Cost of installing Solar Rooftop System

There is a misconception that rooftop solar plant installation is expensive and only riches can afford. What is really holding back residential solar is the lack of knowledge with the process. People are still largely unaware of the financial incentives and attractive return on investment that taking up rooftop solar power solutions can achieve. When Greenpeace conducted a survey, nearly 55 percent of respondents indicated an interest in using the technology. However, the report also cited that many people perceive it to be an enterprise that requires large upfront capital investment, leaving this source of energy accessible only to the rich. Their misunderstanding or lack of enough knowledge led to their roofs not being installed.


Cost of 1  KW Rooftop P.V Plant

      Item                                            Cost (Rs.)                                       
Cost of a 1 kW rooftop solar plant   100,000.00
Subsidy @ 30%                                30,000.00
Net cost after subsidy                       70,000.00



Depending on the sunlight, 1 KWH would generate 3 - 4.5 units in a day. In a simple terms 1 KWH means 1000 watt per hour. In one hour, it generates 1 unit of electricity. Based on your appliances at your home or usage, you can decide, whether we want to go for 1 KW or more than that.
The estimation given above is approximate, it may go up to Rs. 20,000 to Rs. 25,000 based on panel quality. And battery capacity cost adds to the investment, if it is off-grid plant.

How to calculate your consumption - Take one year power bills and calculate how many units you consumed during in that year and divide that with 12 (12 months), you will get one month utilization. Again divide that with 30, you will get per day consumed units. Based on that you can decide the capacity of plant to install.

Maintenance

Proper maintenance maximizes the life span of your plant. An efficient and long-lasting P.V system will require a periodic check on system components.

  • Cleaning the panels in order to get rid of dust and other debris accumulated over time is compulsory 
  • Cleaning the panels can be done with  plain clean  water . You can seldom use brush. Chemicals should not be used to clean.
  • Check the panel in case of any dirt. If found, remove it. 
  • Check for any sort of cracks. Tracking systems needs to be lubricated with grease. 
  • Cables, mounting structures need to be checked for cracks and breaks.

Net Metering

Image
   Net Metering    is   a   new   concept   where   an instrument  which  has  a  special  metering  and billing  agreement  between  utilities  and  their customers,  facilitates  the  connection  of  small,renewable energy-generating systems to the power grid. This new  programme  is  being  developed  to  encourage  small-scale  renewable  energy  systems  to  ensure  that  customers always  have  a  reliable  source  of  energy  even  when  their renewable  generators  are  not  producing  energy,  and  to provide substantial benefits to the electric power-generating system as well as the environment. When  a  net  metering  client’s  renewable  generator  is producing more power than is being consumed, the electric meter runs backward generating credits. Whenever the net metering customer uses more power than is being produced, the meter runs forward normally. Net metering customers are charged only for the net power that they consume from the electricity service provider t

Solar Rotation Hanger

In cities, usually we will be little worried about drying clothes in our balcony. During winter and rainy, we try a lot to dry our clothes, turning them, changing to sunlight, fading out colour, if receives too much sunlight. Here we got a hanger rack that can be automatically rotated by solar power generation. Compared with traditional hangers, this hanger can greatly reduce the drying time of the clothing. It will sterilize the whole surface, eliminate bacteria, protect family health. An Innovation different way from traditional clothes drying method. It is a hanger rack that can be automatically rotated by solar power generation. Compared with traditional hangers, this hanger can greatly reduce the drying time of the clothing. It will sterilize the whole surface, eliminate bacteria, protect family health.   The hanger rack can rotate 360 ° to sunlight the laundry in all directions. Derived by rigorous calculation, It can reach 6 rotations per minute moderate rotation speed. Th

Solar Powered Tent

Solar Powered Tent for Campers:   Recreational camp­ing is all about communing with nature and spending time with your family outdoors be it in the park, at the beach or in the woods. To differentiate from regular life that make it count: Cooking over a fire instead of over a gas stove, sleeping under the stars instead of under a solid roof, carrying water on your back instead of turning on a faucet If you love outdoors and enjoy camping, you’ll agree that the tent is a very important equipment. It provides us shelter and most importantly, it gives power supply in your camping. Solar power is a common alternative energy source these days, and it's not just giant solar panels on buildings anymore. The U.S. military is developing flexible solar-panel fabric that can be used for tents and uniforms. And on the civilian front, you can use small, portable solar panels to power devices like cell phones, MP3 players and digital cameras -- and for indoor tent lighting, it turns out. Ther
