The Capital Expenditure (CAPEX) model, also known as the Solar EPC model, allows businesses to own their solar power plant by investing upfront in the system. Under this model, Sun Photonics execute the complete Trunkey solution — from Engineering and Procurement to Installation and Commissioning — while the customer enjoys complete ownership of the solar asset.
This model is ideal for companies looking to maximize long-term returns, benefit from accelerated depreciation, and reduce energy costs by up to 80%. With no ongoing lease or monthly payments, the solar CAPEX Model gives you full control and savings for 25+ years.
Choose the solar CAPEX if you have available capital and want to turn it into a reliable, renewable energy asset.
The on-grid solar system connects to the utility grid, allowing you to export surplus energy, reduce electricity bills, and rely on the grid when solar power isn’t available.
The off-grid solar system operates independently from the utility grid, providing energy autonomy with battery storage, ideal for remote areas or places with unreliable grid access.
The hybrid solar system combines on-grid and off-grid benefits, using battery storage to store excess power and relying on the grid when necessary, ensuring maximum energy flexibility.
The Turnkey CAPEX Solar Model is most suitable for organizations that have available capital, a long-term sustainability outlook, and are looking to maximize financial returns by owning their solar energy system.
Below are some of the key business and industries that can benefit the most from the solar CAPEX model
Manufacturing units operate heavy machinery and production lines that consume a massive amount of electricity. With power tariffs rising, solar energy offers a cost-effective alternative. Solar for Manufacturing units with CAPEX model allows such industries to invest upfront and save lakhs every month while owning their power asset.
Why CAPEX Works:
Large warehouses often have vast rooftop spaces and minimal internal consumption, making them ideal for grid-connected solar systems under CAPEX. This model helps them reduce operational costs and improve energy efficiency.
Benefits:
Commercial office buildings with high lighting, HVAC, and equipment loads benefit immensely from solar installations. CAPEX allows corporates to demonstrate environmental responsibility while enjoying tax and long-term savings.
Why It Makes Sense:
Educational institutions have consistent power needs during daylight hours, making solar a natural fit. Through CAPEX, they can reduce expenses and reinvest savings into academic development.
Advantages:
Hospitals require 24×7 power for critical equipment. While full off-grid might not be ideal, a hybrid system under CAPEX ensures cost savings while providing backup through batteries.
Why CAPEX Is Useful:
These units consume power in irrigation, cold storage, packaging, and processing. Solar systems under CAPEX give them long-term relief from rising power costs and help ensure sustainable operations.

Explore MoreA CAPEX (capital expenditure) solar model is a turnkey arrangement where you pay all upfront costs to purchase, install, and own the solar system, while a single provider manages everything from design and permitting to installation and commissioning.
It makes things simpler because you only deal with one company. It can save you time and money, and you get experts handling the job, which lowers the chances of things going wrong.
One company takes charge of the whole project. They design it, buy all the stuff needed, install it, and make sure it's working perfectly before they're done.
Think of it like spending somewhere between ₹3.5 to ₹6 crore to set up a big solar power system that can power many homes. The exact cost depends on things like the quality of the solar panels and how much the land costs here in Gurugram.
It's like buying your own power plant. You own it, so you get to save money on electricity in the long run, and there might be some government benefits for going solar.
