Solar PanelsSolar panels convert sunlight into electricity.Sunlight activates the solar cells, whichproduce a direct electrical current (DC).2. InverterThe direct electrical current (DC) is fedthrough an inverter and is converted to analternating current (AC), which can then beused by household appliances.3. Generation MeterGeneration tariff: your energy supplier willpay you a set rate for each unit (or kWh) ofelectricity you generate. Once your system hasbeen registered, the tariff levels are guaranteedfor the period of the tariff (20 years) and areindex-linked.Export tariff: you will get a further paymentfrom your energy supplier for each unit youexport back to the electricity grid, so you cansell any electricity you generate but don’t useyourself. This is estimated as being 50% of theelectricity you generate unless you have anexport meter fitted.sunpowercorp.co.uk 3

SunPower, leading the solar revolution Multi-billion dollar company publicly traded; NASDAQ (SPWR) Based in the United States with headquarters in Silicon Valley Majority shareholder is Total S.A., 25th largest company in the world1 100% focus on solar Celebrating its 30-year anniversary A 25-year warranty covering product and power Over 7 million panels installed across the globe in every climate imaginable1 Source: Forbes 2014 Fortune 2000 Global Ranking.Why SunPower?For over 30 years, SunPower has been deliveringhigh-efficiency solar solutions to homeowners. Whenyou select SunPower panels you can be assured youare getting the most powerful solar systems on themarket2.SunPower panels can dramatically help you reduceyour electricity bill and save money as soon as thesystem is installed.The expression ‘you get what you pay for’ rings verytrue in the solar industry, and with SunPower youare getting the very best solar systems money canbuy.Compared to an investment in conventional solarsystems, an investment in SunPower can delivera much greater return for you and your family, asour panels generate more energy, higher savings,greater reliability and a stronger warranty3.More energy more savingsSunPower technology is able to guarantee an amount of energy production (also known as yield) that issignificantly higher than conventional panels. Higher yield combined with efficiencies that are greater thanconventional cells, translate into greater savings.2 SunPower has the highest efficiency panels, out of all 2600 panels listed in Photon International, Feb 2012.3 Definitions used throughout the document: “Conventional Panel” is a 230W - 250W 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.4 sunpowercorp.co.uk

All SunPower systems arebuilt with fundamentally different Maxeon backcontact solar cells: their unique design captures andconverts more sunlight into electricity, while a solidcopper foundation makes them incredibly durable,guaranteeing long-term performance.With up to 24% efficiency, Maxeon cells produceup to 44% more power over the same area whencompared to conventional solar technologies1.These cells consistently outperform in a broadrange of real world conditions, including hightemperatures, humidity, low light levels and harshclimates.SunPower Maxeon solar cellis fundamentally different solar Patented back contact cell technology Durable copper foundation High efficiency Exceptional performance Incomparable durability1: Comparison between SunPower X-series panels and conventional panel - i.e. a 240W panel, 15% efficient, approx. 1.6 m², made with conventional cells.6 sunpowercorp.co.uk

More energy for your homeSunPower’s high efficiency solar technology is thebest choice for space-constrained rooftops, given itshigher energy production per square metre whichtranslates into greater savings.Built with the Maxeon solar cell, the SunPower E20panel series sets a new standard for solar, achievingover 20% panel efficiency and outstanding energydelivery per watt installed.Long-term reliabilitySunPower technology is manufactured with premium,high-quality materials (anti-reflective glass, ultra-puremonocrystalline silicon, solid copper foundation),guaranteeing decades of reliable performance underall weather conditions.At our laboratories we design tests to simulate reallife conditions and conduct extreme testing to ensurethat our solar energy systems will last and perform asexpected for 25 years.As a result, your solar system will better withstand therigors of life in the field (temperature swings, moisture,humidity and shading), ensuring long-term peace ofmind and an optimal return on your investment.sunpowercorp.co.uk 7

Peace of mind for a minimum of 25 yearsPower warrantyProduct warrantyMany manufacturers offer a 25-year “stepped”warranty, typically guaranteeing 90% power outputfor the 1st 10 years then only 80% for the remaining15 years.Typically a solar panel manufacturer’s warranty isfor 10 years, after that period you are not coveredshould a problem arise.SunPower guarantees over 95% power output for the1st 5 years, then a 0.4% degradation rate each yearfor the next 20 years. After the 25th year SunPowerpanels will be still be producing over 87% of theiroriginal power.SunPower products are backed by a 25-year productwarranty, which covers the full cost of panel removal,shipping and replacement, giving you tyPower warrantyPower warranty100%9.1%95%MORE ENERGYSUNPOWERSUNPOWER90%85%INDUSTRY AVERAGEINDUSTRY STANDARDTRADITIONAL WARRANTY5-10 yearsTRADITIONAL WARRANTY80%75%051015YEARSBest available Conventional Panel „linear“ warranty8 sunpowercorp.co.uk2025051015YEARS2025

Return on investmentUnderstanding the true valueof your solar investmentSystem costs can often be confused with value, whenthe true value of a solar investment should always becalculated over its entire lifetime (25 years plus).Value can be calculated directly from differentvariables that make up a solar system, these includeboth inputs and outputs.INPUTSOUTPUTS System size Number of panels Energy generated by the system Roof area required The value of that energy Panel efficiency System costOutlined below is a comparison between a SunPowersystem and a conventional system.The associated variables are listed and the total valueof the energy generated is clearly highlighted.An investment in solar is a long term economicinvestment (25 years plus): it pays not to takeshortcuts. It is important to ask questions beforeinvesting in a 25-year plus asset, such as:It is clear from the example that a SunPower systemis different, as it requires less panels and roof spaceto generate more energy and value over its lifetime. h ow efficient are the panels? h ow much energy will the system produce over itslifetime? w hat is the product and performance warranty? w ill the product manufacturer still be aroundin 10 or 25 years?The below example is based on a current average residential electricity priceof 0.15p / kWh and using reported future energy increases in the UK.System Variables (All figures based over 25 years)SunPowerPremium PanelsConventionalPanelsPanelsSystem size (kWp)Number of panelsTotal roof area required (m2)Panel effciencykWh generated2Value of energy generated1SunPower energy advantageE20 327W3,9241219,620,1%94,675 32,05814%240W3,8401625,616,0%81,850 27,613 0 500Warranty VariableReplacement cost of an underperforming panel after 10 years1.
