Assuming ideal conditions, a 40-watt solar panel will charge a 100 amp hour battery in approximately 40 hours. In reality, however, conditions are rarely ideal and it will likely take significantly longer to charge the battery. Factors such as the…
You’ve probably seen solar panels on top of buildings and wondered how they work. Solar panels are made up of many smaller units called photovoltaic cells. These cells convert sunlight into electricity. The electricity can then be used to power…
There are a few things to consider when deciding if you can charge a solar battery from the grid. The first is the type of solar battery you have. If you have a lead-acid battery, it is not recommended to…
If you’ve recently purchased solar lights and they’re not working, there are a few things that could be the issue. Sometimes it’s simply a matter of making sure the batteries are charged. Other times, it may be that the solar…
In cells, electrical energy is converted to chemical energy. This process is known as cellular respiration. Cellular respiration occurs in the mitochondria of cells. The mitochondria are the powerhouses of the cell and they convert electrical energy into chemical energy…
Energy is transferred into sound in a number of ways. When an object vibrates, it produces sound waves. The energy from these vibrations is transferred to the surrounding air, which then carries the sound waves to our ears. Sound is…
A 25 watt solar panel can take anywhere from 8-16 hours to charge a 12V battery depending on the size of the battery, weather conditions, and if the panel is being used alone or in conjunction with other panels. If…
There are a few things you need to consider when choosing what size solar panel to charge a 200Ah lithium battery. The first is how much power you need to generate each day. This will depend on your daily energy…
In Texas, solar energy is a hot topic. With the state’s high electricity rates and abundant sunlight, many people are wondering if solar power is worth the investment. There are a few things to consider when making the decision to…
Solar garden lights are a great way to add light to your garden without having to worry about running electrical cords or expensive monthly bills. But, just like any other type of outdoor light, solar garden lights can be susceptible…
