Classification of concrete foundation ground mounted pv systems

图片
There are many types of concrete foundation  solar mounting structures  for ground power stations. According to different project geological conditions, the corresponding installation methods can be selected.The following mainly introduces the most common types of cast-in-place reinforced concrete foundations, independent and strip concrete foundations, and precast concrete hollow column ground solar mounting foundations. 1.Cast-in-place concrete piles and cast-in-place anchor rods. Advantages: Small amount of earthwork excavated from cast-in-place reinforced concrete foundation, low cost and fast construction speed. Disadvantages: The construction of cast-in-place reinforced concrete foundation is subject to environmental factors such as season and weather, and has high construction requirements. Once completed, it cannot be adjusted. 2.Independent and strip concrete foundation Advantages: Independent and strip concrete foundation adopts reinforced extended foundation, simple...

Solar lights basics: how do they work?

  Solar lights  work like a miniature version of a rooftop solar panel system with one important distinction: solar lights must include battery storage. During the daytime when the sun is shining, solar cells attached to the light generate electricity and store it in a battery. Most solar lights include a darkness sensor so that come night time, they will automatically turn on and start using their stored electricity. While many solar lights have their solar cells built right into the same unit as the light itself, some products will have lights separate from the solar panel providing power to it. Most solar lights are LEDs that only use a small amount of electricity. Because of this, many solar lights can run for a full night (if not more). Most solar lighting systems have a “nightly run time” rating that indicates how long you can expect lighting given a certain amount of sun exposure. Keep in mind that these run times will vary significantly from the actual lighting time yo...

Introduction of photovoltaic carport system

How to fully utilize the land of a parking lot? Maybe the photovoltaic carport can help you. The photovoltaic carport is mainly composed of solar panels, carport brackets, inverters and other equipment. The carport solar systems not only realizes the original function of "shading and avoiding rain" of the carport, and plays a role of "protection and cooling" for vehicles, and can also convert solar energy into alternating current and integrate it into the grid. It can provide single parking spaces, double parking spaces, and row parking spaces. It is mainly used in corporate parking lots and large ground parking lots. It not only makes outdoor parking lots more beautiful, but also can supply power to the grid, save energy and protect the environment. The foundation of  carport mounting system  is also relatively diversified. There are pile foundations, cement foundations, and the most direct ground as the foundation. It will not be too limited to the impact of the l...

4 things to know about solar panels

1. Solar panel systems are a great way for you to save money, no matter what your budget is. If you can afford to pay your electricity bill every month, you can afford to install a solar panel system. With a $0-down solar loan, solar lease, you can finance your system and see immediate savings. ​ 2. Installing a solar panel system is a great investment. Investing in a solar panel system can deliver better returns than stocks and bonds – and now is the right time to make that investment. While solar photovoltaic technology is improving incrementally each year, financial incentives and rebates will decrease as solar becomes more popular. 3.Solar power systems are practically maintenance-free. Solar panel systems are incredibly durable. Except in extreme circumstances, they don't need to be washed or cleaned. 4.Solar power systems can eliminate most of your electricity bill. With the right planning, your solar panels can generate enough electricity to meet your needs over a 12-month p...

Advantages and disadvantages of flat roof solar mounted PV bracket

Reasonable photovoltaic support foundation can improve the wind load resistance and snow load resistance of the solar pv mounting systems. Rational use of the characteristics of  solar mounting structures , we can further optimize its dimension parameters, save materials, and make contributions to further reduce the cost of solar racking system. The following is a comparative analysis of the advantages and disadvantages of different foundation. 1.Cement pier foundation support Flat roof concrete foundation support is currently the most commonly used installation form in flat roof solar power stations. According to the form of foundation, it can be divided into strip foundation and independent foundation; the connection between the support column and the foundation can be connected by anchor bolts or directly embedded the columns into the concrete foundation. Advantages: Good wind resistance, no damage to roof. Disadvantages: Long construction period. 2.Concrete ballast bracket Ball...

How do you maintain your solar panels of solar street light?

图片
Worried about solar panels and hail? Fret not, solar panels are incredibly durable and require little to no maintenance over their productive lifetime – which can span 25 years or more. Solar panels are made of tempered glass, so they’re built to withstand hail and other rough weather. With the exception of tracking mounts, solar panel systems don’t have movable parts, which cuts down on the possibility of any problems. Many people in regions that get significant snowfall often ask if it’s necessary to remove the snow from the panels. Generally, the answer is no – snow usually melts and falls from the panel shortly after falling, so it doesn’t have a big impact on your overall production levels. For your panels to be self-cleaning, they will need to be mounted at an angle of 15 degrees or more. Generally, solar panels don’t need to be cleaned. If you live somewhere where there is a lot of smog, dust, or dirt, you may see a dip in your production over time that can be remedied by cleani...

The Advantage of Solar Street Light

图片
Solar street lights   are independent of the utility grid resulting in lessened operation costs. This means that these are wireless lights and are not connected to your electricity provider. The lights are dependent on the heat energy given off by the sun, storing as much of it throughout the day. Solar street lights require less maintenance than conventional street lights. These have lower chances of overheating. Since solar wires do not have external wires, the risk of accidents is minimized. A lot of times, accidents happen to the personnel who fixes the street light. These can include strangulation or electrocution. Solar street lights are environment-friendly because its panels are solely dependent on the sun hence eliminating your carbon footprints contribution. Some parts of solar street lighting systems can be easily carried to remote areas, making these more efficient and handy solutions to lighting problems.   On the other hand, if there are advantages, solar street ...
