Given a 5 kW system and $400 estimated truck roll cost, even 5-percent failure rate will exposes installers to $400,000 in service costs within the first year of operation, given 1,000 installs that year. This number grows exponentially over the life of those systems. For installers with less volume (10-15 systems per month), annual service costs can still reach $14,000 for failed module-level components. At the end of 10 years, those truck roll costs amount to $4,000,000 and $120,000, respectively.<\/p>\n<h5><strong>Increased uptime with SMA, all the time<\/strong><\/h5>\n<p>Significantly lower failure rates are not the only contributing factor to SMA\u2019s unparalleled system uptime. Should issues arise, SMA ships replacement inverters within 24 hours of the service call, often the same day, while competitors only guarantee a new device within 48 hours of the old one being received at their service center.<\/p>\n<h5><strong>All five parts<\/strong><\/h5>\n<p>Miss any of the other four parts of this series? <a href=\"http:\/\/www.smainverted.com\/2015\/08\/06\/part-1-how-does-the-sunny-boy-tl-us-stack-up-against-module-level-systems\/\">Part 1<\/a> explored the added value of the Sunny Boy TL-US with Secure Power Supply while <a href=\"http:\/\/www.smainverted.com\/2015\/08\/11\/part-2-how-does-the-sunny-boy-tl-us-stack-up-against-module-level-systems\/\">Part 2<\/a> discussed the additional labor costs associated with module-level power electronics. <a href=\"http:\/\/www.smainverted.com\/2015\/08\/25\/part-3-how-does-the-sunny-boy-tl-us-stack-up-against-module-level-systems\/\">Part 3<\/a> and <a href=\"http:\/\/www.smainverted.com\/2015\/09\/08\/part-4-how-does-the-sunny-boy-tl-us-stack-up-against-module-level-systems\/\">Part 4<\/a> compared shade mitigation technology and system costs of module-level power electronics and the Sunny Boy TL-US with Secure Power Supply, respectively.<\/p>\n<p>Still looking for more information on why the Sunny Boy TL-US with Secure Power Supply is quickly becoming the most popular residential PV solution?
