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 with the fulfillment of daily needs.
Solar energy is a form of renewable and clean energy, which makes it environmentally friendly and safe – 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 water and can be used in the operation of simple electrical appliances.
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 climates than polycrystalline panels that work more efficiently in warmer climates.
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, 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.
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 and rapid development that is happening in this area. While the cost of solar energy for an ordinary apartment is 200 kilowatts, or nearly $2400, it is worth mentioning that this cost is not continuous, but it lasts for 20 years or more. In other words, you won’t have to pay an electricity bill for 20 years, making it an economic transition as well as a sustainable one. The price of solar power equipment has also decreased from $6,000 to $1500 in recent years.
Even though it might be a large amount to pay once-off, investing in renewable and sustainable energy sources is the way forward to a cleaner, greener planet.
