As more homeowners across Hertfordshire and Essex look for ways to cut energy bills and reduce reliance on the grid, two technologies are leading the way: solar PV panels and battery storage systems.
But one of the most common questions we hear at JJB Electrical Ltd is: “Do I need both, or will just one be enough?”
In this blog, we’ll break down the differences, explain how each system works, and help you decide which option (or combination) makes the most sense for your home.
What Is Solar PV?
Solar photovoltaic (PV) panels convert sunlight into electricity that you can use to power your home. They’re fitted to your roof and produce electricity whenever there’s daylight. Benefits of solar PV include:
- Lower energy bills.
- Renewable, clean energy.
- The ability to generate your own power rather than buying it all from the grid.
The limitation is that panels only produce during daylight hours. If you don’t use the power straight away, it’s either exported back to the grid or wasted, unless you have a battery to store it.
What Is Battery Storage?
Battery storage systems allow you to store electricity and use it later. Most people combine batteries with solar, but you don’t have to, they can also charge from the grid. Benefits of battery storage include:
- Using more of your own solar power.
- Charging at off-peak grid rates and using energy during expensive peak times.
- Protection against blackouts (with certain systems).
- Greater independence from energy suppliers.
The limitation is that a battery doesn’t generate power, it only stores what you already have. That’s why many households pair batteries with solar.
Solar PV vs Battery Storage — Which Should You Choose?
The answer depends on your home, energy usage, and long-term goals.
Solar PV Only — If you want to start generating clean energy and reducing bills right away, solar panels are a great option. Many households in Hertfordshire and Essex see immediate savings.
Battery Storage Only — If you don’t have the right roof for panels — or you’re not ready to install them yet — a battery can still make sense. By charging overnight on cheaper tariffs, you can cut your bills and prepare your home for future solar.
Solar PV + Battery Storage — For the biggest savings and the greatest independence, combining both is the smart choice. Solar panels generate power, while the battery stores it for evening use. Together, they can dramatically reduce your reliance on the grid.
Local Examples
- Hertford: A family fitted solar panels first. A year later, they added a battery and increased their self-use of solar power from 40% to 85%.
- Cheshunt: A homeowner installed battery storage before solar, using cheap overnight tariffs. When they later added panels, their system was already set up.
- Harlow: A couple combined solar, a 10kWh battery, and an EV charger installation. They now power their home and car almost entirely from renewable energy.
Key Considerations
1. Roof Suitability — If your roof is south-facing with little shading, solar is a strong choice. If it isn’t ideal, starting with a battery may be better.
2. Energy Usage — Families who use most of their energy in the evening benefit most from adding a battery.
3. Future Plans — If you’re planning an EV, solar and batteries together can provide clean charging.
4. Electrics — Some homes may need a consumer unit upgrade or rewiring before installation.
Costs and Return on Investment
- Solar PV only: The quickest payback, especially if you’re home during the day to use the power.
- Battery only: Savings depend on your tariff and usage, but can still be significant.
- Solar + battery: Higher upfront cost, but also the greatest long-term return.
