Is Solar Battery Storage Worth the Investment?

solar panel battery

Solar panels have become a common sight on rooftops in the UK.  This increase in popularity is driven by the dual desire to save money on energy bills and reduce environmental impact. With solar panels in place, the next logical step is to add a solar battery. This allows excess energy generated during the day to be stored so that it can be used later in the evening when it may be needed. But is it worth the investment? Like most things, the answer depends on individual circumstances and there are reasons why it will suit some customers better than others.

 

Benefits of Solar Batteries

 

1. Energy Independence

In the UK, peak electricity use occurs in the evenings when solar panels aren’t generating. Solar batteries can bridge this gap, allowing you to use your own stored solar power instead of relying on the grid.

2. Reduced Electricity Bills

Using stored energy during peak times can translate into significant savings on your electricity bills. In fact, MSC reported that an average household with solar panels utilised 35 – 50% of the generated system without a battery. However, with battery storage, this could reach as high as 80%! Increased rates depend on whether you are in the house for much of the day.

3. SEG Tariff vs. Self-Consumption

You can make money by exporting your excess solar electricity to the grid. However, the rate you are paid can vary. To get the best return you have to pick the best SEG tariff for your property. Having a battery allows you to maximise self-consumption (using the electricity that you generate) leading to greater financial benefit from your solar panels.

4. Grid Outages

Even when the grid goes down a battery backup system, will provide uninterrupted power. This added security is invaluable for critical appliances, home offices, and peace of mind.

5. Eco  Friendly

By using stored solar energy, you lower your dependence on the grid, which often relies on fossil fuels. This not only saves you money but also contributes to a cleaner environment.

 

Factors to Consider

 

1. Upfront Costs

While battery prices are becoming more competitive, a solar battery is still a significant investment. In addition, they come in a variety of storage capacities so it is essential that a qualified solar installer can help you choose the best solution for your property.

2. Energy Use Habits

As mentioned previously, the effectiveness of solar batteries depends on when you use energy in your property. If you use most electricity during the day, when solar panels are generating solar energy, batteries may offer less benefit.

3. Available Space

Battery units need a fair amount of space but can be successfully installed in a loft, garage or utility type area.

4. Return on Investment (ROI)

The payback period for solar batteries can vary significantly based on your energy consumption, system size, and electricity rates. A qualified solar panel installer can help you to calculate your projected ROI.

 

Are Solar Batteries Worth It?

 

While the advantages of solar batteries are clear, there are financial considerations. Solar batteries are a significant investment, adding to the upfront cost of your solar panel system. While battery prices are becoming more competitive, the initial outlay still needs to be evaluated. We advise contacting a reputable solar panel installer who will provide you with a personalised analysis. They will assess your specific circumstances and if it is right for you, recommend the most cost-effective battery solution for your needs.
