Solar Mango DPR for Solar Power Plants

Are you looking to invest in a solar power plant in India?

Use Solar Mango’s Detailed Project Report for Ground Mounted Solar Power Plants to understand everything about this fast-growing opportunity.

With solar power growing at a fast pace in India and with the central state governments providing significant thrust and incentives for its growth, thousands of entrepreneurs, investors and businesses are keen to invest in solar power plants. This is a detailed project report for them.

This comprehensive expert report and guide will be invaluable for those investing in the ground-mounted solar power plants business in India.

Solar Mango’s Ground Mounted Solar Power Plant DPR, in addition to providing detailed inputs on the business models, financials, technology, and details on land and infrastructure required for implementing a ground mounted solar power plant, also includes important sections on risks and risk mitigation where it clearly spells out the areas of uncertainties, and how adverse effects of each uncertainty can be mitigated.

This Detailed Project Report for Ground Mounted Solar Power Plants is written by industry experts from Solar Mango with experience in technical, operational and financial aspects of the Indian solar energy sector.
Our team has assisted over 50 companies in their solar power plant investments, and over 1000 Indian companies and entrepreneurs in understanding the solar power plant business.

This detailed project report can be used by your corporate project teams for internal presentations. In addition, it can also be used as a key reference resource for making the DPRs for banks or other financial institutions.

As you will be investing significant amounts in a solar power plant (1 MW of solar power plant costs upwards of Rs 5 crores as of Apr 2016), it is imperative that you are able to review a document that provide authentic and comprehensive details on all the critical aspects of a ground mounted solar power plant. As a result, both internal corporate boards and external financial institutions recommend that you get the DPR done from an expert organization and not a company that just writes a Protocol DPR report. Just to let you know, we have seen DPRs that are nothing but copy-paste of some Internet pages. It is critical you avoid such DPRs.

Solar Mango is the leader in the solar energy research, consulting and education domains for the Indian market.

This DPR, in addition to providing detailed inputs on the business model, technology used, land and location details and financials, also includes sections on risks and risk mitigation that clearly spell out areas of uncertainties, and also how the adverse effects of each uncertainty can be mitigated. Give special care to this section of Risks and Risk Mitigation, because this is how you clearly prove to your board or to your external financial investor that your professional team knows what exactly it is doing. Banks and financial institutions do take some risks, as long as they understand the nature of risks involved, and where possible, having a metric to quantify those risks.
