    Under PM Surya Ghar, the govt gives upto Rs 78.000 for a 3KW rooftop solar system and upto Rs 30,000 per Kw for systems below 3 KW. For those going above 3 Kw there are no additional subsidies as the benefits are capped upto 3 KW. In addition to the central subsdies, you get additional subsidies from states too. Check out your additional state subsidies from your local discom or energy department.

    Precautions for inverter installation and maintenance:

    1. Before installation, you should first check whether the inverter is damaged during transportation.
    2. When selecting the installation site, it should be ensured that there is no interference from any other power electronic equipment in the surrounding area.
    3. Before making electrical connections, be sure to cover or disconnect the AC and DC side isolator switch with opaque materials. When exposed to sunlight, the PV array will generate dangerous voltages.
    4. All installation operations must be performed by professional technicians only.
    5. The cables used in the photovoltaic system power generation system must be firmly connected, with good insulation and appropriate specifications.
    6. All electrical installations must meet local and national electrical standards.
    7. The inverter can be connected to the grid only after obtaining the permission of the local power department and all electrical connections are completed by professional technicians.
    8. Before performing any maintenance work, first disconnect the electrical connection between the inverter and the grid, and then disconnect the DC side electrical connection.
    9. Wait at least 5 minutes until the internal components are discharged before performing maintenance work.
    10. Any fault that affects the safety performance of the inverter must be eliminated immediately before the inverter can be turned on again.
    11. Avoid unnecessary board contact.
    12. Observe the static protection code and wear an anti-static wrist strap.
    13. Pay attention to and follow the warning signs on the product.
    14. Visually inspect the equipment for damage or other dangerous conditions before operation.
    15. Pay attention to the hot surface of the inverter. For example, a heat sink of a power semiconductor or the like maintains a relatively high temperature for a period of time after the inverter is powered off.
    16. Use proper safety equipments while working on installation and maintenance. Operations should be done by an experienced technician only.

    Inverter installation location requirements

    1. Do not install the inverter in direct sunlight. Failure to do so may result in additional internal temperature of the inverter, which will derate the inverter to protect internal components. Even the temperature is too high, causing the inverter temperature to malfunction.
    2. The installation site should be strong enough to support the weight of the inverter for a long time.
    3. The ambient temperature of the selected installation site is -25 °C ~ 50 °C, and the installation environment is clean.
    4. The ambient humidity of the selected installation site is not more than 95%, and there is no condensation.
    5. There should be enough clearance in front of the inverter to make it easy to observe the data and repair.
    6. Try to install it away from the living of the residents, and some noise will be generated during the operation.
    7, the installation place to ensure that it will not shake.

    ALMM stands for the Approved List of Module Manufacturers. It is a list released by India’s Ministry of New And Renewable Energy (MNRE), and lists all the manufacturers whose modules are approved for use in solar projects in India.

    Following a recent notification on March 27, the MNRE has made it clear that only ALMM approved modules can be used in all government backed projects, and even projects in Open Access and Rooftop solar. That means you could potentially use foreign modules (after paying a 40% customs/import duty), only in off grid solar projects that are not subsidised in any way, if at all.

    For more coverage of ALMM and manufacturers there, do refer to SaurEnergy.com.

    Besides the PM Surya Ghar guidelines, the actual installation takes place in compliance with the state regulations on rooftop solar. For example it is the state regulation which talks about the state’s financial support given to customers besides the central subsidies. State rules also talk about the time period for completing Technical Feasibility Report, commissioning of rooftop solar project and other persmissions.

    Installing a solar inverter with a higher capacity offers several advantages. Firstly, it provides flexibility to increase the DC capacity of the solar array in the future without needing to replace the inverter. This reduces the overall stress on the inverter components and lowers the probability of failures over time.

    However, it’s important to note that installing a significantly higher capacity inverter than necessary is not always required. Most inverters are designed to operate efficiently even in higher ambient temperatures. However AC to DC ratio, typically ranging from 1:1 to 1:1.2, can be sufficient to ensure optimal performance and reliability without the need for excessive overcapacity in the inverter.

    Usually in a residential rooftop project, a 3 Kw rooftop solar can ideally generate upto 10-12 units per day. The daily generations are usually dependent on the local weather. Usually when there is good sunlight throughout the day, you can get the best generation (if your solar panels are clean). During clouds, rains, the generations reduces. So a system which can generate around 12 Kw per day can also generate 5 kw or 7 Kw during clouds/rains. The generation also varies season to season, depending on the quality of sunlight and availaility of sunlight.
