Very often, companies like to use their panel power as the pivotal selling point. While it accurately highlights the power of the panel, it doesn't highlight how effective it will be at generation. An large inefficient panel can have a higher rated power than a smaller but more effective model.
Photovoltaics is the most modular generation systems in the world, meaning the panel that goes into a solar farm is the same one that can go onto your roof. The only difference is that your roof space is limited and you need the highest efficiency panels if you want the best system you can buy.
At Winaico we believe in getting the most of your panel. For that reason we've built a useful tool to compare any model of solar panel to our models.
