A meticulously designed Photo Voltaic system entails a lot of details. As it is said “the devil is in details”. For example even the in correct wire size of the system affect the performance. You lose energy in the wires which translate to decreased kWh unites (loses of the system increased). Safety also plays a major role handling high DC voltages and power, power conditioning units require expertise and often counter intuitive experience.
Blatant exposure to sun in the Indian subcontinent (where 300+ sunny days & summer temperature of over 41*C) creates difficult engineering problems.
Continues exposure is bound to degrade the quality of metal and plastics. What it implies is at the electrical connection which ranges from tiny wire connects to general signal phase or three phase circuit breakers (DPST- dual pole signal throw switch) must be carried out with apprehension and utmost care.
Weather has a habit of being unpredictable, India has a very varied weather conditions and that can sometimes work against your installation. Your system may start to show corrosion or safety hazards and may even become dangerous.
Bottom line is choosing an overall good contractor who understands all these technical ins and outs is immensely significant to the success of your solar rooftop PV system installation. Or simply connect Shaktisteller Energy Solutions. A good contractor doesn’t make wild claims like offering same output at half the price or roof area other than the standard (you can check the standards at MNRE website) Or, providing energy saving devices connected to your switch boards so that you use half the power from the grid to achieve the same result that you would with an on grid system.
Albeit, the solar power industry is changing daily and so is the technology.
It almost goes without saying that experience is highly important in any type of business. Nobody wants to buy from the company who hasn't had a wealth of experience. The solar company you choose should be able to demonstrate that they have experience installing systems similar to the one they propose to sell to you.
