What is the typical performance advantage gained from using SunPower Performance panels?
We built the Performance solar panels for high reliability, high efficiency and low degradation—driving an estimated 8% more energy yield in a fixed space over the first 30 years of operation when compared to Conventional mono PERC Panels1.
How do Solar Panels Generate Electricity?
PV solar panels produce direct current (DC) electricity, where electrons flow in a single direction, like a battery powering a light bulb. In contrast, alternating current (AC) electricity alternates the electron flow, similar to a car engine's movement. AC electricity is generated by spinning a coil of wire near a magnet, powered by various energy sources like gas, hydro, nuclear, coal, wind, or solar.
How much energy do solar panels produce?
The amount of energy produced by solar panels depends on several factors, including the size and efficiency of the panels, the amount of sunlight they receive, and their orientation and location. On average, a 1-kilowatt (kW) solar panel system can generate approximately 1,600 to 2,500 kilowatt-hours (kWh) of electricity per year in a location with good sunlight.
What happens during power outages?
Your system will automatically shut down. Safety requirements prohibit the system from producing electricity during a power outage or blackout, because there is a chance that the system could feed electricity into the electric grid while utility workers are accessing the grid. The system will restart automatically when power is restored.
Are solar panels worth it?
Solar panels can be a worthwhile investment, especially in regions with abundant sunlight and favorable incentives. They offer numerous benefits, including cost savings on electricity bills, reduced environmental impact, and potential increases in property value. Solar panels typically pay for themselves over time through energy savings and potential government incentives, making them an attractive option for many homeowners and businesses interested in sustainable energy solutions and long-term financial benefits. The return on investment, however depends on factors like your energy consumption, location, available incentives, and long-term goals. That's why we recommend to conduct a thorough evaluation and consult with one of our solar professionals to determine the specific economic and environmental advantages for your situation.
How is the system managed in three-phase? How are imbalances managed?
The Enphase three-phase Q Cable allows balanced and automated power management of each phase. Alternatively, when using three single-phase cables, care must be taken to balance the phases by installing a similar number of panels on each phase.
The Envoy-S communications gateway can also provide phase imbalance monitoring to ensure authorised limits are not exceeded. The Envoy is able to manage PV power production at the microinverter level to maintain balance within set limits.
