SOLAR ENERGY SYSTEMS
Solar energy systems converts the light from the sun into energy that we can use in our everyday lives. The most common conversion technology used in new residential and commercial projects is solar photovoltaic (solar panels). If you are thinking of using solar energy, there are three areas you should consider.
Solar panels convert sunlight into electricity. The panels used in residential applications typically do not track the sun throughout the day, while commercial applications use sun tracking systems with more frequency.
All solar electricity systems are either “on-grid” or “off-grid”. On-grid systems do not store any energy. Instead, the electricity either gets used right away or is sent to your city’s electrical grid (where you get paid for the electricity you send to the grid). Off-grid systems usually require some form of energy storage.
Solar energy systems are getting more economical every year. The total cost and payback period of your system will vary depending on where you live. For most of the world, solar energy systems have not reached the point where it is cheaper than buying power from your local utility company. However, the costs are now low enough for the early adopters to have a reasonable payback period. If you are thinking about solar power for your home, you should definitely see what incentive programs are available.
