Edison invented direct current, which continuously flows in a single direction, as in a battery or fuel cell. Direct current (abbreviated as DC) was the standard in the United States throughout the early days of electricity. However, there was a snag. It is challenging to convert direct current to higher or lower voltages. Tesla believed that the solution to this problem was alternating current (or AC). A transformer can readily convert alternating electricity to different voltages because it reverses direction a specific number of times per second (60 in the United States). Edison initiated a campaign to denigrate alternating current to protect the royalties he was getting from his direct current patents. He circulated false information about alternating current being more deadly, even going so far as to publicly electrocute stray animals to establish his point (Lantero 2014).<\/p><p>The World\u2019s Fair in Chicago, commonly known as the World\u2019s Columbian Exposition, was held in 1893, during the height of the Civil War. General Electric bid $554,000 to electrify the fair using Tesla\u2019s alternating current for only $399,000. The Niagara Falls Power Company opted to award the contract to generate power from Niagara Falls to Westinghouse, licensed Tesla\u2019s polyphase AC induction motor patent. Although others questioned whether the falls could power the entire city of Buffalo, New York, Tesla was confident that they could power Buffalo and the whole of Eastern United States. The alternating current from Niagara Falls lit up Buffalo on Nov 16, 1986. General Electric had also decided to join the alternating current train (Lantero 2014).<\/p><p>Although it appears that alternating current has nearly decimated direct current, the direct current has seen a resurgence in recent years. Today, our electricity is still primarily alternating current, although computers, LEDs, solar cells, and electric cars all use direct current. And technologies for converting direct current to greater and lower voltages are now accessible. Companies are developing ways to use high voltage direct current (HVDC) to carry electricity over great distances with less electrical loss since the direct current is more stable. As a result, it looks that the War of Currents is far from over. Rather than continuing the intense AC vs. DC struggle, it appears that the two currents will end up functioning in parallel in a hybrid armistice. None of this would have been feasible without Tesla and Edison\u2019s brilliance (Lantero 2014).<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-84bbfb7 elementor-widget elementor-widget-spacer\" data-id=\"84bbfb7\" data-element_type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c473459 elementor-widget elementor-widget-heading\" data-id=\"c473459\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">1.0 Background<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ef41195 elementor-widget elementor-widget-heading\" data-id=\"ef41195\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">1.1\tWhat is AC?<\/h4>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-73cef13 elementor-widget elementor-widget-text-editor\" data-id=\"73cef13\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>The flow of electric charge that periodically reverses is known as alternating current, or AC. It starts at zero, increases to a maximum, declines to zero, reverses, reaches a maximum in the opposite direction, returns to the original value, and repeats this cycle indefinitely. The period is the time interval between the attainment of a specific value on two consecutive cycles. The frequency is the number of cycles or periods per second. The amplitude of the alternating current is the highest value in either direction. Low frequencies, such as 50 and 60 cycles per second (hertz), are used for domestic and commercial power, but alternating currents of frequencies around 100,000,000 cycles per second (100 megahertz) are used in television and several thousand megahertz in radar and microwave communication. The frequencies used by cellular phones are around 1,000 megahertz (1 gigahertz).<\/p><p>For decades, alternating current (AC) had the unique advantage over direct current (DC; a constant flow of electric charge in one direction). Due to resistance, it could transport power over long distances with minor energy loss. The power communicated is equal to the current multiplied by the voltage, while the power lost equals the resistance multiplied by the current squared (Britannica n.d.).<\/p><p>AC modules are primarily used on rooftops and buildings in Europe. As a result, the cost of repair will be significant. Furthermore, the PV module houses most of the inverters. As a result, it\u2019s critical that the inverters have a lifespan equivalent to that of the PV modules, which can last up to 20 years.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d9a4e3e elementor-widget elementor-widget-heading\" data-id=\"d9a4e3e\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">1.2\tAC Modules<\/h4>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a389148 elementor-widget elementor-widget-text-editor\" data-id=\"a389148\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Unlike traditional photovoltaic systems with a single central inverter, AC modules provide numerous benefits.

The software will be improved and made more user-friendly, and low-cost monitoring displays with fault indication and diagnostics will eventually replace it (Jong 1998).<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b52c120 elementor-widget elementor-widget-heading\" data-id=\"b52c120\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">1.6 \tMaxeon 5 AC module \t<\/h4>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-44b1b9d elementor-widget elementor-widget-text-editor\" data-id=\"44b1b9d\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>For the Maxeon 5 AC Module, there is an integrated microinverter at every module. If the microinverter (or the related PV module) fails, only that PV module is turned off. The rest of the system continues to function normally \u2013 a significant advantage of AC modules. Unlike conventional solar modules like DC panels. The solar array\u2019s output is controlled by a single inverter, creating a design with a single point of failure. Moreover, each Maxeon 5 AC module is self-contained, ensuring that your entire system is more reliable and your rooftop is more productive. The system only performs as well as its weakest panel when using traditional technologies due to shadow or other real-world difficulties, such as tiny particles like leaves (Technologies n.d.)<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2b01da5 elementor-widget elementor-widget-heading\" data-id=\"2b01da5\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">2.0\tWhat is DC? <\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0fb6b14 elementor-widget elementor-widget-text-editor\" data-id=\"0fb6b14\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>DC stands for direct current, an electric charge flow that does not change direction. Batteries, fuel cells, rectifiers, and generators with commutators all produce direct current. Because it was uneconomical to adapt direct current to the high voltages required for long-distance transmission in the late 1880s. It was replaced by an alternating current (AC) for standard commercial electricity. Direct current is now transferred over very long distances, even though it must normally be converted to alternating current for final distribution, thanks to techniques established in the 1960s (Britannica n.d.).<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-590e0b3 elementor-widget elementor-widget-heading\" data-id=\"590e0b3\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">2.1 \tWhy DC solar module?<\/h4>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c7d6bc4 elementor-widget elementor-widget-text-editor\" data-id=\"c7d6bc4\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>DC Solar modules are still heavily reliable due to their ease of storing energy into batteries (DC). Why can\u2019t we store AC in batteries? Well, because AC changes polarity up to 50 (when frequency = 50Hz) or 60 (when frequency = 60Hz) times per second, we can\u2019t store it in batteries. As a result, the battery terminals change, i.e., Positive (+ve) becomes Negative (-ve) and vice versa; however, the battery terminals cannot change at the same rate, which is why we can\u2019t store AC in batteries\u00a0(Technology n.d.).<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-38f0396 elementor-widget elementor-widget-heading\" data-id=\"38f0396\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">3.0\tWhich is best for you?<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-dbbd7ca elementor-widget elementor-widget-text-editor\" data-id=\"dbbd7ca\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>For customers who only want to install a solar panel, it is recommended that they go with AC solar modules. But, when it comes to installing a solar panel and a battery, opting for an AC solar module is probably not a wise option. The drawbacks of the AC solar module are that they can\u2019t store energy in batteries. This fact might be a huge blow for one, but the benefits of the AC solar module overshadow the DC solar module in terms of labour, maintenance, warranty, and power quality. Although AC solar modules are expensive and cost more due to the integrated micro-inverter, they are easier to install and require less labour.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4d5c803 elementor-widget elementor-widget-heading\" data-id=\"4d5c803\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">4.0\tBibliography<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b12e7b2 elementor-widget elementor-widget-text-editor\" data-id=\"b12e7b2\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<ul><li>Britannica, The Editors of Encyclopaedia. n.d. \u201cAlternating current .\u201d <em><i>Britannica|Electronics.<\/i><\/em><\/li><li>Jong, H.Oldenkamp and I.J de. 1998. \u201cAC modules: past present and future .\u201d <em><i>Workshop Installing the Solar Solution .<\/i><\/em><\/li><li>Lantero, Allison. 2014. \u201cThe War of the Currents :AC vs DC Power.\u201d <em><i>Gov.<\/i><\/em>18 November .
