305 Watt solar panels

305 Watt solar panels are a popular choice for home installations. With enough modules you can power every appliance in your house and sell the excess energy to your utility. On average an American house needs 17-25 modules to cover all of its energy needs. You can also install a panel on your boat or an RV – occasionally, even one 305W solar panel can be enough.

Advantages of 305 Watt panels

  • Great choice for residential systems
  • Good power output and affordable pricing
  • Fewer panels needed due to increased energy generation
  • Smaller number of panels means lower installation costs 

We recommend picking a model with the highest efficiency especially if space is limited. Read specifications for a panel that you like carefully. Some panels are better at dealing with shading than others and some are very sturdy and can survive any natural disaster. Pick a 305 W solar panel that will perform best in your circumstances. Think twice and check everything several times: don’t forget that a panel lasts more than 25 years and it’s hard and tiresome to detach it from the roof once it’s installed.

How much do 305 watt panels cost?

305W solar panel price primarily depends on the manufacturer. Chinese panels from brands like JA Solar, LONGi Solar and Trina are the cheapest and quite efficient. Modules from Japanese and European brands, like Panasonic, REC, QCELLS, are more expensive, but are very high quality. American panels from Canadian Solar and Mission Solar are the middle-of-the-road choice. In the last 10 years the prices have gone down by 80%, so it’s a great time to go solar.

Consider picking up additional equipment

While panels are the central part of a solar installation, there is some additional equipment that you’ll need. This list may include:

  • inverter
  • battery (for off-grid and hybrid systems)
  • charge controller (for off-grid and hybrid systems)
  • wires
  • combiner box
  • solar optimizers (to minimize the effect of shading on the inverter production)

All of it we have in our store as well as a variety of 305 watt solar panels for sale. Do not hesitate to leave us a message: our staff will reach out to you and help you to make a good choice.
