Simpleray uses top-of-the-line equipment in our installs. Solar system designs that use high-quality equipment tend to produce more electricity than those using low-quality materials. More production means less energy you'll need to draw from the grid or more credits (if you're using Net Metering), all of which means more savings for you. Inferior equipment may be cheaper upfront, but it is likely to impact your overall savings.
We are currently working on a comprehensive guide that will detail our choice in the equipment that could make up your array. Please check back periodically!
