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:What is the purpose of the low voltage disconnect feature on a solar controller?
The purpose of the low voltage disconnect feature on a solar controller is to protect the batteries from over-discharge. When a battery is discharged below a certain voltage level, it can cause irreversible damage and significantly reduce its lifespan. The low voltage disconnect feature monitors the battery voltage and disconnects the load, such as appliances or devices, from the battery when the voltage drops below a predetermined threshold. This helps to prevent the battery from being drained too much and ensures that it retains enough charge for proper functioning and longevity. By disconnecting the load, the low voltage disconnect feature helps to safeguard the battery and optimize its performance in a solar power system.
Q:Can a solar controller be used with a solar-powered office building?
Yes, a solar controller can be used with a solar-powered office building. A solar controller regulates and optimizes the flow of electricity between the solar panels and the building's energy system, ensuring efficient and safe operation. It helps manage the charging and discharging of batteries, protects against overcharging or overvoltage, and monitors the overall performance of the solar power system in the building.
Q:Can a solar controller be used with solar-powered air pollution monitoring stations?
Yes, a solar controller can be used with solar-powered air pollution monitoring stations. A solar controller helps regulate and optimize the charging and discharging of batteries in a solar-powered system. Since air pollution monitoring stations often rely on solar power as their primary source of energy, a solar controller is essential to ensure efficient and reliable operation by managing the flow of power from the solar panels to the batteries and monitoring the charging process.
Q:What is the maximum current that a solar controller can handle?
The maximum current that a solar controller can handle depends on its design and specifications. It can range from a few amps to several hundred amps, depending on the size and capacity of the controller.
Q:How does a solar controller prevent overcharging of batteries?
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:How does a solar controller handle lightning strikes or power surges?
A solar controller typically includes built-in protection mechanisms to handle lightning strikes or power surges. These protection features can include surge suppressors, transient voltage suppressors, and grounding systems. These components help divert excessive voltage and current away from the solar controller, minimizing the risk of damage caused by lightning strikes or power surges.
Q:Can a solar controller handle power fluctuations from the generator?
Yes, a solar controller can handle power fluctuations from the generator. The solar controller acts as a regulator and converter, ensuring a stable and consistent flow of power to the connected devices or batteries. It can effectively handle variations in power input from the generator, adjusting the charging or discharging rates to maintain a steady output.
Q:Can a solar controller be used with portable solar panels?
Yes, a solar controller can be used with portable solar panels. A solar controller helps regulate and optimize the charging process, protecting the batteries from overcharging and maximizing the efficiency of the solar panels. It can be particularly useful when using portable solar panels to ensure a consistent and reliable power source for various devices or appliances.
Q:How do I determine the maximum load output power for a solar controller?
To determine the maximum load output power for a solar controller, you need to refer to the specifications provided by the manufacturer. The maximum load output power is typically stated in the product manual or datasheet. It is important to check for the maximum load output power rating to ensure that it can handle the power requirements of your specific load or device.
Q:What is the role of a solar controller in maximizing solar panel efficiency?
The role of a solar controller in maximizing solar panel efficiency is crucial in ensuring optimal performance and protection of the solar panel system. Solar controllers, also known as charge controllers or solar regulators, are responsible for regulating the flow of energy between the solar panels and the batteries or electrical loads. One of the main functions of a solar controller is to prevent overcharging of the batteries. As solar panels generate electricity, they continuously charge the batteries. However, if the batteries are overcharged, it can lead to damage and reduced lifespan. The solar controller monitors the battery voltage and ensures that the charging process is controlled and optimized, preventing overcharging and extending the battery life. Moreover, solar controllers also protect the batteries from deep discharge. When the batteries are not being charged, they can discharge power back into the solar panels, causing damage and reducing overall efficiency. The solar controller prevents this by disconnecting the solar panels from the batteries when the voltage drops below a certain threshold, preserving battery capacity and preventing damage. Additionally, solar controllers play a role in maximizing the efficiency of the solar panels by maximizing the power output. They employ Maximum Power Point Tracking (MPPT) technology, which allows the solar panels to operate at their maximum power output regardless of changes in temperature or shading. MPPT technology continuously adjusts the voltage and current to find the optimal operating point for the solar panels, ensuring that they are always producing the maximum amount of power possible. In summary, the role of a solar controller in maximizing solar panel efficiency is to regulate the flow of energy, prevent overcharging and deep discharge of batteries, and employ MPPT technology to optimize the power output of the solar panels. By performing these functions, solar controllers ensure that the solar panel system operates at its highest efficiency, maximizing the generation of clean, renewable energy.
