To ensure proper operation and maximum efficiency, it's important to make sure that the different panels are electrically compatible. This can be achieved through the use of appropriate inverters and electrical configurations. As per the predetermined rule of formulae, the same *voltage* should be connected in *parallel*, whereas the same *current* should be connected in *series*. Configuration of the mixed array is crucial as efficiency loss is possible.  2. **Similar Efficiency: **Ideally, the solar panels in the same array should have similar efficiency ratings. You can mix solar panels that have different wattages, but it is not usually advised because mixing different wattage panels reduced the efficiency and power output. If you mix highly effecienct panels with less efficient ones, the overall performance of the array may be limited by the lower-performing panels. 3. **Age and Degradation: **If you are adding new panels to an existing solar array, the older panels may have experienced *some degradation in performance over time*. Newer panels may have a different degradation rate, which could affect the overall performance of the array.  4. **Aesthetics: **Different solar panels may have different sizes, colors and appearances. Mixing panels with varying aesthetics may not be visually appealing, so consider the overall look of your solar array if aesthetics is important to you.  5. **Warranty and Maintenance: **Be aware that mixing different types or brands of panels may complicate warranty and maintenance issues. Manufactures typically have specific warranty terms and conditions, and these may vary between panels. - At SanTan Solar, we have a 1 year warranty on all of our used panels! 6. **Consult with a Professional: ** It's highly recommended to consult with a solar installation professional or engineer who can assess your specific situation. They can offer guidance on whether mixing difference solar panels is feasible and if there is an optimal choice for your particular circumstances.  ###### As seen in the examples below, there is a wattage loss for every configuration: ![Mixed panels in parallel](https://21594438.fs1.hubspotusercontent-na1.net/hub/21594438/hubfs/Mixed%20panels%20in%20parallel-1.jpg?width=1200&length=1200&name=Mixed%20panels%20in%20parallel-1.jpg) ![Mixed panels in parallel/series](https://21594438.fs1.hubspotusercontent-na1.net/hub/21594438/hubfs/Mixed%20panels%20in%20parallel_series.jpg?width=1200&length=1200&name=Mixed%20panels%20in%20parallel_series.jpg) ![Mixed panels in series](https://21594438.fs1.hubspotusercontent-na1.net/hub/21594438/hubfs/Mixed%20panels%20in%20series%20(1).jpg?width=1200&length=1200&name=Mixed%20panels%20in%20series%20(1).jpg) In summary, while it is possible to mix different solar panels in the same array, it should be done with careful consideration of configuration, compatibility, efficiency, aesthetics and long-term maintenance. Consulting with a professional is often the best way to ensure that your solar array operates effecitively and efficiently with mixed panels.  Shop our selection of affordable solar panels [here](https://www.santansolar.com/product-category/solar-panels/used-solar-panels/)!  --- Check out our most recent YouTube video below!    ### Leave a Comment ## Related Articles [![Used Solar Panels at the Gilbert, AZ SanTan Solar Showroom](https://blog.santansolar.com/hubfs/IMG_5108%20Large.jpeg)](https://blog.santansolar.com/blog-listing/used-solar-panel-deep-dive) [Blog Post](https://blog.santansolar.com/blog-listing/tag/blog-post) ### [Used Solar Panel Deep Dive](https://blog.santansolar.com/blog-listing/used-solar-panel-deep-dive) #### Used Panels and Their Benefits: If you know what to expect and know your way around used products, then used solar panels are a great, cost-effective way to go.
