Q: How long do PV systems last?
A: A PV system that is well designed, installed and maintained can operate for more than 20 years. The basic PV module has no moving parts and can last more than 30 years. The best way to ensure and extend the life and effectiveness of your PV system is by having it properly installed and well maintained.
Q: Where are PV systems being used?
A: PV systems are generating clean power in a whole host of applications right across the world - from urban skyscrapers and military installations to remote villages in developing countries. PV electricity can be used to power all manner of household appliances, computing and communications equipment, water pumping and lighting. Cost-effective examples of lighting powered by PV include small garden lights, street lights, lighting for recreational areas, highway signs, warning signs and signals, and lighting for businesses and homes. Virtually any power need can be met with PV.
Q: I’ve heard that solar powered energy is the way of the future, but are there any facts to support this?
A: Worldwide carbon emissions are currently at some staggering 16 million tons every 24 hours, and global energy consumption is expected to increase at an alarming rate every year.
• The Sun has sufficient helium mass to provide the Earth with energy for another 5 billion years and, every 15 minutes, it emits more energy than humankind uses in an entire year.
• The Earth receives only one half of one billionth of the Sun’s radiant energy, but, in just a few days, it gets as much heat and light as could be produced by burning all the oil, coal and wood on the planet.
• The Sun represents 99.8% of the total mass of our solar system, its surface temperature is 6000ºC, and its total energy could melt an ice cube the size of planet Earth in just 30 minutes.
• The sun provides and has provided all the energy that we use.
• Worldwide, some 2 billion people are still without electricity and, for these populations, it is more economically viable to install solar panels than to extend established electricity grids.
• By using renewable energy systems, we are bypassing the millions of years that it takes to create the conventional fuel sources that are used today.
• It is reported that the earth's reserves of oil will run out within the next 50 to 70 years.
In more recent times, the environmental costs of burning fossil fuels have seen the world’s interest in solar energy systems gather even further momentum. With issues such as global warming and carbon emissions now scientifically proven and firmly on the political agenda, the demand for photovoltaic technologies is set to continue apace.
Q: When will renewable energy systems replace coal and nuclear power plants?
A: A major driver in the deployment of renewable energy is public demand for clean energy. Fossil-based energy pollutes the environment, and nuclear energy creates hazardous waste. If we stop to consider the environmental and health costs of fossil-fuel and nuclear energy, then renewable energy makes sense. So, in the coming decades, we will begin to see many more solar energy systems being built in areas that now use fossil fuels and nuclear energy for electricity generation. In developing countries, where there is little or no supply system for conventional energy, renewable energy is already being used because it is much less expensive than many other options, and the environmental benefits associated with this cleaner form of energy are significant.
Q: How much space would be needed for PV systems to meet the entire world's electricity needs?
A: Contrary to some popular notions, the landscape of a world relying on PV would be almost indistinguishable from the landscape we know today. There are three reasons for this. First, PV systems have siting advantages over other technologies. They can be put on roofs and can even be an integral part of a building, such as a skylight. Second, even ground-mounted PV collectors are efficient from the perspective of land use. Flat-plate PV technology is the most land-efficient means to produce renewable energy. Third, adequate sunlight is ubiquitous and often abundant, and present in predictable amounts almost everywhere
For example, in the United States, cities and residences cover about 140 million acres of land. The nation's energy requirements could be met simply by applying PV to 7% of this area - on roofs, on parking lots, along highway walls, on the sides of buildings, and in other dual-use scenarios. Not one single acre of new land would need to be appropriated to make PV the primary energy source.
