The most prominent and important 10 fatal mistakes in the implementation and design of solar energy :
Mistakes in Solar Energy Systems:
- System Sizing:
- Error in calculating the correct size of the system, without taking into account the change in productivity between winter and summer.
- It is necessary to calculate an additional reserve for the panels to avoid weather conditions such as clouds and rain.
- Battery Sizing:
- Failure to take into account the level of discharge (DoD) of batteries and pre-determine their life based on a specific discharge rate.
- Adjusting the vacuum device or inverter to stop the system when it reaches a certain level according to the previous study.
- Wiring:
- Not choosing the thickness of the wires correctly based on the system data and choosing wires with good insulation.
- Use high quality connectors such as MC4 and ensure they are properly insulated to avoid future problems.
- Panel Mounting:
- Use light iron bases that are susceptible to corrosion, which leads to the panels falling and being damaged.
- Prefer to use strong bases that are resistant to weather conditions, such as aluminum bases.
- Waterproofing:
- Failure to insulate panel wires from water, which may cause short circuits or damage to components.
- It is necessary to use good insulating materials and high-quality connectors such as MC4 to ensure proper waterproofing.
- Shading:
- Failure to take into account the effect of shadow, with the need to leave a distance to reduce the effect of objects causing the shadow.
- Use mathematical applications such as Shams to calculate the optimal distance to reduce the shadow effect.
- Inverter and Battery Fuses:
- Not installing DC breakers and fuses for panels and batteries, which leads to an increased risk of accidents.
- It is necessary to install DC breakers and fuses between the batteries and the inverter to protect the system and ease maintenance.
- Inverter installation location:
- Installing the inverter in open places exposed to weather conditions, which leads to damage.
- The inverter must be installed in a cool place free of dust and water to maintain its performance.
- System Grounding:
- Do not use grounding for the system, which exposes the equipment to the risk of damage due to electrical currents.
- There is a need for a grounding system that will protect the equipment and add protection from the harmful effects of lightning.
- Neglecting regular maintenance:
- Leaving the system without regular follow-up and inspection, which may lead to decreased system performance.
- The need to periodically inspect the system’s components and ensure the integrity of the panels and connections on a regular basis.

Gahzly website for purchasing electrical appliances
When we say website, we are talking about one of the most famous Arab websites that was able, in a very short period of time, to achieve a very large demand for purchases from it by people from various parts and sectors of the Arab world.
On the Gahzly website, you will find a joint look and all the products that you may need in your home, starting with those for kitchens or bathrooms, but even those for gardens, you will find them on this wonderful site.
So, if you were lost before and did not know where to go to buy your products on the Internet, now you have the perfect solution, and all you have to do is go to the Gahzly website and start choosing the products you want.
What are the features of Gahzly ?
Since we are talking about a site that is preferred by many people around the world, there is no doubt that it is a site full of various features and characteristics. Therefore, we have decided to devote our next paragraph to pointing out the most prominent features of the Gahzly site.
One of the most prominent features of the site is the proportionality of prices. On the Gahzly website, you do not have to worry about the imaginary prices of the products, as is the case with most sites that display their products on the Internet.
The price of delivering products is very reasonable and not expensive, and the site accepts delivery to various countries, without forgetting that it accepts free shipping on some products.
One of the advantages of the site is also the high quality of its products, as it is impossible to find a poor quality product. Rather, the Gahzly website deals with major companies, Philips, for example, and other famous brands, so you must remove from your mind the idea of the poor quality of one of the products. Another advantage of the site is that it does not specialize in one type of product, but rather you will find various types of products on it, for example, electrical appliances, hand tools, mechanical devices, paints, packages for establishing apartments, and many other types.
Gahzly website also accepts what is known as the shopping cart, which makes it easy for you to filter the products you want to buy and put them in one package in order to be able to pay with the click of a single button.
Accepts multiple payment methods.
