While the question “How many batteries do I need for my refrigerator?” lacks a one-size-fits-all answer, sizing a battery bank for your refrigerator is a straightforward process when you consider the following factors: The energy consumption of your refrigerator. The desired duration for which the battery bank should…
Running your refrigerator on solar power is quite feasible since fridges consume a relatively low amount of energy. However, it’s important to note that relying solely on solar panels won’t be sufficient to make this project a reality. To run a refrigerator on solar power, you would need…
Compared to other types of air conditioners, such as window AC units and ducted air conditioners, mini-splits are pretty energy-efficient, in the sense that they use less power (kW) and consume less energy (kWh) to perform the same amount of heat exchange. Even so, mini-splits are still air…
The amount of electrical energy (kWh) that a solar panel produces over a certain period of time depends on the amount of sunlight that it has received over that same period. Reversibly, the size of the system that you need to produce a certain amount of energy (2000…
So, you have a 12 Volt battery and a refrigerator, and you’re wondering “how long will the battery run the refrigerator?“. Now, due to the many factors involved (ambient temperature, usage, age, type, and size of the refrigerator, etc..), there are no general or 100% accurate answers to…
In this article, I’ll help you put the electricity production capabilities of a 200 Watt solar panel into perspective, first, by answering some of the most frequently asked questions on the topic, such as: How much Electrical Current (Amps) does a 200 Watt solar panel produce? How much…
300 Watts of solar power is a great starting point for anyone looking to harness the abundant and free power of the sun. But, what exactly can a 300 Watt solar panel run? How much electrical energy can it produce? and how does this energy production compare to…
Solar panels can be a pretty consistent source of energy, but when it comes to exactly how much energy that is, it is important to set your expectations right. To do that, it is important to understand the difference between Power (Watts) and Energy (Watt-hours), and what each…
Electricity measurement units can be very confusing and are often misunderstood, this is mainly because electricity itself is a complicated subject. In my article about Electricity and its measurement units, I discuss Amps, Volts, Watts, and Watt-hours. In this article, I’ll explain what kW and kWh are, what…
Fuses and circuit breakers are what you call overcurrent protection devices (or OCPDs for short), and their job is to disconnect the circuit in case the current (in Amps) exceeds a certain threshold. This allows them to protect the wires and the equipment if – for any reason…
