Generators are not so. After installation, a generator will require regular servicing by a professional every 6 months.
Although the first solar power cell was made with gold and selenium, it was much more inefficient than the silicon solar power cells of today.
Solar panels are cheap to use because there are no fuel expenses like in electricity generators.
Solar panels are often warranted to maintain 80% of their efficiency for up to 25 years. Other parts will need to be replaced sooner, but if all goes well there should be no maintenance costs at all for the first five years.
A common misconception about solar power is that it is only useful during the day, but because this power can be stored, this solar energy can be used in homes even on cloudy days or at night.
Today you can even buy an air conditioner that is powered by solar cells during sunny days and at night you can run it from the backup batteries, which are recharged the next day.
To reduce the cost of solar power a cell needs to be created that is efficient and useful enough for consumers everywhere.
However the biggest issue with solar power is it's reliability. Ideally you need a location that gets plenty of sun throughout the year.
Other natural resources are also being explored as renewable energy resources such as wind power and water, however water generation is limited to areas where there is a sufficient flow to operate turbine generators.
The solar energy systems are easy to maintain. They do not involve high costs or too much effort, thus letting you reap the benefits of the solution comfortably.
