FAQ
Q: What kind of loads can I run on PV?
With a correctly designed PV system you can power almost any electrical load. However, as the load size increases the expense also increases. Loads like hot water heaters, air conditioners, room heaters and electric stoves should be avoided. The added cost of trying to power loads like these is very cost prohibitive. If these loads have to be powered it will be a lot less expensive to change the appliance to use an alternative fuel type like propane.
Q: When do I need a charge controller and why?
The safest way to figure out if you need a charge controller is to take Battery Amp Hour Capacity and divide this by the Solar Panel max. power amp rating. If the quotient is above 200, you don't need a controller. If the number is less than 200 than you need a controller.
For example if you have a 100 amp hour battery and a 10 watt panel, you take 100 and divide it by .6 (600mA) and you get 166.6. Since this is less than 200 you need a charge controller. If you have a five-watt panel in the above example you take 100 divided by .3 (300mA) and you come up with 333.3. Since this is larger than 200 you do not need a charge controller. However you still need a blocking diode, to prevent the battery from discharging to the panel at night. So as a general rule of thumb you don't need a charge controller unless you have more than five watts of solar for every 100-amp hours of battery capacity.
Q: What is PV & how does it work?
PV stands for photovoltaic. Photo = Light and Voltaic = Electricity. A solar cell converts light to electricity.
A solar cell is made of silicon. Computer chips are made of this same material. Basically, when light strikes the surface of a solar cell some of it is absorbed into the silicon. This light energy bumps the electrons loose and causes energy to flow.
By packaging approximately 36 solar cells together a solar panel or a solar module is created. When you have more then one solar panels you create a solar array.

- Q: What are the temperature compensation features in a solar controller?
- Temperature compensation features in a solar controller are designed to ensure optimal performance and efficiency of the solar system, regardless of the ambient temperature. These features help to counteract the effects of temperature fluctuations, which can significantly impact the charging and discharging processes of the solar batteries. One of the main temperature compensation features is the ability to adjust the charging voltage based on the temperature. As the temperature increases, the voltage required to charge the batteries effectively decreases to prevent overcharging. Conversely, as the temperature decreases, the charging voltage needs to be increased to compensate for the reduced battery efficiency. Another important temperature compensation feature is the ability to adjust the load disconnect voltage based on temperature. This feature ensures that the batteries are not discharged excessively in extremely cold temperatures, which can lead to irreversible damage. By raising the load disconnect voltage in colder temperatures, the solar controller protects the batteries from being drained beyond safe levels. Furthermore, temperature compensation features can also include temperature sensors that measure the ambient temperature and relay this information to the controller. This allows the controller to continuously monitor the temperature and make real-time adjustments to the charging and discharging processes. Overall, the temperature compensation features in a solar controller play a crucial role in maintaining the performance and longevity of the solar system. By accurately adjusting the charging voltage and load disconnect voltage based on temperature, these features help to optimize the efficiency and reliability of the solar system in various weather conditions.
