Among all the benefits of solar panels, the most important is that solar energy is a truly renewable energy source. It can be utilized in all regions of the world and can be used every day. We cannot exhaust solar energy, unlike some other sources of energy.
As long as we have the sun, we can obtain solar energy, so the sunlight can be used by us for at least 5 billion years, and according to scientists, the sun is about to die.
As you will use the electricity generated by your solar system to meet some of your energy needs, your energy bill will decrease. How much you save on the bill will depend on the size of the solar system and your electricity or heat usage.
For example, if you are a company using commercial solar panels, this conversion can have huge benefits because a large system scale can cover a large portion of your energy bill.
In addition, not only can you save on electricity bills, but you may also receive payment for the remaining energy exported back to the power grid through Smart Export Guarantee (SEG). If you generate more electricity than you use (considering that your solar panel system is connected to the grid).
Solar energy can be used for diverse purposes. You can generate electricity (photovoltaic) or provide heat (photothermal). Solar energy can be used to generate electricity in areas without an energy grid, distill water in areas with limited clean water supply, and power satellites in space.
Solar energy can also be integrated into the materials of buildings. Not long ago, Sharp introduced transparent solar windows.
Solar systems generally do not require extensive maintenance. You only need to keep them relatively clean, so clean them a few times a year. If in doubt, you can always rely on specialized cleaning companies, who provide this service for approximately £ 25-35.
Most reliable solar panel manufacturers offer a 20-25 year warranty.
Additionally, there is no wear due to the absence of moving parts. The inverter is usually the only component that needs to be replaced after 5-10 years, as it is constantly working to convert solar energy into electrical and thermal energy (solar photovoltaic power generation and solar thermal energy). In addition to inverters, cables also require maintenance to ensure that your solar power generation system operates at maximum efficiency.
Therefore, after paying the initial cost of the solar system, you can expect to spend very little on maintenance and repair work.
The initial cost of purchasing a solar system is quite high. This includes paying for solar panels, inverters, batteries, wires, and installation costs. However, solar energy technology is constantly developing, so it is certain that prices will decrease in the future.
Although solar energy can still be collected on cloudy and rainy days, the efficiency of solar systems will decrease. Solar panels rely on sunlight to effectively collect solar energy. Therefore, several cloudy and rainy days will have a significant impact on the energy system. You should also consider that solar energy cannot be collected at night.
On the other hand, if you also require your water heating solution to work at night or in winter, a thermal power plate is an option to consider.
Solar energy must be used immediately or can be stored in large batteries. These batteries used for off grid solar systems can be charged during the day to use energy at night. This is a good way to use solar energy all day, but it is also quite expensive.
In most cases, it is wiser to use solar energy during the day and obtain energy from the grid at night (only when your system is connected to the grid). Fortunately, your energy needs are usually high during the day, so you can use solar energy to meet most of your needs.
The technology in the solar energy industry is constantly improving and will be further improved in the future. The innovation of quantum physics and nanotechnology has the potential to improve the effectiveness of solar panels, doubling or even doubling the power input of solar power generation systems.
By choosing solar panels, you not only reduce your energy costs, but also have a positive impact on the environment.
