    • CONS PROS  Free energy – The sun provides the “fuel” to   generate power for the home’s electrical system and components. This saves money on electricity bills. If the home is set up for net metering, any excess electricity generated by the solar power system can be transmitted to the grid and sold to the utility in the form of a credit. Clean energy production – Electricity generated by the sun produces no harmful emissions. This reduces the home’s carbon footprint. Installation incentives – Federal, state and local jurisdictions periodically offer grants, tax breaks, discounts and rebates for the installation of renewable energy products, including solar systems.  Reduced dependency – Generating your own solar power using panels on your roof means you are not as dependent on utilities and the electric power grid to provide your electricity.            Renewable Abundant Sustainable Environmentally Friendly Good Availability Reduces Electricity Costs Many Applications Shared Solar Silent Financial Support from Government/State Low Maintenance  Technology is Improving  Inconsistent fuel source – The sun doesn’t shine   brightly 24 hours a day. Some locations have trees or taller buildings that could shade your roof. Even during the long days of summer, the sun’s direct rays can occasionally be obscured by clouds. On such days the system is less efficient. Excessively high outdoor temperatures can also reduce efficiency of the system. High initial cost – Even with multiple incentives, a solar power system may still cost tens of thousands of dollars. Smaller systems can also be expensive to install. Cost depends on the home, its location, size and purpose of the system, the goals of the home owner, and the amount of work needed to prepare the house for the new system. Maintenance – Generating your own electricity means that the upkeep of the system is in your hands. PV panels need to be cleaned periodically so that dirt and debris do not reduce efficiency. In the case of a severe storm, it will be up to you to arrange for a qualified professional to repair any damage.       Expensive Intermittent Energy Storage is Expensive Associated with Pollution Exotic Materials Requires Space
