Solar panels that are used to harness the energy of the sun and convert it to electric energy can be purchased at wholesale volumes to qualify for bigger discounts. Before you make the decision of buying wholesale solar panels, you need to educate yourself on the basics of solar systems. Basically, there are two main types of solar electric systems, the stand alone and the grid connected. Let us explore the choice you have and the advantage and disadvantage of each system.
A stand alone system is an independent system that works completely unattached to the utility grid. Such systems are commonly used on remote home, cabins, house boats, RVs and telecommunications installations. For a stand alone system you can either use be AC or a DC system. AC systems are the used in appliances of modern life such as blenders, washing machines, microwave. DC is fine for telecommunications. Between the two, AC is the most cost effective. To convert DC power to AC we use an inverter. Inverter comes in two forms, the modified square wave and sine wave inverter.
Grid connected systems uses an AC system, and may or may not use batteries, and they need be equipped with a sine wave inverter. The advantage of using a grid connected systems is that it does not need generator back up due to the nature of the utility grid itself serves.
Before you move on with your decision of buying wholesale solar panels, decide on the kind of mount you want. Roof mounts are neat though they are hard to reach to adjust the angle. Side of pole mount is another alternative. They are designed to hold 1 to 4 modules and attached to poles with hose clamps or U-bolts.
Ground Mount is probably the easiest way to mount your solar panels. This mount actually resembles an A-frame. It is wise to attach this structure to a cement slab to secure it safely in place. Ground mounts can handle from 1 to 8 solar modules. Ground mounts can be used too to attach solar panels either to the ground, to a roof and or even to a vertical surface. Some ground mounts have adjustable legs while others are fixed. Take note that panels which are mounted on the roof of a residence are required by U.L. code to have ground fault protection, and that can easily add $200 - $240 to the overall cost of your system. Make sure that all panels should be grounded to minimize damage from lightning strikes. Vehicle mounted racks allow you to attach your panels where you need them and when you need them.
Before you make the final step in buying wholesale solar panels, take time to educate yourself. Browse the internet, ask for catalogs from the many renewable energy companies and read them. You will most often find that the equipment is fairly standard and the costs are similar. You can then familiarize yourself with the types and sizes of components available. Solar panels have a lifetime of 20 or more years and new ones have good manufacturers guarantee too. When you have done all the necessary research, then go ahead make your first wholesale solar panel purchase
