Solar System Energy
The main reason that many people don’t use solar energy is because they are not aware of what all it has to offer. Thsi being stated that they are not aware of what all products are available that can be used with the help of solar energy for an average home. In fact, you can install solar energy systems that range from small portable systems for your vacation home to large permanent solar energy systems that are built right into your home as either a standalone system or a grid system. It is this wide-ranging versatility coupled with the fact that it is a renewable easily available power source that makes it such a great thing.
You can start out small with individual systems such as solar water heater,solar shower, solar lighting, solar fans. That is not all these days we also have solar radios,cookers,purification system. Solar energy is far more useful as it can be used to recharge your batteries and you can also power up every single appliance in your house with the help of the right solar system. It is just a matter of determining where you want to utilize it.
Solar energy can be used in your garden or home. By using it in multiple places around the household you can cut your power bills significantly. There are a multitude of uses for solar energy around the household. It can be used to recharge your batteries, phone and other small appliances. Once you discover solar energy for the home, you will realize that you can power up virtually any electrical appliance or machine with the right solar energy system and supplies.
In diesem Video wird davor der Energieinhalt des Akkupacks von 12,5Wh bestimmt. Anschließend wird es mit einem 40 Watt Ventilator belastet und die Zeit gemessen. 7 Zellen mit jeweils 500mAh halten im Test circa 15min bei 40 Watt Leistung durch, was einen Energieinhalt von 10Wh ergibt.
Dabei handelt es sich um schlechte Zellen mit niedriger Kapazität.
Die für meinen späteren Hausspeicher selektierten Zellen haben gut die 4-fache Kapazität, also um die 2000mAh.
