Solar energy is obtained from solar radiation. However, solar radiation is free, solar energy is not free. Converting solar radiation into solar energy involves cost and technology. Like any other technology, there are disadvantages of solar energy.

Disadvantages of solar energy
1. You need a lot of space
The biggest disadvantage of solar panel systems is the large footprint of solar panels and models. Rooftop home solar panel systems require a large space to install solar panels. In addition, the area must be shadow-free and receive good sunlight. The direction must also be in the right direction to maximize the output.

For commercial use, a large amount of land is needed to generate enough solar electricity for transmission and distribution.

2. High initial costs
Another big drawback of solar panel systems is the initial installation cost. For home solar panel systems, the initial installation cost is about $2 per watt.

So, if you need to generate 500 watts of solar energy, then the cost is probably around 500 * 2 = $1,000. A 1 kilowatt home solar panel system with batteries can cost around $2,000.

3. Solar energy is prohibited at night and on cloudy days
This is another disadvantage of solar panel systems. It requires constant exposure to sunlight to produce energy. The system will not produce any energy at night and will not reach its full potential on cloudy days. At this time, the energy stored in the battery will be used.

4. Less solar energy in winter
In winter, it is very cold and the sun is not very bright. The same is true in areas that are too cold. During this time or place, the system will not reach its full potential.

5. Dc equipment is expensive
Solar panels produce direct current (direct current from sunlight). This electricity can be used directly to run DC running appliances. But such appliances are more expensive than those that use alternating current.

However, an inverter can be used to convert DC to AC.

6. Expensive batteries
Solar energy generated by solar panels can be stored in batteries and used when needed. But the downside is that these solar cells are currently too expensive. The cost of a solar cell depends on its capacity (ah) and warranty. Also note that tubular batteries provide better backup, last longer, and have a longer warranty. As a result, they cost more than flat-panel batteries. The price also depends on the brand.
