15th Feb 2022

Imagine a home that’s not only powered by the sun but can also keep the lights on when the sun goes down or the grid goes out. As energy independence and efficiency become top priorities, solar battery storage is the game-changing solution, providing accessible electricity around the clock.

The good news is that solar battery storage aligns perfectly with The Little Green Energy Company’s (TLGEC) mission. Here’s what you need to know.

What Is Solar Panel Battery Storage?

Solar battery storage captures the excess energy generated by your existing solar panel system and stores it for use during low-sunlight hours, peak energy rate times, or power outages. Instead of sending all excess power back to the national grid, the battery captures and keeps this clean energy on standby.

How it works?

Understanding the basics of how solar panel battery storage works is simple:

1. Solar panels produce direct current (DC) electricity when exposed to sunlight.
2. DC electricity passes through an inverter, converting it into alternating current (AC), which is the type your home uses.
3. Excess energy that isn’t used right away is stored in your battery for later.

 

4 Key Benefits of Solar Battery Storage

Investing in a solar battery offers significant benefits for you, your wallet, and the planet.

1. Energy independence

With a solar battery, you’re not at the mercy of the grid or energy companies’ rate hikes. Instead, you rely on the power you generate and store – a level of self-sufficiency that brings peace of mind, especially during power cuts.

2. Cost savings

Solar battery storage can significantly reduce energy bills by allowing you to tap into your own stored energy rather than purchasing expensive peak-hour power. Homes with a solar system and battery storage report average savings on electricity bills of up to 85%.

3. Reduced carbon footprint

Each kWh of solar power you use from your storage system reduces your dependency on the grid, which often relies on fossil fuels. TLGEC’s clients take pride in their reduced carbon footprint, knowing they’re promoting climate goals while saving money.

4. Grid stability

When homes use a battery-stored energy during high-demand times, they lessen the strain on the grid. Collectively, this reduces the likelihood of blackouts, contributing to a more resilient energy system.

 

Types of Solar Battery Storage Systems

Choosing the right battery depends on your energy needs, but here’s a quick look at the main types:

1. Lithium-ion batteries: These batteries are the most widely used in residential solar installations because they offer high efficiency, long cycle life, and excellent energy density.
2. Lead-acid batteries: This type is less expensive but generally less efficient, with a shorter lifespan. It’s best for an off-grid solar installation where budget is a concern.
3. Flow batteries: These batteries use liquid electrolytes to store energy, which makes them well-suited for larger setups, such as commercial or industrial applications.

 

Tesla Powerwall: The Little Green Energy Company’s Preferred Solar Battery Solution

TLGEC specialises in installing Tesla Powerwall lithium-ion battery systems, which set the standard for efficiency, reliability, and intelligent design in solar battery storage.

Key features:

• High capacity: Each Tesla Powerwall unit comes with a 13.5 kWh storage capacity.
• Uninterrupted power supply: The Powerwall automatically switches to stored energy, keeping your home’s essentials running without interruption.
• Advanced battery management: The system allocates energy based on your usage patterns, weather forecasts, and grid demand.
• Load shifting: A Tesla Powerwall battery can be added to any new or existing solar PV setup—or even installed on its own to enable load shifting. This allows homeowners to buy energy during off-peak, lower-cost times and store it for use during peak hours.
• Smart integration: The Powerwall uses the Tesla app to share insights on energy production, battery status, and consumption patterns.
• Durability and warranty: Tesla Powerwall units have a 10-year warranty and an expected lifespan that often exceeds this timeframe.

 

Choosing the Right Solar Battery for Your Home

Finding the right battery is crucial for maximising your solar investment. Here’s what you should consider:

1. Storage capacity: A higher capacity means more power in reserve.
2. Power output: High output (57 kW) is ideal for homes with multiple appliances.
3. Efficiency: Higher efficiency means less energy loss in charging and discharging, directly impacting your savings.
4. Lifespan and warranty: Long warranties and reliable lifespans will ensure your investment lasts. Our SunPower Solar Panels come with a 40-year warranty, whereas the Tesla Powerwall solar battery has an additional 10-year warranty.

 

Cost Considerations and Financing Options

While solar battery storage is a significant upfront investment, the long-term savings often make it worth every penny. The typical cost for residential battery systems starts at around £4,000 and can reach up to £10,000, depending on capacity and brand. Battery installation usually adds £500 to £2,000.

To make the initial investment easier, TLGEC offers financing through Hometree Finance. This includes flexible options like zero-deposit plans and monthly payments.

 

Maintenance and Longevity of Solar Batteries

Today’s solar batteries require little maintenance, but occasional care ensures they work at peak performance:

• Regular checks keep the system running smoothly and catch potential issues early.
• Battery monitoring lets homeowners track performance over time.

We are committed to long-term client satisfaction. That’s why we offer maintenance and inspection even on systems we didn’t install. Rest assured – you’re guaranteed support and performance for years to come.

 

Conclusion

Solar battery storage isn’t just about cutting energy bills – it’s about gaining control over your renewable energy, supporting a cleaner future, and enjoying the security of energy storage. For those ready to make the switch, TLGEC brings years of expertise, ISO 9001 certification, and a portfolio of successful installations – backed by 5-star reviews.
