Strategies to Reduce the Costs of Solar Panel Production

Investing in a solar module production business can cost anywhere from $100,000 to a few million dollars depending on the size of the project. That said, reducing the costs of solar panel production can have a huge impact on improving the return on investment.

In this article, we look at several cost-saving strategies for solar module production.

Analyze Production Processes

One of the first things to consider when looking for ways to reduce the costs of solar panel manufacturing is production processes. Analyzing production processes can decrease costs by identifying inefficiencies and opportunities for improvement.

Analyze the system thoroughly to identify where time and resources are being wasted. Then make changes to eliminate inefficiencies, which will lead to eventual cost reductions. This could be in areas such as materials, labor, and energy.

Lean Manufacturing

Lean manufacturing is a method of production that seeks to eliminate waste, maximize efficiency, and reduce costs. The idea behind lean manufacturing is to eliminate any activity that does not add value to the product.

For example, by using advanced production techniques, manufacturers can reduce the amount of time and materials needed to produce solar panels. In addition, by using cheaper energy sources like solar, manufacturers can decrease the cost of energy used in production.


Manufacturers can use automation to improve solar panel production. This reduces labor costs by eliminating the need for manual labor in certain tasks. 

For example, robots can be used to perform repetitive non-critical tasks like assembling solar panels, reducing the need for human workers. Eliminating manual work will increase productivity, allowing manufacturers to produce more solar panels in less time and with fewer workers.

Furthermore, automation can reduce production errors in PV manufacturing by increasing accuracy and precision in the production process. Automation leverages sensors, vision systems, and other technologies to detect and correct errors.

By replacing manual labor with robots, automation reduces human error, which is a leading cause of production errors. By eliminating human error, manufacturers can decrease the number of defective products and increase yields, resulting in cost savings.

Negotiate with Suppliers

Negotiating with suppliers can be an effective way to reduce costs in solar panel production. Negotiating supplier terms can help a business secure better deals. This negotiation includes price, delivery time, and payment terms. Decreasing costs is the ultimate goal.

Negotiating with suppliers also helps a business reduce the risk associated with suppliers, such as ensuring that suppliers follow safety regulations and quality standards.

Additionally, negotiating with suppliers allows a business to consolidate its supply chain, which lowers the costs of solar panel production by streamlining the procurement process or reducing the number of suppliers.

Finally, negotiating with suppliers can help a business obtain buyer’s credit, which can reduce the financing costs for solar panels. Also, low-cost suppliers may offer longer payment terms or discounts for bulk orders.

Apply for Financial Incentives

Many countries like Germany, Spain, the USA, and others offer financial incentives that offset the cost of operations for renewable energy manufacturers. There are many such incentives and they can take the shape of subsidies or cheap loans.

Researching and taking advantage of these incentives can have a massive impact on reducing the cost of solar panel production.

Minimize Inventory

Minimizing inventory significantly impacts cutting costs, since it reduces the need for storage space, the risk of possible inventory obsolescence, and the amount of inventory that must be managed.

Taking a lean approach to inventory decreases costs associated with inventory damage, insurance costs, and theft.

Outsource Non-Critical Functions

Outsourcing non-core production processes lowers costs by taking advantage of economies of scale, reducing labor costs, and reducing the need to invest in expensive equipment.

Additionally, outsourcing lowers costs associated with delays, because it ensures that products and services are delivered on time. Additionally, there is less need to carry more inventory if part of the production is outsourced.

This leads to cost reductions by decreasing the need to spend money on insurance, storage space, and other costs associated with maintaining inventory.


Automation, lean manufacturing, outsourcing, minimizing inventory, financial incentives, streamlining production, and negotiating with suppliers: these are some of the best ways to cut the costs of solar panel production and improve the profitability of a solar manufacturing business.

Not all of them will be applicable in all situations. It’s important to try each of them individually to see what type of results they produce based on the context of your project.
