The term “solar PV” is commonly used to refer to the technology used in residential and commercial rooftop solar installations. These types of solar installations are very different from one another, however. Understanding the key differences between residential and commercial solar PV will enable you to choose the right type of system for your home or business.
Residential Solar PV
Solar PV systems are one of the most common types of residential solar installations. They’re used to generate clean, renewable energy for homes and businesses. Most residential solar PV systems consist of a solar panel system mounted atop a roof or other outdoor space. The panel collects sunlight and converts it into electricity. Though residential solar panels provide many benefits, they’re particularly helpful during cloudy or rainy weather. In these situations, the amount of sunlight available for use may decline rapidly.
Residential solar PV systems can help homeowners avoid unnecessary energy expenses by maintaining a steady source of electricity even during these times. Some homeowners choose to install rooftop solar panels to reduce their monthly electricity expenses and offset the cost of operating their appliances. However, these savings should be weighed against the initial cost of the system. Homeowners that invest in solar PV may also have the option to lease their system over a period of 30 years. This can help homeowners avoid the upfront cost of purchasing a system outright.
Commercial Solar PV
Commercial solar PV systems are designed to generate electricity for businesses. These systems are usually located at an industrial or commercial property, such as an office building, hospital, or shopping center. Commercial solar PV systems are different from residential systems in several ways. The most significant distinction is that commercial systems are sized for long-term use. Residential solar PV systems are generally sized for a shorter period of time. Commercial solar PV systems can be connected to the electrical grid, which allows businesses to sell power back to the power grid.
This allows them to earn revenue while also reducing their overall carbon footprint. The operating costs of commercial solar PV systems are usually much lower than residential systems, which can help reduce the overall cost of a business’s electricity bill.
Differences Between Residential And Commercial Solar Panels
Power – Residential solar panels typically generate up to 5kW of power. This is enough to offset the power used by a typical home or small business. Commercial solar PV systems are generally sized for up to 10MW of power, which is enough to power hundreds of homes.
Cost – Residential solar panels are mostly cost-free. Commercial solar PV systems are generally priced per Kilowatt hour (kW/h). A residential system could cost as little as $0.10/kWh, while a commercial system may cost $3.00/kWh or more.
Installation – Residential solar systems are generally installed by a solar panel installer. Commercial solar PV systems are usually installed by a contractor.
Grid Interconnection – Residential solar systems are interconnected to the electrical grid. Commercial systems are usually not interconnected.
Maintenance – Residential solar panels require little to no maintenance. Commercial solar PV systems require periodic maintenance, such as cleaning and replacing the solar cells.
Solar PV systems are an effective way to generate clean, renewable electricity. They may be installed on rooftops or other outdoor spaces, or they could be housed within an indoor facility. Commercial solar PV systems are usually sized for long-term use and are interconnected to the electrical grid. Residential solar PV systems are mostly cost-free and provide a small amount of electricity. The key difference between residential and commercial solar PV systems is that commercial solar PV systems are sized for long-term use and can produce large amounts of electricity.
