Thanks, Lynn. In the fourth quarter, we recorded the highest NPV per watt in the company’s history and exceeded our cash generation and NPV targets. NPV was $1.22 per watt in Q4, resulting in aggregate NPV created of $91 million, representing 35% growth compared to the prior year. While NPV per watt can fluctuate from quarter-to-quarter given business mix, Q4’s strong results highlight our leading position and our continued focus on managing the business to drive NPV. We are particularly pleased with the unit economics we achieved this quarter, especially as we invest resources in additional product offerings such as Brightbox, grid services initiatives with National Grid and in new market entries. We calculate NPV as project value less creation costs, so let’s go through the components. Q4 project value of $4.52 per watt was $0.03 higher than Q3 and $0.11 higher than last year. As a reminder, project value is very sensitive to modest changes in geographic, channel, and tax equity fund mix. We expect project value will decline slightly over time, but with costs declining more, although in the short run there can be quarterly fluctuations. As Ed will describe, we expect the impact of tax reform to reduce project value by about $0.10 per watt beginning in 2018. Turning now to creation costs on Slide 13. In Q4, total creation costs were $3.30 per watt, an improvement of $0.11 year-over-year. Similar to project value, creation costs can fluctuate quarter-to-quarter due to changes in geographic and channel mix. As a reminder, our cost stack is not directly comparable to those of peers because of our channel partner business. Blended installation cost per watt, which includes the cost of solar projects deployed by our channel partners, as well as installation costs incurred for Sunrun built systems, improved by $0.10 or 4% year-over-year to $2.61 per watt. Install costs for systems built by Sunrun were $1.85 per watt, reflecting a $0.19 or 9% year-over-year improvement. Sunrun built installation costs increased modestly from Q3, owing primarily to higher mixes and strategic growth areas, including our Brightbox solution and new markets which tend to initially have higher costs over a few quarters while we are scaling. We expect total installation costs to show modest declines by the end of the year even with the module tariff impact and as we continue to invest in new geographies and grid services. We also expect the attachment rate of home batteries to continue to increase, which carries a higher per watt cost, but also delivers higher NPV. In Q4, our sales and marketing costs were $0.53 per watt, an 8% improvement from the prior year, driven by channel mix and our focus on the most cost effective customer acquisition channels. For the full year 2017, G&A costs were $0.30 per watt, flat compared to 2016. We expect to realize further operating leverage in the long-term with volume growth exceeding G&A cost increases over time although there can be quarterly fluctuations. Finally, when we calculate creation costs, we subtract the GAAP gross margin contribution realized from our platform services. This includes our distribution, racking, and lead generation businesses as well as solar systems we sell for cash or with a third-party loan. We achieved platform services gross margin of $0.15 per watt, flat with the prior quarter and prior year. In the fourth quarter, deployments increased 10% year-over-year to 85 megawatts. For the full year, we deployed 323 megawatts, 1% below our guidance of 325 megawatts. There were several factors that influenced this, most notably the natural disasters in California during Q4. The fires in both Northern and Southern California not only disrupted the specific areas affected by the fires, but also caused extremely poor air quality conditions for the broader region. The safety of our crews is paramount and we did not want our crews from the 6 affected branches installing during unhealthy conditions. I think this was absolutely the right call for us and many of our partners to make. We did our best to try to make up this gap later in the quarter and in other geographies, but we were unable to fully mitigate the impact. Our cash and third-party loan mix was 13% in Q4, in line with recent levels and the prior year and consistent with our outlook of low to mid-teens. Turning now to our balance sheet, our liquidity position remains strong. We ended Q4 with $242 million in total cash, including restricted and unrestricted cash, the tenth consecutive quarter we have been above $200 million. We generated $43 million in total cash in 2017 on a normalized basis, exceeding our target of $40 million. This excludes about $20 million in accelerated inventory purchases as a partial hedge for the module tariff, along with the $9 million payment in Q2 for the lead-generation business we acquired in 2015, as I mentioned on the last call. We define cash generation as the change in our total cash balance after subtracting the change in our working capital recourse debt facility. We estimate our cash generation will grow materially faster than our deployments in 2018. As the year progresses we will be in a better position to be more specific with our cash generation and net earning asset outlook. Also please note that our cash generation outlook excludes any strategic opportunities or accelerated market entries beyond our current plan. Ed will discuss our capital structure strategy in more detail later on this call. Moving on to guidance on Slide 15, we remain confident in our growth trajectory and are guiding to 15% deployment growth for the full year. In Q1, we expect to deploy 67 megawatts, consistent with the historical seasonal patterns in our business and driven by some market-specific timing. As we pointed out over the last few quarters, we saw strong demand in Arizona ahead of policy changes, which caused some demand pull-in that results in tougher sequential and year-over-year comparisons in early 2018. This means beyond Q1 MWs deployed will grow at about 20% and we expect to approach that number in Q2 with a slightly stronger second half. We are also focusing on our direct business, which is the platform behind the Comcast partnership volume ramp and where we have focused our Brightbox sales and installation efforts and both will be larger contributors in the second half of the year. The increased adoption of Brightbox is exciting given the additional customer value propositions and differentiation, but as markets launch, it also carries longer cycle times. As I mentioned earlier, despite the headwinds from tax reform and the import tariffs, we expect to maintain our unit economics at or above our target of $1 per watt of NPV for the full year, testament to Sunrun’s competitive position, operational and NPV discipline, investment in advanced products and strong financial market execution. Now, let me turn it over to Ed.
