The CAPEXP model in roof top solar

If you are looking to cut your electricity bills or your carbon footprint, using renewable sources of energy is the place to start. If your business premises offer ample space for installing a solar power plant, and you are willing to make the upfront investment in owning a solar power plant, then a solar EPC (Engineering, Procurement, and Construction) or Capex Model is the answer to your needs.

The heart of an efficient roof top solar plants lies in the detail of its ENGINEERING design: We begin by understanding your requirements, conducting a site survey and monitoring the weather conditions. Our engineering experts then determine the appropriate power generation capacity for your site, select the appropriate equipment, complete the engineering design, and finally integrate our proprietary digital operational and maintenance platform for the proposed solar power plant.

Procurement: Once the engineering has been approved and accepted ,components are sourced from our approved suppliers, whom we use for our owned projects as well. As your one-stop solar EPC contractor,  our job is to ensure sourcing the best-in-class equipment to fulfill your power needs.

Solar plant construction : 

From mounting solar PV modules and connecting the solar power system to your existing electrical infrastructure, our engineers will construct and assemble the solar solution which is customized as per site requirements. post installation the client acceptance testing is performed as per the agreed SLA.

Operation & Maintenance services

We monitor our large portfolio of rooftop plants continuously, to ensure maximum performance and minimal downtime. The maintenance contract will ensure that our IoT powered solution is  monitoring the solar plant 24×7 so that the system runs efficiently through its lifetime, offering you uninterrupted service and maximizing your solar plant’s performance.

Our turnkey EPC solution includes the entire project, right from studying site feasibility, ensuring the highest standards of quality and safety, to the final plant commissioning. This also includes managing the complete operation and maintenance of the solar plant through a 24×7 remote proprietary monitoring solution for the first year .

How ever if you feel that Capexp is a constraint you can choose a suit of Opexp based packages we have by which you pay only for the consumption.

The advantage of  Wind + Solar + Storage

At the forefront of renewable energy development is solar power and wind power. Again, neither hold the answer on their own but collectively the two compliment one another nicely. The third, and critical element of this equation is energy storage, where again, there have been considerable improvements made in recent years, with significant headroom for future development.

Due to limited sunlight hours during the day, a solar system designed to provide 24 hours worth of power must generate that in approximately 1/5 of the day. Therefore, the system would need to generate enough power in ~5 hours to last 24, with the ability to store at least 19 hours worth of energy.In fact, when a wind machine is added to a solar system, the size and cost of that solar system and its storage system will be reduced to a point where the savings equal or exceed the cost of the wind machine.

To illustrate this point, if we look at a hypothetical model that needs to generate and deliver an average of 20+ kW per hour, or approx 500 kWh per day, here are a couple potential scenarios using just solar + storage, and solar + wind + storage:

In the solar + storage scenario, the solar system would need to make 500 kWh in 5 hours, and therefore, must average over 100 kWh per hour. At 250 watts per panel, this amounts to 400 panels at $300 each = $120,000. ( USD) ( Please do mail us at for computations made for Indian projects)

Assuming this is an off-grid installation, all of the power would need to be stored so it can be released overtime, including after the sun goes down, as the demand requires. Therefore, at $500 per kWh of battery of storage, 500 kWh = $250,000

If a wind machine provides 20% of the power needed over the 24 hour cycle, then the cost of solar and storage can be reduced by 20%, or 20% of $370,000, which amounts to $74,000. This is the calculus when the wind speed is low and the wind machine is only making 4 kW per hour.

If the wind speed increases from 5.4 m/s (12 mph) to 7.2 m/s (16 mph), the wind machine will produce ~8 kWh or ~200 kWh per day.

The calculus is better and results in a 40% reduction in the solar system and storage. In this case, a single Uprise wind machine that costs $80,000, will reduce the cost in this model by 40%, which is equal to $148,000, much more than the cost of the wind machine.

:There are other benefits of a hybrid system : 

When combining solar, wind and storage, there are other factors that come into play depending on the blend of local conditions of sun, wind, rain, clouds, etc.

When the sun is strong and temperatures are high, wind tends to be weak.

Conversely, when wind is strong and skies are cloudy with rain and moisture, sunlight is minimal.

Therefore, a combination of wind and solar will likely increase energy production during any cycle.

Solar power is low in density, requiring large surface areas. Installations require site improvements and lengthy transmission lines. Solar systems are not portable and in order to maximize energy capture throughout the day and over the seasons, must incorporate azimuth tracking at additional expense. If not, then seasonal performance will vary, and customer needs may be curtailed.

Ideal from homes, commercial establishments, bird friendly

Ideal for Commercial buildings and Institutions

Small wind electric systems can Lower your electricity bills by 50%–90%,Help you avoid the high costs of having utility power lines extended to a remote location,Help uninterruptible power supplies ride through extended utility outages. Small wind electric systems can also be used for a variety of other applications, including water pumping on farms etc.

Our Wind Turbines wind turbines  are Vertical -axis, Flow wind machines that have 5 blades. These blades are made of a composite material which is weather proof and durable . The minimum wind speed required can be as low as 1.5 meters per second which makes them ideal and suitable to be used even in the urban areas. We  make turbines ranging from 500 watts to 20 Kws . In addition to this we also manufacture custom capacities on demand .

How a Small Wind Electric System Works?

Wind turbines convert the kinetic energy in wind into clean electricity. When the wind spins the wind turbine's blades, a rotor captures the kinetic energy of the wind and converts it into rotary motion to drive the generator. Most turbines have automatic overspeed-governing systems to keep the rotor from spinning out of control in very high winds. These turbines can be run both as off grid ( Islanded) or grid tied ( Provided the state government's Discoms policies permit that , Please check with your state policies on renewable energy net metering) .

Because of the compactness these can be mounted on roof tops or from any other elevated position or hosted on poles .

The Operational Expenses Model

Solar & Power: Image


The BOOT model of build own operate and transfer

If the initial capital cost is an entry barrier HIMANG proposes the  BOOT model where the same benefits can still be enjoyed but as an operational expense instead, we call it the energy sale model .
Our On-site solar energy solutions are pay-as-you-go model, where corporates pay for solar electricity at a rate lower than grid tariffs – in fact, up to 20-40% cheaper.
As there is zero investment, there is no capex and none of the associated performance risks either. This translates into considerable savings for companies, which are also risk-free. Our team will take care of the entire operation and maintenance for the 25-year life of the system. All you need to do is sign a Power Purchase Agreement, and sit back and enjoy the benefits.
We also have the capital equipment lease model in which the clients pays a monthly rent depending on the size of the plant and enjoys the power generated . If this interests you please do write back to us at to get further information , we would be glad to serve you.
