Complete guide on solar systems

Learn how solar panels works and choose the one that suits your needs best

425 Watt solar panels

425 Watt solar panels are great for commercial and utility-scale installations, though you can use them for your home as well. You can find 425W solar panels for sale in our store. Here’s some more information about them.

We sell the best monocrystalline 425W solar panels

There are mono- and polycrystalline 425W modules on the market. Choosing polycrystalline panels saves you money, but monocrystalline modules are more efficient and modern. Most solar manufacturers currently focus on mono- panels. This is why we offer first and foremost the most efficient monocrystalline panels, including 425 watt solar panels.

Solar PV systems can have different configurations

If you consider buying a 425W solar panel kit, first you need to decide what kind of system you want, because it will determine the essential parts of your installation .

Grid-tie with net metering

The most popular type of system is grid-tie: you are connected to the commercial grid with solar panels. You can send excess solar energy to your utility — it’s called Net Metering and helps you pay less for the electricity. A grid-tie system must have solar panels, an inverter and meter which is often provided by the utility.

Off-grid with batteries

You can be completely independent of commercial grid and utility as well. An off-grid system is the one where you rely solely on your PV installation. To be able to use anything in your home at night, you’ll need batteries to store the energy accumulated during the day. Here you need some panels, an inverter, since most household appliances need AC, a battery or two, and a charge controller to protect the battery.

Hybrid

Hybrid is a grid-tie and off-grid system in one. You are connected to the utility grid, and can draw energy from it whenever, but you also have a battery which ensures an interrupted power supply. Apart from panels, you’ll need an inverter, a battery and a controller. You’ll notice that not every inverter is suitable for this kind of system.

How many 425 Watt solar panels do I need?

The number of 425W panels you need to install depends on your energy needs. The simplest way to figure out the number of modules is to divide your daily consumption by peak sun hours in your area. What you’ll get is the combined power output of the solar array that you need. Keep in mind that the power output A 425W solar panel changes during a day and depends on your area, weather, inclination and possible shading. We suggest using Solar Calculator on our website for easy installation sizing.

Advantages of 425 Watt solar panels

  • Modern and powerful PV modules 
  • Latest technologies improve the durability of a module and performance at high temperatures.
  • Very-cost effective and price competitive.
  • Better energy production and high conversion rates means fewer panels are needed and installation costs are lower.

The average price of 425 Watt panels

425 watt solar panel price is slightly higher than the price of most residential panels. After all, a 425 W solar panel brings you more energy from a square foot. Currently, our online store has a great QCELLS panel in stock for $270.

What size of 425 Watt solar panel do I need?

Dimensions of 425 watt solar panels depend on the manufacturer, but generally they are 79” X 39” X 1.4” in size. Usually, 425 Watt solar panels have 144 half-cut solar cells which makes them similar to 72 cell panels.
