    Frequently Asked Questions about Solar Energy
  • Q. How does solar power work?

    The two most common types of solar energy technology are photovoltaic (PV) cells and solar thermal collectors.  PV cells contain a semiconductor material (typically silicon-based) which converts sunlight into direct-current (DC) electricity.  An on-site inverter converts the DC power to 230-volt AC power, which can then be connected to a home or building’s power supply.  Solar thermal collectors absorb the sun’s thermal energy and use it to heat water or other fluids, which can be used for hot water or circulated through a home or building for space heating.

    Q. What are the components of a Solar power plant?

    Generally, a Solar power plant consists of the following components:

    • Solar Panels: For converting energy in Sun rays into Electrical energy (DC power)
    • Solar inverter: For converting DC electricity into usable AC power (230V-50Hz)
    • Batteries: To store electrical energy for use when Sun is not shining
    • Mounting Structure: Holds the PV panels at particular inclination and direction for maximum efficiency
    • Balance of System (BoS): Includes junction boxes, MCB, connectors, lightening protection etc.

    Q. How can Solar energy be used optimally?

    Solar day time usage pattern

    As per current technology scenario, Solar energy can be optimally utilized during the day time. As seen in the graph above, for typical day time load (e.g. offices, institutions, workshops, etc.) power consumption peaks around the time when Sun’s energy is received the maximum (yellow area in graph). This scenario allows us to consume the Solar energy as it gets generated. So, the requirement to store energy in batteries gets reduced and results in substantial reduction in initial and running cost of solar power system.    

    Q.How much space do I need for a solar photovoltaic system?

    In bright sunlight, a square foot of a conventional photovoltaic panel will yield 10 watts of power. That's a helpful rule of thumb for calculating a rough estimate of how much area you might need. For example, a 1000 watt system may need 100 – 130 square feet of area, depending on the type of PV module used.

    Q. Can I see Solar product demo before installing Systellar products?

    We invite everyone to see live demo of our Solar products at Systellar Solar Shoppe at Meerut. This is the 1st Showroom in North India running 100% on Solar Power. All loads inside the showroom including 1.8T Air-conditioner, lights, fans run exclusively using solar energy produced by 3.75 kW Solar power plant. At Systellar Solar Shoppe, we also provide free consultancy regarding proper usage and installation of solar equipments.  We have live demo for the following:

    • Solar power plant
    • Solar water heating system
    • Inverter battery charging system using solar power
    • Solar street/campus lights
    • Solar Water pump solution

    Q. What incentives are available?

    Currently Central Govt. through MNRE (Ministry of New and Renewable Energy) provides 30% subsidy on Solar systems including Solar power plants, Solar water heaters, Solar street lights, etc. This subsidy is applicable on complete systems and not on sub-parts of a Solar system. Systellar Innovations has the necessary tie-ups to provide you complete benefit of Govt. subsidy schemes.

    Q. What are the environmental benefits?

    Solar energy creates electricity and heat and avoids pollution from conventional coal plants and nuclear plants.  Using national average emission factors, every megawatt-hour of electricity generated through a solar PV panel avoids more than 1,300 lbs of carbon dioxide (CO2), more than 5 lbs of sulfur dioxide (SO2), and almost 2 lbs of nitrogen oxide (NOx), and it also avoids producing radioactive nuclear wastes. Solar energy production is highest on sunny days when air conditioners are running and electricity demand peaks. 

    Q. What is the scope of Solar power in India

    India is densely populated and has high solar insolation, an ideal combination for using solar power in India. Due to its geo-physical location, India receives solar energy equivalent to nearly 5,000 trillion KWh/ year, which is far more than the total energy consumption of the country today. West UP region on an average has 300 to 330 sunny days in an year and is perfectly suited for Solar power generation.

    Q. Does solar power make sense for me?

    There are a couple of factors that go into whether or not solar is a good fit.

    • Do you have daytime or night time load?
    • Does your roof get clear sunshine throughout the daytime?
    • Does your roof receive shadows from trees/building during daytime?
    • Do you have budget for solar solution?
