How long does it take to install a Solar Power Plant?

Time taken for design, installation and commissioning of a Solar power plant varies with the size and place of installation. We generally commit and deliver within 4 to 6 weeks. An exact time estimation varies on the complexity of the roof and would be clearly stated in our techno-commercial quote to the client.

How will the new Solar power plant integrate with the existing power distribution set-up?

A Power conditioning unit (PCU) is the heart of our Solar power plant. It has extremely advanced capabilities to act as the heart of the power distribution network or set-up when combined with a Solar power plant. The PCU will put Solar power as the first preference for consumption followed by Grid power and then a Diesel generator if installed. The preferential order ensures that every unit of clean power produced by the Solar power plant gets consumed before switching to other means of dirty power.

What are the components of a Solar power plant?
    A Solar power plant will have following components

  • Solar panel array – These are the crystalline silicon cell induced panels that generate DC power when sunlight falls on it
  • Solar power condition unit – This is the heart of a solar power plant. It converts the DC produced by the panels for AC supply. Moreover, it does various other functions of harmonics correction, power factor improvement and power flow management
  • Battery bank – A solar plant generates electricity during day-time but load components need to be powered during night time as well. A solar panel array is designed to produce enough power for both the times. The power thus produced during the day-time but not consumed during this period gets stored in the battery bank to power the load during the No-sunlight time.
How is a Solar photo-voltaic power plant different from a Solar water heating system?

A Solar PV or Photo-voltaic power plant works on the principle of Photoelectric effect as discovered by Albert Einstein (for which he got his Nobel Prize in 1922). The Solar PV panel used in such a plant converts the energy stored in the photons in the Sunlight to electricity. This electricity generated in DC form is conditioned for home, commercial or industrial use accordingly.
Solar water heating system on the other hand simply uses the heat component of the Sunlight in an efficient and clever manner. The heat energy thus trapped is used to heat water to some degrees or even to steam for further use in various different forms.

What are the types of Solar power plants that one can install?
    A solar power plant can be of 3 different types.

  • Grid Tie system – This system gets integrated with the State grid supply and transmits back any power that the plant has produced and the load doesn’t consume. The system would trip when there is no Grid supply. Evidently, this system won’t have a battery bank and is not a viable option in regions with regular power cuts
  • Off-grid system – This is system has a battery bank and stores energy for later usage. Also the system continues to function, even when there is no grid supply. This type of system is more suitable for Indian power conditions considering the frequent power outages but operates at lower efficiency as compared to a Grid-tie system with the inclusion of batteries as part of the system
  • Hybrid system – This is a combination of both. The entire power requirement during the daytime gets routed directly to the load as in a grid-tie system. Night time load requirement gets routed through the batteries as in an Off-grid system. Power cuts won’t put off the system and the power management system is capable of putting extra electricity generated if the client wish to do so (only if the state has a net metering regime in place). Needless to say, a hybrid power plant require clever designing and careful planning during installation.
How much electricity does a Solar power plant generate?

Every one kWp of Solar power plant capacity generate 4 to 7 kWhs (commercial electricity units). Subsequent addition of kWp capacity will generate more units of electricity proportionally.
The exact amount of electricity will depend on the Solar radiation received at your location. We will be providing you this information in our DPR (Detailed Project Report) that will handed over to you along with our techno-commercial quotation to you.

Can this Power generation capacity of Solar power plant be increased?

Power generation capacity can be increased by installing a Sun-tracking Solar panel array. The Sun-tracking arrangement ensures that the Solar panel array stay perpendicularly incident to the sunlight at all times. The trouble however is the cost. At current Indian market rates, additional power generated by using a sun-tracking arrangement cannot offset the additional cost incurred for having this system installed as part of your Solar power plant.

Can LED installation improve the cost-effectiveness of a Solar power plant?

LED fixtures and lighting solutions not only make your Solar power plant more cost effective but also more green. LED lights consume much less power (measured in kWh) for the same amount of light output (lumens). The Chart below will give you a precise measure of this fact.

 

What’s important to note here is that LEDs offer you much more light output in lumens for every watt of electricity that it consumes when compared to a conventional incandescent light. In comparison to CFLs , even though a significant energy saving can only made of higher lumen ratings, LEDs still score over CFLs in a big time when it comes to the life of these fixtures. We advise being prudent with the quality of LED lights that you buy for realising this longer life span.

Will the Solar power plant generate same amount of power on a daily basis throughout the year?

No. Every place has a different pattern of Solar radiation. We as a part of our techno-commercial quote provide our client with a DPR (Detailed Project Report), which details the amount of electricity that the plant will generate daily on a month by month basis. We use MNRE (Ministry of New and Renewable) radiation data of Solar Photo-voltaic to generate these figures.
Please Note: There are various types and sources for Solar radiation available. Each of these has a purpose and it needs an expert to decide the right kind of information to be used. We share this relevant information once again as part of our DPR (Detailed Project Report)

What is the area required to install Solar panel array?

Every 1 kWp Solar array would require 7 to 9 m2 of unshaded area for installation depending on the location and incident radiation.

What’s the life of a Solar panel array?

A good solar panel array will be in service for 25 years from the date of power plant commission.

What is the maintenance required for Solar panel array?

All that needs to be done as part of a maintenance routine for Solar panel array is simple cleaning. The required frequency for this cleaning is once in two weeks to twice a week depending on how dusty the place or weather is. Compare that with the expensive servicing & oil change routine required for Diesel generators and you know why the running cost of a Solar is almost close to zero.

What are the safety features needed or included as part of a Solar panel array?

A Solar panel array is made safe from any lighting related risks by having appropriate lighting conductors as part of the Solar power plant components provided by us. The toughened glass on top of every Solar panel is capable of withstanding rain, snow and even hail to the size of 1 inch hitting the panel at a speed of 120 miles per hour.

What is net metering? Is there any other means to earn money from Solar power plant other than electricity bill / diesel cost saving?

Net metering is a unique concept much prevalent in the developed world. It lets the solar power plant owner sell back the power to the state grid at a rate which may not be the same or may be even higher than the rate at which he/she buys it from the grid and thus facilitating an additional revenue stream for the solar power plant owner.
Currently, this concept has being introduced in six places in India on a trial basis, namely – Gandhinagar (Gujarat), Pondicherry, tried out on a pilot basis. Obsolete components and instability of the power grids in India restricts fast adoption of this concept in the country.

Do Solar power plants come with a fixed per kWp costing?

One should be beware of firms or individuals quoting a fixed per kWp costing for a solar power plant. A good cost effective system needs to be customized according to the user’s load and usage pattern and this customisation drives the cost of the system upwards or downwards.
