Monocrystalline or Polycrystalline Panels?

Both monocrystalline and polycrystalline solar panels perform the same basic function of capturing energy from the sun and converting it into electricity. Monocrystalline cells have always been the more efficient photovoltaic cell type when it comes to energy conversion. That is why they are typically costlier.

When planning an off-grid or backup power generator, both types of panels are good options to consider. Nevertheless, as far as effectiveness goes, monocrystalline panels are the best. The major difference between them is that monocrystalline panels have cells made from a single silicon crystal, while polycrystalline cells are made from multiple silicon fragments melted together.

As far as 100 watt solar panels go, it comes down to personal preference. The exciting thing is that these days, there are improved polycrystalline options with higher energy conversion efficiency. Simply put, if you need the best energy conversion ratio, choose a monocrystalline panel. On the other hand, if you need budget options, polycrystalline panels are cheaper.

Conclusion

A 100 watt solar panel is not sufficient to run an off-grid power generator for your home, but it still a great idea to have one around as a backup option. However, 100 watts solar panels are perfect for RVs and boats and a wide range of outdoor activities. We have selected and reviewed some of the best options available on the market today. They are relatively affordable, but most importantly, they are all portable enough to move around easily. We hope you found this review interesting and helpful.
