Frequently Asked Questions
How does solar energy work?
Solar energy is captured by photovoltaic (PV) cells, which convert sunlight into direct current (DC) electricity. The DC electricity is then converted into alternating current (AC) electricity by an inverter. AC electricity is the type of electricity that is used in homes and businesses.
What are the main components of a solar energy system?
The main components of a solar energy system are PV panels, an inverter, a battery, mounting hardware, and wiring.
How much does it cost to install a solar system?
The cost of installing solar panels varies depending on the size of the system, the type of panels, and the location of the installation. ST Projects specializes in recommending a system that will work within your budget so contact us now for more information.
How much can I save on my electricity bill if I install solar?
The amount you can save on your electricity bill with solar depends on your energy consumption and the amount of solar energy you generate. Some customers go completely off grid, however, typically homeowners save up 70% on their electricity bills.
How long will it take me to pay off my solar?
The payback period for solar energy is typically around 5 years. However, the payback period can vary depending on the factors mentioned above.
What kind of maintenance do solar panels require?
Solar panels require very little maintenance. They should be cleaned at least twice a year to remove dirt and debris and the inverter and battery system should be checked for dust build-up. ST Projects provides a maintenance service. For more information go to our maintenance page.
How long do solar panels last?
Solar panels typically last for 25-35 years.
Do solar panels work on cloudy days?
Solar panels can still generate electricity on cloudy days, but they will not generate as much electricity as they do on sunny days.
