When you are considering solar panels for sale there are several different factors that you will need to look for that are going to make your investment in these pay off in the long run. Some of the important thing to look for is the type of photovoltaic panels they are, the brand as well as the specifications. These three things are the most important.

When looking at solar panels for sale, there are three major kinds of photovoltaic panels to choose from. There are the portable style, the residential and commercial systems.

The portable solar panels for sale are generally very small and they usually supply a very low voltage and have limited power and often are hand held or portable types of gadgets. They can be rollable solar chargers, foldable panels and then small thin film type panels. The kind of panel you get will depend upon the application that you need to use it for.

The residential and commercial type of panels are generators that are made by using crystalline silicon, string ribbon or thin film technology. These are a lot bigger than the portable solar panels and they all require inverters in order to convert the direct current or DC to alternating current or AC.

Picking a good brand is another consideration for picking the kind of solar panels that you need. When you buy from a leading solar panel brand it will ensure that you get the service and the advice that will best serve your particular needs. Then when it comes to any repairs and maintenance, parts and labor, all of this will be better catered to when it’s a larger company compared to the small mom and pop shops.

Some leading brands to take into consideration would be: BP Solar, General Electric, Kaneka, Mitsubishi Electric, Sanyo, Suntech, Uni-Solar and Sharp. These are just a few of the reputable brands on the market today.

The professionals that work for these companies are well trained and they can help you size your solar power system, figure out your average power consumption and the number of hours from the sun at your location and they then can determine the specifications that you will need for all the related components.

Along with your solar panels there are other things that will be needed for the system such as batteries and mounts and these too the specialists can help you figure out the needs and how much will be needed.

You also should consider the warranty. Different companies will offer different types of warranty periods. So, it is important that when you are purchasing a solar system that you find out about the warranty to see if what they are offering is what you need.
