One of the important ways to support solar panel against water damage is the pitched roof or pitched mounting structure, which your solar installer will take care about when setting up your solar system, surely he will take care of adjusting the solar panel slant, to push rains water out, preventing it from staying on solar panel surface for a long time, so keeping solar panel internal structure safe and without harm. A second way to improve waterproof feature of the solar panel is to raise the waterproof seal (a barrier keeping the water out).
Due to the large power consumption of air conditioning, electric fan has become a popular choice for solar energy users. It's nice to watch TV with a cool breeze in summer, but how many solar panels do you need? Compared with air conditioning, fans consume less power and will not divert too much power during operation.
Electric vehicles and portable solar panels are undoubtedly the perfect combination. With the rapid decline of renewable energy costs, is it unreasonable to combine the two? In summer, you can expect solar panels to generate more energy, so charging the battery will be faster. In winter, less sunlight is available, so the charging time will be longer.
Is your solar panel as efficient as before? Before calling customer service, please check the cell for leaves, dirt, dust or bird droppings. It usually takes only one thorough cleaning to get the system running again. Although the maintenance cost of solar systems is low, don't ignore them. Here are some tips to keep solar panels clean when they look and run.
The solar inverter with all of its different types constitutes as the second most important part in solar system, because its responsible of major main jobs. It is responsible of the safety, quality and quantity of the AC output power (AC electricity) generated for the solar system, and its responsible of AC output power optimization at different conditions the solar system encounters over the day and year, so it plays an important role in increasing the electrical energy harvest.
In normal operation and in general, the solar panels do not generate noise, as they are manufactured and designed to be noise free equipment, especially in night time, but even at day time where the sun hits the solar panel and it works to generate electricity, there will not be a noise.
The connection of the solar photo-voltaic system to the power grid has multiple ways, based on electric utility regulations, and solar system owner installation purpose.
One of these connection ways is the gross metering scheme. In this scheme, the whole electricity generated form the solar photo-voltaic system will go directly to the grid, and not to our home. So, all the harvest will be sent back to the grid on a pre-determined feed in tariff we agreed for with our local electricity supplier.
In photo voltaic Solar system, there are 2 positions of installations we have to take care about in order the solar panels can produce most of their rated power, in other word, we can get the max generation efficiency of our solar panels when we properly install them in two positions. The first position is the orientation of the solar array, we mean to point out the solar array to the sun directly, whether the array will face north, south, or whatever based on the country location, we just aim to get a best position to collection most of sun radiation over the day and the year.
The working principle of solar power system is basically the same. Solar panels absorb the energy of the sun. It is converted into electrical energy and stored in batteries. The inverter converts current into power compatible with electronic equipment. But can you connect the solar panel directly to the load? Sometimes you can, sometimes you can't.
To get the most accurate estimate, you must consider the size of the battery and how many hours of sunlight is available. A 40 watt solar panel can provide 40 watts of electricity per hour. This is the maximum output you can expect, but depending on the weather, it may fall below this value.
The installation process of solar panels must be carried out correctly to obtain the maximum solar panel system, otherwise your panels will not achieve their maximum efficiency. In order to let you know the installation process of solar panels, please follow the 7-step guide.
If you want to replace the inverter and get the largest unit, you can afford it. Whether you are on the grid or not, the larger the capacity is better than the smaller the capacity. It's also easy to find the ideal size. There are several questions that need to be answered. The most important are the following.
A 120 watt solar panel can supply power to various appliances and equipment as long as their power is less than 120 watts per hour. If you have a USB mobile phone charger, you can use it to charge your mobile device and free up this panel for other applications. The solar panel can run any load as long as it is within the capacity range.
Safety rules will guide in making our whole solar system to be well cabled together and having the appropriate and correct size protection devices/fuses, in addition to good labeling and the existing of the operating manuals for all solar system components according to international and local standards.
Net Metering is one of the dominant arrangements the electricity company dealing us in billing when we install our new solar photovoltaic system. Under this arrangement, the electricity generated from the solar inverters and the solar photovoltaic system will go to feed our home (electrical loads) at first, and then the additional excess generated electricity which is not required by our home electrical appliances/loads will be exported to the power grid.
In some kind of solar photo voltaic system called Off Grid system, your solar system will incorporate batteries that can feed your loads with electricity in case of low sun radiation and night time. But such batteries add a significant cost to your solar system, so it is usually recommended to be used in remote areas in where there is No regular electricity supply exists.
The energy metering system is an important component in our solar system, because it tells us how much electricity our solar system generates, how much electricity our electrical appliances and equipment are using and the amount of electricity we are still buying for the power utility or export to the power utility after connecting our solar system to the power grid.
Actually there are three main types of solar panel in the market, and they differ between each other mainly in 3 parameters: Efficiency, capability to withstand high environment temperature, and capability to deal with diffused sun light.
After installing our new solar photovoltaic system, our electricity consumption from the electric grid may be changed, resulting in new / modified electricity consumption pattern. Also, as a result we may be subjected to a new metering regulations according to our country rules. The question is: Will there be a tariff change due to our new solar system installation? The answer for this question will be provided by your electricity retailer. Moreover, we have to get the answer for this question even before installing our solar panel power inverter, so we can weigh up the dis-advantages and advantages of the new installation before making our decision.
When Solar System company/installer design our solar photo-voltaic array, they specify two standard slopes: The first is the orientation which means the solar panels face direction, whether it will be to North, South, East or West, and the second is tilt angle which means the solar panel angel with horizontal surface "roof angle". Ideally, solar panels should face the south, and the tilt angle should equal to the solar system location latitude, so we can get maximum electricity production from our solar phot-voltaic system.
