When we say solar energy, it means all the applications that are used to convert this energy into energy that generates electricity and replaces it in feeding the needs of daily needs. Solar energy is a form of renewable and clean energy, which makes it an environmental safety feature because it does not pollute the atmosphere and the technologies used are simple compared to other sources of energy. This energy helps to heat homes and heat the water and can be used in the operation of simple electrical appliances.
Solar energy is renewable and clean energy, but what about the cost of installation?
There are two main types of panels used:
- Mono panels
- Polycrystalline panels
The difference is that mono panels work more efficiently in cold areas than polycrystalline panels that work more efficiently in hot areas.
The capacity of the single panel is between 100 and 350 watts, and the more widely used panels produce 250 watts. The price of a 250-watt polycrystalline board is between $ 130 and $ 200 per solar panel, but the price may vary depending on other criteria such as manufacturer name, plate quality and even warranty conditions. Here we have to mention that 4 combined panels can generate 1 kW, so the cost of one kW is between $ 520 and $ 800 for lifespan.
Cost per watt
The cost of one watt of electricity in solar energy is about $ 1.6 and this figure is decreasing with the continuous development that is happening in this area. While the cost of solar energy for an ordinary apartment is 200 kilowatts, or nearly $ 2400, and it is worth mentioning that this cost is not simple, but it lasts for 20 years or more. So, you as a person will not pay the electricity bill for 20 years
In addition to the fact that the price of solar power equipment has decreased from $ 6,000 to $ 1500.
