Solar Farm Solutions with Green Wattage:
Scalable Renewable Energy with No Upfront Investment
Large-Scale Solar Power for Businesses
As businesses worldwide push towards sustainable energy solutions, many are seeking ways to transition to renewable power sources. While rooftop solar is an excellent starting point, it often does not provide the capacity required to meet large-scale energy demands.
Green Wattage addresses this need with grid-connected, offsite Solar Farms through Open Access, enabling enterprises to procure up to 100% of their power requirements from solar energy. For instance, leading corporations leverage our solar farms to power their operations at lower costs while meeting sustainability commitments.
Opting for Open Access solar power offers businesses two key benefits: significant cost savings on electricity and an accelerated path toward 100% renewable energy adoption. Open Access solar allows enterprises to secure energy at competitive tariffs, ensuring price stability for the next 20-25 years.

Example:
Below graph showcases the benefit of procuring power from offsite open access solar farms in India. The Solar power is supplied considering the Time of Year (TOY) and with banking restrictions prevailing in India.
Let’s assume that this large corporate has a need for a continuous and constant power load of 100 units throughout the year 24×7.
Then power procurement through an open access solar farm alone can cater to only 60 units i.e. for every 100 units of electricity required only 60% of the power requirement can be substituted by solar energy without the risk of incurring significant banking losses and also customer can achieve around minimum 25% savings on their annual electricity bills.

FAQ
How does a Group Captive model work?
Businesses collectively invest in a Special Purpose Vehicle (SPV) to own a renewable energy asset while securing long-term energy savings.
What legal and financial factors should businesses consider?
- Ensure full compliance with equity ownership rules
- Verify economic participation rights
Can a business exit a Group Captive project?
Ownership transfer options, such as put/call agreements, must be defined in the PPA. Foreign-owned companies must adhere to RBI pricing guidelines for share transfers.
Assessing Solar Feasibility for Your Business
Before Green Wattage can design and install a rooftop solar power system for you, it’s essential to evaluate whether your site is suitable for such an installation.
We provide end-to-end solar solutions, managing everything from design and installation to long-term maintenance, so you can focus on your business operations without any hassles. All you need is an unused roof, and we’ll take care of the rest. However, before moving forward, here are some key feasibility checks to consider:
Shadow-Free Area
Ensure there are no obstructions such as trees, adjacent buildings, or billboards that could block sunlight.


Cleanliness & Maintenance Accessibility
The site should be free from excessive dust, pollution, or debris that may hinder solar panel efficiency.
The rooftop should be easily accessible for regular cleaning and maintenance.
Structural Capacity
Your roof must have adequate load-bearing capacity to support the solar system. Reinforcement may be required if the structure is not strong enough.

Our expert engineers at Green Wattage conduct a detailed site assessment to ensure your rooftop solar system meets all safety standards and regulatory requirements. We design innovative solar solutions that optimize efficiency while adhering to compliance norms.
Whether you are looking for rooftop or ground-mounted solar solutions, Green Wattage delivers top-tier solar energy solutions, helping businesses across India and internationally with sustainable energy alternatives.
