Benefits of Photovoltaic Cells

The term photovoltaic refers to the direct transfer of sunlight into usable energy. Photovoltaic cells are found within the solar panels of residential homes, solar garden lights and commercial buildings to allow the sunlight to be turned directly into the electricity we need to run our homes and businesses. Comparable to fossil fuels, solar energy is available nearly everywhere on earth where the sun is prominent. The science and technology behind photovoltaic cells allows us the opportunity to utilize a never ending supply of energy that has absolutely no risk of rising in price because it is free.

Photovoltaic cells and modules come in several different sizes. The most common is often 10cm by 10cm and this size has the capacity to generate about half a volt of electricity. Of course photovoltaic cells are combined or bundled together in solar panels in order to produce larger amounts of electricity at a time for best results. This is the only way solar energy would e possible for the masses; residentially as well as commercially. To give you an example, if you have a 12volt module or solar panel there are more than likely at least 30-40 photovoltaic cells within this panel to transform the sun into electricity upon impact.

Benefits of Photovoltaic Cells

• Produces completely free electricity
• The sun is never going to be depleted within our lifetime
• They covert 15% of the sun’s light into electricity
• Almost zero maintenance is involved
• No moving parts, liquids or chemicals needed to make this happen
• Available everywhere on earth

There are many benefits associated with the technology of solar power brought to us by photovoltaic cells but there are also several disadvantages that should be noted here as well. If you have not yet looked into solar panels for your personal home or cottage you will soon find out that the cost of solar panels is quite expensive and for many people is not quite an option financially. It won’t be long before the initial cost of solar panels will become more affordable to the masses but for now it is a major expense. Remember, after the initial cost of solar panels and proper installation you will be living on free electricity for the rest of your life; this is an energy and money saving goal we can all get on board with.

Sizing your Photovoltaic cells and panels can be a difficult task. You want to ensure that you get enough cells to power your home or cottage on rainy and cloudy days as well as sunny days. What this means is enough cells to store the energy to be used on days when the sun is not directly powering the home. This is an aspect that is often over looked because we assume the sun is out everyday which it is, but it is not always a bright and sunny day. The estimate just how many cells you will need to power your home a simple calculation can be done. Start with one electrical device at a time and multiple its power in watts by the number of hours a day it will be on. Go through each and every device and your home and you will find the number of watts you need each and every day to power your home as it is now.

Based on solar energy and photovoltaic cells you can save a great deal of money in the long run and help save the planet at the same time. It is time we allow the natural resources of our planet to guide our lifestyles and solar energy is the first major breakthrough we can all utilize in some form or another.
