- What is a photovoltaic (PV) system?
PV technology produces electricity directly from electrons freed by the interaction of sunlight with a solar panel made of semiconductor material. The power provided is direct current (DC) electricity. The basic building block is known as a Solar cell. Many cells put together are known as a module, and many modules assembled together form an array. A PV system will consist of an array of modules generating DC electricity, an inverter and can be stored in battery storage banks.
- Are the solar PV panels fragile?
Solar PV panels manufactured as per National and International standards are robust and can withstand the normal stresses subjected by nature.
- What are the components of a photovoltaic (PV) system?
A PV system is made up of different components. These include PV modules (groups of PV cells), which are commonly called PV panels; one or more batteries; a charge regulator or controller for a stand-alone system; an inverter for a utility-grid-connected system and when alternating current (ac) rather than direct current (dc) is required; wiring; and mounting hardware or a framework.
- What is an inverter?
Majority of electrical equipment’s used for domestic/commercial/ Industrial purposes are of AC system. So, it is necessary to convert solar power generated at DC system to AC system. An inverter will convert DC to AC system.
- What is a “grid-tied” PV system?
Connecting your solar system directly into the utility ( Your Electricity supply Company )
- What are the different types of rooftop solar PV systems?
- Grid Connected – These systems have no storage other than the grid itself. Any excess electricity generated from solar system is fed back into the grid. At night or during times of intense cloud cover, the installation draws power from the grid.
- Hybrid (Grid tied with Storage) – These systems are grid connected, but also have some storage capacity by way of a small battery bank. They provide some measure of continuity when the grid goes down at the same time as there is not sufficient solar input.
- Off-grid – These systems are suited to remote locations where a grid connection is not available/when there will be no continuous power supply in the grid. The battery bank is sized to provide a certain number of days of storage in the installation and the installation draws power from the storage batteries during the night or during days of intense cloud cover.
- Can I use Solar PV system to power my home?
Solar PV system can be used to power your entire home’s electrical systems, including lights, cooling systems, and appliances.
- What is net-metering?
Net-meter (bi-directional meter) is having provision to record energy imported from the grid to meet the load and energy exported to the grid after self-consumption. Both energy import and export records in the net-meter. The difference between Export and Import readings is the actual energy consumed/delivered.
The net meter records surplus energy exported to utility grid. When your system generates less energy than your consuming load, the meter records energy imported from utility grid.
- What guarantees will I receive?
The SPV GT system will be normally having 25 years of guaranteed life and same is guaranteed by us 25 years for PV modules and 5 years for Inverter.
Utility company will sign a Power Purchase Agreement with Solar rooftop PV generator which will be in force for 25 years.
10. How much space on my roof do I need for a solar PV installation?
The grid connected SRTPV system of 1 kW peak power capacity requires about 100 sq. ft. / 10 metre square shadow free area on the rooftop.
11. How much electricity does a PV system generates?
For every kW peak SRTPV system installed on a South facing roof, the system will generate 4 to 5 units per day. However, the energy generation depends upon the weather conditions and reduces by around 20% for an East or West facing roof.
