Photovoltaics - Repowering
Calculator for replacing old solar modules with new ones. Solar modules last a long time, but not forever. After some time, usually 2 to 4 decades, it may be worth replacing them with new modules. And since the technology is expected to improve noticeably during this time, you can expect more performance from the same area. The old mount can often be reused for the new modules, resulting in savings here.
This is a simple calculator to compare the performance of the old plant to the new one. It should be noted that the size of the old and new modules are often similar but not the same, so the number may vary. Please enter two of the three values for each plant.
Example: this roof plant consists of 32 modules of 185 Watt peak (Wp) each. If these were replaced by an equal number of modules with 385 Wp, the increase in power would be 108 percent.
