Presentation Notes

What makes our solar solutions different is our superior technology. All of our systems are built around SunPower fundamentally different MaxeonTM all-black contact solar cells: their unique design captures and converts more sunlight into electricity, while a solid copper foundation makes them incredibly durable, guaranteeing long-term performance. • Our solar cells can convert more sunlight into more energy than any other system in the world, • Everything is made possible with our superior SunPower® Maxeon® All-Back Contact, High Efficiency Solar Cell technology, which offer the highest efficiency available • Maxeon cells are fundamentally different from the standard solar cells and are built on a solid copper foundation – which not only handles the additional power each cell generates, but also makes it practically immune to the cracking and corrosion that causes standard solar cells to steadily lose power over time • By locating the electrical contacts on the back surface, SunPower achieves conversion efficiencies of up to 24% • The cell design allows for superior performance at higher temperatures and less degradation than other cells, which means more energy is delivered per watt • Which makes our technologies a preferred choice to make the most from the investment in solar For much more detail on Maxeon cell technology, content from the Swagger Module deck can be inserted here.

1 Definitions used throughout presentation: “Conventional Panel” is a 240W panel, 15% efficient, approx. 1.6 m2, made with Conventional Cells. “Conventional Cells” are silicon cells that have many thin metal lines on the front and 2 or 3 interconnect ribbons soldered along the front and back.

• The Maxeon cell has a fundamentally different design from a Conventional Cell: it’s built on a solid copper foundation.

• Copper plated solar cells cost more to manufacture than Conventional Cells, but the investment pays off with a much more reliable and high-performing solar cell.

• SunPower is the only manufacturer with a cell built on a solid copper foundation – the Conventional Cells are made by baking a metal paste onto the silicon wafer – just like screen-printing a logo onto a T-shirt.1

Presentation Notes

The Maxeon Solar Cell is the heart of the SunPower panel. As everyone understands, those cells produce far more energy in the same space. In the example shown here for two panels of the same size, the SunPower 327W and the most common wattage rating for conventional panels: 240W. Also, the front-side is clearly different because there’s no metal grid-lines, and that provides the clean premium look associated with SunPower panels. But the increased power output and the different appearance is not the fundamental difference which justifies the high reliability value of the SunPower panels. That difference is that the Maxeon solar cells are built on a SOLID COPPER FOUNDATION. This is absolutely unique in the solar industry, and in fact it costs SunPower considerably more to build cells on a solid copper foundation – the machines that do the plating process to create this foundation are each a football field in length. The picture on the left shows the front of the Maxeon cell, with no metal at all. The interesting side is actually the back: it’s entirely covered with copper plating. That’s the foundation. In contrast, the picture on the right shows a conventional panel. The metal on the front and back of the cell is not really metal at all – it’s a conductive paste that’s made of tiny bits of silver and aluminum that’s baked onto the silicon wafer. In fact the process of making those cells is the same as screen-printing a design on a tee-shirt: you create a template, wipe the paint across the template and the remove the template to leave the paint where you want it on the tee-shirt, and then bake the tee-shirt to cure the paint onto the fabric. This same screen-printing process is used to apply the thin lines of metal paste on the front, and the full-coverage metal paste on the back, to create a conventional solar cell. But unlike the strength and ductility of the solid copper foundation of the SunPower cell, the metal paste of the conventional cell offers NO strength to the thin silicon wafer, and as we’ll talk about soon, this fundamental design difference drives the big reliability advantages of the SunPower panels.



Maxeon Cell TechnologyDelivers more energy per rated watt

1. Anti-reflective glass captures more energy during cloudy periods and early/late hours

2. N-type Silicon has no Light-Induced Degradation (LID)

3. Backside mirror captures a broader input spectrum

4. Runs cooler (higher efficiency = less heat), and loses efficiency more slowly with heat, and has a lower Normal Cell Operating Temperature (NOCT)

5. Maintains high efficiency at low light levels

Presenter

Presentation Notes

SunPower Maxeon vs conventional solar cells: deliver more energy per rated watt Maximum light capture: capture up to 10% more sunlight Superior temperature performance: generate more energy at higher temperatures Higher voltage and current: convert more photons into electricity No light-induced degradation: do not lose 1-3% of initial power

Presentation Notes

Here’s some proof from independent field testing. For many years, Photon has been running the most comprehensive study of energy production in the solar industry. SunPower previously has not joined this study, because the design differences in SunPower panels make flash-testing them different from conventional panels. Flash-testing is the process by which a light is shone onto the panel, and then the output power is measured to give the panel its rating. SunPower panels are unique in having a copper foundation, and all that metal causes a slower reaction time to the flash test, and labs which do not slow down their flash testing system will not get an accurate rating. At the end of 2011, SunPower and Photon were comfortable that Photon could accurately measure the SunPower panels, and so SunPower joined the test. It has now been almost a full year, and the SunPower panels are generating the most energy per rated watt, ranked #1 out of all the hundreds of panels which are being tested. Taking the performance of the top 10 panel providers, the SunPower panels average 8% more energy per rated watt – in line with the prediction (despite this test happening in Germany, where the high-temperature energy output advantage of SunPower panels doesn’t have as much impact as it would in many warmer sunnier regions). This is powerful 3rd party validation of the 7-9% energy advantage of the E-Series SunPower panels.

Presentation Notes

Because of the durability of the Maxeon cells, and the track-record of low returns and low field degradation, SunPower re-wrote the book on module warranties in 2012. A lifetime warranty: the ultimate protection With SunPower technology, you are assured peace of mind over the long-term. We not only produce the world’s most reliable and highest performing solar systems, we also stand behind them with an unprecedented 25-year combined product and power coverage. This first-of-its-kind warranty ensures 9.1% more energy than the industry standard, effectively securing peace of mind and de-risked return on investments over the 25 years of the system. The SunPower combined power and product warranty guarantees more than 95% of the minimum rated power output for the first 5 years, and then dropping less than 0.4% per year for the next 20 years, so the warranty guarantees more than 87% power output after 25 years of operation. That’s 9% more guaranteed energy over the industry standard warranty, and higher guaranteed power level at 25 years than anyone else in the industry. �In fact, no conventional panel manufacturer can come close to matching this warranty unless they are not worried about their future, since their panels degrade at approximately 1% per year.
