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:Can a solar controller be used with a generator or other backup power sources?
Utilizing a solar controller with a generator or alternative backup power sources enables the regulation of electricity flow from solar panels to the battery bank. This guarantees efficient battery charging and safeguards against overcharging or battery damage. The solar controller remains useful when employing a generator or other backup power sources, managing the electricity flow from solar panels to the battery bank. This seamless integration between solar and backup power sources optimizes battery charging and safeguards against potential damage. Incorporating a solar controller with a generator or alternative backup power sources enhances the overall efficiency and reliability of the energy system. The solar controller ensures effective battery charging, regardless of the power source utilized, and maximizes the utilization of renewable energy from solar panels.
Q:How do I ensure proper grounding for a solar controller?
To ensure proper grounding for a solar controller, you should follow these steps: 1. Locate a suitable grounding point: Find a metallic structure, such as a grounded metal rod or a metal pipe, preferably close to the solar controller installation site. 2. Clear the grounding area: Remove any dirt, paint, or rust from the chosen grounding point to ensure a good electrical connection. 3. Connect the ground wire: Use a copper conductor or a grounding cable to connect the grounding point to the ground terminal on the solar controller. Make sure the connection is tight and secure. 4. Avoid sharp bends: Ensure the ground wire is not bent sharply, as this can impede the flow of electrical current. Instead, maintain gentle curves or use grounding clamps to navigate around obstacles. 5. Protect the ground wire: Safeguard the ground wire from physical damage or exposure to moisture by using conduit or other suitable protective measures. 6. Test the grounding: After installation, use a multimeter to verify that the ground wire is properly connected and has low resistance to earth. This will ensure that the solar controller is effectively grounded. By following these steps, you can ensure proper grounding for your solar controller, which helps protect against electrical surges and improves system safety and performance.
Q:Can a solar controller be used with solar-powered indoor healthcare institutions?
Solar-powered indoor healthcare institutions can benefit greatly from the use of a solar controller. This crucial component of a solar power system plays a vital role in regulating the charging and discharging of batteries and controlling the flow of electricity from the solar panels to connected devices or appliances.

Q:How can I determine the size of solar controller I need for my system?
To determine the size of the solar controller you need for your system, you should consider two main factors: the maximum current and voltage of your solar panels. First, calculate the maximum current your panels produce by dividing the wattage rating by the voltage rating. Then, choose a solar controller that can handle this maximum current and voltage. It's always recommended to select a controller with a slightly higher capacity to allow for potential future expansions or efficiency losses.
Q:Can a solar controller be used with a solar tracker?
Yes, a solar controller can be used with a solar tracker. A solar controller is responsible for regulating the charging and discharging of batteries in a solar power system, while a solar tracker helps to maximize the efficiency of solar panels by following the sun's movement. By integrating a solar controller with a solar tracker, the system can effectively manage the power generated by the solar panels, ensuring optimal performance and battery charging.
Q:Can a solar controller be used with a solar-powered off-grid cabin?
Yes, a solar controller can be used with a solar-powered off-grid cabin. A solar controller regulates and optimizes the charging of batteries from solar panels, ensuring efficient energy storage and preventing overcharging.
