STC stands for “Standard Test Conditions” and are the industry standard for the conditions under which a solar panel are tested. By using a fixed set of conditions, all solar panels can be more accurately compared and rated against each other. There are three standard test conditions which are: 1. Temperature of the cell - 25°C. The temperature of the solar cell itself, not the temperature of the surrounding. 2. Solar Irradiance - 1000 Watts per square meter. This number refers to...
A solar panel is actually just a casing that holds multiple small solar cells. These are the blue or dark-blue squares inside the solar panel that are actually absorbing the light and producing the energy. Each individual cell has its own voltage and amperage that are normally both very small. By combining these small cells together, the voltage and amperage can be combined into the larger output which is what the entire solar panel is rated for. Connecting cells in...
A big Yes! The Department of Education calls the amount the US produces their own oil, Field Production. Statistics have shown that the total percentage of field production in the US will decrease and the total percentage of dependence on oil imports will increase in the years to come. For example in the year 2000 the US had in Field Production only about 35 percent of its oil, but 5 years later the number has decreased to 28 percent. Along with this rate,...
Though light bulbs have traditionally been measured in Watts, today, manufacturer are now required to provide Lumens on the packaging for lights. Watts is the measurement of how much energy the light bulb will draw. However, this really has nothing to do with how bright a light bulb will be. Lumens, on the other hand, is a measurement of brightness. With a rating for Watts and for Lumens on a particular light bulb, you can determine how efficient your
Monocrystalline solar panels are panels cut from single slabs of silicon. They are identifiable by their consistent color throughout the panel and are often a dark blue to almost black color. Historically, monocrystalline panels have had the highest efficiency (around 15-17%) because being cut from a single slab of silicon allows a greater level of purity in the silicon, but have also been more expensive for the same reason. Polycrystalline panels are those created from many different pieces of silicon crystal....
In short the use of solar PV panels prevents the production of radioactive nuclear waste. Studies tell us that one megawatt-hour of electricity generated through a solar PV panel avoids more than five pounds of sulfur dioxide, 1,300 pounds of carbon dioxide, and about two pounds of nitrogen oxide emission. One of the greatest things about solar power is that it creates the greatest supply as demands spike. Especially on hot sunny days, when air-conditioning and electricity are high, and...
When using a grid-tied solar system, power from the solar kit is used as a supplement to the power grid that is feeding your house. During peak hours, when the most energy is being used, the load is usually more than the PV system can provide and the needed extra energy is taken from the power grid (and adds to your monthly power bill). However, during periods when electricity use is very low, such as everyone in the household being...
We understand taking an entire solar system with you when you move is a hassle. In actuality, there is no need to move your installed system and still be able to recover the cost of the system. Studies have proven that solar systems add value to your property and help it sell quicker. Homeowners understand the importance of renewable energy and know the future savings that solar systems can grant them. Usually, the increase in property value exceeds the initial...
In recent years research for improving solar technology has been an ongoing process. There has been a lot of research done to improve solar power technology. In Europe there is the European Kestcells Project that is funded with 3.7 million euros as researchers are looking to replace the present material in solar technology to another type of material that is more readily available, more cheaper, and that may be able to capture more energy from the sun. This project is...
