1. Size of the System The larger the solar panel system, the higher the initial cost. On average, most homeowners opt for systems that range from 5 kW to 10 kW, which is sufficient to cover most household needs. The cost is usually calculated on a per-watt basis, commonly falling between $2.50 and $3.50 per watt.

While the initial costs may seem daunting, it’s important to consider the long-term savings associated with solar energy. Homeowners typically see a reduction in their electricity bills, ranging from 50% to 90% depending on the size of their solar energy system and local utility rates. Furthermore, many states offer Solar Renewable Energy Certificates (SRECs), tax credits, and other incentives that can significantly alleviate upfront costs. The Federal Investment Tax Credit (ITC), for instance, allows homeowners to deduct a percentage of their solar installation costs from their federal taxes.
