FAQ

What are the Benefits of rooftop solar power plant?

A PV power plant can make the facility go off grid. A grid tied or hybrid system can reduce the dependence on state power grid.

What are the electrical appliances that can run on solar?

A well designed solar PV system can run any electrical equipment running on the grid. However it is economical to migrate the low power appliances on solar.

Do we get enough power during cloudy and rainy days?

The Grid tied / Grid interactive systems are also connected to the grid. If the power produced by solar is not enough for the House/Industry, deficit will be taken from the grid. For off grid solar systems the battery and array will be designed for the worst conditions hence the system will be able to supply uninterrupted power.

What is a Hybrid and grid interactive System?

Hybrid system is a smart system involving, solar, grid and diesel generator (DG). Here, Solar takes the first priority to run the loads. Excess power generated will charge the battery bank. During night battery will support the loads till a safe battery voltage. System will switch over to grid automatically below battery safe voltage. If GRID is not available and battery has been discharged, PCU can command DG to start and supply power to the loads till Grid or solar is restored. Hybrid systems can also be configured as grid interactive systems where only solar and grid are present. Here, the first priority is given to solar. Excess power generated will charge the battery bank. During night battery will support the loads, till a safe battery voltage. System will switch over to grid automatically below battery safe voltage. This would extend the battery life and provide seamless power supply. There will be no power exported to grid.

What is a Grid tied System?

In grid tied systems, the system is interfaced with the state power grid. Here, Solar takes the first priority to run the loads. The excess power, if generated ,will charge the battery bank. The excess from the battery bank is fed into the state power grid. Grid tied system can also be configured without a battery bank.

What is an Off-grid system?

Off Grid or stand-alone system refers to being independent of the state grid. The design would support all the loads and sufficient back up would be provided to cater the power needs under worst conditions. One can go off-grid for low intensity loads. In other words, all equipments having a power rating lesser than 500W can be taken off grid.

Can i integrate my DG with Solar?

Our hybrid solar systems can be integrated with the DG. The system can switch on or switch off the DG depending on the power requirement.

What is the life of Solar PV System?

Solar Panels can last for more than 25 years with 80% efficiency. The Inverters can last more than 10 years and the batteries will last for an average of 4 - 5 years.

How much energy can be generated per unit area?

3 Units of power (3KWh) of power can be generated from 100 Sft of non-shadow area.

What are the Safety precautions to be taken after installing solar PV Power Plant?

The Area around the inverter must be kept well ventilated. The area around the battery should be well ventilated. No metal objects should be stacked near the Battery or the inverter. Battery bank and inverter must be kept out of children's reach.

Can we install Solar Panels on Pitched roof?

Yes we can install solar panels on pitched roof. We specialize in mounting of solar panels on sloped roofs.

Can the solar system be upgraded for higher power after installation?

Yes additional solar panels can be added to the system. However the inverter has to be sized initially.

Will the roof be disturbed after installations?

No, the mounting structures are non penetrative.

How much carbon dioxide emission will be reduced by Solar Power Plant?

About 1.65 tons of CO2 emission per year can be reduced by having a 1KW system.

What is the maintenance required for solar power system? Two keys maintainence are required. 1. The solar panels needs to be cleaned very regularly. It is advised that the panels are wiped/cleaned every week. 2. Distilled water/acid must be topped up to the battery once in 6 months. What will be the additional electric equipments required for Grid Tied/Grid Interactive System?

Grid tied systems need additional meter for measuring the power exported to the Grid. Also for safety requirement a lockable switch accessible to the grid maintenance technician will be provided. Grid interactive and grid tied systems will also have a change over MCB switch for safety and easy changeover between grid and solar power.

How to protect the solar Panels from Theft?

Solar panels can be interconnected with hardened steel cables and locked for additional safety.
