What is Solar Energy Consultancy?

Solar Energy Consultancy Approach

Solar Energy Consultancy Approach and Process

Solar Energy Consultancy is about understanding all the crucial aspects of Solar Energy before making strategic decisions on the subject. Decision making about Solar Energy project happens at every stage of the project. Irrespective at what stage you are at your Solar Energy project you need a Solar Energy expert to ensure the success of your Solar Energy project.

Why Solar Energy Consultancy?

Solar Energy specifically PV Solar has been active in India since 2010 and is gaining momentum with every year since then. As on 31st March 2019 approximately 28 GW (28,000 MW) cumulative Solar installation has been done in India so far which includes Utility + Rooftop. Majority of these installations have been on Utility scale but that situation is slowly changing as rooftop projects are becoming increasing viable. The utility scale projects consists of big players which either have a good experience or hire external experts to ensure project quality and execution timeliness. However the rooftop space has several players with new and experienced players alike. It is thus no surprise that majority (nearly 70%) of such projects are generating lesser than designed or expected power. Also many projects are stuck up due to delay in financial closures., primarily BOOT / OPEX projects.

We carried out a study of 50+ Solar Energy installations across India and identified several issues. The key points observed during the study of Installed Solar Energy Projects are :

  1. Technical issues with engineering and design aspects leading to performance issues.
  2. Lack of technical due-diligence resulting in performance issues (including vendor selection, technology suitability, factory visits, material handling etc.).
  3. Site related issues primarily with respect to shadow analysis, weather conditions, roof strength etc.
  4. Limited information on availability of various financial models available leading to re-financing or off-taker dissatisfaction and even re-negotiation.
  5. OPEX / RESCO PPAs not properly framed considering all possible future scenarios including (but not limited to) technology upgradations.
  6. Operation and Maintenance not effectively carried out resulting in lesser than possible generation.
  7. Lack of Safety measures which may not directly impact output but can challenge project durability and longevity.

Major issues observed :

  1. Selection of technology which may not be suitable as per site conditions.
  2. Absence of a domain expert within the plant team to ensure project quality and viability.
  3. Little or no due-diligence carried out before finalizing project.
  4. Lack of awareness about financial models and variety of technologies.
  5. Impact of a variety of techno-commercial parameters.
  6. Project delays.
  7. Framing of legal contracts.
Etc.

As can be seen in the following sub-section how the following 4 areas have evolved viz. Technology, Commercials, Financials and Govt. policies.

Technology
  1. Improved PV modules – variety of technologies + introduction of new technologies + enhanced capacities + ongoing R&D.
  2. Enhanced efficiency of Inverters for better generation.
  3. Advent of newer monitoring and trouble-shooting systems.
  4. Enhanced engineering and design practices.
Commercials
  1. Falling cost of PV modules and other components
  2. Tier-1 Companies vs non-standard
Financials
  1. Ease of financing with a variety of financial models
  2. Improving IRR or RoI
Govt. Policies
  1. Moving from subsidies to self-sufficient units by allowing net-metering
  2. Single window clearance (some States)
  3. Tax benefits such as 40% Accelerated Depreciation

Going for a Solar Energy Photo Voltaic Project is a strategic decision as the project has a life of 25 years. There are tremendous opportunities in the Solar field but dynamic market requires constant monitoring by an expert before making this strategic decision and during the project execution. It is thus imperative for a Company to engage a professional consultant or a consultancy firm to ensure Project quality, reliability, longevity and durability.

  • A. Pre-project Solar Energy Consultancy

  • B. Solar Energy Project Consultancy

  • C. Post-project Solar Energy Consultancy (Solar Project PRS Audit + O&M)

Practically everything about Solar Energy in general and Solar Photo Voltaic (PV) in particular. Solar PV, although relatively new in India, is widely used globally to generate power. In fact Germany which does not receive adequate Solar radiation is the leading generator of Solar Power through Solar PV.

India, a Solar-rich Nation, is now waking up and will not take long to realize the true potential of Solar Energy. Solar Energy needs to be harnessed and is truly the answer to India's power problems of power deficit and sustainability with growth. Although Solar Energy alone could not be the solution, but PV Solar will certainly contribute in a very big way to solve the Nation's Power and Energy related problems.

A. Pre-project Solar Energy Consultancy (Solar DPR, TEFR)

Understanding about your Solar Energy project before actual execution is of utmost importance. This considering that going Solar is a strategic decision as Solar Energy project has a life of 20+ years. Majority of the decision making like technology, project sizing, financial model are to be taken BEFORE PROJECT EXECUTION or PLANNING. Our Pre-project Solar Energy Consultancy Package including Technical and Advisory Services is a critical step in that direction.

As part of our Solar Energy Consultancy Package, we attempt to get you the answers to the following queries :

  1. What exactly is Solar Energy Photo Voltaic (PV) technology and how does it work?
  2. What are the various technologies in Solar PV and which is the most suitable for my site?

  3. How much capacity could be installed at my site and challenges associated with each installation, if any.
  4. How much output can I expect in terms of kWh per month and kWh per annum for PV Solar Installation?
  5. Is my location ideally located for Solar Power? (In general 90% of the Country is suitably located to utilize Solar Energy, the output may vary from one location to another).
  6. What will be the cost of installation of a PV Solar system and payback period.
  7. What are the various Government incentives and subsidies? Will my project be eligible for these subsidies?
  8. Debunk popular myths and miconceptions about Solar Power including working in cloudy or foggy conditions, battery operations, grid synchronization etc.

The study concludes with a detailed Solar Energy Report either a DPR (Detailed Project Report) or a TEFR (Techno-Economic Feasibility / Viability Report) which is prepared after the visit and forms the basis of all future decision making.
