Solar energy is the emerging source of renewable and sustainable power which through the grid tie installation, allows you to exploit every ounce of sunlight that hits your panel.
Where other systems sits idle (like a solar water heater or an off grid system) your inter tie system constantly generates even when you are not using any appliances. It has become such an important concept that the central government through the ministry of new and renewable energy (MNRE) has started legislating the state electricity boards to allow the solar producing customers tie to their grid and provide incentive either in form of energy credits or in form of financial credits. Energy credits in form net-metering is proving to be the most popular as it allow the state electricity boards to fulfill their renewable purchase obligations(RPO) easily and the customers with all the benefits of grid tie systems.
Total Solar Power in GWp: 748.98 GWp
• In Madhya Pradesh, 61.66 GWp
• India's solar power potential estimated at 749 GW while the tapped solar power output is still under one percent. Study by Deloitte and Confederation of Indian Industry (CII) - 24 Aug 2015.
• Solar Resources Bhopal: (23°15′N 77°25′ E) - 1729 kWh/m2/year approx.
• The global solar radiation over India varies from 4-5.5 Kwh/sq m/day.
On grid systems have the upper hand amongst the above mentioned because the tangible benefit that you expect directly impact your finances (unlike off grid system). They are more efficient and low cost as you eliminate the storage system (battery). Keeping it simple an on grid system gives you three fold advantages-: Firstly you have increased efficiency as batteries (storage facility) require constant charging. When fully charged a charge controller disconnects the system in off grid modules. In hybrid systems too, the efficiency of the battery, constant need of charging pulls down your optimum system performance.
Secondly, battery (storage device) is a maximum of 5 to 7 years add to that frequent maintenance, charging in efficiency, risk associated with a container that coverts chemical to electrical energy , security and safety concerns etc. your system life and safety both take a downward slide.
Thirdly, cost of the system is drastically reduced. Not only you reap more benefits with an on grid system, but you start saving on your money at a lower cost of equipment.
Installing a full scale photo voltaic system is considered the best solar investment counting the fact that you can instantly neutralize your entire electricity bills and also reduce your carbon footprint. A grid tie solar PV system makes the most economic and environmental sense.
