What is the difference between on-grid and off-grid?
On-Grid Systems tie directly to your utility grid, offering an alternative source of energy in addition to what your utility company provides. By utilizing on-grid solar systems, you can greatly or completely reduce your electricity bill. In addition, depending on the size of your on-grid system, you may receive monetary returns. Off-grid systems do not tie to the utility grid and are sustained using a battery bank. The battery bank can be hooked up to an inverter, which converts DC voltage to AC voltage allowing you to use any AC appliances or electronics. Common off-grid applications include cabins, Off-Grid vehicles, boats, and dry camping. Off-grid systems can also be used in a variety of other applications, including emergency power backup during a power outage.
What is the difference between monocrystalline and polycrystalline?
There is a difference in the manufacturing technique, and as a result monocrystalline cells are more efficient. The monocrystalline cells can produce more power in a smaller space. Also, monocrystalline panels have a darker blue color, almost appearing black, and are usually higher in price due to the increased efficiency. Polycrystalline panels on the other hand are less efficient and require more space. However, the difference is size and efficiency do not impact power. A 100 Watt monocrystalline panel and a 100 Watt polycrystalline panel will both output 100 Watts, neglecting power loss in the system, but a monocrystalline panel will output 100 watts with a smaller surface area.
How long will PV modules last?
ACOPower Framed Solar Panels have a performance warranty of 25 years. After 5 years they should output more than 95% of the rated power, after 10 years it is 90% and 25 years it is 80%.
How does solar system fair in extreme weather conditions?
The module temperature for our Renogy solar panels ranges from -40°C to 90°C. Whereas our charge controllers have an operating temperature of -35°C to 55°C. The majority of our solar panel are water proof and do fare well in extreme conditions however, our charge controllers are not water proof. We recommend storing and securing the charge controller in a well ventilated dry space.
