This Is The Way Tesla Power Walls Work

Recent reports suggest that the cost of renewable energy sources such as wind power or a solar installation has fallen below the cost of traditional energy sources such as coal. However, one of the biggest problems with harnessing solar power is storage. The solar cells can only produce electricity during the daytime and that power needs to be stored somewhere in order for it to be used in times of need.

This is where the Tesla Power Wall comes in. You must have heard of Tesla, the electric car company. It is the company that is spearheading the race for electric vehicles and it is the biggest electric vehicle maker in the world today. In 2015, the company announced Tesla Power Wall which is a battery for the home.

In simple terms, it is a rechargeable lithium ion battery similar to the batteries you have in your mobile phones that can be recharged hundreds of times. This rechargeable lithium ion battery can be hooked up to solar panels or the electric grid in order to be charged. In other words, think of the Tesla power wall battery as a huge mobile phone battery that hangs off the wall.

Once the battery is fully charged, it is capable of feeding the energy back into the electric grid in case there is an excess or just store the energy in order for you to use it at a later date. Currently, the battery is available in two variants, 7 kWh and 10 kWh.

For a regular home, the 7 kWh battery should suffice. The company claims that it will charge during off-peak hours and the stored energy can be consumed during peak hours. The bigger battery is aimed at bigger homes as well as businesses. In case you have a bigger requirement, you can always buy multiple batteries and hook them up together in order to meet your needs.

The company claims to have sold thousands of these units to homeowners all around the world. As far as the cost is concerned, you will need to check online in order to figure out the cost of this battery in your location. You will also need to pay for the installation of the battery and that will add to the cost. In order to calculate whether investing in this battery makes financial sense for you, you will need to calculate the cost of energy in your location and then compare it with the savings you will make by investing in this rechargeable lithium ion battery.

One of the biggest advantages of this particular battery is that this is guaranteed by the company for 10 years which means you won’t need to replace the battery for a period of at least 10 years. Therefore, when you are calculating your costs, you need to take into account the fact that you are making an investment for 10 years. Most estimates available online suggest that owners should be able to breakeven in around five years. However, your breakeven point will depend on the cost of energy in your area.

There are also some concerns by prospective buyers whether this battery pack will look good in their home. It is a very well-designed unit that just hangs off the wall and looks great. So, you do not need to worry about the looks of this battery packs.

Overall, the Tesla power wall batteries work like just any other battery. The biggest difference is that these batteries are guaranteed for a period of 10 years which makes them financially viable for most households and hopefully, spark a rise in the number of solar power installations.

Different Kinds of Renewable Energy

More and more frequently, people are looking for a way to power their homes and businesses without having such a strong impact on the environment. For years, services have used and perhaps even abused the earth in an effort to provide electricity for their customers. That electricity was generated with coal, oil and other types of nonrenewable resources but today, people are looking for renewable forms of energy. There are a number of options available and we will consider a few.

Before we talk about the types of renewable energy, it’s important to consider the benefits of using them on a regular basis. In most cases, these types of services can be set up rather conveniently and the return on investment from the installation is going to be relatively quick. One of the benefits of using renewable energy is the fact that it continues to work on an ongoing basis and once it is put in motion, it requires very little maintenance. Regardless of the type of renewable energy service that is being considered, this will be true.

The following 3 types of renewable energy are being used today. In fact, the technology that is associated with these types of energy is growing and as it does so, the use is growing as well. They provide the ability to power our homes and businesses without having a severe impact on the earth.

Solar Power Although there may be many different forms of renewable energy, one of the most convenient and most powerful is the energy that comes from the sun. When it is able to be harnessed properly, it could easily be converted into usable energy and the possibilities are truly endless. Here is a basic understanding of how it works.

Solar power gathers energy from the sun. The sun is putting out energy on a constant basis and even though only a very small part of that energy reaches the earth, it is thought to be enough to provide for our needs many times over. The power from the sun is collected by something that is known as a photovoltaic cell. That cell has the ability to take the energy from sunlight and convert it into usable electricity.

A single photovoltaic cell is able to produce a very small amount of energy but those cells are often put together in panels and together, they can gather a lot of energy for our use. In fact, there are times when these panels are even put out in farms that may span many acres. The energy that they produce can then be channeled into the grid and ultimately, into our homes and businesses.

Wind Power The wind is another form of usable energy and in essence, it is also a form of solar power. After all, the sun heats the earth and as the earth is spinning, the uneven heating is what causes the wind and weather patterns.

A wind turbine will typically either have 2 or 3 blades and as the wind blows, the blades will turn. The blades turn a shaft that ultimately, goes into a generator and the generator produces usable electricity. In its most basic sense, the wind turbine uses the wind to create mechanical energy and then the mechanical energy is converted into electricity.

Hydroelectric Power This type of power uses the movement of water, regardless of whether it is a river or the tides in the ocean. It does so in a similar way to wind power, in that the water movement turns a shaft that causes a generator to create electricity. This type of renewable energy is already in use and it can be seen in dams around the world. Additional resources are being considered for using the tidal forces, and it may just produce enough electricity to power our needs for many years to come.

These 3 types of renewable resources are not only a possibility, they are already a reality as they are already being used. Around the world, renewable electricity is being produced more and more frequently and as it is produced, it is replacing the type of electricity that abused the earth through nonrenewable resources.

How Do Renewable Energy Tenders Work In South Africa?

There are many contracts, or tenders, that will allow people to bid on projects. This could be for anything industrial or commercial. Renewable energy has become a very strong focus for people around the world, especially in countries like South Africa. The population of the world continues to grow and the demand for renewable sources of energy is continuing at a very high pace. People are able to get contracts in South Africa for building renewable energy centers, many of which are desperately needed by people in this area of the world. Let’s look at how renewable energy tenders work in South Africa, and why this could be what will save this country from its dire need for electricity.

Why Focus On Renewable Energy?

Renewable energy is not just a primary focus in countries like the United States. It is also in demand worldwide. Some people believe that is a transition from fossil fuels to renewable energy sources that is the focus. However, it’s usually just about being able to provide power for individuals and companies that need it. Most electricity is produced through hydroelectric dams, but they can only produce so much. Likewise, there are ways of producing biofuels which can be used by diesel engines, as well as producing charcoal by using recycled materials in landfills. There are many projects in South Africa, renewable energy tenders that you can bid on, but you have to know where to look.

What Are Renewable Energy Tenders?

The word tenders simply refers to a contract or bid. It is a promise to complete a certain project. Renewable energy tenders are very popular right now. There are businesses that produce energy through solar panels, windmills, and pyrolysis plants. As long as there is a way to profit from this type of installation, companies will line up to install machinery that can produce the renewable energy. South Africa is definitely a place where people are growing in technology and industry, with more people coming into this area of the world all the time. Therefore, renewable energy projects have become a primary focus because they are more affordable to build. These tenders can be found in South Africa if you know where to look.

How Do They Work In South Africa?

Tenders are typically divided up into sectors, regions, and countries. They are also divided up by each type which could include construction projects, fabricated products, and building renewable energy sources. You can go to websites where you can see all of the tenders that are current for the continent of Africa. By searching for the tenders that are specifically in South Africa, you can see which ones are currently happening and open for bidding. They are often divided up into location, a summary of the project, and the deadline by which it must be completed. By searching for renewable energy sources or clean energy sources, you will get the product code and all of the listings. This will allow you to find information on who to contact so that you may be able to build one of these renewable energy plants.

Current Popular Renewable Energy Projects In South Africa

One of the more popular ones involves the conversion of biomass into electricity. This is done through the process of pyrolysis. It will generate a significant amount of heat which can create electricity, but there are also byproducts including coal and biofuels. They may also have many renewable energy tenders related to producing electricity from the sun and the wind.

There are always going to be quite a few renewable energy tenders in South Africa. To bid on projects, simply do the search and find the contact information. Look at the ones that need to be done soon and bid on the project. If you can find some in South Africa that pertain to your particular industry and renewable energy, you may be able to successfully get one of these projects to build a renewable energy plant. Of course, you will need to meet with the people in that area of the world. The proper permits will need to be filed. Once it is set up, you will be able to help an area of the world that so desperately needs renewable energy sources.

Robben Island Solar Power Solar Power Micro System

Robben Island Adopts A Solar Power Micro System

If there is one thing that is true across the board for most people around the world, it’s the fact that they need energy in order to go about their day-to-day lives. From turning on the bathroom lights in the morning all the way to cooking food, electricity has become an important part of the mix. The problem is, much of the world’s electricity is produced using nonrenewable resources, such as coal or oil. This can really put a strain on the environment but there are some places, such as Robben Island, that are making a difference.

There are many different types of alternative energy sources and some of them use renewable resources in order to power and generate the energy. A good example of this is solar power, and the use of solar cells is able to collect the power from the light of the sun and generate electricity that can be used in homes and businesses. This is often seen on a smaller scale but at times, it can even be used on a larger scale as well. That is what they did on Robben Island, and it has really made a difference in the way that they use the environment around them.

Many governments have put laws into to place that stipulate a certain amount of power must be generated by renewable resources, such as solar, wind or hydroelectric power. What took place on the island, however, goes far beyond the small percentage that is often seen in these laws. It is thought that the diesel usage on an annual basis is going to drop by almost half an the use of diesel generators is going to drop by an amazing 45%. This project is going to save a considerable amount of money but it will also save the environment in some rather unique ways.

The way that the power is being generated is by means of a solar power microsystem utilizing a photovoltaic farm. On that farm, a number of PV arrays are put in place and all through the day, they collect the light of the sun and continually generate usable electricity from it. Of course, there is also power that is needed during the night and at times, the sun may not be shining during the day but the system is able to overcome this problem in a way that really shows us the possibilities for using solar to power the world’s energy needs.

Along with the PV farm, there is also a battery storage facility that uses lithium-ion batteries and a series of controllers to harness the energy from the sun and to store it in case it is needed for use during the nighttime and for days when it may be cloudy and the available sunlight is reduced. Since it is fully put into place, it is possible for Robben island to operate fully on solar power nine months of the year, which really shows the possibilities for what can take place in other parts of the world.

This is something that is part of what is known as the Green Tourism Incentive Programme (GTIP) and it was developed in order to maintain some of these tourist attractions and to do so using forms of renewable energy. There are also additional sites that are going to be using renewable energy to power their needs as well, including Kruger National Park and the Free State National Botanical Gardens.

In some cases, the use of these PV arrays is put into practice on a farm that is used for a variety of other purposes, such as maintaining the local wildlife or perhaps allowing for grazing of local herds. The farm on Robben Island is not used for other reasons as the majority of it is filled with the PV arrays and for the facility using battery storage.

This solar power microsystem really shows how important it is to continue to develop the ability to harness the natural resources around us and use them for our own needs. By using solar power and other renewable resources, it is possible to provide enough power for the majority of our use and to do so without causing any irreparable harm to the Earth.

Tesla Car: How Does It Works?

Just how do Tesla’s electric cars really work? The reply to this question needs a little more explanation. The fundamentals are fairly simple, however actual interest lies in the details of that futuristic car technology.

Electricity charges a battery to provide the Tesla’s car power for a particular time period, the same thing with your laptop or smartphone. Tesla electric car has a lot of similarities with your MacBook, more than you may think – the firm utilizes lithium-ion batteries the same as the type which powers laptops all over the world.

There is only one difference – Tesla’s batteries are far more powerful. The battery in every Tesla car is in fact comprised of thousands of lithium-ion cells which have a total weight of around a thousand pounds, based on the company. Every pack is created at Tesla’s Bay Area head office and comes with a heating system which allows the car to work even in winter.

In order to get that battery all set to roll, however, you are likely to need to charge the sucker. Once again, this method is not very much different from how you charge the mobile gadgets you carry around each day – what is special here is you are handling a much larger gadget which carries you all around instead. And that is the main distinction between a Tesla electric car and the hybrid car – it’s all electric and has to be charged, whereas the Prius runs partially on gasoline but doesn’t have to be charged.

There are some methods to try charging your Tesla electric car. Tesla suggests acquiring an electrician to set up a recharging station at your house. Known as a High Power Wall Charger, this gadget connects to the back of the vehicle and could power the battery two times as fast as the 120-volt outlet would. Also you can connect to 100-volt outlets using a mobile connector which allows you to charge everywhere you find electricity and time. And, of course, you can always go green by setting up solar power panels to produce charge at home.

However there’s still more – Tesla is also in the way of setting up hundreds of “supercharging” stations in roads throughout the United States and in areas of Canada. These stations are made to let Model S owners to charge their vehicles in only around an hour, and a few have been constructed in California.

Thus exactly what does that electricity get utilized for? To power a watermelon-sized engine which turns mechanical power directly into electricity and also converts that mechanical power right into more electrical power. It is a more simple, more efficient unit compared to combustion engine present in the majority of cars, helping you to make the most mileage for your charge. Tesla claims its electric cars designed with the strongest battery packs available could go at 55 mph for approximately 300 miles on one charge.

Certainly, at some point you will run out of juice and the entire process will start again. However now you will have an appreciation for the way the Tesla electric car really works.

Home Batteries Tesla Power Batteries Tesla Powerwall

Tesla Power Batteries

Despite having fewer rebates and lesser feed-in tariffs than previously, much more households are setting up solar power systems to cut back power bills and make their houses more eco-friendly.

In other interesting information for potential – and present – solar panel-owners, the release of Tesla’s Powerwall home battery implies homes can get a lot more from their solar power systems.

What’s the Tesla Powerwall?

Tesla talks about the Powerwall as a “rechargeable lithium ion battery with liquid thermal control.” It’s among the few firms in the household energy storage market which makes small-scale batteries for house energy storage. The first-generation Powerwall released in April 2015, and an upgraded Powerwall 2.0 was introduced around October 2016. The cost of a Powerwall 2.0 battery (excluding installing expenses) is $5,500.

Tesla battery packs are a perfect pairing for solar panel systems, particularly in the event of off-grid projects in which homeowners require or wish to become completely independent of their power. The solar storage option such as the Tesla Powerwall enables you to sustain a power supply in the daytime or night.

One big constraint of solar photovoltaic (PV) systems is they do not produce electricity in the evening (naturally!) thus they are still dependent upon connection to the grid for night-time power and when the solar array or inverter breaks down for whatever reason. However the Tesla home battery could store the solar-generated electrical power to be used later.

The idea of a home battery storage system is not new; they have been around for a long time, like those coming from Solar Australia. Some other electrical power storage systems (battery as well as other technologies) are made for large-scale industrial or commercial use. However Powerwall might be a game-changer for the electricity sector.

How much it cost?

The list cost to get a new Tesla Powerwall 2.0 battery, that provides two times the storage capacity of an original Powerwall, is $5,500. Supporting components gives one more $700 to the equipment expenses, which gives the sum of $6,200. Installation can also add from around $2,000 to $8,000 to the overall bill.

It’s important to remember that the list costs you see do not cover the expense of installing your Powerwall in your property. Tesla quotes that particular installation will put $800 to $2,000 into your bill. Then again, this estimate does not cover the expense of electrical upgrades, permit fees, taxes, or connection costs. EnergySage customers have claimed installation expenses which add anywhere from around $5,000 to $8,000 (prior to any financial incentives are applied). The total number will be primarily based on the particulars of your installation.

If you wish to install the Powerwall as part of the solar-plus-storage system, battery expenses are simply one portion of the equation. A typical 5 kilowatt (kW) solar energy system rates anywhere from around $8,500 to $16,000 depending upon your geographical area and the kind of equipment you select. That might appear to be a lot of cash, however installing a solar-plus-storage system could be a worthwhile expense.

Why is Tesla’s home battery different from others?

Compared to other Tesla technology, Powerwall is open patent, that will enable competitors to create the same or even much better products. Thus even though Powerwall isn’t the first such system to show up, this could be the one which makes battery storage systems a standard feature in houses.

For an average house, Powerwall and a solar array altogether can turn into the primary source of power, having the grid connection serving just as a back-up and top-up for extended periods of low sunshine. Nevertheless, the system can also let total self-sufficiency for a few houses.
