How to Find the Right Size for Your Solar Production

At the beginning you have to define the maximum budget for you solar module production line. After defining the budget you can define the maximum size you can get for the amount of money.

Therefor we will now make some examples for some production lines and some sizes with prices.

ATTENTION 1: The prices are only estimations and some figures for you to get an idea about the total costs. Of course there are a lot of variations so the prices can variate a lot...

ATTENTION 2: The prices are for the machines only! It does not include material financing, building and other costs

ATTENTION 3: We will make a complete overview about all the costs of the different sizes including building and financing of the materials in lesson no. 3!

What Size of the Production Line?

The smallest size that makes sense will be a 5 MW production.

5 MW means, that all the panels you can produce in one year will be a power of total 5 MW (5 million watt = 5.000.000 Watt).

It is a good idea if you want to start in the business and learn about the solar module production.

The biggest size we ever made was 600 MW which is quite a big installation for the beginning.

Below now we will talk about 3 possible sizes for your solar module production line:

Example 1: 5 MW Production Line

5 MW is a very small line with low invest and low risk. It is perfect if you are going to start and you just want to see if it is a good idea for you to start in the solar module production.

Advantages / disadvantages of a 5 MW line:
  • Good for: Making tests, producing special solar modules
  • Learn about solar: Learn how to produce panels, get into the process
  • Low risk: Low invest (about 120.000 Dollar) and therefor low risk to loose money
  • Low profit: With the small size and the small output 

Example 2: 30 MW Production Line

30 MW is a professional line with a reasonable size. This is not a line "only for learning". The invest will depend on the automatization of the line and the quality and will be in a range of about 500.000 Dollar and 2.000.000 Dollar.

Advantages / disadvantages of a 30 MW line:
  • Good for: Starting a real, professional production on a high level
  • Medium risk: Medium invest in machines (about 1.000.000 Dollar) and therefor medium risk
  • Medium profit: Big enough to make a good running profitable business

Example 3: 100 MW Production Line

With 100 MW you are at the top of the production lines and you will be able to compete even with the very big producers in the world market. The invest in the machines only will be more than 1.000.000 Dollar and can be 8.000.000 Dollars as well. The total amount for the machines will depend on the automatizations (workers or robots) and the quality (Made in China or Made in Germany).

Advantages / disadvantages of a 100 MW line:
  • Good for: Starting a real, professional production on a very high level where you can compete with the world market.
  • High profit: Big enough to produce for big projects and to compete with the world market
  • High risk: High invest in machines (about 3.000.000 Dollar)

Quality of the Solar Modules

With 100 MW you are at the top of the production lines and you will be able to compete even with the very big producers in the world market. The invest in the machines only will be more than 1.000.000 Dollar and can be 8.000.000 Dollars as well. The total amount for the machines will depend on the automatizations (workers or robots) and the quality (Made in China or Made in Germany).

Advantages / disadvantages of a 100 MW line:

With the size of the solar module production line also the quality is changing.

For example if you have a 5 MW line you have to make most of the work manual:

  • Manual soldering of the cells
  • Manual layup of the strings on the glass
  • Manual loading and unloading of laminator
  • And other manual stations

With a 100 MW line it will make sense to make automations in the most critical parts, for example:

  • Fully automated stringer for soldering
  • Automated layup of the strings onto the glass
  • Fully automated laminator with automated loading and unloading

Besides with a 100 MW line you will be able (and it will be profitable) to invest in testing equipment like:

  • EL testing machine
  • String tester
  • Optical cell tester (inside the stringer)
  • And a lot more!

This automatization and test equipment will give you a much higher reliability in the quality.

Together with other scale effects (you will be able to higher a quality manager with a bigger size of the line) the quality of a bigger line in AVERAGE will be better than with a very small line!

  • L’ Afrique a besoin de l’énergie renouvelable, pour son développement

    • Sunlight is abundant in Africa especially western part of Africa and there is huge market potential for solar panels and other accessories for solar energy. The problem is the huge capital required to start the production line by an African like me and would like to know if your company is willing to team up with an Africa who own land and ready to release for the setting up professional factory or Manufacturing line to produce, market and sell solar panels in Ghana and to the rest of Africa? If your organization is willing to look at this as business proposition in the future then I am be extremely interested

  • Good morning sir,I have a projects with Exxon Mobil oil and gass for sola energy in the area of borehole water for the workers qouters and the community.can you handle it?Attention Mr P.Thoma

    • Hi, thanks for your question. We are mainly a service and machinery provider for solar module production machines. We are not making projects for small solar installations. So if you plan to produce panels in your country then we are the right partner. If you search for partners to install solar water pumps, then you are not at the right partner here.

  • So far, it look more interesting, it look like good investment, but I still neeeld to put other things into consideration.

    • Take your time! Making solar panels is a big decision that have to be discussed accurately. Just contact us if you need an offer or you have other questions.

  • This is an eye opener. It would be nice to be at the top of the production lines with robots and all. Thanks.

    Thanks for the lesson

  • Thanks for the lesson it’s so helpful and insipiring , it is my hope to be an independent solar manufacturer

  • Thanks for the information, can the panel be produce by you and be exported to my location

    • Brother don’t always depend on importation of finished products. Have a manufacturing company’s dream, no sooner or later, it will manifest.

  • Hi, thanks for the overview. i am very much interested in solar panel production. More especially a panel that might be affordable to a local consumer.

    The communities which are to be serviced which do not have Electrical power or cannot afford it are the target population.

    I live in Uganda with a population of over 48 million people at least a good percentage of those will appreciate solar that will be a one time cost thus making this a good venture.

    I was reading thru your Financing and sales profile and you mentioned that you may be of some help in getting a business partners or a grant. My country relies on importation of these solar panels and I must say this is some good investment .

    I await your reply.


    • What we can do is, if you have an investor, that we can make the discussions together. But you have to find the investor, we will take care about the rest.

    • I live in phoenix and own lot of residential real estate I can sell the product or install on my own properties
