Though monocrystalline panels are generally more expensive, some households will find that their overall system price will be cheaper than if they used polycrystalline panels. Because more polycrystalline panels are required to generate the same amount of energy, homeowners will need to invest in more installation costs, racking equipment, and potentially in inverters (if you’re using string inverters*). Monocrystalline panels also perform better in higher temperatures and shady conditions, though there will only be marginal efficiency differences. Paying a higher upfront price for monocrystalline panels might also make the most economic sense in the long run if you buy your system as opposed to leasing it. With a higher efficiency and more energy generated, you might see a greater return on your investment in the form of lower energy bills.
