The total cost of a solar panel installation includes more than just the panels themselves. It covers equipment like the solar panels, inverter, battery (if added), and all the fittings needed to install them. It also includes the cost of labor, scaffolding, insurance, travel, and other logistics to safely and properly complete the job. Some paperwork and approvals are required too, such as the G99/DNO application—but we include that at no extra cost, along with free bird protection to help keep your system safe and clean. The biggest parts that affect the overall price are the type of battery, inverter, and panels you choose.
