Why opt for a solar battery?

A solar battery allows you to store electricity generated by your solar panels, or directly from the energy grid, to use when you need energy the most. Using battery storage alongside solar panels allows you to be even more self-sufficient, reduce your reliance on the energy grid, and avoid energy price increases. Soly offer solar batteries along with solar panels, or we can provide solar battery storage on its own.

Make the most of your energy

With a solar battery, you can store self-generated power from your solar panels, to use it later on.


Direct savings on energy costs

Import less electricity from the grid and save money on your energy bills.


Control your system at your fingertips

Control and track your solar panel and battery system with our easy-to-use app.

How does a solar battery work?

During the day, your solar panels generate power constantly, but this is often when homes use the least electricity. This surplus electricity can be sold back to the grid, but if you want to become even more self-sufficient, you can store it in a solar battery and use the energy when you need it at nighttime, or at a later date.

With a smart solar battery from Soly, you can increase your independence from the energy grid from 40-60%, to 60-80%.

What is a home battery?

When installing a home battery, the Solar Battery becomes part of the existing system of solar panels, microinverter, and grid. You’ll likely have a surplus of generated energy. The battery will store excess power which you can draw from when your solar panels are producing too little or no power.

How much does a solar battery cost?

Curious about the cost of a solar battery? If you’re looking for a battery combined with solar panels, you can easily calculate the price in our Solar Panel Cost Calculator. Or you can simply request a free offer by getting in touch with our team.

We can provide you with a no-obligation indication and calculation of the cost and yield of a home battery based on your current situation. Payment plans are available*.

What’s the service life of a home battery?

A home battery operates on charge cycles. UK households will normally use 345 cycles per year, and the Enphase home battery from Soly has a lifespan of 6,000 cycles or 15 years, whichever is longer.

What is the payback period of a solar battery?

Based on current energy prices, a solar panel system will pay for itself within a few years. With a home battery, this is slightly more complex. To calculate the payback period of a solar panel, we would need to look at three factors: price, storage capacity, and your energy consumption. Once we have this information, we can calculate your payback period. Book a free consultation call to get more information.

What are the advantages of a home battery?
A home battery allows you to temporarily store solar energy for later use. The greatest advantage can be found in the efficiency of your (renewable) energy consumption. Thanks to a home battery, effective use of energy from solar panels increases from around 35% without a solar panel battery, to as much as 70–80% with a home battery.
What are the features of a home battery?
The features of a home battery primarily relate to its capacity and dimensions. The dimensions of a home battery can vary considerably depending on the type of battery. For example, the size of home batteries ranges from one to two shoe boxes. By the way, your home battery will be installed in a space-efficient place. You will therefore not be inconvenienced by it.
What is the storage capacity of a home battery?
The storage capacity of a home battery varies and depends on the number of solar panels on your roof. At Soly, we use a home battery with a storage capacity of 3.5 kWh, 7 kWh, or 10.5 kWh.
