Types of Home Solar Installations

Pitched Roof

Pitched Roof Installations are the most common form of residential solar panel installation. The support components are strong, allowing this system to function successfully in any type of weather condition. Pitched Roof Installations are low-risk and available for just about every type of roof for home solar systems.

Flat Roof

Flat Roof Installations help to accommodate houses with flat roofs. Solar panels are placed tilted up in order to capture the sun’s natural path of progression. The tilted solar panels, and when coupled with our top performing bifacial panels, they can produce up to an additional 10% to 15% backside energy for your solar power system.

Ground Mount

Ground Mount Installations are available for residential properties where the roof isn’t suitable for the placement of solar power system. Solar panels are placed on any form of open land space, and when coupled with our industry-top performing 400 watt bifacial panels, they can produce up to an additional 25% backside energy for your solar power system (up to 500w per panel).

Carport Solar

Carport Mounted Installation serves a dual purpose for the owner, providing shelter as well as producing clean energy for your residential solar property. Our Carport Installation comes in three different options: Cantilever, T-Type, and Custom Structural Steel, and when coupled with our top performing 400 watt bifacial panels, they can produce up to an additional 25% backside energy for your solar panel system (up to 500w per panel).

Trust me, I had my solar installed by another company but Option One Solar's crew were night-and day-different -- no stress and did not bother us at all.

I felt they were reasonable and trustworthy which to me is more important. They worked with me to address any concerns I had and I am happy with the work they have done. I have no problems recommending them as their work is excellent. You get what you pay for.

They were so incredibly helpful every step of the process and were flexible enough to accommodate me when I needed to make changes to the location of our ground-mount array, the configuration, and switching between financing options in the middle of the project. Really great, professional people and company.

Option One installed my system in 2015. I recently had a panel fail and it wasn't under warranty (as the mfr went out of business), but Scott stepped up and his crew took care of it for me.

Called today and spoke with one of your staff members (Esmeralda) she was very nice, patient, friendly, and most importantly very helpful in finding me exactly what I was looking for... She’s definitely the type of employee you want taking your calls.

KC (from Option One) answered most of my questions immediately, and when something came up he couldn't answer, he did the research and got back to me promptly. Off-grid vs on, battery backup alternatives, the extension of the federal subsidy were all issues he helped me with. Even over the holidays, when most offices are not so responsive, Option One was a resource I could turn to.

Knowledgeable, professional, and patient. I ask a lot of questions. Option One explained all the options, helped me calculate the requirements and the cost, and always kept me in the loop. Look no further, if you want an excellent experience for your solar project.

I thought I needed to buy more (panels) to add to My home. Option One took the time to listen to what was going on and instead of them taking Advantage of a Female and selling me more which I didn’t need they told me what I needed to do. They followed up with me and made sure I did it. Thanks Option One, you saved me from spending $35,000 that I didn’t need to.
