There is no such thing as free lunch but of course, there is free energy called solar energy. Solar energy denotes the energy obtained from the ray of the sun. The solar energy has been used for centuries in everyday work like cooking, heating and drying clothes. Current with the more exploitation of fossil fuels people are inclining back to the renewable sources of energy like solar, wind, water etc. The use of solar panels has nearly quadrupled in last four years. Some of the cities have already claimed to be running on hundred recent renewable resources. A simple household solar panel can reduce the carbon emissions by 100 tons during its lifetime as suggest by a research. Other than the pollution caused during the manufacturing of the solar panels, solar energy does not produce any sort of pollution. Undoubtedly, solar energy is the cleanest and cheapest form of energy available.
Solar panels and controllers
Solar energy has been passively used since the beginning of the life on earth. The active harnessing of solar energy started just two centuries ago in 1830 when Alexander Edmond Becquerel discovered photovoltaic effect. Photovoltaic effect simply means the excitation of electrons in atom due to the rays of the sun as a result of which current is produced. Solar panels consist of photovoltaic cells which produce electricity. Normally solar panels are of 250-500 watts. Solar panels are a one-time investment which gives benefit for the long term. Due to more demand, the solar panels are available at affordable prices now in the market.
Another important component required to convert the solar energy for household use is solar charge controller. Charge controller helps to regulate and limit the current flow into the battery from solar panels and from the battery to household appliances and circuits. A good solar charge controller provides long life to the battery and inverter by protecting it from overcharging and overvoltage. Without charge controller, the solar energy can only be used when the sun is shining. Pulse Width Modulation (PWM) and Maximum Power Point Transfer (MPPT) are the two types of charge controllers available in the market. MPPT charge controllers are more efficient than PWM controllers.
Recommended Charge Controller: 40A MPPT Charge Controller 48V/36V/24V/12V Solar Battery Regulator Max 130V DC Input
This MPPT charge controller is ideal for any type of installation from large scale to small scale. This solar charge controller uses MPPT technology with 99% efficiency and can be used for wide range of DC voltage from 12 V to 48V with 130V output AC. This controller can handle load up to 40A which is enough for household use. This charge controller can also be monitored remotely by connecting it to the router. With the lit LCD screen, ever information regarding the voltage level, battery percentage, and load usage can be viewed easily. This controller is available on Banggoog.com at a very reasonable price.
To efficiently utilize the solar energy, a good MPPT charge controller is required and the above-mentioned product provides every feature required for efficient utilization. So it is always best to prepare for the upcoming fuel crisis with the solar panels and charge controllers and contribute towards the green energy and environment.
