The Top 3 Mistakes People Make When Choosing Solar – And How to Avoid Them

Making the switch to solar is one of the smartest decisions you can make for your home, your wallet, and the planet. But as solar grows in popularity across Ireland, so too do the number of people who rush into it without all the facts.

At Planet Blue Energy, we’ve helped hundreds of homeowners make the switch to solar—and we’ve also seen the most common mistakes people make along the way. Choosing solar is a long-term investment, and avoiding these three key mistakes can save you money, stress, and disappointment down the line.

Let’s break them down.

❌ Mistake 1: Focusing Only on Price

It’s tempting to go for the cheapest quote, especially when solar already feels like a big investment. But not all solar systems are created equal—and choosing the cheapest option often leads to higher costs in the long run.

Why It’s a Problem:

• Cheap panels may have lower efficiency and a shorter lifespan.
• Budget inverters or batteries might fail sooner, costing you more in replacements.
• Some low-cost providers may cut corners on installation or customer service.

 

A solar system is expected to last 25 years or more. Choosing the wrong equipment or provider just to save a few hundred euro up front can seriously undermine your long-term savings.

How to Avoid It:

Instead of shopping purely on price, look at:

• System quality: Are the panels Tier 1? What’s the warranty?
• Installer experience: Are they SEAI-approved and well-reviewed?
• Aftercare and service: Do they offer system monitoring, support, and maintenance?

At Planet Blue Energy, we only use proven, high-quality equipment that performs well in the Irish climate—and we back it with excellent customer support. Our goal is to give you the best value, not just the lowest price.

 

❌ Mistake 2: Underestimating Your Energy Needs

Some homeowners make the mistake of installing a small solar system that doesn’t meet their actual energy usage. This can lead to frustration when bills don’t drop as much as expected—or when they realise they can’t add a battery or EV charger without a full system upgrade.

Why It’s a Problem:

• A system that’s too small means you’re still reliant on the grid.
• You miss out on savings potential.
• It may not be future-ready for EVs, heat pumps, or smart home upgrades.

How to Avoid It:

Before installing solar, take a moment to look beyond today. Consider:

• Your current electricity usage
• Planned upgrades (e.g., electric car, home extension, more occupants)
• Your budget for battery storage or additional panels

A good installer will guide you through this. At Planet Blue Energy, we offer personalised consultations that look at your current and future needs, and recommend the right system size—not just the one that fits the minimum grant requirement.

While it’s possible to start with a solar PV system alone, many people don’t realise how valuable battery storage can be—especially with rising electricity prices and the changing energy landscape in Ireland.

Battery storage lets you:

• Store excess solar power to use later (especially useful in the evening)
• Reduce your reliance on the grid
• Provide backup during power cuts
• Take advantage of night-rate charging or future smart tariffs

Why It’s a Problem:

Some installers don’t offer battery-ready systems or fail to explain the benefits. As a result, homeowners find themselves stuck later, needing expensive upgrades just to add storage.

How to Avoid It:

Even if you’re not ready to install a battery now, make sure your system is battery-compatible. That means using an inverter that can handle storage, and choosing a reputable brand that supports future expansion.

Planet Blue Energy offers battery-ready systems and flexible upgrade paths, so you’re never locked out of future benefits. We also offer the latest in smart battery tech, including the Anker SOLIX X1—an ultra-fast, modular system that grows with your needs.

Bonus Tip: Don’t DIY the Grant Process

Navigating the SEAI grant application process can be tricky, especially if you’re trying to do it on your own. One wrong document or missed deadline could delay your installation—or cost you money.

At Planet Blue Energy, we handle the entire SEAI process for you, from start to finish. That includes submitting all paperwork, ensuring your system is compliant, and helping you maximise your grant.

Solar power is one of the best investments you can make—but only if you do it right.

To recap, here are the top 3 mistakes to avoid:

• Choosing solely based on price – Prioritise value and quality over cheap deals.
• Underestimating your energy needs – Plan for now and the future.
• Ignoring battery storage potential – Make sure your system is storage-ready from day one.

By steering clear of these common pitfalls and choosing a trusted provider like Planet Blue Energy, you’ll be set up for years of energy savings, lower bills, and a more sustainable home.
