Types of solar panels and Inverters You should know about.

Solar panels, also known as photovoltaic cells, are capable of absorbing light energy through semiconductor materials and converting it directly into electricity by the photovoltaic effect. Photo voltaic cells were discovered in the 1960s. Solar panels made up of PV cell modules made it to the rooftop first time in the 1980s. Photo voltaic effects basically ensure that the semiconductor material in the cell absorbs the photons carrying the solar radiation and converts them into electrons. There are different types of solar panels available on market. Initially, these two types were majorly used in the market; mono crystalline and polycrystalline.

Mono crystalline

Mono crystalline panels have an efficiency rate of 20%. It is optimized for commercial use. These panels have a high life-time value.

Poly crystalline

Polycrystalline panels have a 15% efficiency rate. Although these panels have a lower price compared to monocrystalline solar panels but there are a number of disadvantages; these are sensitive to high temperatures

These panels have a lower life span and considerably less space efficiency.
These days, the solar panels which are most frequently used are mono perc panels. From traditional poly panels to mono & bifacial modules, we are continuously evolving.
Mono-perc is an un-conventional version of mono-crystalline panels that are considered to have higher efficiency even in low-light condition. PERC stands for Passivated Emitter & Rear Cell. It is a modern technology that is designed to increase the efficiency of standard solar modules. This is done by adding a passivated layer in the rear of the cell. In Mono-perc modules, the same passivated layer is added in the back (rear) side of the solar cells. This is designed this way so that any light which is absorbed and passes through the cell is not wasted and used again with help of the rear cells.

Solar Inverter is basically the pivotal unit of whole solar energy unit. It converts the DC energy coming in from solar panels and converts it into AC power to be utilized at home or workplace. The appliances in the house run on AC, not DC, this inverter is required to transform the D output of solar panels to alternating current which helps run all the appliances. Inverters ranging from 10kW-30kW are generally used in households (small residences) and inverters ranging from 20kW up to 100kW are used for commercial uses. Most common inverters used for household and commercial use are Hybrid inverters. Batteries are

connected with the Hybrid inverters. It engages with the connected batteries through ‘DC coupling’ (when both the solar and batteries use one inverter and the DC from the solar panels charges the batteries via a DC charger) and its electronics organize the charging and discharging of the battery.

 A few major high-end companies of solar inverters are listed below:

  • Sungrow
  • Huawei
  • Solis
  • Growwat
  • Knox
  • SMA
  • Inverex
  • Solarmax
  • Voltronic
  • Telsa
