India Solar Hackathon is the first of its kind. Powered by New Energy Nexus*, a global clean energy startup network, it will bring together developers, solar experts, accelerators, designers, students, government officials and investors to solve real world solar challenges. 

Why is solar a software challenge? Because technology and the cost of renewables are no longer the main limitation to providing clean electricity for billions of people. It's the absence of innovative business, finance and service models that hinder its deployment. Following the VC investments, we see the shift is real from solar hardware and materials to software.

At India Solar Hackathon, the goal is to develop new solar software technologies, and to create new startups for funding, while jump starting winners with INR 3,00,000 in cash prizes. Yes, in just over 24 hours. 

So come be a part of the nation’s most innovative industry at India Solar Hackathon on November 11th and 12th and change the face of solar.

Get your ticket and register on DevPost before it's full to capacity.

*New Energy Nexus is a program of the California Clean Energy Fund.

Nexus Challenge 1: ‘Educational portal for residential solar’

Design a portal to educate residential users about the benefits of solar energy. Show innovative applications for solar panels. Include a comparative analysis of PV technologies. Try to improve engagement with gamification.

Nexus Challenge 2: ‘App-based automated solar system size and cost/payback generator for rooftops’

Design an app for sizing, daily generation profiles and back-of-envelope savings, based on limited user-inputs on roof area and location (city). The user experience should be designed to be intuitive and engaging.

Nexus Challenge 3: ‘Automated solar potential mapping for cities’

Create a software architecture for geo-mapping rooftops (using GIS/Drones inputs) in a dense megacity to get true PV potential. Identify and geo-mark vacant roof spaces and parking lots (C&I and residential) where solar could potentially be installed (and enable extraction of coordinates in spreadsheet form).


Enphase Challenge 1: ‘Help Enphase engage commercial solar users’

As India catapults its way toward its ambitious renewable energy target, commercial scale solar will be a major driver in achieving this. Using Enphase Energy's Enlighten platform, find an engaging way to promote the benefits of smart solar to the commercial market.

Enphase Challenge 2: ‘Engage people with solar using cricket!’

Enphase LOVES smart solar and India LOVES their cricket. Find a way to combine the two to help the Indian public engage with and get excited about smart solar.

SAM SDK               

The SAM Simulation Core (SSC) software development kit (SDK) is a collection of developer tools for creating renewable energy system models using the SSC library.

PVWatts Online                                  

PVWatts is widely used by industry and the public alike to estimate the energy production and cost of energy of grid-connected photovoltaic (PV) systems throughout the world. It allows homeowners, small-building owners, installers, and manufacturers to easily develop estimates of the performance of potential PV installations, providing an estimate of hourly, monthly, and annual PV system production using a rooftop drawing tool and simple analysis options.

PVWatts Online API        

API links for PVWatts

NREL API Database

NREL Solar Documentation         

Access data and analysis services that provide access to solar resource data and NREL models.

Enphase Enlighten Systems API

Enphase API quickstart guide (for those working on the Enphase challenges). It contains everything they will need to build an app that is compatible with Enphase, including sample data.
This API delivers energy production data from PV systems that use Enphase microinverters. A subset of these systems are available for use during the hackathon. (  



Who can participate?

Anyone over the age of 18 who meets the minimum eligibility criteria as per below (don't worry, if you have 5 months of experience instead of 6, we'll be willing to consider - get in touch!)

Is my registration/ticket transferrable?

Yes - but please inform us in advance along with details of the person to whom it is being transferred to

Do I have to be part of an existing team to apply?
