Solar panels come in a range of sizes and weights, depending on the manufacturer. infinity PV Panels are exclusively sold as bulk orders, please contact us at [email protected] infinity PV. Investing in solar is the long term commitment. For the sizes, we can just look at the length and width because the height is usually just an inch or two and does not affect the module much. In most instances, increasing the size of your solar array is a sensible and fairly straightforward thing to do.
