There are a few keys in reducing the cost of these systems.
First you should consider DIY.This alone can save you thousands and give you the knowledge to upgrade and maintain a system on your own. There are many valuable resources online that can help you with a solar panel project. I have a few I highly recommend. More on that later.
You should also understand that solar panel cost is directly related to your usage. The more power you use the more panels you will need to produce the energy you need. This is a major, major factor. If you reduce your energy usage you reduce the size of the system you need. There are a number of simple ways to do this.
*Install compact fluorescent lights.
*Install a programmable thermostat.
*Weatherize your windows and doors.
*Install an on-demand or solar water heater ? 30% of your energy bill goes to heating water!
Lastly, you can save 30% just by installing a solar panel system. The government offers 30% tax credits if you put in an alternative energy source for your home. This credit is a dollar for dollar credit that is reduced from your taxes at the end of the year. Nothing better than FREE money!
Add all of these things together and solar energy is quickly becoming a viable option for the average homeowner. If you would like to stop paying an electric bill I suggest you look into it
