Looking into the future, the centralized grid power system in rural areas will not be common as many investments will be used to develop decentralized power systems because of economics and the need to mitigate climate change using decentralized renewable energy systems. Also, solar packaged systems, as well as innovative business models such as pay-as-you-go (PAYGO) models, will continue to penetrate in rural areas of developing countries helping to provide affordable power to rural communities while mitigating climate change.

Renewable energy micro-grids such as off-grid solar PV systems with battery storage will overcome the high costs of grid extension. Standalone off-grid solar systems will be more ideal for rural electrification in areas where grid extension is expensive, and households not concentrated in one area, but scattered over a large area where grid extension could be expensive. Learn more about solar packaged solutions and rural electrification.

Five(5) benefits of a solar phone charger

With the growing environmental concerns of climate change and the decreasing prices of solar PV, solar energy is trending in many sectors, including but not limited to power homes and businesses. Also, portable solar solutions including portable solar chargers or solar phone chargers are trending with increasing awareness about renewable energy. This article attempts to explain five(5) benefits of using a solar phone charger:

A solar phone charger is portable and uses clean energy to help you charge your electronic devices. Once you have selected your solar cell phone charger, whose cost can be estimated to range anywhere from $50 to $200 depending on the brand and features included, a solar phone charger is very portable as it can be carried anywhere to charge your cellphone. A solar-powered phone charger comes in handy, especially used during traveling or outdoor activities. Since it is portable during the day when there is sunshine you can use it in your picnics, hikes or when camping to use it to charge not only your cellphone but also your iPad, portable speaker, humidifier, etc.
A lot of people especially in rural areas mostly in the developing world are not connected to the grid. As such, having solar chargers and other solar PV systems like solar panels and solar batteries are being used to produce power for both households and commercials helping to solve the energy access issue.
A solar phone charger would probably be the main source of energy in off-grid areas to power cellphones. For instance, in Africa, around 640 million people don’t have access to a grid and where some people do have access to the electricity supply is unreliable and unstable. As a result, solar PV has become one of the main sources of energy to power homes and businesses using one of the most consistent and promising approaches to tackling this huge obstacle to energy access, that is, off-grid pay-as-you-go solar power model, now called PayGo.
A solar phone charger uses solar energy – a renewable energy source. Even though energy from a solar charger might seem trivial or does not have an impact in terms of how much you can save when it comes to energy because cellphones or smartphones use a trivial amount of electricity. For instance, iPhone 5 uses 3.5KWh/year and costing about $0.41/year to charge them while Galaxy S III consumes 4.9 KWh/year at $0.5/year primarily because of the Galaxy’s larger battery. However, this might not impact you, but considering the aggregate impact (about 5 billion cellphones around the world) in terms of energy reduction from the grid and the increasing demand for mobile phones worldwide; your usage of the Sun’s energy to power your phone probably has an impact, if you look at it from a system’s perspective.
A solar phone charger is one step to energy efficiency when you aggregate the number of cellphones from a system’s perspective. Currently, there are about 5 billion cellphones around the world according to GSM intelligence. Users for smartphones are expected to increase by 2023 to over 7 billion. Smartphones consume more energy depending on how many wireless data the device is using as well as the amount of power consumed in making those wireless connections. As a result, when not using energy from renewables, a solar phone charger can help in reducing your carbon footprint.

From a system’s perspective, electronic gadgets or even electric vehicles powered using solar power will have an impact in terms of greenhouse gas (GHG) emissions reduced while increasing the energy efficiency consumed in the long-term.

Some of the best solar phone chargers have been reviewed on Amazon. When looking for some of the best solar phone chargers, it is important to evaluate the number of devices that can be charged, the time it takes to charge, and overall durability when selecting a model.

How much time does it take to charge a solar phone charger?

1. Why solar phone chargers?

With the rapid development of the solar PV technology, the benefits of the technology continue to increase since now we can use solar energy to directly power your cellphone and other gadgets in your household using, for instance, a portable solar generator or a stationary solar generator depending on your intended use of solar energy.

A solar phone charger comes in handy for people that do a lot of outdoor recreational activities such as hiking, camping, mountaineering, cycling, canoeing, caving, kayaking, rafting, rock climbing, running, sailing, skiing, skydiving, and surfing. Since most of these outdoor recreational activities involve traveling to remote places away from the grid, having a portable energy source would help to solve the problem, especially if you need to charge the battery of your cellphone when far away from the power grid.

In most cases, when people travel and need to charge the battery of their cellphones, they use their car chargers by plugging them in their car charging port to keep using their mobile phones. However, in some cases depending on the activity of the day, you will need to solve the problem with a solar-powered phone charger, especially when your recreational activity involves hiking, mountaineering, kayaking, etc.

One way to solve this problem is using a solar cellphone charger that incorporates an external battery pack attached to a series of solar panels that can be connected to the general electric supply or to the connector of an automobile vehicle lighter for charging the battery in the absence of solar light. Although it is a good thing to have a solar charger that can recharge all of your battery-powered electronic equipment such as your GPS, smartphone, camera, or flashlight and that can be recharged easily as well using solar panels.

2. So, how long does it takes to charge your solar phone charger?

Basically, a solar phone charger uses solar panels to charge a rechargeable external battery pack which in turn charges your cellphone. By knowing that solar panels would produce electricity even on cloudy days, your solar phone charger can charge the battery of your phone if there is some sunlight to trigger the electrons on your solar panels creating electricity (movement of electrons).

How long your solar phone charger takes to charge the battery of your cellphone depends on the wattage of your solar panel. High wattage means more solar power is harvested by your solar panel per unit time and depending on your external battery pack size, it is a matter of time depending on the types of solar batteries being charged.

3. Charging a solar phone charger.

Before we answer this question, let us understand the external battery pack that is being charged through the solar panels in your solar-powered phone charger. Solar batteries vary in several parameters, including capacity, output, size and weight and there are three types of solar battery banks:

• NiMH (Nickel Metal Hydride) batteries, usually the rechargeable AA or AAA batteries which are sold in packs.

• Lithium-ion batteries are the most common for portable battery backs.

• Lead-acid batteries not great for portability, because they are heavy and bulky, but very reliable when it comes to power output and capacity.

So, how long it takes to charge your solar-powered phone charger is a little complex and it is advisable to understand some electrical terminologies to understand the concept of charging your solar batteries:

• V — Voltage (electrical potential in the system, measured in volts). The higher the voltage, the more power you get out of a battery. A car battery has 12V and a USB port is usually fixed at 5V.

• Amps (A) – Current – the amount of electricity. General plugs are rated at 9A while big power devices like air conditioning (AC) systems are rated at 15A while smartphones draw current at 1A.

• Watts – Wattage (power measured in W) which is voltage (V) multiplied by Current (Amps)

Hence, if you have any of the above two numbers you can figure out any of the numbers. Batteries and gadgets like your smartphone are considered as small power and are measured in Amp-hours (Ah) or milliamp-hours (mAh) since 1Ah = 1,000 mAh which includes the rate of charging your solar battery bank.

Since most gadgets, including cellphones today, charge off USB (fixed at 5 V) we can calculate the time taken to charge your solar-powered phone chargers as (power bank capacity) divided by (power generated by the panel) using the parameters provided by the manufacturer. For instance, the manufacturer has set a certain number of amps needed to get a healthy charge in a reasonable amount of time.

So, if your cellphone is drawing a current of 1A we know that phones charge off USB at a voltage of 5 Volts, then such a cellphone draws 5V x 1A = 5W and considering for instance how long it takes to charge the following solar phone charger using solar? i.e. the Amazon, Solar Charger Power Bank 25000mAh Portable Charger Battery Pack with Three Outputs & Dual Inputs Huge Capacity Backup Battery Compatible Smartphone, Tablet, and More.

As we have noted above, this type of solar charger will depend on several factors. First, what is the current output of the solar panel? If the solar cellphone charger claims a 2W panel, it will produce electricity of 400 mAh at 5V (assuming there are no losses). That’s 400mA per hour, then if the capacity of this solar power battery is 25000mAh as rated, then 25000 mAh divided by 400mA is approximately 62.5 hours to fully charge your solar battery pack in the sun. Therefore, you probably need to buy a few pairs if you plan to stay outdoors for a long period while also plan to keep these solar battery packs topped off.

Powering your mobile-phone using a solar phone charger.

As the solar photovoltaics (PV) technology continues to advance we are seeing a lot of technological breakthroughs that use photovoltaics to help power homes, gadgets as well as businesses.
