Sunlight (light, not heat) on photovoltaic modules produces direct current (DC) electricity which is converted to alternating current (AC) by a device called an inverter, which is then wired into your main service panel where it feeds your internal power grid.
Solar modules (panels) and inverters are the main components of a solar power system and they constitute 70% of project cost.
1 kWp solar system requires approximately 10 sq. m (or 100 sq. ft) of shadow free area. Therefore, one 1 MWp (1000 kWp) solar system would require 10,000 sq. m / 1,00,000 sq. ft / 3 acres of shadow free area.
1 MWp (1000 kWp) solar system would cost around 6.5 crores, including all components, installation and comissioning, delivery and taxes
1 MWp (1000 kWp) solar system would require 3-6 months time for installation and commissioning, and typically only 30-45 days of actual work at site.
Yes, wind load is considered. The wind load will depend upon the exact location. The installer should consider IS standards for the specific location. But solar power plants can be designed for any wind load.
Solar photovoltaic panels have no moving parts, and therefore require little maintenance, which will include module cleaning with water every 2-4 weeks and preventive electrical maintainance every 3 months.
A 1 MW plant will generate around 15 lac units in the first year. The exact power generated will be subject to location of the solar power plant
Yes, the power produced will degrade at 0.5 -0.8 % each year. In the 25th year the solar system will still produce 80-90% of the energy produced in the 1st year.
The solar panels have a warranty for a period of 25 years, however the projected life is longer
The evacuation of solar power happens at the LT room, in most cases at 415 V.
Metal Rooftop solar requires 20% lower area than RCC roof top solar or ground mount systems. Rooftop solar helps to reduce room temperature by around 2 degree Celsius. Otherwise both system are equivalent.
The cost of both systems is approxiately the same on a per Wp basis.
Both the systems will need a period of 3-6 months for installation and commissioning.
Solar panels will be mounted on high-quality aluminium structures, which will be fixed to the roof sheets.
Yes. If the roof sheets belong to the standing seam segment, then solar panels can be installed without penentrating the roof. If not then penetration is necessary, although precautions are taken to prevent leakage. Installation on RCC roofs does not require any penetration.
For installations greater than 1 MW in size, centeral inverters will typically be used and these will be set up in a separate room, called the control room. For smaller installations string inverters will be used and these will be erected on the roof or in the factory floor.
It will not, as you aren’t tampering with the roof. Just as you use screws to fix the roof sheets, we use screws to fix the modules.
Nope. As the cost of others components such as aluminium structures, copper wires are steadily rising and the total project cost is more or less stable.

Solar panel prices have declined signficantly in the past 5-10 years. This is from a combination of incremental technology improvements, the move to large-scale manufacturing in China, and an overcapacity in the market from 2007 to 2015. However, since mid-2015, module prices have stabilised and started to increase due to surging demand for solar worldwide.
