![]() ![]() If you split a string of panels on your roof so that half face south and half face east, the south-facing panels will drop to the lower output of the panels that face to the east. In the US, panels should face south for optimal production. Panel Facing. Panels produce the most energy when they face directly at the sun.Shade. Your panel will produce less energy when it’s shaded, and shading on one panel will impact the entire string.Here are some factors that can cause this drop in production: When one panel in the string suffers reduced output, every panel in the string drops to that reduced output.įor example, you may have 330W panels, but if a single panel in the string falls to 250W production, every panel in that string is going to produce 250W of power. They are ideal for both residential and commercial properties without shading issues and can be paired with power optimizers.Ĭons: You’ve probably heard the saying “a chain is only as strong as its weakest link.” That principle applies to panel strings. Pros: String inverters are the most cost-effective option available. string inverter, pay careful attention to the differences and what inverter makes sense for you, weighing the pros and cons. If you are considering upgrading to a power optimizer or micro-inverter vs. Micro-inverters and power optimizers offer similar benefits but operate in different ways, best suited for roofs that have shading or are oriented in different directions. String inverters are generally the most common and affordable inverter option and function best if your roof has plenty of exposure to sunlight. SolarEdge HD-Wave optimizers on the back of an array of solar panels. If a single panel under-produces due to shade or malfunction, optimizers ensure the other panels in the string are not affected. a micro-inverter is that it solves the limitations of string inverters. The difference between a power optimizer vs. Optimizers can be attached to your solar panels, enabling you to control each panel’s output independently from the rest of the string. Enphase micro-inverters mounted on the back of solar panels. ![]() Instead, each panel is hooked up to its own micro-inverter. a central inverter is that in micro-inverter systems, there is no centralized inverter. The difference between a micro-inverter vs. What is a micro-inverter?Ī micro-inverter is an inverter that pairs with a single solar panel to manage the DC-to-AC power inversion for that individual panel.

Here’s a breakdown of the different types of solar inverters to help you find the right solution for your solar installation. Solar inverters are an essential part of any solar PV installation understanding the difference can help you select the right converter and save you money. Solar Inverters: What Are the Differences? Our goal is to provide an entry-level primer that compares pricing, pros and cons, and ideal applications for each type of solar inverter. This article will break down the three main types of inverters used for solar: string inverters vs. ![]() The inverter’s role in your system is to convert DC to AC so that the energy generated by your panels can be used to power your appliances. Solar panels generate direct current from the sun, but most home appliances run on alternating current. Polycrystalline Solar PanelsĪ solar inverter converts DC (direct current) into AC ( alternating current).
