Retrofit Solar Panels With Battery Storage For A Brighter, Greener Future

Why Retrofit Solar Batteries?

For many years, homeowners have used batteries to store surplus power generated by solar panels. But their use was mostly limited to off-grid solar setups due to their cost and relatively modest efficiency. However, technology has advanced, the cost of batteries continues to decrease, and their efficacy improves, making them a feasible choice for grid-tied solar systems throughout the UK.

Therefore, retrofitting solar batteries to existing panels now brings a host of benefits, that did not exist a few years ago due to clumsy design, efficiency, and cost.

Combining solar batteries and panels allows you to make the most of solar power. When the panels capture the abundant energy from the sun unless you use it there and then, it is sent back to the grid. With a solar battery or a bank of batteries, you can store energy for your later use. This means you can enjoy free electricity even when the sun isn’t shining, such as during very dull days or at night. It’s like having a personal reserve of sunshine, providing reliable power 24/7.

One of the most compelling reasons to retrofit solar batteries to panels is the financial advantages. Lowering your reliance on the traditional grid could lower your bills. You can use the energy stored in the batteries during peak hours when electricity prices are higher. This strategy helps you save money and achieve long-term cost efficiency.

Additionally, having solar batteries as part of your solar energy system is a reliable backup, ensuring that essential appliances and devices continue to operate during outages. It gives you peace of mind and allows you to maintain a functioning household even when the grid experiences disruptions.

myenergi Bolt ID Green White

A modular battery system that adapts to your needs

myenergi created libbi to store your surplus electricity, to use it when you need it most. It allows you to capture as much surplus solar electricity as possible, whilst integrating with your existing myenergi devices.

libbi is modular by design. Each module can store up to 5kWh of electricity, so combining 4 of them together would provide up to 20kWh of storage.

Why Buy Battery Storage?

Energy Independence

Combining solar panels with a battery system makes you less reliant on the national grid, empowering you to have an independent energy source.


Environmental Benefits

Solar panels paired with batteries offer significant environmental advantages, helping combat climate change for future generations.

Maximizing Self-Consumption

Solar panels often generate more electricity than you can immediately use. With a battery, you can store the excess for later use.


Choosing The Best Solar Battery

Many people, particularly homeowners, embark on buying a solar system with limited knowledge. The market has adjusted to current needs by generalising what a customer can expect when investing in a solar system. This information is only sometimes accurate.

The range of solar battery options can make the process daunting. A one-size-fits-all approach may not always be the best choice.

As a leading Solar system installer throughout Kent, Tarven Solar Energy has many years of experience installing battery storage systems. Our experts advise those new to solar power on the best equipment to match their power usage and budget.

A Summary of Battery Storage Benefits

By combining solar panels with battery storage, you gain benefits such as energy independence, maximising self-consumption, backup power during power cuts, time-of-use optimisation during peak hours, and environmental sustainability. It’s a tempting proposal that offers financial advantages and empowers you to lead a more sustainable and self-resilient lifestyle.

Solar Battery FAQs

Solar battery storage refers to rechargeable batteries to store excess electricity solar panels generate. It allows homeowners or businesses to keep surplus energy produced during the day for later use, during the night or when the sun isn’t shining.

Solar battery storage systems are usually connected to a solar panel installation. When the solar panels produce more electricity than is being consumed, the excess energy is stored in the battery bank instead of being sent back to the grid. 

Combining solar batteries with panels, allows you to make the most out of your sun-generated free energy. Most of your generated power will be used in your home, instead of being sent to the grid. This capitalises on your investment, and can reduce energy bills

Unlike older models, which were chunky and heavy, modern solar batteries have a slim design and can be placed almost anywhere. Homeowners often choose to put them in the attic, garage, under the stairs or in a utility room. They can be placed outside, but it is important that they are away from direct sunlight and not exposed to rain.

The lifespan of solar batteries depends on several factors, including the type of battery technology, depth of discharge, regular maintenance, and environmental conditions. Generally, most solar batteries will last between 10 and 15 years. Lithium-ion batteries, commonly used in solar systems, have a longer lifespan than lead-acid batteries.

Yes, you can invest in solar batteries to use without solar panels. In this case, you will charge the batteries using grid electricity when the rates are low, usually overnight, and use the stored power during peak times when electricity rates are at their highest. 

However, it’s important to note that solar batteries won’t be able to generate free electricity without solar panels, but you can still save considerably on bills with smart technology.
