If you live in Perth, Dundee, or the rolling hills of Angus, you know two things are certain: the scenery is world-class, and the energy bills can be a bit of a nightmare. With the cost of living still biting and the Scottish weather being, well, unpredictable, more and more Tayside homeowners are looking to take control of their energy.
But here is the million-pound question (or at least the several-thousand-pound one): should you go for solar panels first, or is an air source heat pump the better priority?
At Herofix, we help local families make this choice every day. While both are fantastic upgrades, there is a "missing link" that often gets overlooked, and it's the one thing that makes the whole system actually work for your wallet.
Let’s dive into the great Tayside energy debate and see which path is right for your home.
The Case for Solar Panels First
When most people think of renewable energy, they think of solar panels UK wide. Even in sunny Dundee (officially Scotland’s sunniest city, let’s not forget!), solar is a massive win.
Installing solar panels allows you to generate your own electricity during the day. For a typical family in Perthshire, this means running the washing machine, the dishwasher, and the telly for free while the sun is out. It’s a "top-down" approach, you’re tackling your electricity bill first.
Pros:
- Immediate impact: You’ll see your electricity meter slow down the moment they’re switched on.
- Low maintenance: Once they’re on the roof, they just get on with the job.
- Property value: Buyers are increasingly looking for homes with solar already installed.
Cons:
- The "Daytime" Problem: If you’re at work all day, that free energy is being sent back to the grid for pennies, while you’re paying full price for electricity in the evening.
The Case for Heat Pumps First
An air source heat pump is a "bottom-up" approach. Instead of focusing on your gadgets and lights, you’re tackling the biggest energy hog in your home: the heating.
If your old gas or oil boiler is on its last legs, switching to a heat pump can be a game-changer. These clever units pull heat from the outside air (yes, even when it’s freezing in Brechin!) and move it into your radiators and hot water tank.
Pros:
- Massive Grant Support: Currently, the Home Energy Scotland grant offers up to £7,500 towards a heat pump. In some cases, you can even get the whole thing covered via the ECO4 scheme.
- Future-proofing: Gas boilers are eventually being phased out. Getting ahead of the curve now makes sense.
Cons:
- Electricity usage: Heat pumps run on electricity. If you install one without solar, your electricity bill will go up (even if your gas bill disappears).
The Secret Ingredient: SOLAX Battery Storage
Here is where things get interesting. Whether you choose solar or a heat pump first, neither system reaches its full potential without home battery storage.
At Herofix, we’ve tested almost every battery on the market. Our #1 choice for Tayside homeowners? SOLAX.
If you install solar panels, a SOLAX battery stores that free daytime energy so you can use it to power your lights and oven at night. If you have a heat pump, the battery can help run it using stored solar power, making your heating virtually free.
Battery comparison: how SOLAX stacks up
Quick look at the alternatives
Tesla Powerwall 3 is a well-known option and suits homeowners who want a premium, all-in-one battery from a major global brand. It offers a strong 13.5 kWh usable capacity and a tidy design, but for many Tayside homes it can be a bit less flexible when you want to build a system in stages.
GivEnergy All-in-One 2 is a popular choice for households that want a larger-capacity unit with strong monitoring and smart tariff compatibility. It makes sense for bigger energy users, but it can feel like a larger upfront commitment if you are only just starting with solar or planning to add a heat pump later.
Fox ESS EP12 is often considered by homeowners looking for a more budget-friendly route into battery storage. It gives you a respectable amount of storage and can work well in the right setup, but it does not offer the same simple step-by-step expandability that makes SOLAX so useful for growing homes.
Why SOLAX is still our top pick:
Modularity that suits real Tayside homes: Not every home in Perth, Dundee or Angus needs a huge battery on day one. SOLAX lets you start smaller and add more storage later, which is ideal if you are upgrading in stages or planning for a future heat pump.
LFP safety: They use Lithium Iron Phosphate (LFP) chemistry, which is the safest type of battery storage available. It’s stable, durable, and far less prone to overheating.
Durability in our climate: SOLAX units are IP65 rated, so they are well suited to the cooler, damper conditions we see across Tayside. That extra toughness matters in garages, utility rooms, and exposed installation spots.
A better all-round fit than the big-name alternatives: Tesla, GivEnergy and Fox ESS all have their place, but SOLAX gives homeowners the best balance of flexibility, safety and long-term value. For local homes that want to grow their system over time, it is simply the more practical choice.
Industry-leading warranty: With a 10-year warranty on their Triple Power range, you’ve got total peace of mind that your investment is protected.
The Verdict: Which Should You Install First?
If you can do both at once, that is the gold standard. But if you’re doing it in stages, here is our expert recommendation for Tayside homes:
Option A: The "Solar + SOLAX" Start (Recommended)
For most people, we recommend starting with Solar Panels + a SOLAX Battery. Why? Because it gives you an immediate reduction in your daily bills. You’ll become much less reliant on the grid, and you’ll have the battery infrastructure ready to support a heat pump when you decide to swap your boiler later. It’s often the most logical path for solar panel payback.
Option B: The "Heat Pump" Start
If your boiler has just died and you’re facing a cold winter, go for the heat pump first. With the £7,500 grant, it’s often cheaper than replacing a traditional boiler. Just be prepared to add solar and a SOLAX battery down the line to help offset the running costs.
Don’t Forget the Grants!
As heat pump installers across Perthshire and Angus, we always tell our customers to check their grant eligibility first.
- Home Energy Scotland: £7,500 grant for heat pumps, plus interest-free loans for solar and batteries.
- ECO4: If you meet certain criteria (like being on specific benefits or having a low EPC rating), you could get solar panels, batteries, and a heat pump completely free.
