Are back contact solar panels better?

Solar Panels

Not all solar systems are created equal. Of all the solar panels on the market, back contact panels convert more sunlight into electricity—generating more energy than conventional panels within the same amount of space. With back contact panels you can maximise the value of your available roof space and reduce electricity costs over time.

Are solar panels worth it?

Solar Panels

Solar panels can be a worthwhile investment, especially in regions with abundant sunlight and favorable incentives. They offer numerous benefits, including cost savings on electricity bills, reduced environmental impact, and potential increases in property value. Solar panels typically pay for themselves over time through energy savings and potential government incentives, making them an attractive option for many homeowners and businesses interested in sustainable energy solutions and long-term financial benefits. The return on investment, however depends on factors like your energy consumption, location, available incentives, and long-term goals. That's why we recommend to conduct a thorough evaluation and consult with one of our solar professionals to determine the specific economic and environmental advantages for your situation.

Are there ways to increase albedo?

Solar Panels

In the market there are certain products that apply to the surface of the roof or ground that are intended to increase the reflectivity. This could be a white polymer coating or light-colored gravel for example. Pricing varies based on the material and labor costs. Customers should work with their installation partners to understand available options for increasing the surface albedo under their arrays.

Are yield advantages reflected in simulation tools such as PV Syst?

Tips

Yes, we have guidelines we can share to allow you to set PV Syst using our 3rd-party-validated PAN files. Third party validation from Dekra or SGS allow customers to have more confidence in what they are purchasing and better estimate of return on investment and LCOE (levelized cost of electricity).

Do bifacial panels provide additional advantages for floating PV systems?

Solar Panels

Possibly. The glass/glass framed construction of the bifacial panel provides additional resistance to water and salt ingress. However, careful analysis should be undertaken to evaluate variables such as panel tilt and elevation that may require stronger mounting BOS requirements to gain the full advantage of bifacial panels. It should be noted that floating PV is not currently covered under TCL | SunPower warranty. This should be approved on a project base.

Does Cosmetic quality affect the panel’s performance?

Solar Panels

Every single panel is electrically tested and inspected for cosmetic criteria at the end of the production line. Regardless of the cosmetic grade, the cosmetic effects do not affect performance or reliability.

Does my installer have to be a SunPower partner?

Cash Back

No. If there are no SunPower Partners in your area, we will pair you with a qualified installer, or you can appoint an installer of your choice.

Does the end customer receive confirmation of its 40-year warranty?

Warranty

At the end of the registration process, the end customer will receive an email confirming the registration of its warranty and recapping all registration and product data. This confirmation email is proof of warranty certification.

How are shingled TOPCon panels different from standard TOPCon panels?

Solar Panels

Shingled technology represents an evolution in solar panel design, combining N-type TOPCon solar cells with an innovative cell design to maximize efficiency, reliability, and real-world performance. In shingled technology, TOPCon solar cells are cut into smaller 1/3 strips and electrically connected in a shingled, overlapping configuration. This design eliminates inactive gaps between cells, increasing energy production and boosting overall panel output. Shingled TOPCon provides a premium solution, offering higher performance and enhanced reliability, particularly beneficial for installations with limited roof space or complex shading challenges.
