1. Load assessment

• What is the load ?  What is the backup required? कितने किलो का लोड है?  और कितनी देर चलाना है?

We need to calculate the units (kWh) required. Since most the customer not sure with there backup requirement they are confused and not properly sure about the investment and requirements. Lets be specific with battery backup and prices in the 1st meetings. 

• Need to check  load either inductive or Resistive. (आप का लोड कितना एम्पीयर करंट लेता है ?)

We should run the complete load and check the current position. We need to see phase balanced or not does our selected inverter support it or not. If current crossing the limits of said inverters range in terms of current carrying capacity. you need to increase the inverter ratings. Make sure to customer that it is just increment of the inverter rating nothing to do with battery backup. 

2. Shadow free Space available at the site.  

• Initially we need to understand the shadow free space. As per customer demand  need to calculate the total possible irrigation  of the solar power plant accordingly we can calculate possible storage and inverter battery sizing. 

• Figurate the best available space for solar modules in terms of direction and shadow free area. 

• Inverter(PCU) & should have minimum distance. Dust free and proper ventilation specially annullable or not. We need to demand the special room space available there. 

3. Selection of  products 

After seeing the plant feasibility we need to finalize the product size and make accusing to the customer. 

• Inverter : Initially we need to conform the  inverter make and rating as per unit demand we can conform the  inverter voltage and kVA rating. We can take the rating with voltage. Once the voltage gets finalizes we can select the battery rating and solar panel ratings. 

• Battery : To decide the battery rating we need to finalize the make and rating . 

The Battery (Ah) * Depth of discharge (DOD)  * Inverter Voltage Rating (V) * K  Factor = W*H*days 

Battery (ah) = W*H*Days/ Depth of discharge (DOD)  * Inverter Voltage Rating (V) * K Factor

Lets take Example : 

if  we required  4 units

inverter voltage = 48V

DOD= 60%

Inverter effiency : 85%

Kfactor = 0.987

Ah = 4000/.6*.85*48*.987= 165ah 

So the required battery Ah =12V 165Ah

4. After conformation of the products and sizing need to confirm the

1. Site Assessment:

• Evaluate the location for solar plant installation, considering factors such as solar resource availability, shading, structural integrity, and electrical infrastructure.

• Determine the suitability of the site by analyzing solar irradiance data, local weather patterns, and any potential obstructions that may reduce solar energy production.

2. Permits and Regulations:

• Research and comply with local regulations, building codes, and permit requirements for solar installations.

• Obtain the necessary permits and approvals from local authorities before commencing any construction or electrical work.

3. System Design:

• Engage a qualified solar engineer or consultant to design the system, considering factors like energy requirements, available space, solar panel orientation, and inverter capacity.

• Determine the type of solar panels (monocrystalline, polycrystalline, thin-film) and mounting systems suitable for the specific location and project goals.

• Design an appropriate layout, including the arrangement of solar panels, inverters, wiring, and other electrical components.

4. Safety Considerations:

• Ensure the safety of personnel involved in the installation by providing proper training and personal protective equipment (PPE).

• Follow electrical safety guidelines and best practices to minimize the risk of electric shocks and fires.

• Implement appropriate measures to prevent falls, such as using safety harnesses and guardrails when working at heights.

5. Installation Process:

• Engage a professional solar installation team or qualified contractors with experience in solar projects.

• Install the mounting structures securely and ensure they are properly anchored to withstand environmental conditions.

• Install solar panels according to manufacturer specifications, taking care to connect and wire them correctly.

• Install inverters, electrical connections, and protective devices (e.g., fuses, surge protectors) in accordance with electrical codes and safety standards.

6. Testing and Commissioning:

• Conduct thorough testing of the entire solar system, including electrical connections, inverters, and monitoring equipment.

• Verify the performance of the system by measuring energy production, voltage levels, and other relevant parameters.

• Ensure all safety features are functioning correctly and conduct a comprehensive inspection of the installation before commissioning.

7. Monitoring and Maintenance:

• Implement a system for ongoing monitoring of the solar plant's performance to detect any issues or malfunctions promptly.

• Develop a maintenance plan that includes regular cleaning of solar panels, inspection of electrical components, and addressing any necessary repairs or replacements.

• Keep detailed records of maintenance activities, inspections, and system performance for future reference.

Remember that these guidelines provide a general overview, and the specific requirements for solar plant installation may vary depending on local regulations, project size, and other factors. It's crucial to consult with professionals and adhere to local guidelines throughout the installation process to ensure a safe and successful project.
