Yes — battery backup systems are designed to work alongside solar panels, and pairing the two is one of the most effective ways to maximize your energy independence. When your solar array produces more power than your home needs, excess energy charges the battery bank instead of being sent back to the grid. During a grid outage or at night, that stored energy powers your home without interruption.

How Solar and Battery Storage Work Together

A solar-plus-storage system has three main components: the solar panels themselves, a battery bank (usually lithium iron phosphate chemistry in modern installs), and a hybrid inverter or dedicated battery inverter that manages the flow of power between panels, batteries, grid, and your loads. The inverter is the brain of the system — it decides in real time whether incoming solar should charge batteries, power your circuits, or both.

In Colorado, this pairing makes strong practical sense. Our intense high-altitude sunlight gives solar panels more productive hours per day than lower-elevation markets, which means more energy to store. During wildfire smoke season, though, production can dip — so a properly sized battery bank provides a buffer when your panels are underperforming.

What Integration Actually Involves

If you already have solar, adding batteries isn’t always plug-and-play. The key question is whether your existing inverter is “battery-ready” (sometimes called a hybrid or multi-mode inverter). If it is, integration may be straightforward. If you have an older string inverter, adding storage often means replacing or supplementing it with a hybrid model that can communicate with the battery management system.

Done’s electricians assess your current solar setup — inverter type, panel capacity, existing interconnection agreement with your utility — before recommending a battery solution. Xcel Energy and Black Hills Energy each have their own interconnection rules for storage-plus-solar systems, and we make sure your installation meets those requirements so you don’t run into billing or compliance issues down the road.

Grid Independence: How Much Can You Realistically Achieve?

True 100% grid independence is possible but requires careful system sizing. Most homeowners find that a solar-plus-storage system covering their critical loads — refrigerator, lighting, internet, medical equipment, select outlets — is the most cost-effective starting point. Full-home backup through multi-day cloudy stretches requires significantly more battery capacity and potentially a generator as a tertiary backup.

In Denver and the Front Range, we tend to see short but intense outage events (storms, high-wind days, grid stress during heat waves) rather than multi-week blackouts. For most households, 10–20 kWh of storage paired with a solar array covers those scenarios comfortably. Your usage patterns, panel output, and budget all factor into the right size — which is why a proper load analysis comes before any equipment recommendation.

Colorado Incentives for Solar-Plus-Storage

The federal Investment Tax Credit (ITC) applies to battery storage systems when they are charged primarily by solar — verify current rates with a tax professional, as percentages are subject to change. Colorado also has state-level incentives and some utility rebate programs that may apply to your installation. Done can walk you through what’s currently available and help you document the installation for incentive purposes.

  • Federal ITC may apply when battery is charged by solar (confirm with your tax advisor)
  • Colorado RENU Loan program offers low-interest financing for renewable energy upgrades
  • Xcel Energy and Black Hills may offer rebates — eligibility varies by rate class
  • Net metering agreements can affect how you size storage vs. grid export

Next Steps

Whether you’re adding batteries to an existing solar system or planning a combined install from scratch, the process starts with understanding what you have and what you want to protect. Done’s team handles the electrical design, permitting, and installation — and we’ll make sure your new battery system is fully compatible with your solar equipment before any work begins.
