How to Buy Solar Panel Inverters

Posted by Mr. Hachis | On: Dec 03 2012

Invest money in buying and installing a solar energy system at home, and your investment will more than pay for itself given enough time. You'll save so much money on your utility bills that you will probably not need to wait more than five years to make your investment back. Most people who decide to take the plunge going solar, mostly only think of the most visible part of the system – those huge PV arrays on the roof that announce to everyone that you've gone green. Well, there's another part to any solar energy system that you need to think about too. Solar systems always need solar panel inverters to take the direct current put out by PV panels and convert them to usable utility-style alternating current.

No one much thinks of those solar panel inverters – they just seem like they are a cog in the wheel – that they don't do anything special. Of course, that's not true. You need efficient solar panel inverters to really get steady and usable power out of your solar arrays.

Certainly, you could just order solar installers to come in and do the whole thing, you wouldn't have to ever think about the components that went into the system. If you are more hands-on kind though, you'll find that you you can often get a better system to go shopping around yourself.

When you head to a dealer who deals in solar energy systems, you'll find a few different models on offer. How do you know which kind to buy? Well, you have to learn to ask a few pertinent questions here.

The first thing you want to know when you're confronted with an inverter at the store is, what kind of technology it uses. For the most part, pure sine wave inverters are the best. You see, direct-current is square waved. Alternating current, on the other hand, forms a smooth wave. The job of an inverter is to take the square-waved direct-current that comes in and turn it into a smooth-waved alternating current that your household appliances can use. This isn't easy.

When you have a bunch of sensitive electronics around the house – plasma televisions, computers and the like – you want a trusted to anything but pure sine wave current. Of course, you will have to pay a little more for this. If you find that you can't fit one of these in your budget, a modified sine wave model should do, too.

Solar panel inverters should always be bought to match the amount of electricity you'll be using around the house of the time. You see, your solar panels don't supply your home directly. That would be quite unreliable. Instead, they supply a battery. The battery stores all the direct-current and and that releases power as you need it in the house, through the inverter. So when you buy an inverter, you want to only look at the amount of power you'll need around the house at any given time.

Once you have that down, all you need do is to buy batteries to go with it, and you set.
