Roof-mounted solar is probably the most common and affordable format for a solar installation. It produces power on a sun-baked, otherwise unused space - right next to where you need it. Not to mention solar panels help to cool your roof!
Covered parking is a very popular and beautiful way to incorporate solar for businesses. It provides a great place for EV charging, makes a big splash on the appeal of the property, provides a protected parking area for your employees and patrons, and produces power all day. Federal tax credits and depreciation are available on much of the structure as well, and adjusting for the cost of an engineered, attractive canopy without solar on it, ROIs can be seen very quickly!
Ground mounted solar or a solar field is typically mounted low but can be lifted high in the air as well. Mounted either on long rails or in a pod or flower shape, they attach to the earth using either concrete footers or poles dug into the ground. This kind of solar can come with special equipment to track the path of the sun, which can make up to 40% more power per panel than a fixed system. Some of these pods can have a ground footprint as low as one square foot and won't kill the grass underneath them. Ground mounted solar is also a great way to put a lot of solar panels in one place!
Solar storage with batteries can range from small, off-grid machines and home energy backups to large-scale diesel-extenders and community-wide grid management systems. They are typically and properly very complex and custom systems, but also battery, charging, and grid management technologies become more elegant, scalable, and affordable every day.
