Buy Cheap, Buy Twice. The Hidden Cost of Saving on Solar

There’s an old saying that never gets old: buy cheap, buy twice.

It applies to almost everything in life, but when it comes to solar, it can be a very expensive lesson.

Every week, I speak with homeowners and businesses who were tempted by the “too good to be true” solar deal. A Facebook ad, a fast quote, and promises of huge savings. It all sounds perfect until the problems start showing up, the inverter fails, the app stops working, or worse, something starts overheating on the roof.

The Low-Price Trap

Let’s be honest, solar isn’t a low-cost product. Quality panels, proper electrical protection, and a compliant installation take time and expertise.
So when one quote comes in thousands cheaper than the rest, you have to ask yourself,  where’s the saving coming from?

Cheaper often means under-specified equipment, cut corners on safety, or unqualified installers. Some even use non-MCS-approved components, which invalidates your insurance and voids your warranty before you’ve even started generating a single unit of power.

The Fire Risk Few People Talk About

There’s a darker side to cheap solar that rarely gets mentioned, safety.
Poor-quality DC isolators, mismatched connectors, and undersized cables are a recipe for disaster. They overheat, they arc, and yes, they can cause fires.

We’ve seen melted isolators, burned junction boxes, and scorched roof timbers, all caused by installers who cut corners or used bargain-bin components to hit a price. The risk is real, and it’s not worth the gamble.

The Scaffolding Shortcut

Here’s something most people never think about,  if an installer doesn’t care enough about their own safety to use proper scaffolding, how much do you think they care about your property, your roof, or your risk?

We still see installers clambering up ladders with panels on their shoulders to save a few hundred quid. It’s reckless and illegal. What most homeowners don’t realise is that if someone is injured while working unsafely on your property, you can be held liable.

If a company isn’t prepared to invest in its own safety, you can be sure it’s cutting corners elsewhere. A professional solar business will always include compliant scaffolding in the quote, because the safety of everyone on site matters.

The Long Game

Solar is a 25-year investment. A properly designed system will quietly do its job year after year, lowering your bills and raising your property’s value. A cheap one might limp along for a while before the failures begin. By the time you’ve paid for repairs, replacements, and lost generation, that “bargain” system will have cost you more than doing it properly in the first place.

We’re often called in to fix failed systems fitted by others. In most cases, the client ends up paying almost double what a high-quality installation would have cost upfront. Painful lesson, easily avoided.

Pay Once, Not Twice

We don’t compete on being the cheapest, we compete on being the best.
Because real value isn’t about the lowest price, it’s about the longest life. The system that performs safely, efficiently, and reliably for decades.
