What is solar power system?
Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV), indirectly using concentrated solar power, or a combination. Photovoltaic cells convert light into an electric current using the photovoltaic effect.
How do solar panels work for your home?
Solar panels work by absorbing sunlight with photovoltaic cells, generating direct current (DC) energy and then converting it to usable alternating current (AC) energy with the help of inverter technology. AC energy then flows through the home’s electrical panel and is distributed accordingly. Here are the main steps for how solar panels work for your home:
- Solar panels absorb the sun’s energy and convert it to DC electricity.
- The solar inverter converts DC electricity from your solar panels to AC electricity, which is used by most home appliances.
- Electricity flows through your home, powering electronic devices.
- Excess electricity produced by solar panels is fed to the electric grid.
TYPES OF SOLAR SYSTEM/DESIGN
1. ON GRID
No requirement of battery bank.
Surplus energy fed back to the grid
2.OFF GRID SYSTEM
This design is used where no availability of electricity.
Battery bank is required for the backup at night.
3.ON GRID HYBRID SYSTEM
Requirements
Battery bank,net metering device
Surplus energy fed back to grid
4.OFF GRID HYBRID SYSTEM
Requirement
Grid connectivity, battery bank
Solar Power Advantages
- Solar power is pollution free and causes no greenhouse gases to be emitted after installation.
- Reduced dependency on foreign oil and fossil fuels.
- Renewable clean power that is available every day of the year, even cloudy days produce some power.
- Return on investment unlike paying for utility bills.
- No maintenance as solar panels last over 25 years.
- Excess power can be sold back to the power company if grid bidirectional meter is installed
- Ability to live grid free if all power generated provides enough for the home / building
- Can be installed anywhere; in a field to on a building
- Use batteries to store extra power for use at night
- Reduce the mineral consumption.
