Amidst power shortages and power cuts, every year you think of setting up a solar pv system in your house and something pulls you back. It may be lack of knowledge about solar pv that may be stopping you. With this video we want to provide you with some knowledge that can help you take the first steps. Here are some key points First: What is solar pv system? Solar PV is semiconductor material that takes light from sun and converts it into electricity. Please note, light is very important for it and it generates more electricity when light is more and less when light is less. Solar PV system includes Solar Panels, charge controller, inverter and batteries if it is an offgrid system. Second: What are various types of systems? There are two types of systems: off grid and grid connected. In off grid systems all the electricity generated is stored in battery and is used locally. While in Grid Connected system there are no batteries. Some electricity generated is used and extra generated electricity is sold back to the electricity distribution company. Please note: If you have an existing electricity connection electricity can be sold to grid only if your state has a netmetering policy. Third: How much does a Solar PV system Cost? A 1 kW system that can generate 4-5 units of electricity a day costs about 1-1.25 lakhs for a off grid system with batteries. A similar sized grid connected system would cost about Rs 75000-90000. Fourth: How much area do I need for 1 kW system? You need about 80-100 sq ft area for 1 kW system generating 4-5 units of electricity. If you have a larger area on your rooftop then you can accordingly adjust more capacity. Fifth: How do I identify the size of the system that I need? Your best bet is your electricity bill. Look at your electricity bill and see you maximum daily usage in any month across the year. That can give you the idea on number of units you consume per day. And do remember 1 kW system can generate 4-5 units a day. Sixth: Can I use Solar PV with my existing inverter battery system? You can certainly use your existing inverter battery system with solar pv. These days solar conversion kits are available in market that charge the batteries from solar when possible and when solar is not available it charges the batteries from electricity from the grid. This way you can take benefit of solar as well as use the grid when there is no sufficient light outside. And last point for this episode: Are there subsidies available for solar? Subsidies are available for solar through various central and state government schemes but they are hard to get as there is a priority list for approval. Establishments of common use like educational institutes, hospitals, etc are higher on priority list than residential setups. MNRE advices people to setup rooftop projects without waiting for subsidies as there are constraints on availability of funds. Finally a word of caution: The market is flooded with cheap bad quality products that may not last long, so please check for certifications of quality before buying. This was the first video in series for solar pv. So keep watching for this space.

मेरे भाई
1 watt सोलर सेल का दाम 18 rs हे तो 1 kw का 18000 हो गया 2 kw का 36000। आपको 18 rs मे सीधे नहीं मिलेगा लेकिन दो चार जगह दाम पुछना पड़ेगा आप इंडिया मार्ट का इस्तेमाल कर सकते हो और इसको आप on grid लगाना पड़ेगा औए सोलर पेनल थोड़ी सी मसकात से बनाई जा सकती हे youtube पे इसके भाई vidio भी हे दिल्ली जयपुर और सूरत मे कई सोलर सेल बेचने वाले हे जिससे आप inq कर सकते हो 75 हजार मे ongrid सोलर सिस्टम बन सकता हे - जय हिन्द -
