I Want To Reduce My Electric Bill: Should I Fix My Energy-Leaking House or Buy Solar?

If you’re trying to bring your energy bill down, two options usually rise to the top: energy-efficiency upgrades or solar panels. Both can help, but figuring out what to do first (or whether to do both) is worth a little extra thought.

Energy-efficiency upgrades are all about wasting less—keeping heat in during winter and keeping it out during summer. That can mean adding insulation, sealing air leaks, upgrading windows, or replacing older heaters and appliances. The payoff is usually some combination of lower bills, better comfort, and a smaller environmental footprint.

Solar panels turn sunlight into electricity, which can lower what you buy from the utility and support a renewable energy future. Just keep in mind: while your electric bill may change, you’re also taking on the cost of the solar system.

Getting the system size right really matters. If you buy more solar than you can use, you may spend extra money without getting extra benefit. Solar credits are for what is used, not more.

When you cut waste and lower your usage with efficient upgrades, you might skip the solar or possibly install a smaller (and less expensive) solar system that still meet your needs. Here’s another way to think about it: buying a bigger solar system because your house leaks energy is like buying a bigger pump to empty water from a boat instead of plugging the holes. Being energy efficient helps you avoid paying for an oversized solar system you don’t really need.

Also, we’ve heard from members about solar sales pitches that make it sound easy to sign one contract and be done—without a wholistic approach about energy waste or ways to make the home more efficient first. Sometimes the message is “act now,” instead of “take your time and compare options.”

Columbia REA has a few suggestions that can help:

• Start by looking over our energy efficiency rebates at columbiarea.coop, and give us a call if you want to talk through your plans
• Connect with local staff at the Walla Walla Sustainable Living Center (slcww.org) or BMAC (bmacww.org) about getting an energy review. While you’re at it, ask about grants or other programs that could help with energy-saving improvements.
• Get a couple quotes from insulation companies, and ask what you might get back through Columbia REA rebates.
• Take a look at the energy-saving resources section on our webpage for ideas you may be able to tackle yourself.

Columbia REA has connected over 200 local members with their solar systems to date, and these systems add up to over 2.6 MW of power generation capacity. We are currently accepting applications for new Solar Net-Metering applications. Check columbiarea.coop for more information on solar including a live display of the Columbia REA solar systems.

We don’t endorse contractors or install solar systems, but we do recommend buying local and getting three bids.

In the end, the best choice comes from taking a full look at your home’s energy use, efficiency needs, your budget, and your longer-term goals. Talking with a few energy experts or contractors can help you understand your options and choose a path that fits your priorities. Whether you go with efficiency upgrades, then solar panels, or a mix of both, making a thoughtful investment now can move you toward a more sustainable—and more resilient—future.
