Polycrystalline Solar Panel: Way to Show That You Care For the Planet
By Matt | June 26, 2010
Polycrystalline solar panel is a boon for our planet that is already feeling the crunch of energy resources. Burgeoning population and its needs to sustain itself has had its toll on the earth and its precious ecology. Last century underwent intense industrialization to cash on the human needs. This in turn resulted in overexploitation and mindless utilization of planet’s once abundant resources.
Recently, increased global warming, irregular season changes and vanishing species have compelled humans to put a stitch in time. Depleting energy resources are unable to bear the ever-growing demand of increased energy consumptions. Albeit late, but humans have woken up to the reality that unconventional energy resources offer the best bait for future. These renewable resources like solar energy are turning out to be the most preferred alternate source of energy.
Solar energy: Abundant untapped resource
Polycrystalline solar panel is emerging as an easiest and the most economical solution to planet’s energy needs. Most of the parts of earth receive abundant supply of sunlight; however, this natural source of energy is untapped and underutilized. About an hour of solar energy absorbed by the earth is more than the total energy consumption of the earth for a year.
In spite such an abundance of natural energy resource, most of our power generation depends on fossil fuels and hydro-power. Both these resources are scarce and depleting speedily. Above all, these leave heavy carbon footprints in the form of pollution, wastes and damage to ecology.
Polycrystalline solar panel is a means to help us garner the benefits of solar energy. They are made from multiple silicon crystals. The panels are square in shape with smooth finish, thereby making them suitable for setup on rooftops. These panels are very durable and economical in comparison with mono-crystalline panels that are very expensive.

If positioned at correct angle to the fall of sunlight, one square meter of polycrystalline solar panel produces between 120 to 125 watts of power. This too is only 12 percent of the total solar energy that falls on the panels. More research is already on in this field to enhance the efficiency of the panels to gain maximum from sunlight falling on earth. Some encouraging experiments have shown to increase irradiance to about 170 watts and further, it depends on the size of the panel as well.
Are these suitable everywhere?
Polycrystalline solar panel works best at the ambient temperature of about 250C. Conversely to the popular belief, these panels lose their efficiency at higher temperatures. This performance is replicated by almost all types of the solar panels. So, those who need to monitor energy production in precise wattage must take temperature conditions into consideration.
Moreover, these panels are easy to install and many DIY kits and assistance is available in the market. Before installation, understand and calculate your energy requirements. Seek guidance from the experts and select a place that will avail the sunlight to the maximum. Rooftops are generally available and suitable for the purpose.
Polycrystalline solar panel is the beast option available to reduce our dependence on the traditional energy resources. This will also denote that we care for our planet.
