Solar Panel Shading: Analysis and Solutions

David Woon · 10 Jun 2021

Solar PV panels work by converting sunlight into DC electricity which then undergoes a DC-AC conversion via an inverter (or multiple micro-inverters) to be used in your household. As the energy generation is dependent on the irradiance or amount of sunlight, it is no surprise that shading is the biggest enemy when it comes to solar PV.

Technologies over the years have dramatically improved to mitigate against the effects of shading, but like with any technology the most appropriate system specification needs to be deployed for a given scenario to yield the greatest benefits.

In the following solar panel shading analysis, we’ll investigate the causes, impacts and solutions for solar PV systems.

Are Premium Solar Inverters Worth It?

George Riley · 27 Jan 2021

It’s something of a solar industry cliche, but the inverter really is the heart of a photovoltaic system. While solar panels harness the sun’s energy, it’s the inverter that converts this direct current (DC) into usable alternating current (AC) electricity. Yet, compared to the panels, inverters rarely get much discussion.

Export Limitation: The Saviour of Large PV Systems?

George Riley · 21 Oct 2020

When in the planning and design stages of a solar PV project, you may come across the term export limitation. Essentially the process involves fitting a device to cap exported power going from the solar system to the grid. But why would you want or need one? Read on to find out...
