Solar Photovoltaics (PV)
Introduction to Solar PV
Solar photovoltaic (PV) systems convert sunlight into electricity. They provide a renewable energy source of electricity for buildings, help reduce electricity bills, and lower greenhouse gas emissions, making them a sustainable choice for building owners and their residents.
How Solar PV Systems Work
These systems consist of solar panels, a rack to hold panels at ideal angle, an inverter to change DC to AC power. When solar PV system is installed the utility will have to install a special electric meter to record all electricity consumed by building and give a credit for all electricity exported to the grid for others to use. Solar panel efficiency is around 15%-22% depending on the type of materials used in manufacturing the panels. Solar PV panels can be mounted directly on roofs, south-facing walls and ground-mounted racks which can be used to cover parking areas.
Many building or homeowners pair their solar installation with a battery storage system to ensure the solar array will continue working during power failures.
Average Lifespan: 25-30 years
Typical Payback Period: 6-10 Years
