How Do Solar Panels Work?

We all know that a solar panel converts solar power into electrical energy. However, many people do not understand what goes on in the process. This section will equip you with the knowledge of how a solar panel works. So how does a solar panel work?


Solar panels have many photovoltaic cells. The cells convert the sunlight into electricity and are made from semiconductor materials like silicon.


The semiconductor material conducts electricity and maintains the electrical imbalance necessary to create an electric field. When the light falls on the solar panel, the photons are absorbed, knocks off several electrons, and later freely drifts in the cell.


The solar cell comprises electrons and protons sandwiched to create an electric field. Drifting electrons are forced to flow towards several conductive metal plates that line solar cells by the electric field. The flow is called energy current. The strength of the energy current determines the amount of electricity produced by each cell.


Upon hitting the metal plate, the current is directed into wires into an inverter. The solar panel generates DC. However, most appliances need alternating current.


The inverter converts the DC into usable AC power and ensures you can use it for daily use. If there is any unused power, it is transferred into the grid via the utility meter. That is how solar panels produce electrical power from solar power.

Pros and Cons


  • Reduction in electricity bills

Among the most well-known advantages of using a solar panel is that it reduces the cost of electricity bills. By producing your power using solar panels, you reduce the expenses of buying electricity from the grid. The money saved can cater to other things. In addition, solar power is both free and renewable. Therefore, you will not incur any additional costs producing it.


  • Solar energy is renewable

Solar power is an example of green energy. You can use energy repeatedly without getting used up. The sun produces a vast amount of energy daily. Solar panels help you harness a portion of that energy for your uses without ever being depleted.


Therefore, anyone can use solar power with the help of a solar panel. With a solid budget, you can shift to solar power and never pay for electricity bills again. Solar power is also clean. Hence, you can use it without worrying about pollution or the emission of greenhouse gases.


  • Low cost of maintenance

With daily improvements in solar technology, it is becoming easier to maintain solar panels. Long-time warranties on the panels and workmanships are also included, easing the maintenance of solar panels on your end. You only have to call the vendor, and they will handle the maintenance for you.


The other routine maintenance is wiping and removing the dust from the solar panel. It ensures that the conversion rate remains high throughout.


  • Selling the surplus to the grid

The other advantage of solar panels is that they can produce surplus energy you can sell on the grid. Therefore, solar panels can make you some extra cash. Besides the money, you give your community renewable and clean solar power.


The government offers tax incentives and tariffs for the excess energy they produce. While these tariffs vary depending on the state, the two main ones are fixed-rate tariffs and time-varying tariffs. You get paid based on the Kilowatts, enabling you to see the return on investments on your solar panels.



  • High initial cost

The initial cost of purchasing and installing solar panels is high. Therefore, some homeowners may not afford it.


  • Dependence on weather

As we have already seen above, solar panels turn sunlight into electrical power. It means that if the light intensity is affected by your location, rain, or cloudy skies, you will not have enough power.


  • Low conversion rates

Solar panels convert sunlight into electrical power at low rates. However, the most advanced solar panels convert only 20-25% of solar energy into electrical energy. It means that there still is room for improvement in solar panel technology to harness the full power of solar energy.


  • You cannot use it in areas that receive low sunlight and at night

The efficiency of solar panels in converting solar power into electrical energy also depends on the light intensity. Therefore, they cannot harness the power at night or in places that experience low light from the sun.


Buyer’s Guide: What To Know

Power output

Power is the whole reason you are investing in a solar panel. Therefore, you must consider how much power it produces. Can you connect two or more solar panels to generate more power?


Many 100W solar panels feature an MC4 power output. It means the average watt-hours would be at least 420Wh per day. It is the amount of power that you get that determines what appliances the solar panel can power.



The other thing to consider is the runtime. How long does the solar panel take to power your appliances? How long does it take to charge the solar battery?


On average, a 100-watt solar panel produces 8.33amps for every peak sun hour. Therefore, to charge a 100Ah solar battery, for instance, the solar panel may take 13 hours.


However, factors like the rate of discharge on the appliance, temperature, and weather can affect a 100-watt solar panel’s runtime. So buy a solar panel that can run electrical appliances such as your air conditioner for a longer time.



The next thing to consider is the compatibility of our 100W solar panel with batteries. Batteries are essential because they store surplus power. The higher the battery capacity, the more you can store energy. However, the battery should not be too big compared to the solar panel.


A bigger battery requires a larger solar panel in terms of power. Otherwise, charging the battery might take too long. The power input should roughly match the power output.

For one 100W solar panel, a 100Ah 12V battery may be enough. You can use a lead-acid battery or a lithium-ion battery (that we recommend).



What will you be powering with your 100W solar panel? One 100W solar panel can run several small devices. These include a ceiling fan, lamps, smartphones, and any other device whose power rating is below 90W. A 100W solar panel cannot run your air conditioner continuously.


Before you buy a 100W solar panel, it is critical to calculating the total power requirements of your appliance. It will help you decide whether to buy one or two 100W solar panels.



As we have already seen, the weather is a critical determinant of the amount of power produced by a solar panel. Consider the weather of your area before purchasing a 100W solar panel. It will help you calculate the KWh and decide whether to add another solar panel. A solar power calculator can help you decide.


If the area experiences less sunlight, you may have to rely partly on the power from the grid. If the solar panel is for a tailgate or camping in areas that do not receive enough sunlight, you can charge the battery and carry it fully charged.



Does the solar panel have any safety implementations? Regardless of the source, electrical power is dangerous. Therefore, the solar panel should have a solar charge controller that protects the appliances from overcharge, short-circuiting, and undercharge. In addition, it protects you and your electrical devices from any harm.


The panel cables should be insulated. It also should come with pre-drilled holes for safe fastening on the roof of your RV or house. The power station that you buy should also feature a solar charge controller.



The other thing to consider before buying a 100W solar panel is its price. 100 Watt Solar panel price can start above $100 for a 100 Watt solar panel. These are usually sold individually or in packages of 2 panels.  If you do not have a solar power station (AKA Solar power generator) for your panels, consider adding one to your cart before checkout to ensure you have both the power generator and the solar panels. The power generator can start in the mid $200-300s and up for a 100W small portable solar power generator.


Frequently Asked Questions (FAQs)

Can you power a home with 100W solar panels?

Yes, you can run home with 100W solar panels. However, it is not a wise financial decision. A home consumes much energy and needs a system that can generate between 5,000-10,000 Watts. To make such a system using 100W solar panels, you may have to connect between 50-100 such solar panels.


Installing such many solar panels means that you have a complicated system because of additional framing, fasteners, and raking. Such many solar panels mean that you have more electrical connections, making the system unreliable. You get less watt/dollar in such a setup. So is it worth it to use 100W solar panels to power a home? It is not. Consider a home standby generator as a backup source to power the whole house.
