Solar photovoltaic modules are also referred to as solar PV modules that convert sunlight directly into electricity. Solar PV modules are different from the solar thermal collectors which are used as solar water heating systems.
A solar PV module helps reduce carbon emissions and significantly cuts down your electricity bill by the use of sustainable energy to produce electricity.
The conventional electrical grid network is not always reliable due to issues with overloading, severe weather including maintenance or upgrades.
A PV module allows you to create your electricity to supply your entire home or business and can potentially eliminate the issues associated with large utility grids. The range of electricity generated is dependent on factors like the size and arrangement of the PV power system, the available sunlight, and the efficiency of the electrical components used to convert solar energy into electricity usable by your home or building.
Types of PV Modules and How They Work!
Grid-connected PV Module
The grid-connected solar photovoltaic (PV) system is a common and cost-effective option to reduce electricity bills and emissions.
- Cost-effective option
- Generate your own renewable energy on-site
- Supplement your electricity needs from the local utility grid when the PV system is not supplying enough energy
- You can also export excess electricity back to the utility company when the PV system is generating more electricity than you need during daylight hours.
- The way this exported electricity is metered and the rate of financial return varies by country, state, local district, and utility provider.
Grid-connected PV System with Batteries
Grid-connected PV System with Batteries is a module which gives you the best of both worlds. PV modules in this system have used a charge a battery bank during the day.
- You can export electricity from your battery bank.
- Use the electricity from the grid during periods of high use.
- You can configure the system to supply DC loads from the battery bank.
Off-grid PV System
This module is best applied in remote locations, and other areas not covered by the main power grid. The PV modules generate electricity that is used to charge batteries during sunlight hours. It can then power DC loads directly or provide to the AC load through the inverter.
- *Can be extensively applied in remote locations, and areas not covered by the main power grid.
- *Power of the DC load can directly be provided to AC through the winter.
- *Provides independence from the utility grid depending on the size of the loads that can be supplied by batteries and inverters.
