Increasing the output of your solar power system is best done by adding more solar power panels. Each panel has its own rated output, which is the amount of electricity it produces under peak conditions. The higher the panel rating, the more electricity put out. Of course, like most any other product, you get what you pay for.
If we're talking in terms of how to improve the ratio of solar power output to power consumed in the home, then there is an even better and cheaper way to help your solar power system make a bigger difference: energy efficiency. Most solar homeowners take steps to improve energy efficiency before installing a solar system. And they are right to do so. But there will most definitely be times after your system is installed to upgrade to more energy efficient appliances, lighting or insulation, among others. For more information on energy efficiency, read this blog post: 10 Ways To Prep Your Home For Solar.
Solar power systems require very little maintenance - typically the occasional cleaning is all that is necessary - but following that simple regimen to a tee will ensure maximum output (if not increase it). Also, at present, inverters need to be replaced every 10 to 15 years. That's a long time span, but making sure you do it will increase system output, especially if you figure that inverters 10 years from now should be even more efficient than they already are (85-90%) which, of course, will increase output.

C.E. Solar / Connector Electric did a first class job for us! We shopped around, they had the best price and really know their business. George designed a system that is far superior to the other companies for a lot less money. I would recommend them to everyone.
SolarCraft installed a solar heating system for my pool. The pool is warm and more enjoyable.
