The solar panels are the most important part of any home solar power system. They are at the heart of any solar power system and actually convert the sunlight to electricity. There are quite a few differences between solar panels, even though many panels look alike, and the homeowner must consider several things before choosing which panels to use for his or her home.

The construction and efiiciency of modern solar panels is much better than what was available in the past. Because of these advances, any homeowner will be better off with newer panels than they would have been even a few years ago. While it is true that all of the newer panels are much better than in the past, there are quite a few differences between different models of solar panels so choosing a panel should be done based on both your budget and how much electricity you want to produce.

The voltage requirement of the system you are building is the first thing to consider. You need to choose the voltage level among several standard voltages available for residential solar panels. Your choice of solar panels and power inverter will be dictated by this voltage level decision There are advantages to using higher voltage panels like less power loss in the long runs of wire, however higher voltage panels are also more expensive. Though there are some home solar panels with even higher voltages, most output at 12, 24 or 48 volts. Selecting panels with the highest voltage level your budget will allow will usually be the best option.

Number of volts in your solar system will also influence whichsolar charge controller you use.

Efficiency is yet another difference between different solar panels. Even panels that look the same can have almost 10% higher or lower efficiency than similar models. This is a big difference in the power that will be produced from a given amount of sunlight. The higher efficiency panels will produce a great deal more energy over the life of the panel. Because of the better efficiency, you will need to spend less because you will require fewer panels and you’ll also need less space as well. You should check the efficiency rating of any panels you are considering and generally go with the highest efficiency rating that you can afford. Getting a better quality panel now, even if you have to spend more money, will pay you back many times over during the lifespan of the panel.

Some of the newer specialty solar panels should also be considered. One type of newer panel combines both electric and thermal solar into a single panel. These can be used for both electricity and hot water. Using these panels, you can make the most efficient use of your roof space and double the benefit from the solar panels.

Solar panels that include a micro inverter are another newer development. A micro inverter is a power inverter that is built into the solar panel itself rather than being separate. Converting the DC electricity from the panels or batteries into the AC electricity that comes out of the sockets in your home is the job of the power inverter. The typical configuration is to the have all of the panels and batteries feed a single, larger power inverter than does the conversion for the whole system. A micro inverter in individual solar panels means that you can build your system incrementally instead of having to buy a big power inverter right away. With a micro inverter you can get the benefits of AC power at each step as you build up the system. One final benefit of micro inverters is the electricity coming from the panels will be at a higher voltage and will be AC which will reduce power loss in the longer runs of wire.

It’s great knowing that once you’ve decided to go with a renewable power source you are not only going to save yourself money, but also helping the planet. When thinking about renewable energy you should consider the main advantages of solar power.

The reason most people move to solar energy is the money savings you will see long term. You can go from running small appliances for free to saving thousands a year. All this depends on how far you take the solar power option.

If you take your home entirely off the power grid (no incoming electric power from the power company) you can expect to see massive savings as you will no longer be paying the electric company. If you choose to be inter-tied, for example to only heat your home water supply with solar power and use electricity for everything else, you can expect to see a huge savings but you will still have an electric bill to pay.

Some people choose not to make changes thinking it will be hard or cost a bundle. Wrong. Setting up a solar homemade power system can be done on a small budget for the cost of a typical one-month electrical bill – the average one is $200. Some parts can even be found free if you know where to look.

With the right set of instructions just about anyone can put together a solar powered generator for their own use. Then they could build a series of solar panels and tie them together to create enough energy to power their home or aspects of their house such as heating.

Building it yourself is another savings in itself. If you paid for someone to build your solar generator you would know how expensive labor is – that is why solar energy is considered expensive. People don’t think they can build them but they can. It’s easily done with the right information.

So, you used what you know to build a generator and you’ve saved money in the process. What are you going to use it for? Another advantage to solar power is that you can use it for your home or your business’ power needs.

Household power needs are extensive and vary greatly. You could choose to use solar power just for your heating and air conditioning system or your major appliances in your kitchen. On the other hand you could transform your entire house to solar power all at once or slowly, it’s up to you. Build a portable solar generator to have around for odd jobs outside to use in emergencies.

Seeing how a home can save money should really make you wonder how much a business could save. Another advantage of solar power for businesses is the cost savings for the company. Putting only a portion of the business on solar energy, say the heating and air conditioning system could ultimately save thousands of dollars per year. It just doesn’t make sense not to do it.

Armed with the knowledge of knowing why solar energy is advantageous goes a long way in helping you make the right decision about your energy needs. Knowing the main advantages to using solar energy makes it easy to decide to switch. And knowing you can do it yourself on the cheap is even better.
