A Short History of Solar Power
People have been using the sun's power for thousands of years, but solar technology as we know it today has a more recent history:
​
Ancient Times:
​
Romans and Greeks used the sun to heat buildings and water
They designed homes to capture sunlight during winter
​
Modern Solar Development:
​
1839: French scientist Edmond Becquerel discovered the photovoltaic effect (how sunlight creates electricity)
1954: Bell Labs created the first modern solar cell that could power everyday electrical equipment
1970s: Solar panels started appearing on homes during the energy crisis
1980s-1990s: Solar technology improved but was still very expensive
2000s-Present:
​
- Prices dropped dramatically (about 90% cheaper than in 2000)
- More efficient panels were developed
- Many more homes started using solar power
- Government programs helped make solar more affordable
​
Today, millions of homes worldwide use solar panels, and the technology keeps getting better and cheaper. In fact, solar is now often cheaper than traditional electricity in many places.
Solar Technology Past/Present/Future
What have been the major issues and challenges in the development and implementation of Solar Energy?
Related, but to be dealt with after the major issues and challenges, what have been (and will be) the key technology developments since 1954's Bell Labs created the first solar cell?
Finally in this part of the discussion, what will be the future technical developments foreseen in producing renewable energy?

Needed lots of space for panels
​
Implementation Challenges:
​
Power companies weren't always supportive
Building codes needed updating

Solar Technology Cost and Productivity
Is Solar Power the least cost, highest productivity energy source and why or why not?
In general, this is a difficult question to generalize, but we'll answer this complex question about solar power's costs and productivity in simple terms.
Solar Power Cost Comparison
​
Initial Costs (Installation):
​
Solar is expensive upfront (like buying 10-15 years of electricity at once)
Current costs: $15,000-$25,000 for an average home system
BUT: Government incentives can cut this cost by 30% or more
​
Long-term Costs (Operation):
​
Advantages:
​
Sunlight is free
Very low maintenance costs
Systems last 25-30 years
Can increase home value
Many areas offer money for extra power sent to grid
Disadvantages:
May need battery storage ($10,000+)
Occasional cleaning and maintenance
Might need roof improvements
Insurance costs may increase
​
Comparing to Other Energy Sources
Cheaper Than Solar:
​
Natural Gas
​
Currently cheaper per energy unit
Lower installation costs
But prices can change suddenly
Creates pollution
​
Nuclear
​
Very efficient once built
Low fuel costs
But huge building costs
Safety concerns
​
Hydroelectric
​
Very low operating costs
Long-lasting
But limited by location
Environmental impacts
​
Productivity Factors
Solar Advantages:
​
Works almost anywhere
No fuel needed
Clean energy
Low maintenance
Getting more efficient every year
Solar Limitations:
Only works during daylight
Weather dependent
Needs good roof or land space
Seasonal changes affect output
​
The Bottom Line:
Solar is NOT currently the least expensive or most productive energy source for all situations. However, it's becoming more competitive each year because:
​
Solar costs keep dropping
Traditional energy costs keep rising
Technology improvements make panels more efficient
Environmental benefits are valuable
Long-term savings can be significant
Energy Independence in a tumultuous world in and increasingly desirable and sought after option.
​
Best Situations for Solar:
​
Sunny climates
Areas with high electricity rates
Places with good solar incentives
Homes with good sun exposure
When long-term ownership is planned​
