Why Your Home's Energy System Efficiency Isn't 100%

Home energy systems are fantastic add-ons to your house.

In the long run, they can help yousave on utility bills, but they’re not perfect.

That’s because no system is 100% efficient.

The amount of total electrical power successfully converted into usable energy indicates the electrical efficiency.

But why does it matter?

Here’s what you oughta know.

What is electrical efficiency?

Efficiency extends beyond the panels themselves.

But where does that “lost” power actually go?

“It’s not used, and it just goes away,” Omotalade said.

Energy might be lost for several reasons, like wasted heat or natural resistance within the system.

So now you know what electrical efficiency is, but why should you care?

Understanding efficiency can also help yousize your system correctly.

Efficiency also impacts cost, and higher efficiency products can be more expensive.

Omotalade says that electrical efficiency is also a matter of climate justice.

You might be wondering: What numbers should I actually be looking for here?

Let’s break it down.

It’s also important to note thatefficiency will decline as your solar panels age.

And of course, temperature can affect efficiency, too.

The numbers here are quite different.

Newer batteries can eclipse 90% efficiency.

Just like solar panels, battery efficiency is not static.

Here’s where you’re looking for the highest efficiency numbers.

Themost efficient inverterscan reach 99% efficiency.
