Is It Better to Have Battery Storage?

Do I need a battery?

Why would you need a battery to store the energy from your solar panels?

Read our article of the things to think about when it comes to battery storage.

The global shift towards renewable energy sources has seen a major rise in the adoption of solar power systems. Solar power is a clean, renewable, and sustainable form of energy that has proven to be a viable alternative to traditional fossil fuels. However, the intermittent nature of solar energy—only available when the sun is shining—creates a challenge. This is where solar and battery storage comes into play. But is it better to have battery storage for solar panels? Let’s jump into this question.

Understanding Solar and Battery Storage:

Before we can answer whether it’s better to have battery storage for solar panels, it’s crucial to understand what exactly solar and battery storage is. In simple terms, a solar panel system with battery storage allows you to store excess energy generated by your solar panels during the day for use at night or during power outages.

Solar panels convert sunlight into electricity which powers your home appliances. Any surplus energy produced is stored in the battery instead of being sent back to the grid (for not much money back). When the sun goes down or on cloudy days when your panels aren’t producing enough electricity, your home can draw from this stored energy. This means you can use your own produced energy when you need it, not just when the sun is out.

PROs of Solar and Battery Storage:

There are several reasons why having battery storage for your solar panels can be beneficial for you.

1. Energy Independence: With a battery storage system in place, you’re less reliant on the grid as you can store excess power generated by your solar panels for later use. This means even during peak hours or power outages; you’ll still have access to electricity.

2. Lower Electricity Bills: By using stored solar power during peak times when electricity rates are high, you can significantly reduce your utility bills. And once your battery has filled up you can then receive money back for the energy you send back to the grid.

3. Reduced Carbon Footprint: By using renewable energy stored in batteries instead of drawing from the grid, which often relies on fossil fuels, you are reducing your carbon footprint and contributing to a more sustainable / greener future.

4. Increased Solar Efficiency: Battery storage ensures that none of the power generated by your solar panels goes to waste. This increases the overall efficiency of your solar power system, making the most of all the energy you have produced.

CONs of Solar and Battery Storage

While there are plenty of benefits to having battery storage for solar panels, it’s also important to acknowledge some downsides.

1. High Upfront Costs: The cost of installing a battery storage system can be quite high. However, this cost can be offset over time through savings on electricity bills. This is shown through a simple ROI (Return on Investment). Where your designer / installer should show you how much time it will take your energy savings to payback your initial investment.

2. Maintenance: Batteries need little to no maintenance, but in time will need to be replaced. But this is usually well after they have paid for themselves a number of times over, and if not that’s what the average 10 year warranty is for.

3. Space Requirements: Depending on the size of the battery storage system, you will need to find a decent location for the battery to be located.

Is It Better To Have Battery Storage For Solar Panels?

The answer largely depends on your personal needs and circumstances. If you find that you use most of your electric at times when the sun is down (evening, night and early morning), then a battery is essential to make the most of your solar production. Similarly, if you’re committed to reducing your carbon footprint and becoming more energy independent, investing in solar and battery storage is a great step forward.

However, if the upfront costs are prohibitive or if you don’t have sufficient space for installation, it might not be the best option for you at this time.


In conclusion, while there are both benefits and challenges associated with solar and battery storage systems, they offer an excellent solution for maximizing the use of renewable energy sources and achieving energy independence. As technology continues to advance, prices continue to drop and energy prices continue to rise, it’s likely that more households will opt for this sustainable energy solution in the future.

Here's what our customers say:

'NSN installed our solar system and I found them to be friendly, knowledgeable and professional throughout the whole process from the initial enquiry, through the design stage, installation and system handover. The installation went according to the schedule and any queries I had were answered promptly.'
Electrical Installation Testimonial
''From our initial discussion and visit to us by Joss and Alex, the recommendations and plans of the PV panels for our property to the installation, including the scaffold team and the roofers, has all been a very well-organised process. The actual installation, fixing the panels on the roof, was excellent. They all worked professionally and respectfully. We have no hesitation in recommending your company. Thank you again.

Frequently asked questions

What kind of warranty do you offer on the solar panels?

Our solar panels come with a 25-year efficiency warranty. This means that for a quarter of a century, you can have peace of mind knowing that your panels are guaranteed to perform.

What will I really save on my energy bills?

By switching to solar panels, you can reduce your energy bills by 75-80%. Additionally, you’ll be protecting yourself against future electricity price hikes, making it a wise long-term investment.

What does an inverter do?

A solar inverter is an essential part of any solar PV system as it converts the direct current generated by the solar panels into alternating current so that it can be used to power electrical appliances.
Without a solar inverter, all of the free renewable solar energy being generated by the panels would simply go to waste.
