As the UK embraces renewable energy sources to combat climate change and rising energy costs, the importance of having an efficient energy storage system has become increasingly evident.

The more you use your Solar PV system to satisfy your own demand for electricity, the better off you are. However, without some form of storage solution, your ability to do this is limited. This is because your demand for electricity may not match your production of electricity, and any electricity generated by your Solar PV system that is not immediately used goes straight to the grid.

Living in the UK, it’s clear that renewable energy, such as solar and wind power, fluctuates with the changeable weather conditions and is not always available when needed. This is where battery storage technologies come into play, they can provide a reliable and sustainable solution to storing excess energy.

When we think about renewable battery storage, most of us think of Tesla, which is the most popular and leading brand in the UK. However, as more and more of us look for sustainable solutions, more brands are coming to market.

In this blog, we will explore the role of battery storage, focusing on the impact of Tesla in revolutionizing renewable energy.

Renewable energy sources have come a long way over the last few years, and battery storage systems have emerged as the linchpin of a sustainable energy future. By capturing and storing excess energy, they bridge the gap between energy production and consumption, allowing renewable sources to provide reliable and continuous power.

Batteries offer several advantages, including peak load management, grid stabilization, and the ability to store energy for use during periods of high demand or when renewable sources are not generating power. Furthermore, they enable the integration of renewables into the existing power infrastructure, reducing reliance on fossil fuels and contributing to a greener grid.

Let’s take a look at the Tesla Powerwall 2

Tesla, is known for its ground breaking electric vehicles, and they have also made significant strides in the field of battery storage. Their expertise in battery technology has enabled them to develop cutting-edge solutions that are transforming the renewable energy landscape. One of their most notable contributions is the Tesla Powerwall 2, a home battery system that stores excess solar energy for later use.

The Powerwall is a sleek, wall-mounted unit that can be installed in residential properties. It acts as a personal energy storage system, allowing homeowners to maximize their use of clean energy by storing surplus solar power generated during the day and using it during peak evening hours or when the sun is not shining. This reduces dependence on the grid and provides homeowners with greater energy independence. The Powerwall also serves as a backup power source if a grid outage were to happen, ensuring a consistent electricity supply.

There are many advantages of the Tesla Powerwall 2 Battery. These include:

  • Environmentally responsible renewable energy storage solution
  • Flexible off-peak energy storage and consumption solution
  • Customisable grid power outage back-up solution
  • High energy storage capacity and power output
  • Long lifespan at close to peak efficiency
  • Low total lifetime cost per kW compared with alternative systems
  • The system is stackable allowing multiple Powerwall’s to be connected.
  • Quiet operation – emits less than 40 dBA at a distance of 1 metre
  • Settings are manageable from your mobile device using the Tesla Mobile App
  • Can be sited indoors or outdoors
  • Thermally maintained – battery continuously adapts to a very wide range of ambient temperatures to ensure efficient operation and long life
  • Sleek, modern, space-saving design
  • Market-leading brand from the world leaders in battery development

Another fantastic benefit of these batteries, is you can use a Tesla Powerwall as a standalone product with no Solar PV. 

The advantage of this is, you can make the most of your energy providers off-peak tariff, charging your battery from the mains during off-peak rates and then use this power in the day when the rates are higher. Subject to tariffs and authorisation from the DNO, energy can also be sold back to the grid and a Feed in Tariff received.

As you can see, there are many benefits to installing the Tesla Powerwall in your home and taking the first steps towards a sustainable future. As these products become more popular, there will be more affordable options coming to market.
