There’s no denying the importance of solar energy. The return on investment of going solar is highly valuable, and not just financially, but for the sake of public health and environmental sustainability. With every passing year, solar energy becomes more popular for home and business owners as people learn its many benefits, and as installation costs decrease.
Benefits of Solar Energy:
Solar panels convert solar energy or sunlight into direct current (DC) power by the photovoltaic (PV) effect.
All Solar PV power systems work on this same basic principle.
The DC power thus generated may be stored in a battery or needs to be converted by a solar inverter into an alternating current (AC) power source, which is then used to run various appliances or may be fed into the electricity grid for credits.
The three main types of Solar PV power systems are :
Off-grid systems work independently of the grid but have batteries which can store the solar power generated by the system. The system usually consists of solar panels, battery, charge controller, grid box, inverter, mounting structure and balance of systems. The panels store enough sunlight during the day and use the excess power generated in the night.
On-grid solar systems generate power using a solar PV power system. These systems convert sunlight to energy, some of which may be consumed, and the excess power that is generated is sent to the utility grid. The owner of this system receives compensation for the extra power that was fed to the grid.
The hybrid solar energy system comes with the advantage of storing energy in the battery when the solar panel operates at its peak and retrieving the stored energy during peak evening hours when electricity rates are high or in case of any grid failure.
