Understanding Solar Power Rating

Solar technology is already becoming the world’s fastest-growing energy technology. Over the years, it has become a popular choice for many businesses and organizations that seek greener energy and saved energy bills. A sought-after type is the look of the photovoltaic panels. Today, solar panel technology can absorb and convert energy. It harnesses the power of solar radiance to produce electricity.

The principle of photovoltaic solar power explains that an electric current occurs when electrons are displaced. It uses photovoltaic panels with different cells that produce the direct current, converted to alternating current by an inverter. These solar panels can be used in small systems and large plants.

How are solar panels made?

The summary list of a solar panel comprises solar cells, solar cell sealant, back sheet, frame, cover, and cabling. The silicon used in solar panels is in a crystalline silicon (c-Si) form. It is a material that conducts electricity. After doping the silicon, it is covered by an anti-reflective coating which is followed by a completed solar cell made for protection. The sealed solar cells are gathered together onto a back sheet. Finally, a non-corrosive material frame covers the solar panel to prevent dust or rainfall from penetrating.

However, there is more to solar panel technology in terms of its setup and types. Many solar panels up for sale are listed according to their power ratings in watts. The solar power ratings are made to indicate the power potential of a solar panel. Before committing to solar technology, it is vital to understand solar panel output, wattage, and setup. Then, you can build your solar power system through its ratings.

How are solar panels rated?

All solar panels have an efficiency rating. This critical measure can help you determine which solar panels to buy. There are types, namely monocrystalline, poly-crystalline, and amorphous solar panels. The monocrystalline is the most efficient type of solar panel. It has become the industry standard for home solar setups. They are more efficient than polycrystalline or amorphous solar panels.  Although amorphous are lighter and more portable, the monocrystalline type still leads in the market. Aside from its capacity, other factors affect a solar panel’s generation, such as its size, location, and weather conditions.

Size of solar panel

Domestic solar panels consist of conditions of individual solar cells. These solar or photovoltaic cells are where the process of turning the sun’s light into electrical energy takes place. Home solar panels comprise either sixty or seventy-two solar cells. Inside each of the photovoltaic cells are two discs of differently charged silicon joints together in a way that forms an electric field. Sometimes, these solar panels have more than panels. The extra panels mean that it has higher power output. At AceVolt, you can get fast charging that would work effectively.

Weather conditions

A solar panel produces more power in the summer months when the days are longer. It allows more sunshine hours for efficiency. The sun hours refer to the number of peak sun hours you get in your geographical location. While the sun might shine bright during the day, you might only access four or five peak sun hours on that day. The Peak sun hours are those hours when the intensity of the sunlight is at its highest. Although if it gets too hot, solar panels can overheat and generate a lot less power. A shade isn’t advisable because it could reduce how much electricity it can generate.


The direction of the panels plays a significant role in their efficiency. Different parts of the country see more of the sun than others. Usually, a solar panel works best when installed on a southward-facing roof at a 35-degree angle. The southward direction is not shaded at any point of the day.  Also, solar panels can work better even when facing east or west on the roof but between 10 and 60-degrees.

How much solar output do you need?

The most important of the solar rating is its power output. Each solar panel has a power rating, expressed in watts. The higher the solar panel’s wattage, the higher the electricity produced. When searching for accurate solar output, you need to ask yourself these questions. Do I need a solar panel for my home or organization? How much electricity will I use? How many of my appliances would I like to power?

If your household has a high energy usage, we recommend getting solar panels from AceVolt. We have increased output of around 200W per panel. The output of a solar panel is calculated by multiplying the wattage of each solar panel by the total number of panels. For instance, if a home uses 250-watt solar panels by four solar panels. The home would enjoy (250*4 = 1kW solar system).

What does solar panel wattage mean?

 Although most solar panels are around 100W - 400W, the wattage rating represents the solar panel’s expected power production in one hour of ideal conditions. For instance, most residential solar panels are built to produce between 250 and 400 watts per hour. The higher the solar panel’s wattage, the more powerful and long-lasting it is. The wattage rating is known by multiplying a panel’s peak power voltage by its peak power amperage (Pmax = Vmpp * Impp) or (Watts = Volts * Amps). The voltage represents the charge of electricity generated by the solar panels when operating at full potential. The amp rating refers to the flow rate of that electricity.

Other ratings of solar power quality

Power tolerance

How much solar energy can your solar panel tolerate? Solar panels are rated for power tolerance. It measures the degree that panels vary from their standard power output. Better panels with lower power tolerance offer you more confidence in meeting your energy targets.


The best solar panels are the ones that operate for a long time in real-world conditions. Getting a durable solar panel is vital if your solar system will be subject to extreme weather or other out-of-the-country conditions.

Heat tolerance

Solar panels have a temperature coefficient that tells you how much their efficiency is affected by temperatures over 77-degree F. It is crucial to choose a solar panel with a good heat tolerance rating if you live in a very scorching place.

How to test solar panel output

Panels of solar variety are rated according to Standard Testing Conditions (STC). This testing is carried out in a laboratory, not in an open space. It is calculated at 1 atmosphere or ATM accepted at a standard number of 1,013,250 dynes per square centimeter. It is how much all different air particles are bouncing and blocking the sun’s light from getting to us for solar. When the sun is overhead, it goes through less atmosphere. After producing these solar panels, they are flash tested at the same conditions for comparable numbers.

Final thoughts

 Solar technology is constantly advancing all the time. While it is very vital to watch out for the power ratings, other factors to watch out for are also the size, wattage level, output level, positioning, sunshine peak hours, amongst many others. There are many things to take charge of to make your solar panels work at their fullest potential. Whether the solar panel is for your home or organization, you deserve the best solar technology offers. Purchase the right one from AceVolt today!
