Our Story

Built to fix what's broken.
Built to do it right.

HelloSun exists because the solar industry failed. Pennsylvania homeowners and businesses deserve better. We built the company we wanted to exist.

Why We Exist

The solar industry grew fast.
Not always right.

Solar panels work. But the industry hasn't. Most "solar companies" are really sales organizations—sales reps who get paid commissions to close deals and hand your project to the cheapest installer. The results? Poor work, unhappy customers, inflated projections, and a company that's gone before you can react. Accountability doesn't matter when the business model is about the sale, not the customer.

We built HelloSun to be the opposite. We're built on truth. We'll give you real numbers. If your property isn't a good fit, we say so. We won't sacrifice integrity to close a deal. Our mission is real energy infrastructure—and standing behind our work long after install. No inflated promises. No pressure. No disappearing act.

Our Background

Built from service,
skill, and purpose.

Keith Sowell, Founder of HelloSun Energy

I'm Keith Sowell, founder of HelloSun. I'm a U.S. Marine Corps veteran and Pennsylvania Army National Guard member. My military career took me into aerospace and aviation — environments where quality procedures aren't suggestions and checklists exist for a reason. When something fails, there is no ambiguity about who is responsible. That's the standard I grew up in professionally, and it's the only one I know how to operate by.

After aviation, I spent years in the roofing and solar industry. That experience gave me a ground-level understanding of how roof and solar systems are actually built — and where most solar companies create problems they never come back to fix.

I started HelloSun because I saw that the issues in the solar industry weren't caused by the technology, they were institutional. Solar technology really works and actually helps people when it's done the right way. HelloSun was built for that purpose. We are not a high-volume sales organization. We're an energy infrastructure company. We sell it, we design it, we install it, and we stand behind it. Our mission is simple: to give you choice, control, and a system that performs for decades. We don't measure success by how many deals we close. We measure it by how well our systems perform — and how well we serve the families who trust us.

How We Operate

The HelloSun Standard

Our focus is simple: cut energy costs for customers and create real, lasting value. Solar isn't a gimmick—it's an investment. We treat it that way. Our goal is turning customers into lifelong advocates.

📐

Engineering-First Design

Every system is engineered for your specific property—roof geometry, shading, load profile, utility rates. No templates, no guessing.

🔧

Trusted Local Professionals

Every install uses vetted local professionals who know PA utilities, codes, and interconnection rules. No out-of-state crews, no unknowns.

📊

Transparent Proposals

Real production estimates based on actual data. We'd rather show you conservative numbers that hold up than inflated ones that disappoint later.

📞

We're Here After the Install

Clear communication, responsive support, and standing behind our work long after your system turns on. The relationship doesn't end at commissioning.

What Our Customers Say

Real feedback from real customers.

★★★★★

"The signup process was easy, I had to print my electric bill but it only took maybe 15 minutes? Keith was upfront with us from the very first visit. No pressure at all, he told us exactly what to expect and delivered on every promise, a wealth of knowledge. The system has been running flawlessly and our electric bill is basically gone except the Met-Ed customer charge. Wish we'd done it three years ago."

Michael T. Mohnton, PA
★★★★★

"We got four quotes. Three of the companies were pushing a leased system, the reps were obviously new or untrained, one wouldn't even give us a cash price. HelloSun was different entirely... very professional, honest, and informative. They were actually able to answer questions. They were our final quote, and not the highest!"

Dave & Linda R. Doylestown, PA
★★★★★

"Keith's team did our solar. You could tell these guys actually knew what they were doing, job was done in two days and looks AMAZING. Had one minor hiccup during the install, they had the part replaced two days later in the rain while I held the umbrella lol. That kind of service is rare."

Jennifer M. Annville, PA
★★★★★

"We were skeptical about doing solar because our friend got scammed by some New Jersey company. HelloSun walked us through everything, the system turned out exactly the way we wanted. Eight months in the system is performing above the estimate. We've already referred two neighbors and both of them went with HelloSun too. A++"
