Challenges in solar power generation

One of the most promising renewable energy technologies is solar power which allows generating electricity from free, unlimited sunlight. It’s one of the rapid growth industry and technology which contributes significantly to homeowners and commercial industry. It would be a reasonable and useful solution for new power generation installations in developing countries to be powered by carbon emission free sources like solar.  Solar seems perfect for countries with lots of sun exposure and no efficient way of bringing the conventional power grid to remote locations.  But solar still faces a number of obstacles before it can really replace fossil fuels for power generation. However, there are many unexpected challenges with solar electrification that entrepreneurs are learning about while doing business in these developing countries. The Levelized Cost of Solar PowerLevelized cost of Solar Power is a term which describes the cost of the power produced by solar over a period o

How solar panels are made

A solar PV module contains solar cells, glass, EVA, back sheet and frame.Three types of solar panels are available in the market. They are:    Mono-crystalline solar panels    Poly-crystalline solar panels    Thin film solar panelsTherefore, various types of materials are used for manufacturing at cell structure level. They are - mono silicon, poly silicon or amorphous silicon. Mono and Poly crystalline cells have almost similar manufacturing process. For producing a crystalline solar panel following steps are followed:First Step: SandHere sands are used as a raw material. Most solar panels are made of silicon, which is the main component in natural beach sand. Silicon is plentifully available which is the second most available element on Earth. However, converting sand into high grade silicon is a high cost energy intensive process. Pure silicon is produced from quartz sand in an arc furnace at very high temperatures.Second Step: IngotsBasically, the silicon is collected in the form o

How to install solar panels

In order to generate electricity for both commercial and home use, solar panels are used. For getting maximum possible sunlight and generate maximum electricity from the system, photovoltaic panels are installed on the roof top in both cases. Following steps are followed in the installation process:First Step: Installing Mounting Structures of Solar PanelsIn the first step, the mounts are required to be fixed for supporting the solar panels. It can be Roof-ground mounts or flush mounts which dependent on the requirement. This base structure provides support and strength.  Precaution is taken on direction in which the PV panels (mono crystalline or poly crystalline) will be installed. The best direction to face solar panels is south for countries in the Northern Hemisphere because it gets maximum sunlight. East and West directions will also do. On the other hand, the best direction is north for countries in the Southern Hemisphere. The mounting structure needs to be slightly tilted. Ang
