A 30-panel solar array in New Richmond.

Thirty REC 450-watt panels with Enphase microinverters, split across the garage and house roofs. The system is sized to offset about 87% of the home's electric use.

Two roof planes meant two separate conduit runs and mounting layouts. It let us spread the array across the best-oriented sections of each building. Running our own crew on a property this spread out kept the wiring and inspection points consistent across both roofs.

If your property has multiple structures, solar doesn't have to live on just one roof. An 87% offset still leaves you tied to the grid, not off it.

A 45-panel REC array in Bethel, Ohio.

A system this size spans more roof than a single plane can hold. Splitting the panels across available roof area let the crew hit the target output without crowding any one section.

If you're weighing how many panels your home would need, the right number depends on your roof area and your own usage — not just a target offset percentage.

18 panels in West Chester ☀️

We put this array on the steep south-facing roof because it gets the best sun on the property. Each panel has its own microinverter, so if one has an issue, the rest keep producing.

Got a south-facing roof? It might be your best spot for solar.

A 42-panel bifacial array in Lebanon.

Forty-two SEG440 bifacial panels paired with an Enphase microinverter system, sized to deliver a 110% offset against the home's AES usage. Bifacial cells pick up reflected light off the roof surface in addition to direct sun.

The barn's long, open roof planes gave the crew room to run the array across two clean rooflines without crowding vents or hips. Sizing to 110% builds in headroom for usage that grows over time, not just what the panel shows today.

If your property has an outbuilding with a big, unbroken roof like this one, it may carry a larger system more easily than the house itself.

A 20.25 kW system in Bethel, split across two rooflines.

Forty-five REC450 panels on the house and the detached garage, tied together by a 200-foot underground bore run between the two structures. Using both planes meant production from both, instead of crowding everything onto one surface.

That much conduit underground takes careful trenching and splicing to keep line loss down. Our own electricians did that work — not a sub.

If your roof space is split between a house and a detached garage or shop, this is what tying them into one system actually looks like.

A 13.5 kW array in New Richmond.

Thirty REC 450-watt panels with Enphase IQ8 microinverters, set across the south-facing garage roof. Microinverters mean every panel converts on its own — no single inverter that takes the whole system down with it.

The garage was the better plane here. Cleaner exposure, less shading than the steeper house roof behind it, and a shorter conduit run.

If your property has more than one roofline, the right one isn't always the biggest or most visible. It's whichever plane actually sees the sun.

A detach-and-reset in Camp Dennison.

This 5.2 kW array was leaking at the roof — the original install put panels over bad flashing and damaged the electrical components underneath. We took all 16 panels down, replaced the damaged parts, fixed the roof, and set everything back on sound wiring.

Reinstalling over a leaking deck just repeats the failure a few years later. Our own electricians were on the roof, so the bad components got caught before anything went back together.

Seeing leaks or corrosion near your mounts? Worth a look before it gets worse.

Another solar install wrapped up in West Chester Township.

Eighteen panels, all black, sitting clean and flush on the roofline. This system will cover a good chunk of this family's electric bill for the next 25 years — and on sunny days, it'll send extra back to the grid.

Solar is simpler than most people expect. We handle the design, the permits, the utility paperwork and the install. You just watch the meter slow down.

Curious what your roof could do? We'll take a look and give you honest numbers — no pressure, no sales pitch.

Another solid upgrade completed in Mt. Orab! We just wrapped up this electrical service panel replacement, swapping out the home's original Wadsworth 200-amp panel for a new Siemens 200-amp panel — every branch circuit re-landed and torqued onto a new bus, with a modern, correctly rated distribution point for the whole house. Wadsworth breakers are known to fail to trip under overload, which is why these panels get flagged on inspection reports. If your home still has its original panel from decades ago, let the team at Coldstream Power provide a free, no-pressure assessment and honest recommendations. Bringing your electrical up to date may be more within reach than you'd expect — we offer financing options, and you pay nothing until the project is complete!
