The cost of a solar PV module make up the largest part of the total investment costs. As per the recent analysis of Solar Power Generation Costs in Japan 2021, module unit prices fell sharply. In 2018, the average price was close to 60,000 yen/kW, but by 2021 it is estimated at 30,000 yen/kW, so cost is reduced by almost half.
As of 2012 petrol in Saudi Arabia was sold at a price cheaper than bottled water—approximately US$0.13 per litre ($0.50 per US gallon). [16] According to Jim Krane, "Saudi Arabia now consumes more oil than Germany, an industrialized country with triple the population and an economy nearly five times as large."
The price of a solar array only continues to fall. Average pricing information divides in three pricing categories: those buying small quantities (modules of all sizes in the kilowatt range annually), mid-range buyers (typically up to 10 MWp annually), and large quantity buyers (self-explanatory—and with access to the lowest prices).
A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.

Internal view of a solar inverter. Note the many large capacitors (blue cylinders), used to buffer the double line frequency ripple arising due to single-phase ac system.. A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be ...
The Fraunhofer Institute defines the 'learning rate' as the drop in prices as the cumulative production doubles, some 25% between 1980 and 2010. Although the prices for modules have dropped quickly, current inverter prices have dropped at a much lower rate, and in 2019 constitute over 61% of the cost per kWp, from a quarter in the early 2000s.

However, the percentage of Saudi Arabian citizens who are Christians is zero de jure, [29] as Saudi Arabia forbids religious conversion from Islam and punishes it by death. [ 13 ] [ 30 ] In 2022, the number of Christians living in Saudi Arabia was estimated at 2.1 million; however, it was unknown how many are Protestants, Catholics or Orthodox ...
