1 More Energy. For Life. Maximise your solar energy production with SunPower.

2 It s the right time to invest in solar World leading solar technology With rising grid electricity prices and declining solar technology costs, more and more leading businesses are enjoying the economic benefits of solar power. Going solar can save money on energy costs today and hedge against rising utility rates tomorrow. However, understanding the true value of any business decision requires that you weigh the total benefit against the total cost of that decision, whether you are upgrading machinery, purchasing land, or installing solar technology. To make a wise assessment on whether to go solar, you need to answer two fundamental questions: 1 How much electricity will my solar installation generate over the lifetime of the system? This is a measure of the total benefit. 2 How does the lifetime cost of the solar electricity produced compare to what you would pay your current provider over that same period? This is a measure of the total cost. More than a quarter of a century of experience Founded in 1985 as a Silicon Valley pioneer Committed to innovation: more than 200 patents registered worldwide Diversified portfolio: residential, commercial and utility-scale power plants Traded on NASDAQ (SPWR) More than 5,000 employees and 1,800 partners More than 7,000,000 panels installed worldwide How solar can benefit your business: Savings Save on your monthly electricity bill Reduce your operating costs For over 25 years, SunPower has been delivering high-efficiency solar solutions 1.

3 Why SunPower technology is different. Why it is better. Superior technology for higher energy output What makes our solar solutions different is our superior technology. All our systems are built around fundamentally different solar cells which use the SunPower Maxeon all-back contact technology. Their unique design captures and converts more sunlight into electricity, while a solid copper foundation makes them incredibly durable, guaranteeing long-term performance. SunPower Maxeon solar cell is fundamentally different Back-contact cell technology With up to 24% efficiency, SunPower panels deliver 36% more power 1 over the same area when compared with Conventional Cells. Our cells consistently outperform in a broad range of real world conditions, including high temperatures, humidity, low light levels and harsh climates. Exceptional performance Technology your business can rely on SunPower Maxeon cells are designed and tested to the highest possible standards to ensure reliability over the lifetime of the product. What makes SunPower Maxeon cells more reliable? The design of SunPower Maxeon solar cells is unique. Each cell is built on a solid copper foundation providing the strength and durability needed to survive all weather conditions year after year. Conversely, Conventional Cells use a low-cost metal paste on the front and back to conduct the power generated by the cell, and are thus vulnerable to failing when exposed to these elements. 86% of Conventional Cells degrade through corrosion or cracking due to temperature fluctuations 1. This causes them to steadily lose power over time or completely fail 1. The unique SunPower Maxeon cells are virtually impervious to these issues. Only 27 out of a million panels have been returned under warranty 2. Durable copper foundation Incomparable durability High efficiency 1 Wohlgemuth, J. Reliability of PV Systems.

4 Why efficiency matters More energy means more savings for your business SunPower panels are fundamentally different and are able The chart below shows the SunPower production advantage to provide an energy yield that is significantly higher than of about 8% (per rated watt) on year one. This is combined Conventional Panels of the same rated watts. with SunPower lower degradation rate to highlight how the energy production advantage grows over time, resulting in Higher yield combined with efficiencies that are higher an average increase of 20% more energy per rated watt at than Conventional Panels translate into greater electricity on year 25. generation and greater savings for you and your business. Different solar technologies yield different energy outputs. Which solar technology you choose dramatically impacts the amount of electricity produced out of your facility s available space. Ideally, you should implement a solution that produces the most energy from the space and resources available. The higher the efficiency of a solar panel, the more power generation capacity it has for any given area. Conventional Panels typically convert only 15% of available sunlight into usable electricity. By selecting panels that exceed this efficiency average, you achieve much higher and faster returns. SunPower panels deliver 36% more power than Conventional Panels¹. The example below outlines an important advantage when installing the most efficient solar panels at your facility to optimise available roof space and maximise energy production. Year-one energy production Same rated watts 1 ENERGY PRODUCTION PER WATT 10% 9% 8% 7% 6% 5% 4% 3% High Power at High Temperatures No Light-Induced hti d Degradation Higher Average Watts Better Low-Light and dspectral Response ENERGY PRODUCTION PER WATT 25-year energy production Same rated watts 2 120% 110% 90% 80% 70% 60% 50% 8% more Year 1 CONVENTIONAL 20% MORE ENERGY 35% more Year 25 High efficiency panels enable more watts to be installed on the available space 2% 1% High-performance Anti-Reflective Glass 0% When comparing SunPower with Conventional Panels Same physical size 3 SunPower = 1 MW 1 Conventional = 735 kw 2 of the same size, the higher efficiency of the SunPower panels creates a huge difference in the energy produced in year one. That energy production advantage grows over a 25-year period to 80% more energy. The chart to the right combines SunPower panel efficiency and its energy production advantage then compares two panels with the same size (different rated watts). ENERGY PRODUCTION PER ROOF 175% 150% 125% 75% 50% 50% more Year 1 CONVENTIONAL 60% MORE ENERGY 80% more Year 25 In this example, approximately 3,060 solar panels are installed on the building: the SunPower system is able to provides 36% more watts from the same available space¹. 1.
