How Much Does a Solar Panel Battery Cost?

A solar battery is usually an added cost on top of the cost of solar panels. Depending on the capacity, you might be looking at paying an extra €1,500 to €4,000 on top of what you pay for the installation.

Solar batteries allow you to store the energy produced by your solar panels for later use but you can also get paid for exporting any excess energy your solar panels generate through the microgeneration scheme.

By selling your excess energy back into the national grid, you can offset some of the costs incolved in installing solar panels.

Can I Get a Grant for Solar Panels?

Fortunately, you can get a grant to help bring down the price of a solar panel for your property. 

The SEAI solar grants scheme offers significant funding to make the cost of the solar panels more affordable. However, the grant only applies to photovoltaic solar panels so if you want to install a different type you’ll have to pay for it yourself.

If you invest instead in getting a solar panel kit, you can save immensely on up front costs but you won't qualify for the SEAI grant.

Here’s a breakdown of how much a solar panel might cost you with the SEAI grant:

Why Are Solar Panels So Expensive?

Taking into account their manufacturing costs, their installation costs, as well as their maintenance, the amount you have to pay for having your own solar panels can be quite challenging

Here are some of the factors that might influence the cost your solar panels in Ireland:

  1. Type of Solar Panel
    There are many different types of solar panels and each one has its own cost. The different types of solar panels will have different ways of producing electricity than others and this can invariably affect the amount you pay.

  3. Batteries
    You might also want to invest in getting a battery to store the electricity generated from solar power to use later. These can also vary depending on capacity and the quality.
  4. Installation Costs
    Installing the solar panels on your property is one thing but having it done well is another. You’ll want to make sure that you’ve had the best quality installation so you don’t have problems further down the line and this can be quite

  2. Return on investment
    The return on investment is measured by the length of time it takes for your solar panel to have paid for itself. This is essentially how much you have saved on your electricity bill by having a solar panel installed.

Some people might just prefer to have enough solar panels to put a dent into their energy bills and are on a budget. However if you want to use solar panels as your main energy source, it’ll cost you a bit extra.

To find out how many solar panels you need for your home, have a look at out solar panel companies article and get a quote for your property.

How Are Solar Panels Measured?

The quantity of photovoltaic solar panels you need is measured in different ways to what you might expect. Instead of counting the number of solar panels you get installed, you order the capacity of the panels that you require for your property.

The capacity is measured in kilowatts (kW) known as its rated capacity. You can then calculate how much electricity you’ll be expecting to get after installation.

Example of Solar Panel Capacity If we have a solar panel with a capacity rating of 1kW. This means that for every square metre of sun, the solar panel will generate 1000 watts. 

Are Solar Panels Worth It in 2024 in Ireland?

So are solar panels worth the cost in Ireland? There are a lot of pros and cons surrounding solar panels.

On one side, they’re the ideal investment for today since we’re all moving towards renewable energy sources and need to keep the green transition going. They're also a great choice and alternative to getting an electric vehicle for instance.

What Are the Solar Panel Pros? ✅

  1. Cheaper Electricity Bills
    With your own energy source, you’ll start making savings on your electricity bills almost instantly so you won’t be paying an energy company as much every month. You’ll also have a bit of protection against later price hikes.
  2. Grants Available
    Grants are available for solar panels unlike for other renewable energy. The SEAI grants significantly reduces the upfront cost for your solar panels so you don’t have to worry too much about prices.
  3. Good Return on Investment
    Since your return on your investment will be over 20%, that’s a really great return after you’ve made the money back.
  4. Better for the Environment
    Naturally, investing in your own solar panels is the best way to invest in renewable energy for the rest of Ireland. It’s also one of the best ways that you can do your bit for the environment. 

What About the Solar Panel Cons? ❌

  1. Hefty Upfront Costs
    The upfront costs are extortionate in some cases given the technology and the skill needed for the installation process. Hopefully one day these costs can be brought down to make it easier for people without as much in savings to install one.
  2. Grants Are Limited
    Though the SEAI grants help with bringing down the cost, at the end of the day it still doesn’t make much of a dent in the price of the solar panels.
  3. Investment Takes a While To Earn Back
    Although it's a worthwhile return, it does take a while to earn back, especially if you spend a lot of money on solar panels in the first place. 3 to 4 years might be too long to wait!
  4. Solar Panels Sometimes Unreliable
    Solar panels are sometimes unreliable and unusable in cloudy weather, so you should definitely assess where you live and whether you get a lot of sunlight before you buy your solar panels - it might affect your return!
