Our solar panel battery storage solutions

Also known as an energy storage system, solar panels with battery storage are a superb way to become more energy-efficient, drastically lower your energy bills, and live more sustainably. Here’s an idea of how solar panel battery storage works works:

  • Electricity generated from your PV solar panels is stored in a battery
  • The battery provides power to your home when needed
  • If the battery runs out of power, the system will automatically draw power from the grid
  • You can even store excess electricity and sell it back to the National Grid

Why add a solar battery to your solar panel system?

The addition of solar panel battery storage to your existing solar energy equipment will open up another world of benefits, both in terms of cost savings and eco-friendliness.

Pros of having solar panel battery storage

You can store excess energy

A solar battery can store the excess energy that’s produced during the day for later use, such as at night or during a power outage

Reduced reliance on the grid

If you have a solar battery, you can use less electricity from the grid, saving you money on your energy bills and reducing your carbon footprint.

Backup power during an outage

Your solar battery can provide backup power during a power outage, so you won’t have to rely on generators or candle

Passive income stream

Depending on how much electricity you generate, you could make a lucrative passive income by selling excess energy back to the grid.

How it works

Installing a solar panel battery is pretty straightforward. To get an idea of what a battery installation could cost you or to see if you’re eligible for solar battery grants from the ECO4 scheme or Solar Together scheme, follow these three simple steps, and you’ll soon be benefiting from clean and free solar energy.

You must have lots of questions. We’ve answered some of the most commonly-asked questions about batteries for solar panels and solar battery grants here, but please speak to the team if you have any more.

What is the best type of battery to use with solar panels?

There are two main types of solar batteries used with solar panels: lead-acid batteries and lithium-ion batteries. Lead-acid batteries are the most common type of battery, and they’re relatively inexpensive and have a long lifespan. However, they are also heavy and require more maintenance than lithium-ion batteries.

Lithium-ion batteries, on the other hand, are more expensive than lead-acid batteries, but they have a higher energy density and a longer lifespan. They’re also much lighter and require less maintenance.

At the end of the day, the best battery to use with your solar panel installation is the one that serves your property’s energy needs most effectively. If you have any questions about which solar battery to add to your solar energy setup, speak to our team, who’ll pass on their expert advice.

How long does a 5 kW solar battery last?

The type of battery you choose will affect its lifespan. Lead-acid batteries typically last 3-5 years, while lithium-ion batteries can last 5-10 years.

How many batteries do I need for a 5 kW solar system?

This will depend on how much energy you use, but there’s a simple rule-of-thumb formula that you can use to work out how many batteries you might need.

Number of batteries = (your energy needs/battery capacity) divided by 2

So, for example, if you use 20 kWh of energy per day and your battery capacity is 5 kWh, then you will need 4 batteries. If you’re in any doubt, though, we’re always on hand to help!

How many solar batteries are needed to power a house?

The number of solar batteries needed to power an average 3-bedroom house depends on a few factors, including the size of your solar panel system, your energy needs, the climate you live in, and the type of battery you have. In general, though, you will need 1-2 batteries for a 3-bedroom house with a 5kw solar system. However, if you have high energy needs or live in a cold climate, you may need more solar panel battery storage.
