How It Works

HeliCAL

HeliCAL is a Solar PV pre-feasibility report which provides valuable technical and financial information required for better decision making prior to investing in a Solar PV system. There are two types of reports.

OUR PACKAGES

Basic Report

The Basic package mainly helps in Site selection, planning and design of solar energy projects for any location across the world. The core of the Basic package is pvPlanner, a fast and highly accurate PV energy calculator tool for planning of a PV system at any location. It can compare PV output on the basis of different technology options such as module type, inverter efficiency, and mounting type allowing the user to assess a potential performance of a PV technology for any selected site or roof.

Basic package includes the following

  • Monthly and annual long-term averages of Global Horizontal Irradiation
  • Monthly and annual long-term averages of Diffuse Horizontal Irradiation
  • Monthly and annual long-term averages of Global Tilted Irradiation
  • PV Electricity Output
  • Air Temperature at 2m
  • Performance Ratio
  • Customized logo, etc.

Methodology

The pv Planner service is part of the SolarGIS energy assessment platform that serves historical, recent and forecast solar and meteo data worldwide at very high level of detail and accuracy. The SolarGIS methodology is based on using statistically aggregated solar and temperature data stored in the databse with a time step of 15/30 minutes. Solar radiation is calculated from IODC satellite data covering a period from 1999 to 2011. Derived solar parameters are calculated for any fixed-mounted or sun-tracking PV. Air temperature is derived from atmospheric models from ECMWF and NCEP. Simplified input parameters enable to consider key characteristics of a PV system, such as its position, geometry, type and mounting of modules, efficiency of inverter, and assumed losses in DC and AC sections. The model calculates reflectance losses at the surface of PV modules and losses due irradiance and temperature characterising operating performance of modules in a site-specific climate conditions. The other system losses, mainly at the DC and AC section are to be set by a user.

Premium Report

The Premium report covers all of the Basic plus it also includes system sizing as well as financial aspects which helps you instantly understand your system size and determine the economic viability of your Solar PV system. The Premium report includes

  • Basic package
  • System sizing – Determines the size of PV system, Inverters, Batteries, etc.
  • PV generation – Calculates amount of electricity your PV system will generate in a year
  • System cost – Calculates cost of your PV system
  • Internal Rate of Return (IRR) - Helps you evaluate whether the project is worth investing. You may even compare the IRR for the same project by selecting different technology options
  • Net Present Value (NPV) – Helps you analyse profitability of your investment by analysing the +ve or –ve NPV
  • Cash flow analysis - The cash flow statement shows how much cash comes in and goes out
  • Working capital – Calculates the amount of money needed to facilitate business operations and transactions
  • Debt Service Coverage Ratio – Helps determine whether your available cash flow is sufficient to pay current debt obligations
  • O&M expenses – Determines the Operation and Maintenance expenses of your project
  • Sale of Electricity – Determines income generated by Sale of Electricity which shall be potentially produced by your PV system
  • Return on Equity - Measures the ability of a the PV system to generate profits from the equity investments
  • Levellised Tariff determination – Determines the average fixed and variable tariff adjusted for inflation.
  • Payback period – Determines the time required for the amount invested in your PV system to be repaid by the income generated by the PV system

Methodology

System size - The basis for calculating system size is by finding out total load connected to it or by the daily energy consumption. Other factors such as Peak Sunshine hours, capacity of module, etc. are considered to determine system size. For Inverter sizing, factors such as total connected load, losses, etc. are used. However for battery sizing apart from a few others there are a number of factors such as system voltage, battery voltage, reserve time required, depth of discharge, battery loss, etc. are considered.

Financial Analysis - Most of the default financial parameters set are as prescribed by the Central Electricity Regulatory Commission (CERC) for India. However users have the option to enter their own parameters as per country of their choice.

So how does one Benefit from HeliCAL?

Rooftop PV system

Rooftop PV systems are usually installed by homeowners, industrial or commercial customers like residential buildings, SME’s, hotels, government buildings, educational institutions, etc. the size of which typically ranges from 1kWp to 500kWp.

To get your HeliCAL report, fill up a short form online and in a matter of a few minutes and get to know all that is required to install a solar system like the amount of solar irradiation at your rooftop, how much electricity your PV panels will produce, what size of panels you will require, cost of the system and other financial information such as rate of return, net present value, tariff, payback period, etc.

So get your HeliCAL, see if your roof is suitable, be energy independent and earn by selling electricity back to grid via feed-in tariff schemes (if applicable in your state) by installing Rooftop PV system.

PV Solar Farms

Solar PV farms can range from 1MW to as much as hundreds of MegaWatts or even GegaWatts. These Solar PV farms are generally owned by Electricity distribution companies (DISCOMS), private individuals or government and are usually worth millions of rupees of investments.

Before making such kind of investments it becomes critical to analyse a project from at least three angles; resource assessment, system sizing and the economic viability of the Solar PV farm.

This is where our HeliCAL report comes into action. Fill up your site address and a few basic details and get quick access to some important information such as PV system generation, system sizing, cash flow analysis, rate of return, net present value, levellised tariff, etc.

Banks / Financial Institutions

Banks/Financial Institutions play undoubtedly a key role in the growth of the Solar industry by providing investments to various categories and sizes of projects.

However prior to lending, banks / financiers require assessing whether the project is worth investing. Here is where HeliCAL’s Premium Report, a one stop solution in accessing a project’s viability comes handy by providing all valuable information such as IRR, NPV, DSCR ratio, payback period, levellised tariff, etc.
