Solar

Rooftop Domestic: On-Grid

An on-grid solar power system provides your home with the electricity required during sunshine hours. As it is connected to the grid, you can draw power from the grid when electricity generation is low — primarily during the night and on cold and cloudy days

Solar

Rooftop Domestic: Off-grid

An Off-grid solar power system provides your home with the electricity required during sunshine hours. As it is not connected to the grid, you can draw power from the battery storage when electricity generation is low — primarily during the night and on cold and cloudy days

Rooftop C&I

The C&I customer segment in India has realised the potential benefits of solar and this awareness has improved the adoption of solar in the sector.
One of the major incentives of choosing solar is the cost benefit due to the substantial reduction in electricity bills. Industries can reduce their dependence on grid power and choose to power their facilities with solar instead. With ‘net-metering’, excess power generated by the solar system can be exported to the grid and the customer can get credits for the units supplied to the grid. This further cuts down the electricity bills. As the life of the solar system is for 25 years, customers are also protected from any future rises in grid tariff.
C&I customers can also take advantage of tax benefits provided by the government. Under Section-32 of the Income Tax act, the consumer can benefit from accelerated depreciation of 40% every year until the asset is fully depreciated.

EPC

In the solar industry, EPC stands for Engineering, Procurement, and Construction. It is used to address the photovoltaic companies that provide end-to-end solar services from designing to procuring the components and finally installing the project. Some Solar EPC companies even take up maintenance work during the duration of the solar power plant

Operations & Maintenance

General checks

As a solar plant is installed, engineers at CleanMax prepare a schedule for preventive maintenance. This includes, but is not limited to, adjustments, cleaning, lubrication, repairs, replacements, and the extension of equipment life. At least twice a year, O&M personnel conduct a general inspection of the installation-site.

01Ensure roof drainage is adequate, roof drains are not clogged and confirm that there are no signs of water pooling near the array
02Ensure roof penetrations (if any) are watertight
03Check for ground erosion near the footings of a ground mount system
04Confirm electrical enclosures are only accessible to authorised personnel
05Check for corrosion on the outside of enclosures and the racking system
06Check for cleanliness throughout the site to ensure that there is no debris in the inverter pad area or elsewhere
07Check for loose hanging wires in the array
08Check for signs of animal infestation under the array

Operations & Maintenance

Specific checks

Modules

Modules need the most preventive maintenance. Cleaning is carried out in a fortnightly basis. Cleaning of modules is done keeping TDS(Total Dissolved Solids), which needs to be below 250 parts per million (PPM), in mind. Good quality brushes without hard bristles need to be used for cleaning to prevent damaging the glass surface of modules. Technicians are presently trying to develop automated cleaning systems. Post wash, the modules are wiped dry to ensure no stains remain.

Inverter

Most German-make inverter manufacturers recommend servicing it on a quarterly basis. However, CleanMax carries out servicing on a monthly basis as there is a lot more dust in India compared to other countries. The ventilation is provided via a filter, and this filter needs to be frequently cleaned. Therefore, usage of high-quality filters is advantageous. As part of preventive activities, our engineers check the voltage of the string inverter and record it in the periodic log book. This gives an understanding of voltage fluctuations if any.

MC4 Cabling Connector

Under preventive measures, we ensure that there is no gap between the male and female connector pipes. Any gap, irrespective of the size, could cause a fire and damage the modules. Separately, off-takers can install a “check” meter of equal or higher accuracy with reference to the main meter to cross-check the production level on a monthly basis. All readings have to be, more or less equal, with a 2-3% correction allowance.

Transformer

For transformers at the site with installed capacity in megawatts, parameters such as the operating temperature, OTI (oil temperature), WTI (winding temperature), and oil level are monitored daily. If there is any internal disturbance in the transformer, it reflects in these parameters which are monitored at least three times in a day (at 11 AM, 02 PM and 04 PM as solar power is generated at its peak during these slots). The transformer has to be cleaned thoroughly once in six months. CleanMax conducts IR test and cable yearly to check the transformer performance.

Protection from external elements

To ensure that the plant is working smoothly (i.e. without any shutdown), the same has to be sealed properly. Else, rats and other rodents can enter, and get electrocuted. This, in turn, can cause a short circuit, and affect the entire plant. Many people are not aware that even high-pressure water can damage the modules. If the water stream is too strong, our team will place the outlet at a farther distance.

Remote monitoring

A solar power plant constantly needs to be monitored to detect breakdowns and optimise its operation. The same function could be performed either on-site or remotely wherein we retrieve all the data either from the inverter or from communicating equipment (probes, meters etc.).

Solar

Warranty settlement

The product warranty replaces your solar panels for free if they malfunction due to material or workmanship defects. The coverage period varies depending on the brand and specific product, but the solar industry standard for performance warranty guarantees a maximum level of degradation – typically between .25% and .75% – per year so that in 25 years the panel will still have 80-90% of the power output it did in its first year. Performance warranties are important for sizing solar systems to maintain 100% offset for 25 years, if there is any difference in the performance, we will help you to get the warranty claim from the Manufacturer/OEM

Solar

Solar Water Pumps

The system operates on power generated using solar PV (photovoltaic) system. The photovoltaic array converts the solar energy into electricity, which is used for running the motor pump set. The pumping system draws water from the open well, bore well, stream, pond, canal etc

BESS (Battery Energy Storage Systems)

Battery storage systems will play an increasingly pivotal role between green energy supplies and responding to electricity demands. Battery storage, or battery energy storage systems (BESS), are devices that enable energy from renewables, like solar and wind, to be stored and then released when the power is needed most.
