Previously 3 decades, the photovoltaic industry maintained a rise rate of 20 % around the average, whilst in the last 5 years, by having an average annual rate of growth of up to 35 %. By 2007, the worldwide PV power installed capacity is 9.a million kilowatts, the development rate increase to 33 percent. in 2007, capacity of two.two million kilowatts is installed, and also the rate of growth is 40%.
Around the positive view, within the next 3 decades ,the pv industry will keep a rise rate in excess of 25 %, as the pessimistic view is this fact judgement isn’t according to reality.
Positive faction believes that because the technological progress and industrial expansion, photovoltaic power generation costs is going to be rapidly reduced, therefore it bring a simple interest in the development, the procedure will run car century. The second area of the rate of growth will decline, for the reason that the bottom PV is going to be huge.
The pessimistic view is dependant on the greatest obstacles for photovoltaic industry – the cost. Within the Western civilized world, they mainly undergo several types of financial subsidies to aid the introduction of the, for example U . s . States allow advance photovoltaic project using the financial and tax incentives, and offer the Internet cost of photovoltaic for 21.29 cents / unit.
Based on our judgement, in line with the price of photovoltaic, the following 3 to 5 years, in some time to some areas, photovoltaic may have cost advantage. U.S. Ecological Co-op non-profit organization states, the price of solar energy is going to be equal using the traditional fossil energy for power generation costs. Using the decline from the cost for solar energy, while coal, gas and also the rising price of nuclear power, U . s . States can come towards the intersection by 2015.From Comprehensive judgement, the photovoltaic industry have a high growth period.
