1 KW Roof-Top Solar PV system

The Solar Photovoltaic system installed in this zero energy model building is of 1 kW capacity. The system is designed to support total connected load up to 3 kW. 

Electricity generated through coal plants is becoming expensive by every passing day. Power cuts and increasing dependence on DG sets is causing a lot of damage to the environment.

Keeping this in mind Ministry of New and Renewable Energy (MNRE), Government of India is promoting off-grid solar PV systems under the Jawaharlal Nehru National Solar Mission in the country. Many people in the country have started feeling the need of installing solar PV system for their home, apartment complex or small office use, and with this article we would try to provide some information which can be a good starting point for a roof-top Solar PV system project.

Components of a Roof Top PV system

A typical Roof Top PV system also contains a set of batteries and inverter along with the modules of Solar PV cells. The overall efficiency of the system will also depend on the type of battery and inverter used in the system.  It is important to choose the right components for most effective use of Solar PV systems.
 A 1 kW solar roof top could be set up in an area as small as just 100 square feet.
This could be used to energise 2 tube lights, 2 fans, and even a fridge. Leave alone these appliances, you could even run your air conditioner with 1 kW solar panel, provided you do not use it for anything else.
The cost of installing a 1 kW solar panel could be between Rs 1 lakh to Rs 1.5 lakh complete with a battery and an inverter. MNRE provides 30% capital subsidy on capital expenditures for rooftop solar systems for both commercial and residential entities for systems up to 100 kW. The government also provides loans at 5% per annum for 50% of the capital expenditure for 5 years tenure for both commercial and residential entities. Commercial entities can claim either capital or interest subsidies.

India's first electric bus starts running in Bangalore

 India's first electric bus has started running on Bangalore's roads. The route on the busy Majestic-Kadugodi road in Bangalore has India's first electric bus. The city's transport corporation launched this bus last week.
Zipping past the smoke-emitting regular buses, the orange beauty stands out. "The pollution level is quite high in Bangalore. So we were exploring the options of hybrid as well as electric buses. A Chinese company - Build Your Dreams - came to us and told us that they wanted to give this bus free of cost for trial," said Anjum Parwez, Managing Director, BMTC.
The electric bus will run on a trial basis for three months after which hopefully, it will be a regular feature on Bangalore roads. The bus has zero emission levels, operates on a battery that lasts five hours and can cover a distance of 250 km.
"It is much better than driving regular buses. I feel very proud to drive the first electric bus," said bus driver Ramaswamy.
Fitted with CCTV cameras, the bus also has a disabled-friendly design. But these buses don't come cheap. Bangalore's transport corporation is hoping to get financial aid from the state government in the months to come.
Bangaloreans have many reasons to smile as there's a new metro line and of course the electric bus. And such eco-friendly transport initiatives will help in bringing down the pollution levels in Bangalore and hopefully set an example for other cities.
