We protect your roof. Guaranteed.


Your solar journey begins with a detailed analysis of your current energy consumption. From there, we craft a 3D model of your home. Our design engineers rely on 20 years of sun positioning data to ensure that your solar system is perfectly calibrated to generate the electricity your household needs.

With MARCOR®, your custom designed solar system guarantees substantial savings, and provides you with a uniquely tailored system that perfectly aligns with your home and lifestyle.

Cutting Edge Design


Choosing the right panel is an important decision—after all, they’ll be on your roof for many decades to come. Qcells® are high-quality monocrystalline silicon solar panels that offer high efficiency and performance. With Qcells®, you can be confident you’ll enjoy years of savings over the lifetime of your solar system.

Qcells® Solar Panels


QCells also features “Zero-Gap” Technology, which means gaps between the cells are closed to ensure a more effective use of the module area. By reducing the space between the cells, module efficiency is increased. QCells® solar modules offer up to 18.5% more power and thus higher production yields.

Zero Gap Technology
Q.ANTUM Technology


QCell’s Q.ANTUM Technology enables the back of the QCell panel to capture light and create energy. Rays of sunlight that would otherwise go to waste are reflected back through the cell to generate more electricity. This helps your panels be as efficient as possible, even in low light or on high-heat days.

Waterproof Mounting that Safeguards Your Roof

The most crucial element of any solar installation is its connection to your roof. At MARCOR®, safeguarding your roof is our top priority. That's why we utilize the RT-Apex, a minimally invasive and fully waterproof mounting bracket, to ensure the security and integrity of your roof. With a MARCOR® installation, you can be confident you’re getting the most minimally invasive, watertight solar connection available.

Alpha-Seal™ Technology is what sets the RT-Apex apart from traditional solar mounting systems. The flashing underneath each mount has superior flexibility and is completely impermeable to moisture. This waterproof, adhesive seal makes installation much less invasive than traditional mounting systems and virtually eliminates the risk of water infiltration.

Waterproof AlphSeal® Technology

The RT-Apex is a rail-free solar mount. Rail-free mounting systems weigh significantly less than their rail-based counterparts, and offer a more balanced weight distribution across the roof area. This minimizes stress on your roof’s structure. Moreover, the RT-Apex is engineered to withstand wind speeds up to 180 mph and ground snow up to 90 PSF.

Minimally Invasive Mounting

The IQ8+ is installed under individual solar panels, allowing each panel to operate at its maximum potential. In contrast, string inverters are connected to multiple panels in a series, and the performance of the entire string can be affected by the weakest panel. Moreover, the IQ8+ mitigates the impact of shading or soiling on individual panels. When one panel is shaded or dirty, it doesn't affect the performance of the entire array, as it would with string inverters.

The Enphase IQ8+ Microinverter stands out as the best microinverter available due to its innovative "grid-forming" technology, which enables it to function independently during grid outages, providing uninterrupted power to the connected building. Moreover, the IQ8+ offers superior control and flexibility over solar energy production and consumption, allowing homeowners to maximize their solar investment and reduce reliance on the grid while contributing to a more sustainable and resilient energy future.

Real-Time Monitoring

ENPHASE IQ8 Microinverter

The IQ8+ provides homeowners with real-time monitoring and control capabilities, enabling them to track energy production, consumption, and system performance through user-friendly interfaces.

We're Trusted by Long Island Homeowners

Amazing! Marcor Solar replaced my roof and installed a large, 49-panel solar system on my house in Long Island, and I couldn't be happier. The workmanship of both the roof installation and solar installation was impeccable. My electric bills have been reduced to almost nothing. I'd recommend that anyone looking to have solar installed reach out to Marcor.

— Gregory H.

"The workmanship was impeccable"

They were very detailed in every step and not only kept me informed but also answered all my questions. From the beginning it was clear that this company doesn't treat the job as a 'quick' installation and takes the time to go the extra mile to make the customer happy. I highly recommend Marcor Construction Solar Installations.

— Vince C.

"I highly recommend Marcor Solar"

My solar needed some repair and the previous company was no longer in existence. I reached out to Marcor and am so happy I did. Dave was able to get me started right away when other companies were turning me away. Wilson the technician that helped us was PHENOMENAL!!! Amazing people, great quality of work, couldn't ask for more.
