This gives SunPower panels the ability to produce electricity even on overcast days. SunPower panels are designed for efficiency with Maxeon® cell technology that features a smooth, light trapping surface to capture visible, infrared and ultraviolet light. Solar: Using the renewable resource of sunlight, solar power can be generated on both sunny and cloudy days. Wind turbines have the ability to generate power as long as wind currents cooperate. The rotating gearbox then powers a generator, which creates electricity. This rotation turns an internal shaft connected to a gearbox, which increases the speed of rotation by a factor of 100. Similar to an aerodynamic airplane wing or helicopter rotor blade, when wind flows across the blade, the air pressure on one side of the blade decreases, causing the rotor to spin. Wind: Wind power is generated when wind turns the propeller-like blades of a turbine around a rotor, which spins a generator and creates electricity. Most conventional systems rely on one central inverter, meaning the whole system can be affected by a single instance of shade. With microinverters under each panel, the panels operate independently-allowing greater efficiency in shade, because only the panels directly involved are affected. Solar systems need an inverter to transform electricity into power for your home, and SunPower® panels have a smarter inverter setup than conventional panels. Multiple solar cells sit on a solar panel, and with more panels comes more energy. Together these create an electric circuit that the electrons flow through to generate electricity. Solar cells are made of silicon and contain a positive layer and a negative layer. When these photons hit a solar cell, they knock electrons loose. The sun releases energy in the form of photons. Solar: Solar power is generated by capturing the sun’s energy and converting it to electricity. While both options are environmentally friendly and a smart way to lower energy costs, there are some key differences between solar and wind energy that homeowners should consider. The affordability and viability of alternative sources of energy is enticing many new homeowners to add a solar or wind system to their homes. Technology upgrades, storage improvements and equipment capabilities all contribute to more efficient power output and lower costs for systems. Incredibly efficient, greener batteries are making it possible to store the overbalance of solar and wind energy into homes. Solar panels are now sleek and design-conscious. Incredible strides in renewable energy technologies are making alternative power sources more obtainable than ever for American homeowners.
