Solar Arrays, Explained.

I read a lot of articles out there related to solar energy and I’ve seen many different terms used by authors describing a Photovoltaic Module. Photovoltaic Module, What does it mean? Its just a solar industry term that describes a solar panel that can covert light into electricity. But people often refer to panels as “solar arrays” or “solar cells” and I noticed many people get confused by the different terminology. So lets break it down, The Introduction to Photovoltaic Systems by the infinite power organization of Texas has a great diagram. A group of individual cells make up a solar panel (module) and a group of solar panels create an Array. Typically, people install a solar arrays on their roofs or ground mount solar arrays, rarely solar arrays are mounted to tracking systems to follow the path of the sun. The number of solar panels that make up an array depend on individual project goal, budget and needs. The great aspect of a solar array is that the panels are modular, meaning you can add more panels to the array at a later date to generate more electricity. There are a growing amount of people who are concentrating sunlight onto each solar cell that by magnifying the intensity of the sun and generating a greater output per solar panel, imagine taking a large magnifying glass and putting it over a solar array. Over clocking a solar panel, just like people over clock computer processors for more processing...

Can’t mount solar on your roof? try ground mount.

Solar Photovoltaic Panels that turn sunlight into electricity take up a significant amount of roof space. For every 1 kilowatt of solar you need 100 square feet of southern roof space for solar power to be most cost effective. In the northern hemisphere southern exposure gives you the best return on investment on a solar power system. Many consumers just don’t have the roof space to install solar panels or don’t want to risk the integrity of a new roof by retrofitting solar power. The great aspect of solar panels is that they don’t have to be installed on the roof, they can be mounted on the ground. Typically ground mounted systems are eaiser to clean since they are more accessable, although on the flip side if there is public access on your property, a ground mount system can be exposed to vandalism. The plants, if any around a ground mount must stay trimmed to make sure they don’t end up shading the edges of the ground mounted solar panels. In Germany, where solar panels are very popular and mainstream, ground mounted systems are very common, you can see them everywhere. Obviously a roof top or ground mount systems both have their advantages and disadvantages, you just have to weigh the risks to see which system would fit your individual...

Evergreen Solar ES-A Panels

Last month Evergreen Solar released its ES-A, a new solar panel line. The new panels offered by Evergreen Solar comes in 200, 205 or 210 watt models. There is a trend in the industry right now, we’re seeing more companies release solar panels that are rated over 200 watts. This means you can use less solar panels in a complete solar power system as the output of solar panels continues to increase. The Evergreen Solar team has not only thought about the output of the solar panels but has equipped the ES-A line with quick clickable connectors, which cuts down the time it takes to connect multiple solar panels together to create a solar array. Clickable connectors can make a big difference in cost savings in large commercial installations. Evergreen Solar Panels are manufactured using a string ribbon technology which reduces the carbon footprint in manufacturing Evergreen Solar panels by 50% compared to any other solar panel on the market. Evergreen Solar holds the title of “most environmentally friendly solar panel” in the market, especially compared to Chinese solar panel manufacturers which have been caught dumping manufacturing waste. Evergreen Solar is a US based company with superior quality which makes their products a hot...
