The price of solar power plants has dropped significantly in recent years, as solar power plants are on the rise. And the data shows that the price decline is unlikely to slow in the near term. In 2015, the price of residential systems fell 5% and 12% for larger scale solar farms.
The Lawrence Berkeley National Laboratory reports, Follow the sun Yes Solar Utility Scale 2015, show that in any installation, solar energy has reduced its costs considerably since 2010. Large solar installations have decreased the most.
According to the report Follow the sun, the average prices of distributed solar PV systems fell by $ 0.20 per watt (5%) from the previous year for residential PV systems, while small non-residential systems fell by 0.30 $ per watt (7%). ) and $ 0.30 (9%) for large installations.
The installation cost includes everything you need to run a solar power system: the panels, power electronics, mounting hardware, and the installation itself.
The continued decline in the total installation is notable considering the fact that the price of solar panels (or modules) has remained relatively stable since 2012. This means that the decline in the installation price observed since 2012, This has been largely part caused by a decrease in the cost of inverters that convert the direct current produced by the solar panels into alternating current for the grid.
Both reports They also point out that while the average price of solar energy has fallen, there are differences between residential installations and large solar farms. Large-scale solar electricity is around 50% cheaper than at the residential level.
The Berkeley Lab report also documents the drop in net solar power prices. Lower installed project costs and higher capacity factors have lowered power purchase agreement (PPA) prices for commercial scale projects by an average of $ 20 to $ 30 per year from 2006 to 2013. As a result, in 2015, most PPAs were valued at $ 50 or less per megawatt hour, and a few at around $ 30 / MWh.
The biggest drop is for large-scale installations, where the price has fallen 12% to an average of just over $ 2 per watt. The report estimates that the prices of power purchase contracts for commercial scale projects fell by $ 20 to $ 30 per year between 2006 and 2013 on average.
Average project capacity factors have also improved over the past four years, from 21% in 2010 to almost 27% in 2014.
From now on, the price of solar energy will continue to fall in all its categories, according to the latest report from the Lawrence Berkeley National Laboratory. Investing in renewable energy by 2019 will lead us to continued expansion of the solar market in the United States.
