Solar Module Descriptions: 

Solar Power Modules (known as Photovoltaics - PV) can generate electricity for your home or business, either as part of a stand-alone solar power system, or for buildings already connected to the local electricity network.

PV systems use the most abundant energy source on the planet, solar radiation, to generate electricity. They are silent, consume no fuel and generate no pollution. They also contribute to the reduction of greenhouse gas emissions; a 2kW PV system on a house will prevent the emission of about 40 tonnes of CO2 during its projected 30 year lifetime. Furthermore, the use of PV will reduce your electricity bills and exposure to fluctuating and steadily rising electricity prices.

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:
A solar controller prevents overcharging of batteries by regulating the flow of electricity from the solar panels to the batteries. It continuously monitors the battery voltage and adjusts the charging current accordingly, ensuring that the batteries are charged at the optimal level and preventing any excess energy from damaging the batteries due to overcharging.
Q:
To monitor the performance of your solar controller, you can follow these steps: 1. Check the display: Most solar controllers come with an LCD display that shows important information such as battery voltage, charging current, and load status. Regularly monitor this display to ensure everything is functioning properly. 2. Utilize monitoring software: Some solar controllers are compatible with monitoring software that allows you to connect your controller to a computer or smartphone. This software provides detailed data and analytics on the performance of your solar controller, including energy production, battery health, and charging efficiency. 3. Monitor battery voltage: Keep an eye on the battery voltage to ensure it remains within the optimal range. If the voltage consistently falls below or exceeds the recommended levels, it may indicate a problem with the solar controller. 4. Observe battery charging and discharging: Monitor the charging and discharging cycles of your battery to ensure they are occurring at the expected rates. If there are irregularities or inconsistencies in these cycles, it could indicate a malfunctioning solar controller. 5. Conduct regular inspections: Physically inspect the solar controller for any signs of damage, loose connections, or abnormal heat generation. These could be indicators of performance issues that need to be addressed. Remember, monitoring the performance of your solar controller is crucial for optimizing energy generation and ensuring the longevity of your solar system.

Additionally, the solar controller monitors and controls charging and discharging rates to ensure the longevity and health of the batteries. Consequently, a solar controller is an integral part of the system that allows for the efficient operation of solar-powered indoor office buildings.
Q:
A solar controller handles variations in load power requirements by continuously monitoring the amount of power needed by the load and adjusting the flow of energy from the solar panels accordingly. When the load power requirement increases, the solar controller increases the flow of energy from the solar panels to meet the demand. This is usually achieved by increasing the duty cycle of the controller, allowing more energy to be transferred from the panels to the load. Conversely, when the load power requirement decreases, the solar controller reduces the flow of energy from the solar panels to avoid overcharging the batteries or wasting excess energy. It achieves this by decreasing the duty cycle, limiting the amount of energy transferred from the panels to the load. Solar controllers also employ various algorithms and control mechanisms to optimize the balance between energy generation and load consumption. These algorithms may include maximum power point tracking (MPPT) to ensure that the solar panels operate at their most efficient point, as well as voltage and current regulation to protect the batteries and load from potential damage. Overall, a solar controller plays a crucial role in managing the power flow between solar panels and the load, ensuring that variations in load power requirements are handled efficiently and effectively.
