Introduction to Solar Panel Recycling

Introduction to Solar Panel Recycling

With the growing maturity of the commercial solar PV industry, the issue of environment-friendly disposal of old and not-working solar panels and its electronic components is increasingly becoming an important issue and – as part of the emerging electronic waste (e-waste) industry an industry of its own. With increasingly stringent regulations on (electronic) waste treatment […]

Comparing major solar panel test conditions

Comparing major solar panel test conditions

In the PV industry there are various standards and conditions to test the performance and output of solar pv modules. Major test conditions include Normal Operating Cell Temperature (NOCT), PV-USA Test Conditions (PTC), Standard Test Conditions (STC), Low Irradiance Conditions (LIC), High Temperature Conditions (HTC) and Low Temperature Conditions (LTC) whose basics will be explained […]

An introduction to Solar Micro-Inverters

An introduction to Solar Micro-Inverters

In the course of the increasing popularity and sales of micro-inverters even in commercial systems and beyond the U.S. market, the design of photovoltaic (PV) projects and as well the industry are changing dramatically, with solar panel manufacturers already offering integrated “AC” modules equipped with micro-inverters. This article is an introduction to solar micro-inverters, outlining […]

Potential Induced Degradation (PID): an introduction

Potential Induced Degradation (PID): an introduction

In recent years, news about severe quality issues with PV panels have become more and more in quantity. There are increasingly often reports about “mysterious” output yield losses which are linked to potential induced degradation (PID). Even though this problem has been known for years, there have only in recent years been more research studies […]

Introduction to Solar PV Inverter quality testing

Introduction to Solar PV Inverter quality testing

Solar inverters are the operational heart and most defect-sensitive part of every solar PV system. Their basic job is to convert the produced DC voltages of the solar array into maximum usable AC energy and coordinate the efficient and safe operation of the whole array. That said, inverters are required to handle high, varying voltages, […]

Grading of solar cells (A, B, C, D)

Grading of solar cells (A, B, C, D)

Why do manufacturers use lower grade quality solar cells? With solar cells accounting for 60%+ of the solar panel manufacturing costs, solar cells are the number one component used to cut overall costs of a solar panel. No need to say, it’s important to ensure that a pv manufacturer isn’t cutting costs on this precious […]
