When it comes to powering your home or business with solar energy, it's important to understand the differences between the various types of solar panels available. Monocrystalline panels are often touted as the most efficient option and are therefore better when installed for larger energy systems. However, polycrystalline panels are also a good choice for both small and large scale installations. When evaluating the solar panels themselves, be sure to review the efficiency, power rating, warranty, and cost-effectiveness of the different manufacturers. REC's entry-level Twinpeak panel range offers excellent value for money and gives you access to the company's 25-year product and performance warranty.
Q-Cells includes a 12-year product warranty to cover any malfunctions your panels experience during the manufacturing process. REC produces some of the best budget solar panels, and its Alpha Black series is popular with homeowners who have a keen eye for aesthetics. In addition to its efficiency, it's important to understand the differences in solar panel manufacturing so you can choose the most efficient solar panels for your commercial or residential installation. Most companies offer a material warranty of at least 10 years, but the best solar panel manufacturers will guarantee against equipment failure for 15 or even 25 years. All manufacturers produce a range of panels with different efficiency ratings depending on the type of silicon used and whether they incorporate PERC, multi-bus bar or other cell technologies. Your roof is not a very cozy place, so conventional solar cells lose energy over time due to corrosion and breakage.
There are several well-known brands based in North America that focus on supplying the growing North American market. When choosing a solar energy company to power your home, look for one that has a high efficiency rating to maximize the amount of energy your solar system generates and a good guarantee that protects you from future maintenance costs. If your roof requires multiple planes for the panels or has some shade from the trees, consider paying a little extra for microinverters. Solar energy for condominium unit owners is gaining popularity across the country, as more and more states are drafting laws to promote accessibility to clean energy. As explained in detail below, the efficiency of the panel is determined by two main factors; the efficiency of the photovoltaic (PV) cell, based on the design of the cell and the type of silicon, and the total efficiency of the panel, based on the cell design, configuration and size of the panel.
