A blog about DIY solar and arduino projects
https://youtu.be/60zUwtgNvjo This post is specifically dealing with “Not Supported” that commonly displayed on the phone screen or slow charging due to shading effect when charging by a Solar Phone Charger. A good Solar Phone Charger has few rule of thumb designs : Ratio Solar Panel Capacity over phone charging power should 2 times or more. […]
https://youtu.be/OHt7pLP5blU Solar PV is very famous on phone charging application. Typical phone charging requires between 5W to 10W charging power. However, not all solar panels are made suitable for phone charging. Some may charge faster while some may charge slower with power limitation thus selection of solar panel is very important. Besides wattage rating, the […]
https://youtu.be/B54s2TAfsPY Solar direct DC application refers to Solar Panels directly connected to DC loads for operation without the need of battery bank as backup. This is the simplest and cheapest form of Solar PV System as it does not require expensive components such as battery and solar charge controller. It is also a long lasting […]
There are a lot of benefits from planting greenery in your garden. Besides having it as a hobby, it can enhance your patience and endurance. Planting trees not only can reduce carbon footprint, it also can provide shade and cooling to your house and surrounding. Fruit and vegetable plant may also provide you nutritious food […]
Current – Voltage (I – V) curve is a graphical representation of the Solar Panel operation summarizing the relationship between output voltage and current under various irradiation and temperature condition. By creating a I-V curve under known environmental condition, the output performance of the panel can be determined. A good quality Solar Panel will not […]
https://youtu.be/YBtfl6qtgT0 Energy Meter is a very useful device that displays important electrical parameters. A typical full specs of AC Energy Meter displays 6 important electrical parameters, which are AC RMS Voltage, AC RMS Current, RMS Power, Instantaneous Power, Power Factor and accumulate Energy consumption. There are 2 main sensors which measure instantaneous voltage and current values […]
Voltage Phase Rotation Meter is a device to detect and determine phase rotation sequence of voltage phases in 3-phase electrical system. Single Phase does not need voltage phase rotation meter as it consists only 1 live and 1 neutral. To differentiate live and neutral, you can use a test pen. When the tip of test […]
Energy Meter is a very useful device that displays important electrical parameters. There are 6 important electrical parameters in a Alternating Current (AC) Energy Meter, which are AC RMS Voltage, AC RMS Current, RMS Power, Instantaneous Power, Power Factor and accumulate Energy consumption. This device is used in all household loads measurement or AC energy […]
Energy Meter is a very useful device that displays important information of electrical parameters. There are 4 important electrical parameters in a Direct Current (DC) Energy Meter, which are DC Voltage, Current, instantaneous Power and accumulate Energy consumption. This device is used in DC energy generation or DC load such as Solar PV System. To […]
https://youtu.be/FHdNgxt5_40 Irradiation meter is the device that can measure intensity of sunlight in Watt per meter square (w/m2). Besides using it to describe weather condition, it is a very important and useful device for Solar PV Design. As an experienced Solar PV Designer, we use irradiation meter and its data for 2 purposes: 1) to […]
