When solar panels do not produce energy, it takes longer to recoup their installation and maintenance cost. In countries that rely on expensive solar power, this could result in a severe disadvantage compared to those that don't or can't use solar power. Scientists need to discover more efficient semiconductors to make solar power production more efficient.
Solar energy is an abundant, reliable, and pollution-free power source. However, the expensive cost and inconsistent availability are major problems that have prevented it from becoming more widely used.
Another major advantage of solar energy is that it is renewable; this form of energy is sustainable and, quite literally, endless. Other advantages of solar panels include, but are not limited to, their diverse application and their low maintenance costs. The installation of solar panels is also creating new jobs in the renewable energy sector.
Balancing is tricky because solar energy doesn’t flow around easily like fossil fuels. The following technical challenges are the most common in grid-tied systems: Voltage Regulation: Rapid changes in solar power can cause the voltage to fluctuate, potentially harming appliances and affecting people’s health.
One reason for the lack of widespread support for solar power from consumers is the significant initial investment outlay. However, large solar farms built in desert regions have helped reduce installation costs by creating a larger economy-of-scale (parts, materials, and installation people are in one location).
The sun offers the most abundant, reliable and pollution-free power in the world. However, the expensive cost and inconsistent availability are problems preventing solar energy from becoming a more widely used energy source.

Problems with Solar Energy
Solar power makes up less than 0.5% of all power produced in North America even though there are vast regions of the continent where the sun continuously shines. To harvest more of this free energy, we need to discover new materials, develop new production techniques and solve the problem of storing energy when the sun isn''t shining.

Why Are Solar Panels So Inefficient?
In a world where fossil fuels have been so widely used, why are solar panels not more efficient? As it turns out, there is a good reason why solar cells aren''t used in all applications. In general, producing energy through photosynthesis is an astonishingly inefficient process. One reason why producing energy through photosynthesis is inefficient is because energy from photons of blue …
