What factors affect how much I will spend on a solar energy system?

You will have choices to make and you want your money to go as far as possible, so it pays to know the areas that can significantly impact the price tag on your system. Without a doubt, the most expensive part of the system is the solar panels. Here you have a variety of choices. Please see the knowledge base article on the different types of solar panels to understand your options.

Your choice on inverters will also impact the price tag significantly. For instance, opting for microinverters over string inverters will be more expensive because of the sheer quantity of devices to install and wire as well as the more expensive price tag on the components. The knowledgebase article on inverters will also be instructive in helping you select the right technology for your application.

The solar panel mounting system is another area that will impact the price. Choosing to put the system on the ground vs. rooftop might increase the price tag on smaller systems because of the additional foundations and dirt work required. If you have options on where to place the array, then the value of the energy production will need to be weighed against the cost to determine the best scenario.
