How Do I Pick the Best Solar System Size for My Home?

Choosing the right solar system size can feel like a puzzle. Oversize it, and you might pay more upfront than you need. Undersize it, and you’re still stuck paying the utility for a big chunk of your electricity. Sundog Solar’s goal is to strike a happy balance—meeting your energy demands efficiently while giving you room to grow. Colorado has plenty of sun, 300 days per year on average throughout most of the state, so you want to take advantage of the energy you have!

Start with Your Usage

We look at your past 12 months of electric bills to see exactly how many kilowatt-hours (kWh) you typically use. This tells us whether you’re a light user (running mostly LEDs and a few appliances) or someone with an electric vehicle, AC, or workshop in the garage.

Factor in Future Needs

Planning to add a heat pump, a hot tub, or an EV in the next few years? We size your panels and battery capacity so you’re not “maxed out” the moment you upgrade. This forward-thinking approach saves you time and money in the long run. Because we include a battery with every installation, we also calculate how much backup power you’ll want during outages or peak-rate times. The ability to store your excess daytime solar means you can use more of it at night—reducing or even eliminating your reliance on expensive grid electricity.

Some companies might push you toward the biggest system possible. At Sundog Solar, we focus on meeting your actual goals—whether that’s net-zero energy usage or covering expected future use. Our job is to simplify your choice and present options that make sense for both your wallet and your lifestyle.
