The global formula to estimate the electricity generated in output of a photovoltaic system used in solar power plant for generating solar energy for home/industrial/commercial roof top or ground mounted is :
E = A * r * H * PR
Where E = Energy (kWh) ,A = Total solar panel Area (m) ,r = solar panel yield (%) ,H = Annual average solar radiation on tilted panels (shadings not included) ,PR = Performance ratio, coefficient for losses (range between 0.5 and 0.9, default value = 0.75) , r is the yield of the solar panel given by the ratio : electrical power (in kWp) of one solar panel divided by the area of one panel

Example : the solar panel yield of a PV module of 250 Wp with an area of 1.6 m is 15.6%
Be aware that this nominal ratio is given for standard test conditions (STC) : radiation=1000 W/m, cell temperature=25 C, Wind speed=1 m/s, AM=1.5. The unit of the nominal power of the photovoltaic panel in these conditions is called "Watt-peak" (Wp or kWp=1000 Wp or MWp=1000000 Wp).
H =solar radiation data
You have to find the global annual irradiation incident on your PV panels with your

After the solar panels used in solar power plant for generating solar energy for home/industrial/commercial roof top or ground mounted, are installed , the dirt starts to built up over the panels and can substantially affect system performance. It is required to be cleaned up from time to time regularly to avoid losses of solar energy. But while cleaning can enhance the system performance but wrong cleaning processes of materials used can lead to bad performance of the system. Therefore one needs to be careful in selecting the right materials , tools and processes for cleaning the solar power system. While the right materials , tools and processes are necessary , it is equally important to have trained manpower to do the job.

Solar Panels : A lot of duplicate panels , used in solar power plant for generating solar energy for home/industrial/commercial roof top or ground mounted ,are available in the market and cheaper solutions use the same. In absence of customer knowledge on the subject they are taken for a ride . To avoid malpractice , customers should insist on seeing the panel sl no via a RFID reader , which we are sure the vendor should have . And if some vendor says that he does not have a RFID reader then please avoid getting systems installed by such vendors.

Designing layout for a solar installation is an expert job and needs to be done with utmost care. There are two important considerations while designing solar panels installation used in solar power plant for generating solar energy for home/industrial/commercial roof top or ground mounted, one is inclination of the panels and another is direction. The angle of tilt should be latitude of the place wherever the installation is being done to optimize the radiation of solar and direction should be true south.

Getting a solar system , for generating solar energy for home/industrial/commercial roof top or ground mounted, is only a small part of the effort, the key is in maintaining the performance of the solar system month on month basis. According to estimates, regular maintenance can increase the performance by 30% of the solar system installed over your roof or on the ground.

With the advancement in technology, the sizes of the solar panels are reducing to provide the same potential of electricity. Right now the panels available in delhi / NCR can provide up to 340 Watts of power from a single panel. It means three would be a requirement of at least 3 panels if one wishes to generate 1 KW of solar power.
The panel sizes generally available in the markets will include panels from 250 watts onwards. Commonly available will include panel sizes of 315 watts, 330 watts and so on.
The panel size of a 315 watt panel will be around 2.0 meter X 1.0 meter based on the specifications provided by key suppliers. Typical specs of a panel are as follows -

There are a number of suppliers to buy solar PV panels used in solar power plant for generating solar energy for home/industrial/commercial roof top or ground mounted. These solar PV panel suppliers are divided into various tiers out of which Tier 1 suppliers are considered best. The division of solar PV panel suppliers into tiers is done mostly based on the financial strength of these companies while few technical parameters are also considered in this review.

Normally structures are made of MS and then galvanized with 80 microns of Zinc coating. The height of solar panels after mounting on such structures from roof surface remains 300 mm to 750 mm only. Sufficient only to allow cleaning roof below the panels from time to time. But it is possible to increase the height of structures to 2-3 mts also , giving enough room below the panels to create a workable space or do roof gardening below the panels, while the panels produce solar energy for your home/ industry. In some cases industries have used that space for

An Array Junction Box, AJB, is used to connect the photovoltaic strings in parallel. The combined DC power is fed to the photovoltaic inverter. It includes photovoltaic string protection, overvoltage protection and a DC output switch isolator. The AJB can be customized for different configurations, based on the number of strings of solar panel modules used in the layout. AJB have the following component

Solar photovoltaic (PV)cells / modules generate electricity from sunlight, which can be fed into the mains electricity supply of a home/industry/building or sold to the public distribution company connected to the grid. This will Reduce the need for generation through fossil fuel technology. More and more solar energy systems on roof top will help create jobs, enabling home/industry/building to save money, and cut greenhouse emissions/ pollution.

A string monitors system is the advanced version of AJB. AJB with string monitor unit is called SMB (string monitoring box). A string monitor system has the main objective to monitor the individual string current & common bus voltage on real time basis. It also has the temperature measurement facility for the keeping a check on the temperature inside the box. The string current, voltage & temperature are measured & communicated through a RS-485/Zigbee over Modbus protocol. It should be compatible with SCADA system. It helps in easy detection & identification of fault in any string. After getting the location
