Recent price changes in solar panels:

Following a challenging 2022, the Ukraine-Russia war and its associated energy crises have increased the cost of solar equipment and installation labor. This is great news for the cost of solar equipment and installation labor.

Price declines for solar panels are common. According to Berkeley Lab's Tracking the Sun report for 2022, the installed cost of home solar panel systems has reduced 39 percent over the last 10 years, from $6.20 per watt in 2012 to $3.80 per watt in 2021. The fundamental driver of this trend has been the decrease in the cost of solar panel modules. Since 1998, the cost of solar panel modules has dropped by 92%.

The installed price of home solar panel systems has dropped 39 percent over the last decade, from $6.20 per watt in 2012 to $3.80 per watt in 2021, according to the 2022 edition of Berkeley Lab's Tracking the Sun study. Over time, falling solar panel module prices have fueled this tendency. The cost of solar panel modules has dropped by 92% since 1998.

Prices for solar panel modules have dropped by 47%, from $1.03/watt in 2012 to $0.55/watt in 2021. Following that, prices continue to fall.

Factors influencing the cost of solar panels include:

1.Exchange rate:

The price of solar modules is influenced by two major factors: material imports and oil imports. First, by importing solar module ingredients, the exchange rate influences the production cost of solar modules.

Polysilicon is the basic ingredient used in solar modules. Polysilicon is formed as ingots before being sliced into wafers. These wafers are incorporated into the solar cell, which is primary energy conversion unit. Finally, the solar cells are put together to form solar modules.This is why silicon is essential in the production of PV panels.

The Nemet Institution (2005) employed a model that included polysilicon as an independent variable and solar module pricing as a dependent variable. According to the findings, silicon expenses account for around 12% of the "learning-by-doing" effect. Similarly, the Pillai Institution (2014) found that for every 1% fall in silicon prices, solar module prices fell by 0.9%. Thus, solar module prices are affected by both material prices and the strength of the currencies of the nations that influence the cost of material imports.

2. Oil prices:

We must recognize that renewable energy is being developed as a replacement for oil.

Since 2002, global oil prices have skyrocketed. As oil prices rise, so does the quest for alternative energy sources. As a result, the "primary effect" or "substitution effect," or the effect of oil prices, cannot be ignored in evaluations of renewable energy pricing. Oil has an indirect impact on PV costs as well. Oil, for example, is seen as a production input alongside labor and capital.

Increased energy prices may promote technological progress. Typically, more R&D lowers the cost of renewable technologies. As a result of rising oil costs, R&D spending rises, lowering the cost of solar panels.

Cheon and Urpelainen (2012) give an empirical analysis of the impact of oil prices on the growth of renewable energy technology. According to the data, greater oil prices are connected with increased governmental spending on renewable energy R&D and patents.Wong, Chia, and Chang (2013) found similar results when they investigated the elasticity of energy R&D in respect to swings in oil prices. The findings show a beneficial relationship between oil prices and renewable energy R&D. As a result, rising oil prices may speed technological progress and result in lower solar panel costs.

3. Cost:

(1) Installation charges
According to Berkeley Lab's Tracking the Sun study (2022), the installation cost of solar panel systems has decreased by 39% over the last decade. The typical installed price of a residential solar panel system in the United States in 2012 was $6.2/watt. The median in 2021 is $3.8/watt. Residential solar panel system installation costs have dropped 39% in the last decade, from $6.2/watt in 2012 to $3.8/watt in 2021.

(2) Intangible Costs
Labor and other running expenses.
The balance of system and soft expenses accounts for approximately 80% of overall system cost. The cost of a solar panel module is approximately 15%, and the cost of an inverter is 5%.

Will the cost of installing solar panels continue to fall?

To present, the decrease in the installation cost of solar panels has been caused by a large decrease in the price of solar panel modules over time.

While solar panel module prices may continue to fall in accordance with Swanson's Law, they have dropped to around $0.50/watt and account for only 15% of the total cost of solar panels installed.

Moving ahead, any more major cost savings will have to come from one of the other price components.

However, inverter prices, balance of system costs, and soft expenses have not fallen considerably over time in comparison to development history. As a result, it is expected that the cost of installing solar panels will soon begin to level off. The market for solar panels is rapidly developing, and clients have numerous options. When purchasing solar panel panels, it is critical to select a recognized, reasonably priced business.
