Glow Green are very professional, accessible and competitively priced company. They took us step by step through the process from start to finish. The installers completed the installation in one day and were very efficient, cracked on, tidied up, left no mess and kept us informed at all times with what was happening. It was a smooth professional process from start to finish. The panels are already saving and earning us money. Would highly recommend. Close

I am so pleased that I decided to have solar panels installed. After months of research I decided to go with Glowgreen Solar. The process has been brilliant from the start of the process, through install and beyond. Following my electricity company installing my new smart meter I was left with issues (totally unrelated to the work carried out by Glowgreen) which meant I needed to contact Glowgreen customer services for help. Following the install I have had 3 days of issues, which needed sorting out. Today I was put in touch with Richard Hughes, who dealt with my issues perfectly. Once the issues were resolved, Richard spent time sorting through my import and export settings. I have been left in no doubt that my decision to go with Glowgreen was undoubtedly the perfect one. I will happily recommend them to everyone who wants a solar installer. Also having previously quoted £19,000 for a 4kw system with 1 battery by another major supplier, I paid 25% less for more than double the input (8.7kw) and two storage batteries. Close

From sale to installation was a straightforward process and a very competitive price for 6 x panels, inverter and battery. My sales/customer service agent Carl was tremendously helpful throughout the process. Christian, the installer and his team were professional and efficient, working really well as a team and thoroughly explained the operation of my system, as well as arranging two weeks of beautiful 🌞☀️ so I can reap the rewards of my investment.😁 I would recommend this company.

We’ve had our solar panels now for 6 months and have been very happy with everything right from the off. Communications, promises delivered, install all excellent. Since then, we’ve been smugly watching the electricity our panels have generated, using it in the household, and exporting to the grid then we were forced to change our broadband router we were still generating just fine but could no longer get on the App to see what was happening.

A telephone call to Glowgreen had us speaking with Richard Hughes in the tech dept, who patiently walked us through the procedure to connect Solis with our new broadband router resulting in instant connection. He even took the time to remotely check out our system and recommended a few small ‘tweaks’ to make sure it’s running efficiently. Overall a very positive experience and it’s left us feeling very happy to continue to recommend Glowgreen. Close

The sales team were very knowledgable and could answer all my questions, unlike other companies I contacted. The installation team listened to me, could answer all my questions. They were efficient, polite and did a great job. They gave me a walkthrough of my system and App before I left. Glow Green then contacted me to check everything was to my liking and let me know that I could go through them if I have any issues or concerns. A great company.

Tesla - The Global Leader in Battery Storage Solutions

Worcester Bosch Style 8000 Boiler

Tesla is widely acknowledged as the Global Leader in providing high capacity lithium batteries for their Electric Cars, Grid Storage Solutions and Domestic Solar Energy Systems - accelerating the world’s transition to sustainable energy.

Their newest Solar Battery, the Powerwall 3, is designed specifically for your home. Each Powerwall 3 battery contains a market-beating 13.5 kWh of usable energy storage and a massively improved power output so you can use this energy when you need it.

Worcester Bosch Style 8000 Boiler

When your PV Solar System generates more electricity than you need, you can store the extra energy in your Powerwall 3 and save it for later. Your Powerwall 3 can also recharge from the grid to take advantage of cheap overnight electricity tariffs. With customisable power modes, you can optimise your stored energy for outage protection, maximum electricity bill savings, and more.

Up to four of these batteries can be connected together to provide a massive combined storage capacity of 54kWh – ideal for large domestic properties, schools, retail shops, offices, warehouses and other commercial premises. And if you need even more storage, the good news is that Tesla is intending to provide greater expansion flexibility soon.

Use your Powerwall 3 with ANY compatible make of Solar Panels

Whilst Tesla Solar Panels are not available in the UK, the good news is that you can use a Powerwall 3 with Solar Panels from leading manufacturers like Perlight and DMEG-C. It’s the smarter choice for larger homes.

With GlowGreen, you’ll get expert advice on choosing the right battery solution for your home from one of our experienced, knowledgeable and friendly consultants with no high pressure sales tactics. And when you are ready to commit, we’ll be here to help with the lowest prices and award-winning service.

Why choose a Tesla Powerwall 3?

Selecting the right battery for your home isn’t just about the price and storage capacity. There are other important factors you need to consider including:

The Discharge rate

The discharge rate is a measure of how much stored energy you can use each hour. A good way to understand why this is important, is to compare it with a large tank of water connected to your bath by a pipe - the bigger the pipe coming from the bottom of the tank, the faster you can fill your bath.

And this really matters, because if the energy you are consuming each hour is higher than the discharge rate, then the excess will come from the Grid instead of from your battery. Increasing your electricity bill, and reducing your potential savings.

The Powerwall 3 features a higher discharge rate compared with any other leading solar battery.

The Charging Rate

The Powerwall 3 supports up to 20 kW DC of solar input each hour and includes sophisticated energy management and backup capabilities - that’s over double the solar input rate of other leading panels, making it ideal for larger solar roofs with 20+ panels.

The Length of Warranty

The Powerwall 3 comes with an industry standard 10 year warranty, but the good news is that you can expect your battery to last much longer than this even though the amount of usable storage will reduce steadily over time.

The Number of Cycles

Each time the battery is charged and discharged (filled and emptied) is known as a ‘cycle’. The Tesla Powerwall 3 has unlimited cycle coverage, which means that the battery can be used as much (and as often) as needed without any restrictions. The Powerwall 3's 10-year warranty remains valid for the entire period, regardless of how many cycles the battery completes.

Weatherproof

The Tesla Powerwall 3 has a weather-resistant enclosure, so you can install it either indoors or outdoors, and it can operate in a variety of conditions ranging from -20°C to 50°C. To prevent damage, you should avoid installing the Powerwall 3 near water sources like downspouts, sprinklers, or faucets, and also ensure snow doesn't accumulate around it.

How does the Powerwall 3 stack up against the competition?

Here’s a table which compares the key features of the Tesla Powerwall 3 against a number of other leading battery options:

  • Usable Capacity: 13.5 > 54kWh
  • Maximum Discharge Rate: 11.04kW
  • Maximum Solar STC Input: 20 kW
  • Warranty: 10 years
  • Usable Capacity: 2.6 > 47.5kWh
  • Maximum Discharge Rate: 3.6kW
  • Maximum Solar STC Input: 7.5kW
  • Warranty: 12 years
  • Usable Capacity: 4.6 > 73kWh
  • Maximum Discharge Rate: 6kW

What's Right for You?

The new Tesla Powerwall 3 has been upgraded to be a fully integrated solar and battery system, designed to meet the needs of a standard UK home.

No need for a separate PV inverter anymore, direct connection to your Solar array saves space, is more energy efficient and gives you control and visibility of it all through one great App on your phone.

Connecting up to a maximum of 20kW of PV Panel power single phase and 60kW on 3 phases, Tesla Powerwall 3 can be the powerhouse of your home

You can also make the most of special tariffs with ultracheap energy during restricted hours overnight when there is little demand and wholesale costs are lower. You can use this to charge your Powerwall 3 from the Grid (at prices that could be as low as 10p/kWh), and then use that stored energy during the remainder of the day when Grid prices are typically over 30p/kWh - that means you could save 20p/kWh (or even more) on all the electricity you use!

Your stored energy is available whenever you need it - during the day, at night, or when an outage occurs. A Powerwall 3 can power your entire home, including lighting, electric heating or hot water, A/C, as well as other large appliances.

Whatever your motivation, our Tesla Powerwall solution offers great looking, superior performance and durability, with award winning customer service at a market leading price.

Some customers cannot install Solar Panels because they live in conservation area, or their roof is unsuitable for some reason. But that doesn’t mean they can’t use a Powerwall 3 to reduce their energy bills.

Many energy suppliers offer special tariffs with ultracheap energy during restricted hours overnight when there is little demand and wholesale costs are lower. You can use this to charge your Powerwall 3 from the Grid (at prices that could be as low as 10p/kWh), and then use that stored energy during the remainder of the day when Grid prices are typically over 30p/kWh - that means you could save 20p/kWh (or even more) on all the electricity you use!

There are a number of Major Components That Make up A Solar PV System

Solar Panels

Solar Panels take the energy from the sun’s rays and convert it into DC electricity.

Inverter

The inverter takes the DC energy from your roof (or battery) and turns it into AC electricity you can use in your home. There are two types of inverter: ‘String’ inverters are for cheaper systems that don’t have any battery storage, and ‘Hybrid’ inverters which are needed if your PV system also has a battery. With the Powerwall 3, the Inverter is included within the battery.

Battery Management System

Depending on the manufacturer, this might be built into the battery, or provided separately. For Tesla, this is all built in.

The Tesla Gateway

The Tesla Gateway is an essential part of their solution – it’s effectively their Home Energy Management System. One Gateway can support up to four Powerwall 3 battery packs.
