benefits of solar energy
1. Renewable energy source
Among all the advantages of solar panels, this is the most important.Solar power is a truly renewable energy source.🇧🇷 It can be used in all regions of the world and is available every day. usThe sun's energy cannot run outunlike other energy sources.
Solar power will be available for as long as we have sun, so sunlight will be available to us for at least 5 billion years when scientists say the sun will die.
2. Reduce electricity bills
Since it covers part of its energy needs with the electricity generated by its solar system, itsthe electricity bill will go down🇧🇷 What you save on your bill depends on the size of the solar system and your electricity or heat consumption.
For example, if you are a company that usescommercial solar panelsThis option can have huge benefits as the large size of the system can cover much of your energy bill.
In addition, you not only save on your electricity bill, but you also have the opportunity to do so.Receive excess energy paymentswhich exports back to the grid via thesmart export guarantee(MON). If you generate more electricity than you consume (assuming your solar system is connected to the grid).
3. Various applications
Solar energy can be used for various purposes. you can generateelectricity(photovoltaic) ocordiality(solar thermal🇧🇷 Solar power can be used to generate electricity in areas without grid access, to distill water in regions with limited freshwater supplies, and to power satellites in space.
Solar energy can also beintegrated into the materials used for buildings🇧🇷 Not too long ago, Sharp introduced transparent solar power windows.
4. Low maintenance costs
solar systems in generaldoes not need much maintenance🇧🇷 You just need to keep them relatively clean, so it's okay to clean them a few times a year. In case of doubt, you can always count on specialized cleaning companies that offer this complete service.£ 25- £ 35.
The offer of the most reliable solar panel manufacturers20-25 yearsTo guarantee.
Since there are no moving parts, there is no wear and tear. The inverter is usually the only part that needs to be replaced later.5-10 yearsbecause it works continuously to convert solar energy into electricity and heat (Solar photovoltaic vs. solar thermal🇧🇷 In addition to the inverter, the cables must also be maintained in order for your solar power system to work at maximum efficiency.
Once you cover the initial cost of the solar system, you can expect a lot.low maintenance costand repair work.
5. Technological development
technology in the solar industryis constantly evolving andimprovementswill intensify in the future. Innovations in quantum physics and nanotechnology could potentially increase the effectiveness of solar panels and double or even triple the electrical power input of solar power systems.

Disadvantages of solar energy
The cost of buying a solar systemis quite high. This includes payment for solar panels, inverters, batteries, wiring and installation. Still, solar technologies areconstantly evolvingTherefore, it can be assumed that prices will fall in the future.
2. Weather dependent
Solar energy can still be collected on cloudy and rainy days, but the efficiency of the solar system decreases. solar panels aredependent on sunlightcollect solar energy effectively. Therefore, some cloudy and rainy days can have a noticeable impact on the electrical system. You should also be aware that solar energy cannot be collected at night.
On the other hand, if you need to keep your water heating solution running overnight or in winter,thermodynamic panelsare an alternative to consider.
To find out how effective solar panels are in the winter, watch our video:
3. Solar energy storage is expensive
Solar energy should beused the same, or may bestored in large batteries🇧🇷 These batteries, used in off-grid solar systems, can be charged during the day for power at night. This is a good solution to use solar energy throughout the day, but it is also quite expensive.
In most cases, it's smarter to keep it simple.Take advantage of solar energy during the day.and drawing power from the grid at night (this is only possible if your system is connected to the grid). Fortunately, your power needs are usually higher during the day, so you can cover most of them with solar power.
4. It takes up a lot of space
The more electricity you want to produce, the more solar panels you will need, since you want to collect as much sunlight as possible.photovoltaic solar moduleneed a lot of spaceSome ceilings are not big enoughto match the number of solar panels you want to have.
An alternative is to install some of the panels in your garden, but they must have access to sunlight. If you don't have space for all the panels you want, you may choose to install fewer to meet some of your energy needs.
5. Linked to pollution
Although pollution from solar power systems is much less compared to other energy sources, solar power can be linked to pollution. The transportation and installation of solar panels has been linked to greenhouse gas emissions.
there are some tootoxic materials and dangerous goodsused during the manufacturing process of solar energyphotovoltaic systemsthat may indirectly affect the environment.
still solar energypollutes much lessthan other alternative energy sources.
