There are several problems with solar energy. Most of these problems though are being solved. Solar energy has come a long way in just the last few years.
1. Cost - the single largest hurdle solar energy faces is that competing energy sources have always been cheaper in terms of dollars per kilowatt-hour (a standard measure). Compared to electricity from coal-fired power plants, solar is more expensive - if you don't consider the environmental costs (which typically are hard to asses a dollar amount to).
But in recent years solar power is becoming closer and closer to grid-parity on price especially with the introduction of new types of solar panel chemistry like Cadmium telluride.
2. Site suitablity - many sites don't receive enough solar energy to make solar energy cost effective. Cloudy areas with frequent rain are often not as well suited for solar panels because typically solar panels need direct sun to produce the most power. That's changing though, new panels can now use diffuse light on cloudy days to still produce power. With prices going down steadily, more sites would be feasible that once were not.
3. Embodied energy - It takes a tremendous amount of energy to produce a solar panel. Because of this - depending on the type of panel and the way it was made - the panel itself may have required 11 years worth of its energy production just to make it. So if that's the case, the panel won't begin making 'new' energy until it has been operating for 11 years. It takes energy to make them, and you can think of this like taking out an 'energy loan' and so the loan must be paid back before an 'energy profit' can be made. Again, this is changing, new panels are made more efficiently, and require less material than older technologies so the 11 years is highly dependent on the type of panel and the manufacturing process.
4. Production and Demand - Typically solar panels produce the most energy during the middle of the day and somewhat less before and after than. Also, solar panels produce the most power during the summer. To the extent that demand for power does not coincide with this production curve, other sources of energy must be used to fill in, or some sort of storage (like batteries) is needed.
5. Materials - The material used to make solar panels is in short supply or the supply has fluctuated. This, again, depends on the type of panel, some panels don't have this problem. Shortages in materials mean it can be hard for producers to meet demand - thus pushing up the cost - which is the main stumbling block for the adoption of solar energy.
A question about solar energy could be: what is solar energy?: what does solar energy do?:does solar energy do anything for the earth/planet?
You may need a large surface; it is expensive; and you have to store energy for when the Sun doesn't shine.
You can use solar energy to power your house. You will need to get solar panels to convert solar energy to usable energy.
Solar energy is energy that comes from the sun.
My wife's dog, Bea, was just diagnosed with a pre-cancerous tumor on her abdomen caused by lying in the sun. There are other problems.
A major problem with solar energy is if the sun is not out, you have no energy.
use a battery
The main one is that at night it doesn't work

Solar energy, while being quite useful, can also have it's own problems. For example, how does solar energy work if you occupy a place that rains most of the time? The sun is never out so, no solar-power. Furthermore, the rate of efficiency with solar panels is only 40%, is it worth all the money that is paid for them?
the suns energy is solar energy because sun means solar so solar energy is from the sun
Solar energy is inexhaustible. Solar energy is not pollution. Solar energy can be used anywhere on Earth.
Solar systems get their energy from the sun. Solar energy is captured by a solar panel, or collector. This panel converts solar energy to electrical energy.

because then it would be to easy to solve all of our problems.
