Among those factors include the type of material, its accessibility, complexity in manufacturing and amount available and needed. Crystalline silicon is the most common semiconductor material used to make photovoltaic cells otherwise known as PV or solar cells.
Photovoltaic, or PV for short, is a technology that converts light directly into electricity.
Since monocrystalline technology offers customers a better product along with greater bang for their buck, The Solar Company makes certain that this is the material used for their customers. This particular post will focus on silicon, our most common and prime solar material friend. Since the very beginning of solar panel production and installation, the demand and supply for solar panels have shifted throughout time. Previously, silicon supply was more limited; thus, contributing to the high cost of production and pricing.
If enough solar energy can be used to power the residential property or commercial property and outweigh the cost of conventional electricity, then the solution and decision making for customers becomes simple. Today, many local government jurisdictions have also provided subsidies and incentives in order to drive a greener environment. At this rate, it is likely that demand will continue to grow alongside the growth of supply, keeping prices lower than before thereby adding value to the Earth and to the living things that reside on it. As this graph shows, the best return is achieved when you buy solar panels now, rather than wait for further price drops. Rising inventory levels of photovoltaic (PV) panels and new production capacity coming online is driving solar PV prices lower and thereby, bringing solar energy closer to grid price parity. To get a better perspective on the solar PV industry, let’s examine inventory levels for some of the leading solar PV suppliers.
While it is important to control inventory levels in relationship to sales, revenue growth is predicated upon price, performance, and return on investment for prospective customers.

There appears to be a lot riding on the success of thin-film PV and as prices fall for crystalline PV, the closer we get to grid parity. The bottom line is that despite the lower PV panel costs; we are still not at parity with hydrocarbon fuels such as coal and oil.

A recent report by Ernst & Young shows yet again how dramatically solar PV module prices are dropping. However, it’s important to remember that these are simply module prices — the actual cost of solar electricity is determined by the cost of other equipment, construction and installation, and permitting. In my opinion, there will be two achievements (both occurring over an extended period of time across various locations) that will make solar mainstream. For retail generation, the difference will be made when consumers can see significant cost savings from a PV installation that are assured.
The bottom line is that the solar industry is thriving even in our complicated, semi-parity world. These cells are built into modules that are brought together to create what we call solar panels. PV is a developing field and utilizes several different technologies: monocrystalline (single crystal), polycrystalline (multiple crystal), cadmium telluride, gallium arsenide, or amorphous silicon deposited as a thin film. If demand increases and supply remains unchanged, then it leads to higher equilibrium price and quantity. If demand decreases and supply remains unchanged, then it leads to lower equilibrium price and quantity.
If supply increases and demand remains unchanged, then it leads to lower equilibrium price and higher quantity. If supply decreases and demand remains unchanged, then it leads to higher price and lower quantity.
Slow or stagnant demand alongside limited supply was the economic beginning of solar panels — an economic status that has continually changed even till today.


In the last 10 years or so; however, with operations to produce more silicon supply, prices have been dropping for solar panels making it more affordable for customers as well as more beneficial toward their investment goals. This is driven by the missed income from solar panels if you decide to wait for later, since you miss the opportunity of earning 800 pounds every year. The report, which focuses on the UK solar market, illustrates the continued downward price pressure on panels due to a steady ramp-up in global manufacturing capacity. For wholesale generation, it will be the point at which large volumes of solar become attractive to utilities even accounting for dispatchability.
In essence, the droves of new solar customers will be driven by cost savings, not cost parity. Over time, prices will continue to fall and incentives will become increasingly unnecessary. The major advantage of monocrystalline cells is their higher efficiency and therefore smaller space requirements. The clean-tech advisory firm Clean Edge has developed a 10 year price forecast in US dollars, and based on this we can forecast prices in the UK as well.
And when you take into account future drops of the Feed-in-Tariff (3.5% in July) and the potential for import tariffs on Chinese panels, it becomes even more clear that buying solar panels now does provide a much better return rather than waiting for future price drops. By 2013, the average selling price of a solar module will be down around $1 a watt, from $1.50 today.
This could achieved either through the competitiveness of solar plus energy storage, or by making solar so cheap that supplementing solar generation with natural gas or another peaking resource beats the peaking resource alone. Thin film can be cheaper to manufacture but is significantly less efficient, requiring more area which results in more labor, mounting hardware, and bottom-line costs.
