Benefits

Solar Powered water pumps are ideal for agriculture and related activities and are a great alternative to conventionally powered systems. They are highly reliable, low on maintenance and easy to install and operate. They are also eco friendly and reduce the dependence on fossil fuels. As most farms and agricultural setups are established over large areas which are mostly inaccessible and remote, reliability of the system becomes critical. With the proven reliability of the solar water pumps farmers and owners can be rest assured of an uninterrupted performance. With power supply at times not being consistent solar powered pumps will provide continuous pumping through out the day on most days. They have proven to be a great addition to a modern farm looking for a reliable system to ensure that one of the most important elements "water for the plants" is at all times supplied.

Subsidies

Under the JNNSM off-grid policy, under certain conditions, the MNRE provides subsidies @ Rs. 81/Wp to offset the capital cost of the project. The MNRE recently revised this capital subsidy and benchmark cost of SPV systems on April 1, 2011. Please click, download, and understand your options by from:

Revised Capital Subsidy and Benchmark cost of the SPV system.pdf

So, for a 10 kWp with one-hour battery back-up, the Rs. 27 lakhs capital costs (@ Rs. 270/Watt) will be offset by Rs. 8.1 lakhs or only Rs. 18.9 lakhs (Rs. 270/Watt – Rs. 81/Watt = Rs. 189/Watt) or about a 30% discount.

Solar-Apps will take care of the entire process for you. We will provide you with a free needs assessment and based on your project configuration measured in kWp, we offer a simple fixed-price model in slabs of 20 kWp, 80 kWp, 400 kWp, and 500 kWp.

For projects that meet the minimum criteria set forth by the MNRE, our goal is to hand over the subsidy in two installments within 6-months or your money back. How we do this is through a strategic tie-up with MNRE channel partners that are CRISIL 1A certified. Knowing where your money is coming from as well as the control is always promises to be a less stressful option.
