1. Residential solar panels emerged in the 1800's.
2. The first "true" solar panels were created in the 1950s.
3. Solar cell's efficiency may be as few as 4% (organic cells) or around 40% (experimental multiple-junction solar cells). The higher the efficiency of the material, the more expensive it will likely be to manufacture it.
4. One 100W light bulb that's constantly on, costs around $100 per year.
5. One photovoltaic roof shingle can produce around 15W of electricity. Several solar roof shingles could run one 100W light bulb that's constantly on.
6. A solar cell with 10 percent efficiency output and a 100 sq centimeters (15.5 sq inch) surface can produce about 1W of power.
7. An average household uses about 9,000kWh of energy annually.
8. A 350 Sq foot panel that produces 15W of power per Sq foot would produce a total of about 9,000kWh of energy yearly, which could power an average household with all the current energy that it needs.
9. An average homeowner that uses electricity from their utility grid could spend $50,000 next 25 years on their electric bills.
10. Tax incentives for buying solar is as high as 30% of the purchased solar powered system's cost.
11. The united states, tax incentives can lead to shortening the time for the panels to pay back for themselves down to as few as 6-8 years.
12. You may get solar panels for free from homeowners or businesses upgrading their systems.
13. Solar panels typically have a 20-25 year warranty and 40 year lifetime expectancy.
14. To have the best from solar panels, they should be facing south and be installed at 20-50 degree angles.
15. You can wire solar cells to increase the Voltage of the system (series wiring), to increase the Current of the system (parallel wiring), or to increase both, Voltage and Current (series/parallel wiring).
16. Solar powered systems with a battery can provide a homeowner with electricity even during local power outages.
17. You don't have to connect a home in the woods to a power grid, if you provide it with a powerful enough solar power generator.
18. Solar energy is very safe for the environment, since it produces negligibly small quantities of elements, and only along the way of manufacturing the solar materials.
19. Later on, we may see cars and houses painted with a translucent solar paint to generate energy.
20. Solar energy won't run out until the sun ceases to shine, which is estimated to happen in about 5 billion years from now.
As you have seen, a lot of good solar energy facts. It's also a fact that the world is anticipating further drops in the price tag on solar material, so that everyone can enjoy the many solar power benefits at a reasonable cost.
