In this section of our website there are all 450 Watt solar panels for sale that are currently available in our store. It’s a great choice for commercial systems, though you can use them for your home as well.
The key difference between home and business systems is their scope: commercial installations are much larger in size. For this reason people choose different panels for these projects. Home systems generally consist of solar panels that are in the 330-380 Watt range. Business installations generally feature PV modules that are over 400 Watt in power output, such as 450 W solar panels.
Powerful panels are larger in size than typical modules for residential systems. For instance, a 350 W solar panel has 60/120 cells and is close to 66 × 39 inches in size. A 450 watt solar panel often has 72/144 cells and it’s closer to 77 × 39 inches in size. The exact dimensions of a solar panel depend on a model.
Since commercial systems are large, the panels are often installed on the ground because there is not enough space on the roof of a building. Ground-based installations are cheaper but they take up land and they require more maintenance. Business systems take a long time to build. The permitting and building process may take up to a year whereas the most simple home systems are built in 3-6 weeks.
Solar energy today is considered to be the cheapest among the most prominent types. The cost of PV modules has dropped by 80% from 2010 to 2020. However, the 450 watt solar panel price highly depends on the manufacturer. Chinese panels are the least expensive. American brands offer a more pricey product with better warranties. The most expensive solar panels come from companies like REC, Panasonic, Sunpower. Their PV modules have the best warranties and they are high-quality, efficient and modern. Overall, you can expect the 450w solar panel price to be higher than an average home panel since this one has a lot more power in it.
What is a single 450W solar panel capable of? How much energy will your solar panel generate depends on where you live, positioning and angle of your panels, weather and shading. For instance, a single home 450 watt solar panel in California will produce roughly 2.5 kWh per day. It’s enough to run a stove for 1-3 hours or to keep a TV on for 24 hours. An American house needs around 30 kWh per day on average and around 900 kWh per month. A 5-6 kW solar system covers these needs. You’ll need twelve 450 Watt solar panels to build one.
