With the advent of technology, people have discovered ways to harvest electricity from the sun's light. The sun's light has energy and usually when it hits a surface, the energy turns into heat. For example when you turn your face to the sunlight, the warmth that you feel on your skin is actually the result of the energy in the sun's light turning into heat as the light touches your face. When the sunlight hits specific materials like silicon, the...
Contrary to common belief, solar power can work practically anywhere. Even if you live in a cloudy climate, there is usually enough sunlight to supply your electricity needs. Germany receives less sunlight hours than places like Seattle and Alaska, but still provides half of it's country/s energy from solar. The second factor considered is the amount of available roof space on your building. However, it is surprising how much electricity can be generated from a small amount of surface area...
In order to protect your solar panel from damage you must occasionally clean the panel and keep it free of debris. If you are living in a colder climate make sure that you keep heavy snow off of your solar panel as much as possible.
Photovoltaic cells refers to the solar cells which are responsible for converting light into electricity.
Each component in the kit will have a different reaction to the temperature but the two that react most notably are the solar panel and the battery bank. Solar panels perform better at lower temperatures due to the inner workings of the panel. Solar panels are created by using two different types of silicon, called n-type and p-type. N-type silicon has free electrons that want to flow, and P-type silicon has holes that want to accept those electrons. This creates a...
Under the energy crisis nowadays, solar energy become one of the most sustainable energy in the world. To convert the sunshine into real energy and electricity, we need to use some tools – That is solar panels. The photovoltaic panel is one of the most common used solar panel in the world. With the development of the technology, a photovoltaic (PV) solar panel usually have a life expectancy of 20-40 years. “20-40 years? Is it possible?” Some people would ask similar...
Our largest source of energy - The SUN is providing 970 trillion kWh worth of free energy on us every day. Enough solar energy strikes the United States each day to supply its needs for one and a half years.Put it another way, the amount of solar energy the Earth receives every minute is greater than the amount of energy from fossil fuels the world uses in a year!
A periodic inspection to remove dirt, debris and check electrical connections is all that is needed. Keeping the panel clear of snow and debris will allow for better results.
Yes, shade can be a problem because there are a number of individual solar cells within a solar panel that need to be expose fully to sunlight. This is mainly because of the way the wiring of the solar panels are designed. So for example if there were ten individual solar cells and due to shading, one of the cells did not receive sunlight exposure, this will affect the power output of the nine other individual cells, even if the...
Direction and angles are the one of the most important factors in setting up a system. These issues can affect the performance and the efficiency of the whole system. Ususally we suggest people to place the panels facing south, that is the general direction. But tons of factors can vary the exact directions and angles, including latitude and climate in your location. Consult a solar specialist would be a good choice for you if you need help.
